Acute corneal decompensation after silicone oil removal.

PURPOSE: To assess acute corneal decompensation after silicone oil removal in some aphakic eyes with clear corneas whose anterior chambers were completely filled with silicone oil for a considerable period of time. METHODS: Eight eyes of 8 patients who underwent vitrectomy and intraocular silicone oil injection were studied. All the eyes were aphakic and anterior chambers were completely filled with silicone oil. In all eyes, corneas were clear and no corneal finding indicating keratopathy was detected by slit-lamp microscopy before silicone oil removal. The mean silicone oil removal time was 4 months (range 2-7 months). A specular microscope was used for the evaluation of corneal endothelial changes and corneal pachometry was performed to observe corneal changes before and after the silicone oil removal in 5 eyes besides slit-lamp microscopy. The follow up period after silicone oil removal was 2-12 months (mean 6 months). RESULTS: In all eyes severe corneal stromal edema and clouding was detected in the first day following silicone oil removal. Increased corneal thickness was seen in all eyes. Decreased (at or below critical levels) corneal cell density was detected by specular microscopy before and after silicone oil removal. No significant improvement was observed during the follow up period. CONCLUSION: Eyes whose anterior chambers completely filled with silicone oil could be evaluated as clear corneas by slit lamp microscopy despite severe endothelial damage. We recommend that eyes with silicone oil in the anterior chambers should be monitored by a combination of slit-lamp microscopic examination and specular microscopy to determine the relative corneal endothelial tolerance to the silicone oil and endothelial damage. Early removal of the silicone oil can be considered when the retinal adhesion allows.

In vivo microstructural analysis of the cornea in Maroteaux-Lamy syndrome.

PURPOSE: This report describes the clinical and in vivo microstructural features of the cornea in a case of Maroteaux-Lamy syndrome. METHODS: A 17-year-old female with Maroteaux-Lamy syndrome was examined by slit-lamp biomicroscopy, Orbscan II slit-scanning elevation topography, and in vivo confocal microscopy. RESULTS: Slit-lamp biomicroscopy revealed bilateral, altered corneal transparency involving the posterior half of the stroma. Funduscopy revealed bilateral small, crowded optic discs, and radial macula retinal folds. On in vivo confocal microscopy, the middle and posterior stroma were clearly visualized and exhibited well-defined, unusually shaped keratocytes. These cells contained single or multiple hyporeflective regions with well-defined borders that ranged from 1 to 11.6 microm in diameter. These abnormal keratocytes were particularly abundant in the posterior stroma and sparse in the anterior stroma. CONCLUSIONS: This is the first case of Maroteaux-Lamy syndrome in which altered corneal transparency has been imaged by in vivo confocal microscopy and macula retinal folds have been described.

Efficacy of topical chloramphenicol and tobramycin ophthalmic solutions in preventing severe Staphylococcus aureus keratitis in rabbits.

Various marketed chloramphenicol ophthalmic solutions were compared and various dilutions of Tobrex Ophthalmic Solution were tested for effectiveness in a Staphylococcus aureus rabbit keratitis model. Anesthetized rabbits were each infected intracorneally with 10(4) Staphylococcus aureus ATCC 29737 cells. Treatment groups consisted of five or six rabbits (10 or 12 eyes) per group. One group of rabbits was infected but not treated (Positive Control Group). Topical dosing of commercially available ophthalmic solutions was accomplished by depositing 0.1 mL of a color-coded test solution into the lower cul-de-sac of each eye. Dosing begin one hour after the mid-infection time and continued for a total of nine hourly treatments. Twenty-four hours after infection the rabbit eyes were graded (masked) using standard slit-lamp scoring procedures. The slit-lamp scores for five of eight ocular parameters were used to calculate an eye score value for each rabbit eye. The five ocular parameters were selected, based on previous Stepwise Discriminant Computer Analysis of over 300 rabbit eyes infected with Staphylococcus aureus ATCC 29737 and treated with various antibiotics. The eye score values for each group were averaged and the treatments were compared for significant differences in efficacy using the nonparametric, Wilcoxon-Mann-Whitney Rank Sum Test.(ABSTRACT TRUNCATED AT 250 WORDS)

Is screening with digital imaging using one retinal view adequate?

PURPOSE: To compare the detection of diabetic retinopathy from digital images with slit-lamp biomicroscopy, and to determine whether British Diabetic Association (BDA) screening criteria are attained (>80% sensitivity, >95% specificity, &<5% technical failure). METHODS: Diabetics referred for screening were studied in a prospective fashion. A single 45 degrees fundus image was obtained using the nonmydriatic digital camera. Each patient subsequently underwent slit-lamp biomicroscopy and diabetic retinopathy grading by a consultant ophthalmologist. Diabetic retinopathy and maculopathy was graded according to the Early Treatment of Diabetic Retinopathy Study. RESULTS: A total of 145 patients (288 eyes) were identified for screening. Of these, 26% of eyes had diabetic retinopathy, and eight eyes (3%) had sight-threatening diabetic retinopathy requiring treatment. The sensitivity for detection of any diabetic retinopathy was 38% and the specificity 95%. There was a 4% technical failure rate. There were 42/288 false negatives and 10/288 false positives. Of the 42 false negatives, 18 represented diabetic maculopathy, 20 represented peripheral diabetic retinopathy and four eyes had both macular and peripheral changes. Three eyes in the false-negative group (1% of total eyes) had sight-threatening retinopathy. There was good concordance between the two consultants (79% agreement on slit-lamp biomicroscopy and 84% on digital image interpretation). CONCLUSION: The specificity value and technical failure rate compare favourably with BDA guidelines. The low sensitivity for detection of any retinopathy reflects failure to detect minimal maculopathy and retinopathy outside the 45 degrees image. This could be improved by an additional nasal image and careful evaluation of macular images with a low threshold for slit-lamp biomicroscopy if image quality is poor.

Intraocular pressure difference in Goldmann applanation tonometry versus Perkins hand-held applanation tonometry in overweight patients.

OBJECTIVE: To analyze the increase in intraocular pressure (IOP) caused by anatomic and physiologic factors in overweight patients when using Goldmann applanation tonometry. DESIGN: A prospective cohort study. PARTICIPANTS: Seventy average-weight individuals who had no difficulties with IOP measurements at the slit lamp and 12 obese patients with suspected glaucoma who could position the head at the slit lamp only with great effort participated. INTERVENTION: The authors compared IOP values between slit-lamp-mounted Goldmann applanation tonometry and Perkins hand-held tonometry. MAIN OUTCOME MEASURE: The difference in Goldmann and Perkins IOP measurements was examined. RESULTS: In the group of obese patients, the mean IOP was 20.9+/-2.28 mmHg (mean +/- standard deviation; range, 18-26 mmHg) for the right eye and 21.4+/-3.16 mmHg (range, 16-28 mmHg) for the left eye when determined by Goldmann tonometry and 16.3+/-2.39 mmHg (range, 13-20 mmHg) for the right eye and 16.3+/-2.42 (range, 11-19 mmHg) for the left eye when determined by Perkins tonometry. The mean decrease was 4.5+/-1.3 mmHg (range, 3-7 mmHg) for the right eye and 4.9+/-1.9 mmHg (range, 2-9 mmHg) for the left eye. In the control group, the mean difference between the two types of tonometers for the right eye was 0.34+/-0.69 mmHg and for the left eye was 0.33+/-0.82 mmHg. Patients who had a falsely elevated IOP on Goldmann tonometry had an average body mass index of 34+/-3.82 (range, 28.5-41.9); most were female (5:1 ratio). CONCLUSION: The authors believe simultaneous breath-holding and thorax compression, with subsequent increase in venous pressure, may be a causative factor for transitory elevations of IOP. Perkins tonometry in obese patients may help avoid a false diagnosis of glaucoma caused by transitory elevations in IOP.

Use of viscoelastics post-trabeculectomy: a survey of members of the American Glaucoma Society.

BACKGROUND AND OBJECTIVE: American Glaucoma Society members were surveyed to determine the pattern of use of viscoelastics for anterior chamber reformation at the slit-lamp in the post-operative clinical management of patients who have undergone trabeculectomy in order to give ophthalmologists an indication of how these materials are being used by their colleagues. MATERIALS AND METHODS: We surveyed 196 members of the American Glaucoma Society regarding the following; (1) whether they inject viscoelastic post-operatively at the slit-lamp as an in-office procedure, (2) the type of viscoelastic used most often, (3) the criteria for injection of viscoelastic, (4) the time to first follow-up, (5) the average number of injections, and (6) the occurrence of post-injection endophthalmitis. RESULTS: One hundred twenty-five (64%) of the 196 mailed surveys were answered and returned. Ninety-four (75%) of the respondents reported injecting viscoelastics in the postoperative period at the slit-lamp as an in-office procedure. Healon (60%) (Pharmacia & Upjohn Co, Kalamazoo, MI), Viscoat (17%) (Alcon, Ft. Worth, TX), and Healon GV (7%) (Pharmacia & Upjohn Co, Kalamazoo, MI) were the three most often used viscoelastics. Hypotony, iriscornea touch, and lens-cornea touch were given as criteria for injection 19%, 47%, and 88% of the time, respectively. Range of time to first follow-up was 1 hour to 7 days, with a mean time of 1 day. Range of average number of injections was 1 to 3 with a mean of 2 injections for patients requiring injection. Only one respondent reported an incidence of endophthalmitis. CONCLUSIONS: The use of viscoelastic materials in the postoperative trabeculectomy patient in the office at the slit-lamp for anterior chamber reformation is a prevalent practice. Healon is the most commonly used viscoelastic postoperatively and lens-corneal touch is the most common criterion for injection. The average number of injections is 2, with a mean and mode follow-up time of 1 day. Endophthalmitis is a rare complication.

Contrast sensitivity following focal laser photocoagulation in clinically significant macular oedema due to diabetic retinopathy.

PURPOSE: To evaluate the influence of focal aser photocoagulation on contrast sensitivity in diabetic patients with clinically significant macular oedema (CSMO). METHODS: A prospective non-comparative interventional study was performed on a group of patients with CSMO at Dr Rajendra Prasad Centre for Ophthalmic Sciences, New Delhi, a tertiary eye care centre. Thirteen diabetc patients (14 eyes) with CSMO and no history of prior photocoagulation were recruited for this study. Direct focal photocoagulation of all leaking microaneurysms was performed using an argon green laser (514 nm). A contact lens was used as a slit lamp delivery system. Evaluation of the best corrected Snellen visual acuity, contrast senstivity, slit lamp biomicroscopy, macular status on direct ophthalmoscopy and fluorescein angiography was carried out 1 month and 3 months after laser photocoagulation. RESULTS: Following direct focal laser photocoagulation, focal CSMO resolved completely in all but one eye, 4-8 weeks later, as seen on slit lamp biomicroscopy and/or fluorescein angiography. Post-treatment, visual acuity remained stationary in eight eyes, improved by one line in three eyes, by two lines in two eyes and by three lines in one eye. The mean +/- SD pretreatment and post-treatment decimal visual acuities were 0.49+/-0.30 and 0.59+/-0.28, respectively. The mean +/- SD pre-laser contrast sensitivity score was 121.3+/-83.6, which increased significantly to a mean +/- SD of 151.6+/-80.5 fo lowing direct focal photocoagulation. CONCLUSION: Focal argon laser photocoagulation in CSMO in diabetics helps in improving the contrast sensitivity and stabilizes the visual acuity. The changes in contrast sensitivity and visual acuity are independent of each other.

A pilot study on slit lamp-adapted optical coherence tomography imaging of trabeculectomy filtering blebs.

BACKGROUND: Our study aims to identify anatomical characteristics of glaucoma filtering blebs by means of slit lamp-adapted optical coherence tomography (SL-OCT) and to identify new parameters for the functional prognosis of the filter in the early post-operative period. METHODS: Patients with primary open-angle glaucoma, aged 18 years and older, scheduled for primary trabeculectomy at the Department of Ophthalmology, Radboud University Nijmegen Medical Centre, were considered for our study. All patients underwent standardized trabeculectomy with intra-operative application of mitomycin C. The filtering blebs were evaluated clinically and with SL-OCT on day 1 and 1, 2, 4 and 12 weeks following surgery. The resulting data were analysed and weighed against surgical success. To better understand the SL-OCT data a small comparative histologic study was performed. RESULTS: The study included 20 eyes of 20 patients. After completion of our study, 15 eyes of 15 patients (mean age+/-SD 67 +/- 16 years) were eligible for data analysis and 5 eyes missed at least one follow-up visit. Filtering surgery was considered successful (intraocular pressure < or = 21 mmHg without antiglaucomatous medication) in 11 of 15 eyes. SL-OCT frequently demonstrated multiple hypo-reflective layers within Tenon's capsule ("striping" phenomenon) in the first post-operative week. Presumably, these layers corresponded with drainage channels in the histological specimen. These channels were present in functional filters but not in the failures. In addition, the visualisation of the sclera below the filtering zone was better defined in failures compared with successful filtering blebs ("shading" phenomenon). We observed no differences in the volume and clinical aspect of the blebs in the successful group compared with the unsuccessful group. CONCLUSIONS: Successful filtering blebs show characteristic optical properties on SL-OCT. These phenomena suggest a diffusely enhanced fluid content and the presence of intra-bleb drainage channels in functional filtering blebs.

Anterior chamber depth measurement in clinical practice.

This study compares the validity of anterior chamber depth estimates provided by a slit-lamp technique with those obtained from pachometry and ultrasonography. The technique provides depth estimates which are valid to within +/- 0.33 mm relative to standard pachometry, and to within +/- 0.42 mm relative to ultrasonography. The technique is simple to perform, requires no extra slit-lamp attachments, and may be carried out on any slit-lamp which has a calibrated variable length of slit.

Telemedical evaluation of ocular adnexa and anterior segment.

PURPOSE: To report the accuracy of telemedical slit-lamp evaluation in examination of ocular adnexa and anterior segment. METHODS: By means of contingency tables, slit-lamp findings by live examination and by real-time telemedicine were compared in 50 eyes of 25 patients. RESULTS: Sensitivity percentages (proportion with findings correctly identified by telemedicine)/specificity percentages (proportion without the finding that was correctly identified by telemedicine) were 100/64 for eyelid mass, 100/85 for conjunctival pigment, 100/100 for posterior synechiae, 80/0 for blepharitis, 83/93 for iridotomy, 70/93 for pinguecula, 75/93 for iris lesions, 56/98 for corneal scar, 0/100 for chamber inflammation, 57/93 for nuclear cataract, and 37/100 for intraocular lens presence. CONCLUSIONS: By means of monocular slit-lamp telemedical evaluation, clinical findings with high contrast cues for color and depth have the highest sensitivity and specificity.

Diffuse lamellar keratitis associated with recurrent corneal erosions after laser in situ keratomileusis.

PURPOSE: Diffuse lamellar keratitis (DLK) is marked by the presence of diffuse or multifocal infiltrates confined to the laser in situ keratomileusis (LASIK) interface. These infiltrates are culture-negative, and the etiology is thought to be noninfectious. Most cases of DLK occur within the first week or two following surgery. METHODS: We describe one case of diffuse lamellar keratitis that occurred 3 months after LASIK. The patient developed a spontaneous corneal erosion in one eye. Over the next 2 days while the erosion was being treated, there was rapid development of DLK. Slit-lamp biomicroscopy and in vivo scanning slit confocal microscopy were performed. The patient was treated with intensive topical corticosteroids. RESULTS: Scanning slit confocal microscopy revealed numerous, highly-reflective round bodies consistent with a polymorphonuclear infiltrate located at the flap interface. Treatment with topical 1.0% prednisolone acetate was instituted, with rapid improvement in patient symptoms, visual acuity, and slit-lamp biomicroscopy. CONCLUSIONS: Diffuse lamellar keratitis may occur months after LASIK as a result of a spontaneous recurrent corneal epithelial erosion.

Ophthalmic telemedicine at the Alabama Institute for Deaf and Blind.

BACKGROUND: The University of Alabama at Birmingham School of Optometry and the Alabama Institute for Deaf and Blind have collaborated in development of electronic medical records, digital slit-lamp medical imaging, and ocular telemedicine between their two sites. METHODS: The telemedicine link uses the electronic medical record system (EMRS) called PEARL, and digitized slit-lamp images made with an MCV 4000 digital imaging unit attached to a Topcon SL4E slit-lamp. RESULTS: These technologies allow remote physician access to medical records as well as remote triage of eye problems using transmitted digital images and telephone consultation. CONCLUSIONS: This implementation strategy can serve as a model for improvement of specialist access to remotely located sites. It is a unique pairing of a school of optometry and a residential institution for people with sensory impairment.

Intravitreal toxicity of garenoxacin.

PURPOSE: To assess the retinal toxicity of varying concentrations of intravitreally injected garenoxacin. METHODS: Twenty eyes of 20 New Zealand albino rabbits were used for this study. The animals were anesthetized with ketamine (35-50 mg/kg) and xylazine (3-5 mg/kg). Garenoxacin was titrated using distilled water to the following concentrations: 4,000, 2,000, 1,000, 400, 200, and 100 microg/0.1 mL. Each concentration was injected intravitreally (0.1 mL) into three rabbit eyes. Three control eyes were injected with 0.1 mL of balanced saline solution. All animals were examined before and after injection by indirect ophthalmoscopy and slit-lamp biomicroscopy. Electroretinography was performed on all animals before intravitreal injection and 14 days after injection. The animals were examined by indirect ophthalmoscopy and slit-lamp biomicroscopy before they were killed; the eyes were enucleated and examined with light microscopy. RESULTS: No electroretinographic changes or signs of retinal toxicity by slit-lamp examination, indirect ophthalmoscopy, or light microscopy were seen in any eyes 14 days after intravitreal injection of garenoxacin (< or =4,000 microg/0.1 mL). CONCLUSIONS: Garenoxacin injected intravitreally appeared safe at concentrations of < or =4,000 microg/0.1 mL.

Methods of assessment of patients for Nd:YAG laser capsulotomy that correlate with final visual improvement.

BACKGROUND: This paper attempts to clarify the usefulness of various simple pre-operative measures in estimating the potential for a visually successful capsulotomy. METHODS: 24 patients attending for capsulotomy had pre-operative measures of glare with BAT tester, visibility of posterior pole and grading of posterior capsular pearls and fibrosis seen at slit lamp. Visual function was measured before and after standardised capsulotomy. Correlations of the various preoperative measures with eventual visual function improvements were calculated. RESULTS: Pearls at slit lamp and poor posterior pole visualisation were all correlated with improvements in visual acuity and contrast sensitivity after capsulotomy. Amount of fibrosis visible at slit lamp and glare assessment were not correlated with vision improvements after laser. CONCLUSION: Of the various measures that are taken prior to Nd : YAG capsulotomy, some correlate with eventual visual improvement but for others no clinical utility was found. Practitioners should note these findings as they are especially of use in more questionable or high-risk cases to help determine whether referral for PCO treatment by Nd: YAG capsulotomy is likely to benefit the patient.

Optical coherence tomographic assessment of diabetic macular edema: comparison with fluorescein angiographic and clinical findings.

PURPOSE: To compare the optical coherence tomographic (OCT) features with clinical and fluorescein angiographic (FA) findings in patients with diabetic retinopathy. METHODS: In a retrospective study ophthalmologic examination together with FA and OCT images were obtained from 195 eyes of 110 patients with different stages of diabetic retinopathy and OCT images were obtained from 40 eyes of 20 control subjects. Fluorescein leakage characteristics were organized into five groups: no leakage (1), focal (2), diffuse (3), combined focal+diffuse leakage (4) and cystoid (5). The Pearson correlation test was used to test the correlation between visual acuity and central foveal thickness and ANOVA was used for the statistical comparison between the groups. RESULTS: The OCT images demonstrated retinal swelling in 66.1% of eyes, cystoid macular edema (CME) in 11.8% of eyes, serous foveal detachment + swelling in 6.2% of eyes, serous foveal detachment+swelling+CME in 3.6% of eyes and normal foveal structure in 12.3% of eyes. The best-corrected visual acuity was significantly correlated with central foveal thickness (r:-0.528, p<0.01). There was 77% agreement between clinical examination and OCT results. CME was detected with OCT in 15.4% of eyes in our study, 40% of which was not detected with slit-lamp biomicroscopy and 63.3% of which was not evident in FA. None of the serous foveal detachments could be detected during slit-lamp biomicroscopy or FA. CONCLUSIONS: OCT-3 provided objective documentation of foveal structural changes in eyes with diabetic retinopathy. Best-corrected visual acuity provided a significant correlation with the retinal thickness at the central fovea. These results indicate that OCT can facilitate deciding on the treatment protocol (surgical or medical) and follow-up of diabetic patients, which is especially important in the early stages of diabetic maculopathy when the structural changes are not yet evident with slit-lamp biomicroscopy or angiographically.

Dual delivery system for argon laser photocoagulation. Improved techniques of the binocular indirect argon laser photocoagulator.

A dual delivery system provided alternate delivery of the laser beam to the slit lamp and binocular ophthalmoscope. Ophthalmologists may choose between the two systems in accordance with the nature and location of the fundus lesion. A pilot study comparing the rate of laser hit between the slit-lamp photocoagulator and the binocular indirect argon laser photocoagulator (BIALP) showed that accuracy was better with the slit lamp and BIALP when they were operated in the sitting position than with the BIALP operated in the standing position. A photo-electric safety switch was attached to the blocking filter of the BIALP to protect operator's and patient's eyes. The improved machine and techniques increased the efficiency and safety of argon laser photocoagulation. Postoperative use of the BIALP was of particular value. Laser photocoagulation in children's eyes became possible for the first time with the BIALP.

Biochemical changes in selenite cataract model measured by high-resolution MAS H NMR spectroscopy.

PURPOSE: To correlate certain levels of lens opacification with high-resolution magic-angle spinning proton nuclear magnetic resonance (HR-MAS (1)H NMR) spectroscopy analysis of the biochemical changes in rat lenses in a selenite cataract model. METHODS: Selenite cataract was induced by injecting 13-day-old Sprague-Dawley rat pups with a single subcutaneous dose of sodium selenite (3.28 mg/kg in 0.9% sodium chloride solution). Lens opacification was observed using a photographic slit-lamp microscope at selected time-points 3, 6 and 9 days after selenite injection and was then graded (levels 0, 1 and 2). The animals were killed after the slit-lamp microscopy, lenses were removed and HR-MAS (1)H NMR spectra from intact lenses were obtained. Relative changes in metabolite concentrations were determined after comparison with matched lenses from untreated animals. RESULTS: Photographic slit-lamp microscopy revealed different stages of cataract in all animals treated with selenite. In the high quality HR-MAS (1)H NMR spectra of the lenses, more than 30 different metabolites were identified in each lens. With the exception of taurine, the concentrations of all amino acids showed a significant increase (p < 0.05) in the second level of cataract. By contrast, glutathione (GSH), succinate and phosphocholine concentrations were significantly reduced. CONCLUSIONS: For the first time, this study demonstrates the potential to correlate the level of lens opacification with the biochemical changes obtained with HR-MAS (1)H NMR spectroscopy analysis in a selenite cataract model.

The Tajimi Study report 2: prevalence of primary angle closure and secondary glaucoma in a Japanese population.

PURPOSE: To determine the prevalence of primary angle-closure glaucoma (PACG), secondary glaucoma (SG), and all glaucoma in a Japanese population as a part of the Tajimi Study. DESIGN: Population-based epidemiological survey. PARTICIPANTS: A random sample of residents 40 years or older from Tajimi, Japan. INTERVENTION: Each subject underwent a screening program comprising an interview and an ophthalmic examination, including Goldmann applanation tonometry, slit-lamp examination, a van Herick test, fundus photography, and a screening visual field (VF) test using frequency-doubling technology. If glaucoma was suspected, the subject was referred for a definitive examination that included slit-lamp examination, gonioscopy, intraocular pressure measurement, a VF test, and optic disc and fundus examination. A diagnosis of PACG or SG was made based on slit-lamp examination, gonioscopy, optic disc appearance, and perimetric results. MAIN OUTCOME MEASURES: Prevalences of PACG, SG, and all cases of glaucoma. RESULTS: Of 3870 eligible people, 3021 (78.1%) participated in the study. Estimated prevalences of PACG and SG in those over 40 years were 0.6% (95% confidence interval [CI], 0.4%-0.9%) and 0.5% (95% CI, 0.2%-0.7%), respectively. Prevalences of all glaucoma and glaucoma/suspected glaucoma were estimated to be 5.0% (95% CI, 4.2%-5.8%) and 7.5% (95% CI, 6.5%-8.4%), respectively. CONCLUSIONS: Prevalences were 0.6%, 0.5%, and 5.0%, respectively, for PACG, SG, and all glaucoma in subjects over 40 years from Tajimi, Japan.
