[Postoperative proliferative vitreoretinopathy in rhegmatogenous retinal detachment associated with stage B preoperative proliferative vitreoretinopathy: comparative results of trans-scleral retinopexy with diode laser or trans-pupillary retinopexy with argon laser].

PURPOSE: To compare the rate of severe postoperative PVR in primary rhegmatogenous retinal detachments (RD) associated with preoperative grade B PVR and managed either with transpupillary Argon laser photocoagulation or transscleral Diode laser photocoagulation. MATERIAL AND METHODS: We evaluated 72 primary rhegmatogenous retinal detachment associated with preoperative grade B PVR (retinal tears with curled posterior edges), referred before any failed attempt to reattach the retina. Eleven RD were due to giant tear. The retinopexy was performed using transpupillary Argon laser. photocoagulation in 46 eyes, and transscleral Diode laser photocoagulation in 26 eyes. Follow up was 6 to 30 months. Statistical analysis used Chi-square test, and variance analysis. RESULTS: The overall rate of postoperative PVR was 6.9% (5/72 eyes). The rate of postoperative PVR was 6.5% (3/46) in eyes managed with Argon laser photocoagulation and 7.7% (2/26) in eyes managed with Diode laser photocoagulation (p > 0.05). The rate of postoperative PVR in RD due to horseshoe tears was 5.4% (2/37) in eyes managed with Argon laser and 8.3% (2/24) in eyes treated with Diode laser (p > 0.05). The rate of postoperative PVR in giant tear was 11.1% (1/9) in eyes managed with Argon laser photocoagulation and 0% (0/2) in eyes managed with Diode laser photocoagulation (p > 0.05). CONCLUSION: In the present series the rate of postoperative PVR was not influenced by the method of photocoagulation (transpupillary Argon laser or transscleral Diode laser). Therefore each technique can be used as the retinopexy method in primary rhegmatogenous retinal detachment associated with preoperative grade B PVR.

Vitrectomy without scleral buckling for primary rhegmatogenous retinal detachment.

Trans pars plana vitrectomy with air-fluid exchange was performed on 29 selected cases of primary rhegmatogenous retinal detachment in which scleral buckling would be the usual surgical approach. The group contained 20 phakic eyes, two aphakic eyes, and seven pseudophakic eyes; the macula was detached preoperatively in 17 eyes (66%). The reattachment rate after one operation was 79% (23 of 29 eyes); after two operations this increased to 93% (27 of 29 eyes). Visual acuities of 20/50 or better were achieved in 22 of 27 successfully treated cases (81%). Vitrectomy without scleral buckling may allow retinal reattachment with excellent visual results in selected cases of primary rhegmatogenous retinal detachment.

Retinal detachment in eyes undergoing pars plana vitrectomy for removal of retained lens fragments.

PURPOSE: To investigate the incidence and outcomes of retinal detachment (RD) associated with retained lens fragments removed by pars plana vitrectomy (PPV). DESIGN: Retrospective, noncomparative, interventional consecutive case series. PARTICIPANTS: All patients who underwent PPV for retained lens material after cataract surgery at Bascom Palmer Eye Institute between January 1, 1990, and December 31, 2001. METHODS: Demographic and clinical data were extracted from patients' medical records. MAIN OUTCOME MEASURES: Incidence of retinal detachment, reattachment rate, and visual acuity outcome. RESULTS: RD occurred in 44 of 343 (12.8%) patients, including 25 (7.3%) before or during PPV and 19 (5.5%) after PPV. The RD was macula-on in 22 of 44 (50%) patients and macula-off in 22 of 44 (50%) patients. The RD was associated with a giant retinal tear in 7 of 44 (15.9%) patients, limited suprachoroidal hemorrhage in 3 of 44 (6.8%) patients, and endophthalmitis in 4 of 44 (9.1%) patients. Retinal reattachment was achieved in 40 of 44 (90.9%) patients; 14 of 44 (31.8%) patients underwent one or more additional procedures for recurrent detachment. Final visual acuity in the patients in this series was >/=20/40 in 8 of 44 (18%), 20/50 to 20/100 in 13 of 44 (30%), 20/200 to 5/200 in 13 of 44 (30%), and <5/200 in 10 of 44 (23%). In the 36 patients with vision less than 20/40, the primary causes of decreased vision were attributed to prior history of RD in 8 of 36 (22.2%), corneal edema in 7 of 36 (19.4%), cystoid macular edema in 5 of 36 (13.9%), persistent retinal detachment in 4/36 (11.1%), preexisting primary open-angle glaucoma in 4 of 36 (11.1%), age-related macular degeneration in 3 of 36 (8.3%), epiretinal membrane in 2 of 36 (5.5%), macular hole in 1 of 36 (2.7%), optic atrophy in 1 of 36 (2.7%), and irregular astigmatism in 1 of 36 (2.7%) patients. CONCLUSIONS: RD is a frequent complication in eyes undergoing PPV for removal of retained lens fragments. Despite favorable retinal reattachment rates, visual acuity outcomes are often poor in these eyes and are associated with other comorbidities such as corneal edema and cystoid macular edema. Poor initial visual acuity and the presence of a retinal tear at the time of PPV were associated with a higher rate of RD after PPV.

Indirect ophthalmoscope perimetry in patients with retinal detachment or retinoschisis.

PURPOSE/METHODS: We evaluated visual field testing, using indirect ophthalmoscopy, in patients with retinal detachment or retinoschisis. While performing ophthalmoscopy, we projected a shadow onto the schisis or detachment by holding a scleral depressor on the observer's side of the condensing lens. A response was recorded as positive if the patient saw the shadow. RESULTS/CONCLUSION: In all 20 detachment eyes, compared to zero of 12 schisis eyes, the response was positive. Indirect ophthalmoscope perimetry can help distinguish retinoschisis from retinal detachment.

[Pseudophakic retinal detachment is frequently a sequela of surgical complications].

In a retrospective study we analyzed the records of 18 patients with pseudophakic retinal detachment. Cataract operation had been performed by extracapsular (n = 14) and intracapsular procedures (n = 6). In 14 of 18 cases, intra- or postoperative complications preceded the retinal detachment: capsular rupture with vitreous loss and anterior vitrectomy during cataract operation (n = 5), vitreous wick (n = 5), and explantation of the intraocular lens because of chronic intraocular inflammation (n = 3). At the time of admittance for retinal surgery, 14 patients (78%) had a detached macula. In 8 cases (44%), proliferative vitreoretinopathy had developed. In 17 of 18 cases (94%), the retina could be reattached by buckling procedures alone or combined with vitrectomy and SF6 or silicone oil tamponade. The risk of retinal detachment in pseudophakic eyes should be reduced by careful anterior vitrectomy in cases of vitreous prolapse and vitreous wick or by avoiding lens implantation in complicated cataract operations.

Long-term follow-up of retinal detachment due to macular hole in myopic eyes treated by temporary silicone oil tamponade and laser photocoagulation.

PURPOSE: To determine the long-term anatomic and functional results of temporary silicone oil tamponade coupled with laser photocoagulation of the macular hole rim for retinal detachment due to macular hole in eyes with myopia higher than -10.0 diopters (D). DESIGN: Retrospective, noncomparative case series. PARTICIPANTS: Eleven patients (9 female, 2 male; average age, 57+/-3 years) with spontaneous retinal detachment due to macular hole. All patients had a myopia higher than -10.0 D and had no proliferative vitreoretinopathy and no history of trauma. The average myopia amounted to -17.7+/-1.1 D, and in eight cases, a large posterior staphyloma was present. Follow-up was 69+/-17 months. INTERVENTION: Patients underwent pars plana vitrectomy, temporary silicone oil tamponade, and laser photocoagulation of the macular hole rim. Silicone oil removal was performed after 2.8+/-0.8 months. MAIN OUTCOME MEASURES: Anatomic attachment of the retina was determined and visual acuity was measured. RESULTS: Final successful retinal attachment at the end of follow-up was achieved in ten eyes (91 %). Average logarithm of the minimum angle of resolution (logMAR) visual acuity increased from 1.39+/-0.12 before surgery to 1.18+/-0.13 after surgery (P < 0.05, Student's t test for paired data). This corresponds to a mean increase of measured Snellen equivalents from 0.06+/-0.03 to 1.11+/-0.04. Intraocular pressures remained stable with 13.9+/-1.8 millimeters of mercury (mmHg) before surgery and 16.6+/-1.6 mmHg at the end of follow-up (P > 0.05). CONCLUSIONS: Primary vitrectomy with temporary silicone oil tamponade and laser photocoagulation of the macular hole rim for retinal detachment due to macular hole in highly myopic eyes appears to provide a good long-term anatomic success and acceptable functional results.

Vitrectomy for diabetic traction retinal detachment using the multiport illumination system.

OBJECTIVE: To examine the visual and anatomic results of bimanual vitrectomy surgery with the multiport illumination system (MIS) in eyes with advanced diabetic traction retinal detachment. DESIGN: Retrospective, noncomparative interventional case series. PARTICIPANTS: Sixty-seven consecutive eyes in 62 patients having vitrectomy with the MIS. METHODS: During surgery, the vitreous, the posterior hyaloid membrane, and fibrovascular proliferative tissue were removed by using bimanual dissection made possible by the MIS. MAIN OUTCOME MEASURES: Retinal reattachment rate, visual function, and postoperative complications were compared with previously published series of vitrectomy for diabetic traction retinal detachment. RESULTS: With a minimum of 6 months of follow-up, complete retinal reattachment was achieved in 62 eyes (93%), and macular attachment was achieved in all 67 eyes. Vision was stabilized or improved in 51 eyes (72%), and 5/200 vision was achieved in 47 eyes (70%). No unique complications, such as incision-related retinal tears, occurred. CONCLUSION: MIS allows bimanual surgery during vitrectomy for diabetic traction retinal detachment, with good visual and anatomic results.

Pathogenesis of retinal detachment associated with morning glory disc.

Pars plana vitrectomy was performed on a six-year-old boy with complete retinal detachment associated with a morning glory disc of his left eye. Perfluorodecalin was injected to unfold the retina. During surgery, perfluorodecalin leaked repeatedly under the retina. This case demonstrates that a retinal hole in tissues lying within the optic disc anomaly provides a communication for fluid and perfluorodecalin between the subretinal space and vitreous cavity resulting in a rhegmatogenous retinal detachment in the morning glory syndrome.

Schwartz-Matsuo syndrome in retinal detachment with tears of the nonpigmented epithelium of the ciliary body.

PURPOSE: To elucidate clinical features of Schwartz-Matsuo syndrome (photoreceptor outer segment glaucoma) occurring in retinal detachment with tears of the nonpigmented epithelium of the pars plana or plicata of the ciliary body. METHODS: We reviewed retrospectively medical records of 17 consecutive patients (18 eyes) with retinal detachment caused by tears of the nonpigmented epithelium of pars plana (10 eyes) and pars plicata (8 eyes) of the ciliary body. RESULTS: Aqueous cells, ranging from 1+ to 3+, were found in 15 eyes, in contrast with no cells in the other 3 eyes. Eleven of the 15 eyes with aqueous cells showed circadian fluctuation of the intraocular pressure with a range, 4 mmHg or wider compared with the range in the fellow eye, but only 4 of these 11 eyes had a maximum pressure of 21 mmHg or higher. Photoreceptor outer segments were detected in the aqueous humor of 8 eyes out of 14 eyes with aqueous cells in which aqueous tap was done. The remaining 6 eyes had too small a number of aqueous cells for electron microscopy. CONCLUSION: Marked fluctuation of the intraocular pressure compared with the fellow eye, which was not necessarily associated with its rise, was found in retinal detachment with tears of the nonpigmented epithelium of the ciliary body, and should be included as one of key features for diagnosis of Schwartz-Matsuo syndrome.

LASIK after retinal detachment surgery.

PURPOSE: To compare, in the same individuals, the safety and efficacy of laser in situ keratomileusis (LASIK) in eyes with and without previous retinal detachment surgery. METHODS: In a prospective clinical trial, seven myopic patients who had previously undergone scleral buckling surgery in one eye underwent conventional LASIK surgery in both eyes. Uncorrected visual acuity (UCVA), best corrected visual acuity (BCVA), refraction, Orbscan topography and pachymetry were recorded before and 1, 3, 6 and 12 months after surgery. The eyes were divided into two groups: group 1 consisted of eyes that had undergone previous surgery for retinal detachment, and group 2 consisted of the fellow eyes of the same patients, which had not undergone any previous ocular surgery. Student's t-test for match-paired data was used to evaluate the significance of differences. RESULTS: LASIK was performed successfully in all patients. The UCVA improved in all eyes in both groups. The mean change in the spherical equivalent between 1 and 12 months after LASIK surgery was 1.7 +/- 1.1 and 0.6 +/- 0.5 diopter in groups 1 and 2, respectively (p = 0.019). CONCLUSION: LASIK may be considered for treatment of myopia in eyes that have had previous surgery for retinal detachment. However, the risk of regression may be higher in such eyes than in eyes with no previous scleral buckling surgery.

Combined silicone and fluorosilicone oil tamponade (double filling) in the management of complicated retinal detachment.

We evaluated the use of simultaneous double filling with polydimethylsiloxane (PDMS) and fluorosilicone (FSiO) in the repair of complicated retinal detachment in 12 selected cases. Initial retinal reattachment was achieved in all cases. Proliferative vitreoretinopathy (PVR) recurred in 10 patients (83%), 6 of which showed partial retinal detachment. Inferior and superior postoperative residual free spaces were abolished by this procedure, but a new residual fluid space was created, lying horizontally between the bubbles and expanding in a triangular shape nasally to the optic disk and temporally to the macula. Overall, 9 of 10 eyes with postoperative PVR had proliferation involving these areas. These findings support the concept that 'compartmentalization' is of major importance in determining postoperative cell proliferation.

Effects of retinal detachment surgery on protein C antigen level.

BACKGROUND: The purpose of the study was to evaluate perioperative changes in protein C antigen (PC Ag) in patients undergoing retinal detachment surgery under general or local anesthesia. MATERIAL AND METHODS: Prospective study of 39 patients: 27 patients, 14 male, 13 female, age from 15 to 78 (mean: 50.8, SD=18.6), undergoing retinal detachment surgery (encirclement with scleral buckling) performed under general anesthesia (group A), and 12 patients, 5 male, 7 female, age from 25 to 78 (mean: 52.9, SD=19.2), operated under local anesthesia (group B). Patients with venous or arterial disease or other factors which could affect the evaluated parameters were excluded from the study. Blood samples were collected from the cubital vein one day before surgery, immediately after induction of anesthesia but before surgery, immediately after the completion of the operation but before the termination of anesthesia, and after surgery (on the 1st and 4th day). The PC Ag concentration was measured in the citrate plasma of the patients studied, utilizing a commercially available enzyme-linked immunosorbent assay. RESULTS: In both groups, the pattern of changes in perioperative PC antigen was similar. A trend towards moderately lower intraoperative levels of PC Ag could be observed. In both groups, PC Ag concentration increased on the first postoperative day, but a significant change was noted only in general anesthesia group. CONCLUSIONS: Retinal detachment surgery evokes a less than statistically significant decrease in intraoperative PC antigen levels in systemic circulation, and these changes are not affected by the type of anesthesia. An increase in PC Ag was observed on the 1st postoperative day, but this was statistically significant only in the general anesthesia group.

Ocular blood flow parameters in patients with rhegmatogenous retinal detachment.

The aim of the present study is to evaluate the potential statistically significant differences in the ocular blood flow parameters in eyes with rhegmatogenous retinal detachment (RD). Eleven patients, 5 females and 6 males, mean age 46 years (range 22-70), with the unilateral rhegmatogenous RD were enrolled in the study. Colour Doppler Ultrasound was used to measure ocular blood flow velocities in the ophthalmic artery (OA), posterior ciliary's arteries (PCA) and ophthalmic vein (OV). The contralateral eye served as a control. All Doppler examinations were performed 1 day before and exactly 3 days after the retinal detachment surgery. The measurements of the peak systolic velocity (Vmax), diastolic velocity (Vd), minimum velocity (Vmin), time-averaged velocity (TAV), resistive index (RI) and pulsatility index (PI) showed no statistically significant difference (by paired Student's t-test, p > 0.05) between the OA, PCA and OV in healthy eyes and eyes with RD before operation, as well as between the eyes with RD before and after the operation. Only was increased RI in OV of eyes with RD after the surgery (p < 0.05). All these parameters were not related with 2 or more quadrants of RD, but the difference in duration of retinal detachment in days is statistically significant (by Wilcoxon t-test p > 0.05). Pearson correlation method gave statistically significant correlation between RI and PI of the OA in healthy eyes (r = 0.826, p < 0.01), eyes with RD before operation (r = 0.847, p < 0.01) and eyes with RD after the operation (r = 0.856, p < 0.01). Formula for the calculation of PI by RI was derived using linear regression analysis in all three cases. Scleral buckling surgery leaves the ocular blood parameters in OA unchanged. The correlation between RD and logarithm of duration of RD in days is statistically significant.

Results and complications of temporary silicone oil tamponade in patients with complicated retinal detachments.

BACKGROUND: To assess the results and complications of temporary silicone oil tamponade in the treatment of complicated retinal detachments. METHODS: Fifty-eight consecutive eyes undergoing silicone oil removal were studied in a retrospective fashion. Forty-two eyes with proliferative vitreoretinopathy, nine eyes with giant tears, and seven traumatized eyes were included. In addition to anatomic and visual results, the following complications and their associated preoperative and intraoperative variables were assessed: glaucoma, hypotony, and keratopathy. RESULTS: Anatomic success was achieved in 81% of the eyes. Postoperative glaucoma was found in 12%, hypotony in 9%, and keratopathy in 7% of the eyes. Twenty-six (45%) of the 58 eyes had an increase in visual acuity of at least two Snellen lines after silicone oil removal. After multivariate logistic regression analysis for all variables versus the visual and anatomic results and versus the complications of glaucoma, hypotony, and keratopathy successively, a total of three or more operations (P < 0.05; odds ratio, 14.7) and the absence of an encircling band (P < 0.05; odds ratio, 29.9) were associated with redetachment, and a retinectomy size of more than 180 degrees was associated with hypotonia (P < 0.05; odds ratio, 67.5). CONCLUSIONS: Temporary silicone oil tamponade may be associated with a lower incidence of complications than recent studies have reported. Despite the acceptable risk of recurrent retinal detachment, the early removal of silicone oil may yield a lower rate of anterior segment complications and an increase in visual acuity in approximately half the eyes.

Cystoid macular edema, retinal detachment, and glaucoma after Nd:YAG laser posterior capsulotomy.

A series of 897 Nd:YAG laser posterior capsulotomies were reviewed for the complications of cystoid macular edema, retinal detachment, new onset of glaucoma, and worsened preexisting glaucoma. After Nd:YAG capsulotomy, 11 patients (1.23%; 95% confidence interval, 0.51% to 1.95%) developed cystoid macular edema and eight patients (0.89%; 95% confidence interval, 0.28% to 1.5%) developed a retinal detachment. The new onset of glaucoma was observed in seven patients (0.78%; 95% confidence interval, 0.20% to 1.36%). Five patients (0.56%; 95% confidence interval, 0.07% to 1.05%) with preexisting glaucoma had persistent worsening of their glaucoma. Most patients with a complication had no identifiable risk factors in common. The numbers of laser pulses and energy delivered were not risk factors. Retinal detachment and cystoid macular edema developed most often many months after capsulotomy and many months to years after the cataract surgery. Patients undergoing Nd:YAG laser capsulotomy therefore require ongoing medical observation to detect and treat these serious complications.

[Pseudohypopyon of cholesterol crystals occurring 16 years after retinal detachment in x-linked retinoschisis].

BACKGROUND: Cholesterol crystals of the anterior chamber can be found as a marked feature of advanced cholesterosis bulbi; typically following i. o. hemorrhage after severe trauma, retinal detachment or M. Coats. CASE REPORT: A 39-year-old male patient with longstanding (16 years) retinal detachment in his right eye due to x-chromosomal linked retinoschisis presented with a clinical picture of a hypopyon and mature cataract. Ultrasonography showed a retrolental mass. Phacolytic uveitis was suspected and pars plana lentectomy and vitrectomy was performed. Intraoperatively subretinal chrystals could be detected. A specimen of the aqueous humor and subretinal fluid was evaluated biochemically and histologically and revealed cholesterol crystals. CONCLUSIONS: Cholesterosis bulbi may be similar to lentogenic uveitis and should be included in the differential diagnosis of such processes. To our knowledge this is the first case of cholesterol crystals of the anterior chamber sixteen years after retinal detachment in x-linked retinoschisis.

Iris retraction associated with rhegmatogenous retinal detachment syndrome and hypotony. A new explanation.

Eyes with rhegmatogenous retinal detachment can occasionally be seen with hypotony and a peculiar retraction of the peripheral iris. Herein I report the following new observations in this syndrome: (1) seclusion of the pupil, (2) resolution of the retraction configuration after disruption of the seclusion, (3) the initial manifestation as angle closure secondary to iris bombé interchangeable with the iris retraction configuration with the addition (to bombé) and the withdrawal (from retraction) of pharmacologic aqueous suppressants, and (4) the rapid cataract formation. The theory that vitreous traction or retraction is the cause of the retrodisplacement of the iris was disproved. A hydrodynamic theory is presented. A lowering of pressure behind the iris, at least partially, due to posterior removal of fluid, presumably from the subretinal space, was shown to be the cause of the iris retraction. The iris retrodisplacement occurred when posterior aqueous removal exceeded aqueous formation. This removal of fluid may be an important factor in the understanding of proliferative vitreoretinopathy as the fluid flow involved may draw cells posteriorly.
