Tobramycin in ophthalmology.

Selman Waksman's laboratory at Rutgers University discovered the first aminoglycoside antibiotic, streptomycin, in 1943. Other aminoglycoside antibiotics, such as gentamicin and tobramycin, soon followed. Tobramycin is compatible with most intravenous fluids and tear substitutes, but it is incompatible with heparin and some beta-lactam antibiotics such as penicillin and cephalosporins. Due to tobramycin's broad spectrum of activity, it has proven useful in controlling both superficial and deep infections of the eye and ocular adnexa (i.e., blepharitis, conjunctivitis, keratitis, and endophthalmitis). However, since tobramycin has been associated with neuromuscular blockade, as well as possessing ototoxic and nephrotoxic effects, care must be taken to minimize toxicity by monitoring patients undergoing systemic tobramycin therapy.

Bilateral lid margin ulcers as the initial manifestation of Crohn disease.

PURPOSE: To report an unusual bilateral ulcerative lid involvement as the presenting manifestation of a severe Crohn disease. DESIGN: Observational case report. METHOD: Description of an otherwise healthy woman who initially presented with bilateral ulcerative lid involvement before the discovery of an extensive ulcerative intestinal inflammatory disease. RESULTS: A 32-year-old woman presented with bilateral ulcerative blepharitis. She also complained of aphthous oral lesions and diarrheic episodes for the previous 3 days. Impression cytology of the lid ulcers showed conjunctival cells, together with the presence of lymphocytes and macrophages. Colonoscopy and colonic biopsy were characteristic of Crohn disease. The treatment with systemic corticosteroids healed bowel, oral, and lid margin ulcerative lesions. CONCLUSION: The simultaneous appearance of ulcerative lesions in the intestinal mucosa and in the mucocutaneous lid margin and the comparable features encountered in the cytologic studies indicate that ulcerative lid margin disease could be an ocular manifestations of Crohn disease.

Eye involvement in inherited epidermolysis bullosa: experience of the National Epidermolysis Bullosa Registry.

PURPOSE: To determine the frequency of ocular manifestations in inherited epidermolysis bullosa (EB) within the continental United States and to define the estimated cumulative risks of developing nonscarring (blisters or erosions) and scarring corneal manifestations within each major EB subtype over time. DESIGN: Observational (cross-sectional and longitudinal). METHODS: Up to 16 years of longitudinal follow-up was conducted on 3,280 consecutively enrolled patients in the National EB Registry, an epidemiologic study funded by the National Institutes of Health. Data were stratified by major EB type and subtype. Frequencies of occurrence were determined for eight variables (corneal erosions or blistering; corneal scarring; symblepharons; blepharitis; ectropions; lacrimal duct obstruction; impaired vision; blindness) by contingency tables, and cumulative risks were generated by life table analysis technique. RESULTS: The most common ocular manifestations were corneal erosions and blisters. Frequencies mirrored relative severity of skin disease, with 74.10% of all patients with recessive dystrophic EB, Hallopeau-Siemens (RDEB-HS) and 47.50% of all patients with junctional EB, Herlitz (JEB-H) experiencing at least one episode. Lower frequencies were noted for corneal scarring. Symblepharons and ectropions were most commonly seen in inversa RDEB and JEB-H, respectively. Blindness was reported in 6.47% of RDEB-HS patients. The cumulative risks of nonscarring and scarring corneal lesions in JEB-H at age 5 are 83.18% and 27.08% and at age 25 are 83.18% and 72.22%. With time, the cumulative risk of each in RDEB-HS approached that reported in JEB-H patients. CONCLUSION: Ocular disease activity, particularly corneal, is common in some EB subtypes. Careful ophthalmologic examination should become an integral part of the management of all patients with inherited EB.

Childhood stye and adult rosacea.

BACKGROUND: Little is known about how individuals with a predisposition for rosacea appear in childhood. This retrospective, matched control, longitudinal study examined the relationship between childhood stye and adult rosacea. METHODS: The records of the Rochester Epidemiology Project were examined to identify patients who received care for stye or blepharitis between ages 2 and 17 years, and received care for any cause at age 40 years or older. Patients were matched by group to control subjects (1:2). RESULTS: Patients with stye during childhood (N = 201) had a higher prevalence of adult rosacea than did control subjects (5.5% vs 1.5%, P = .01). Patients who had other childhood eye conditions without stye (N = 504) were not at higher risk. LIMITATIONS: The study population included few minority patients. CONCLUSIONS: The association between childhood stye and adult rosacea appears to be significant and should be examined further. Rosacea prevalence in adults may be lower (2.1%) than previously reported.

Discoid lupus erythematosus masquerading as chronic blepharoconjunctivitis.

PURPOSE: To recognize discoid lupus erythematosus (DLE) as a treatable cause of chronic blepharoconjunctivitis. DESIGN: Retrospective observational case series. PARTICIPANTS: Records of 5 patients with biopsy-proven DLE were reviewed. METHODS: Clinical and pathology records were examined. MAIN OUTCOME MEASURES: Patients' clinical and histopathological characteristics and response to treatment were assessed. RESULTS: Clinical features included meibomian gland dysfunction, blepharitis, chalazia, trichiasis, madarosis, conjunctivitis, chronic eyelid edema, and eyelid plaques. Histopathology showed hyperkeratotic epithelium, degeneration of the basal cell layer, and a perivascular lymphocytic infiltrate. There was delayed diagnosis in all cases, ranging from 4 months to 25 years. All of the patients responded to systemic hydroxychloroquine therapy. CONCLUSIONS: Heightened awareness of eyelid DLE may lead to earlier detection and specific therapy for this chronic disorder.

Ocular involvement in an outbreak of herpes gladiatorum.

An epidemic of herpes simplex virus type 1 occurred in 60 of 175 wrestlers (34%) attending a four-week intensive training camp. Five of these 60 patients (8%) developed ocular involvement that included follicular conjunctivitis, blepharitis, and phlyctenular disease. Cultures of the conjunctiva and eyelid vesicles were positive for herpes simplex virus type 1 in four of the five patients with ocular disease. The viral isolates were compared by restriction-endonuclease analysis, which disclosed that three of the four isolates were the same strain. None of the patients had corneal involvement and there has been no evidence of viral recurrence to date. Herpes simplex virus type 1 is a health risk for wrestlers, and ocular infections are part of the clinical spectrum. Prompt diagnosis and appropriate management of the outbreak may reduce the severity of the outbreak transmission.

Topically administered norfloxacin compared with topically administered gentamicin for the treatment of external ocular bacterial infections. The Worldwide Norfloxacin Ophthalmic Study Group.

In this double-masked study, we randomly assigned 488 patients with clinical signs of acute bacterial conjunctivitis or blepharitis, or both, to treatment with either norfloxacin ophthalmic solution 0.3% (245) or gentamicin ophthalmic solution 0.3% (243) for one week. Of the patients with positive cultures, 71% (85 of 120) of the norfloxacin-treated patients and 65% (86 of 133) of the gentamicin-treated patients were clinically cured. An additional 25% (30 of 120) of norfloxacin-treated patients and 32% (43 of 133) of gentamicin-treated patients were clinically improved. On the basis of posttreatment cultures, 89% of all cultured bacteria were eradicated (146 of 179 organisms) or suppressed (14 of 179 organisms) after treatment with norfloxacin. The condition of five norfloxacin-treated patients did not clinically improve, compared with the condition of eight gentamicin-treated patients. Both antibiotics had similar efficacy against gram-positive and against gram-negative organisms. One norfloxacin-treated patient and two gentamicin-treated patients withdrew from the study because of local intolerance. Norfloxacin appears to be an effective and relatively safe agent for the treatment of bacterial infections of the eyelids or conjunctiva, or both. In this study, norfloxacin was clinically and microbiologically similar in activity to gentamicin.

The lipid layer of tears: dependent on meibomian gland function.

There is growing laboratory and clinical evidence implicating the meibomian glands of the eyelid as playing a critical role in the pathogenesis of various ocular surface disorders such as chronic blepharitis and dry eye. Meibomian glands produce a lipid material whose synthesis is dependent on factors such as stem cells, neurological stimulants and hormones. This lipid material is fluid, spreads easily, is a surfactant as well as an aqueous barrier, and must remain functional after a blink. Before delivery it can be modified by factors such as hormone abnormalities and even after delivery it may be modified by lipases produced by ocular bacteria.

Phlyctenular eye disease: a reappraisal.

PURPOSE: Phlyctenular keratoconjunctivitis is a nonspecific allergic response in the cornea and/or conjunctiva to a variety of distinct conditions. Tuberculosis as an etiological association is being supplanted by staphylococcal infection and worm infestation in developed countries. Our aim was to determine the relative frequency of the various known etiological factors of phlyctenular keratoconjunctivitis, and the clinical profile of the disease as it exists today in India, a country where tuberculosis is still highly prevalent. CASES: This is a prospective study of 112 consecutive patients with phlyctenular eye disease seen over a 2-year period. OBSERVATIONS: In 86 patients (76.7%), phlyctenular eye disease was associated with tuberculosis. Worm infestation was found in 14 patients (12.4%), whereas 7 (6.2%) had staphylococcal blepharitis. Thirteen patients had evidence of multiple etiology, of which one causative factor was always tuberculosis. When tuberculosis was the only association, 37% patients had severe lesions, whereas only 11. 5% patients without tuberculosis had such lesions. When tuberculosis along with another etiological factor was present, the incidence of severe lesions increased to 84.6%. Recurrence on follow-up was seen in three patients who were already on multidrug therapy for tuberculosis, and two who had tubercular allergy. CONCLUSIONS: Our study shows that tuberculosis is still a major cause of phlyctenular eye disease in India. Severe lesions are more common in patients with tuberculosis, especially when another etiological factor is associated. Recurrences are more common in patients with tuberculosis. Corneal lesions are less extensive than described in the literature and are no longer a significant cause of blindness.

Post kala-azar ocular leishmaniasis.

The clinical features, diagnosis and treatment of 6 patients with post kala-azar ocular leishmaniasis are described. The eye lesions were associated with past or concomitant post kala-azar dermal leishmaniasis (PKDL). Four patients had post kala-azar leishmanial conjunctivitis and blepharitis. Using the polymerase chain reaction, the causative parasite was characterized as Leishmania donovani in 2 of these 4 patients. Two patients had post kala-azar anterior uveitis. The diagnosis of uveitis was based on the clinical manifestations, temporal relation to treated visceral leishmaniasis, the association with PKDL and positive anti-Leishmania serology. All patients were treated with systemic sodium stibogluconate. Patients with anterior uveitis were also treated with steroid and atropine eyedrops. The response to treatment was good. The importance of early diagnosis and treatment of ocular leishmaniasis is stressed.

The ocular surface in cystic fibrosis.

Seventeen patients with cystic fibrosis and 17 age-, race-, and sex-matched controls were examined under standardized conditions. Testing included slit-lamp biomicroscopy, fluorescein staining, rose bengal staining, Schirmer's basic tear test, tear film break-up time, tear pH, tear lysozyme, tear protein, lid and conjunctival cultures, and conjunctival impression cytology. Cystic fibrosis patients showed a statistically significant increase in the incidence of fluorescein staining and clinical blepharitis, as well as significantly decreased Schirmer testing and tear lysozyme. Ocular surface abnormalities in these patients may be attributable to aqueous and lipid tear film deficiencies. Cystic fibrosis patients showed normal conjunctival epithelial cell morphology, grew no pathogenic organisms, and had a decreased incidence of conjunctival bacterial colonization.

Conjunctival cytologic features of primary Sjögren's syndrome.

To determine whether there are specific cytologic features associated with primary Sjögren's syndrome (SS), the authors evaluated impression cytology specimens from three conjunctival sites (temporal bulbar [TB], inferior bulbar [IB], and inferior tarsal [IT]) from 38 SS eyes, 34 eyes of aqueous tear-deficient patients without SS, 35 eyes of seborrheic blepharitis patients, and 17 eyes of normal controls in a masked fashion. The following features were observed more frequently in SS eyes than in the eyes of the other groups: squamous metaplasia of the TB and IB (P less than 0.05), extensive (greater than 75%) goblet cell loss of the TB (P less than 0.05), mucous aggregates of the bulbar conjunctiva (P less than 0.05), and inflammatory cells intercalated with epithelial cells on the IT conjunctiva (P less than 0.06). The conjunctival inflammatory cell infiltrate correlated with the presence of extensive squamous metaplasia (P less than 0.01) in SS specimens. The inflammatory cells on the IT conjunctival epithelium were found to consist predominantly of T-lymphocytes by immunofluorescent staining of cytologic specimens from six eyes. Based on these findings, the authors speculated that conjunctival squamous metaplasia, in addition to aqueous tear deficiency, may be due to primary involvement of the dysfunctional immune system of SS.

The efficacy of topical metronidazole in the treatment of ocular rosacea.

PURPOSE: The purpose of the study is to investigate the efficacy of metronidazole topical gel in the treatment of ocular rosacea. METHODS: Ten patients with ocular rosacea were treated prospectively with lid hygiene and topical metronidazole applied to the lid margin in one eye and lid hygiene alone in the fellow eye. The treatment period was 12 weeks. A masked observer graded the ocular findings at the initial visit and at the conclusion of the treatment period. Pretreatment scores were compared with post-treatment scores with respect to ocular surface, eyelid margin, and combined eyelid plus ocular surface. RESULTS: Eight of ten treated eyes improved, whereas only five of ten control eyes improved. There was a statistically significant improvement in the eyelid score in both the treated and control groups (P = 0.003, P = 0.025, respectively), but no significant improvement in the ocular surface score in either group. When the pretreatment and post-treatment eyelid and ocular surface scores were combined, there was a significant improvement in the treated eyes but not in the control eyes (P = 0.022, P = 0.10, respectively). No adverse effects of the metronidazole treatment were encountered in this study. CONCLUSION: Metronidazole topical gel may be a safe and effective means of treating rosacea blepharitis.

[Phthiriasis pubis palpebrarum in children. Diagnosis and treatment].

INTRODUCTION: Phtiriasis palperarum is an unusual cause of blepharitis. This ectoparasitic infestation of the lashes is more frequent in adult; a pubic attack is usually associated. It is however rare in children. The goal of our study is to bring back four observations of infantile phtiriasis palpebrarum. PATIENTS AND METHODS: Four children presented themselves for palpebral itching and ocular redness. Slit lamp examination revealed evidence of small parasites attached to the proximal extreme of the eyelashes. A survey within the family was carried out and parasitological examination was realized. RESULTS: Parasitological examination had identified adult forms and nits of phtirus pubis. The bed linen was the way of contamination. Mechanical extraction of the parasite was tried but was very painful. Two patients were treated with a regimen of 1% yellow oxide of mercury ointment four times daily for 14 days, the two others was treated by Vaseline pomade because of a very important palpebral irritation. Evolution was favorable among all patients. DISCUSSION: We discuss in this work the ways of contamination of phtiriasis palpebrarum in children. In fact, eyelashes contamination in children is secondary to a contact with an adult carrier of a pubic phtiriasis. The transmission can be done following sexual maltreatments or by the means of infected clothing or bed linen. The diagnosis of phtiriasis palpebrarum is clinical confirmed by parasitological examination. Different therapeutic were proposed, the mechanical treatment must be carried out but it is seldom sufficient and it is often necessary to associate a chemical treatment (malathion to 1%, mercury oxide with 1%, fluorescein with 20%...) or physical treatment (cryotherapy, laser argon). CONCLUSION: Diagnosis of phtiriasis palpebrarum is easy and requires the detection of the source of contamination in order to prevent reinfestations.

Inhibitory function of two NFAT family members in lymphoid homeostasis and Th2 development.

Nuclear factor of activated T cells (NFAT) is a critical regulator of early gene transcription in response to TCR-mediated signals. Here, we show that mice lacking both NFATp and NFAT4 develop a profound lymphoproliferative disorder likely due to a lowered threshold for TCR signaling coupled with increased resistance to apoptosis secondary to defective FasL expression. NFAT mutant mice also have allergic blepharitis, interstitial pneumonitis, and a 10(3) to 10(4) fold increase in serum IgG1 and IgE levels, secondary to a dramatic and selective increase in Th2 cytokines. This phenotype may be ascribed to unopposed occupancy of the IL-4 promoter by NFATc. Our data demonstrate that lymphoid homeostasis and Th2 activation require a critical balance among NFAT family members.
