Keratitis in six dogs after topical treatment with carbonic anhydrase inhibitors for glaucoma.
6 dogs (10 eyes) with keratitis following long-term topical treatment with a carbonic anhydrase inhibitor (CAI) were evaluated. In 4 dogs (6 eyes), CAI treatment was discontinued. Three dogs (4 eyes) underwent enucleation because of end-stage corneal disease. One dog was treated differently in each eye and thus was represented in both aforementioned groups.. Following initiation of treatment with a CAI (ie, brinzolamide or dorzolamide), the median time to development of severe ocular signs was 266 days (range, 133 to 679 days). Clinically severe ocular signs included ulcerative and nonulcerative perilimbal keratitis or severe diffuse keratitis with marked vascularization. The keratitis was refractory to treatment with anti-inflammatory medications. Histologic and immunohistochemical examination of enucleated globes was performed in 3 affected dogs and in 1 dog with keratitis that recovered. Corneal lesions included 2 distinct inflammatory infiltrates with plasma cells predominating in the anterior stroma and both T cells and neutrophils in the epithelium. Stromal plasma cells and overlying epithelium exhibited strong positive immunoreactivity for IgG.. Topical CAI treatment was discontinued in 4 dogs after a median of 209 days (range, 44 to 433 days), and in these dogs, clinical improvement was evident within 2 to 4 days of CAI treatment cessation. Signs of keratitis resolved in 12 to 25 days in these 4 dogs, and median follow-up time after CAI discontinuation was 25.5 months (range, 6 to 42 months), during which time signs of corneal disease did not recur.. On the basis of this small series, presumed topical CAI-associated keratitis in dogs appeared to be an uncommon immune-mediated disease that was not responsive to corticosteroid treatment. Affected patients improved rapidly, but only after discontinuation of CAI treatment. In dogs with glaucoma, clinicians should consider the development of punctate keratopathy and severe diffuse keratitis as potential adverse effects related to topical administration of CAIs, even after previously uneventful long-term use.

[Signs and symptoms of ocular surface disease in patients on topical intraocular pressure-lowering therapy].
To determine the prevalence of signs and symptoms of ocular surface disease (OSD) in patients using topical intraocular pressure-lowering therapy.. In this cross-sectional study, 40 patients were consecutively recruited from the glaucoma clinic of a public hospital located in Rio de Janeiro, Brazil. Eligible patients were 18 years of age or older, with primary open-angle glaucoma or ocular hypertension and on the same topical ocular therapy for at least 6 months. The following data were considered: sex, age, medication history and number of years on topical intraocular pressure-lowering therapy. All patients underwent an evaluation of the ocular surface which included: an interview using the Ocular Surface Disease Index® (OSDI®) questionnaire, break-up time, biomicroscopy, fluorescein corneal staining and rose Bengal ocular surface staining.. The mean OSDI® score was 24.6 ± 20.7. Most patients (67.5%) had an abnormal score on the OSDI® questionnaire. In 25% of patients, the score was consistent with mild symptoms, 12.5% with moderate symptoms and 30% with severe symptoms. Blepharitis and punctate keratitis were diagnosed in 42.5% and 20% of patients respectively. Tear film instability was observed in 75% of patients and ocular surface staining with rose Bengal in 35%. A positive statistically significant correlation (r=0.4; p=0.01) was found between OSDI® scores and the duration of topical intraocular pressure-lowering therapy.. Patients with primary open-angle glaucoma or ocular hypertension on topical intraocular pressure-lowering therapy have high prevalence of OSD. Longer duration since diagnosis is significantly correlated with worsening of OSD symptoms.

Ocular factors relevant to anti-glaucomatous eyedrop-related keratoepitheliopathy.
To evaluate the ocular factors contributing to keratoepitheliopathy in glaucoma patients treated with or without anti-glaucomatous eyedrops, and the influences of each anti-glaucomatous eyedrop to keratoepitheliopathy.. The presence and severity of keratoepitheliopathy was investigated in 193 eyes of 110 glaucoma patients. The ocular factors examined were the status of the lipid layer of the tear fluid as assessed by a specular reflection video-recording system, tear volume assessed by Schirmer's test, and tear film stability assessed by tear break-up time. The influences of combined anti-glaucomatous eyedrops and each anti-glaucomatous eyedrops to keratoepitheliopathy were investigated.. The overall occurrence of superficial punctate keratitis was 29.0%. Superficial punctate keratitis was more frequently observed in patients who used more than two anti-glaucomatous eyedrops (35.9%) than in those who used without (19.7%) and one (30.9%). Results of Schirmer's test and break-up time were worse in patients who used combined medication. The occurrence of superficial punctate keratitis in patients who used timolol (46.2%) was significantly more frequent than in those who used carteolol (4.2%). Severity of superficial punctate keratitis and break-up time in patients who used timolol were significantly worse than in those who used carteolol. There were no differences of keratoepitheliopathy and ocular factors between patients who used latanoprost and unoprostone.. The usage of multiple anti-glaucomatous eyedrops induces keratoepitheliopathy by reducing the tear volume and the tear film stability. Carteolol may be used more safely for corneal epithelium.

Marginal keratitis: an uncommon form of topical dorzolamide allergy.
To report a case of marginal keratitis resulting from topical dorzolamide hypersensitivity.. Case report.. A 68-year-old woman presented with bilateral marginal keratitis 2 weeks after commencing bilateral topical dorzolamide. One week after discontinuation of topical dorzolamide, the patient was asymptomatic with complete resolution of corneal infiltrates.. Topical dorzolamide may cause a hypersensitivity reaction in the form of marginal keratitis. Discontinuation of the offending medication should result in complete resolution.
