Effect of 2% dorzolamide on retinal blood flow: a study on juvenile primary open-angle glaucoma patients already receiving 0.5% timolol.

AIM: To investigate whether dorzolamide modifies peripapillary retinal haemodynamics in juvenile primary open-angle glaucoma (JPOAG) patients treated with timolol. METHODS: In 40 JPOAG subjects, before and after dorzolamide coadministration with timolol, the following examinations were achieved: intraocular pressure (IOP), blood pressure (BP), ocular perfusion pressure (OPP), heart rate (HR), visual field and retinal flowmetry. RESULTS: Adjunctive therapy with dorzolamide induced the following modifications: IOP reduction [1.75 mmHg, 95% confidence interval (CI) 1.23, 2.26; P < 0.05], OPP increase (5.09 mmHg, 95% CI 2.97, 7.20; P < 0.02) and retinal blood flow improvement (35.0 arbitrary units, 95% CI 12.20, 57.80; P < 0.03). BP, HR and visual field indices did not change. CONCLUSIONS: Dorzolamide, in association or in fixed combination with timolol, significantly improves retinal blood flow in JPOAG patients.

Endogenous Aspergillus versicolor endophthalmitis in an immuno-competent HIV-positive patient.

A 25-year-old white, HIV-positive, immuno-competent man was referred to us because of a progressive blurred vision in his right eye. Clinical characteristics were suggestive for an unilateral fungal endophthalmitis, and thereby fluconazole firstly, followed by conventional amphotericin B were intravenously administered, without any significant improvement. Thus, a pars plana vitrectomy was performed. Aspergillus versicolor was isolated from the cultures of the vitreous sample and intravenous liposomal amphotericin B was administered. An increase of visual acuity together with a reduction of vitreous inflammation occurred. This case of ours represents the first report describing an endogenous endophthalmitis induced by Aspergillus versicolor.

Mesectodermal leiomyoma exclusively involving the posterior choroid.

PURPOSE: To report a mesectodermal leiomyoma of the posterior choroid. DESIGN: Observational case report. METHODS: A 23-year-old man was referred to us because of a progressive blurred vision in his left eye. Ophthalmologic examination revealed the presence of a 12 x 10 x 7.2-mm amelanotic choroidal mass in his left posterior pole. Fluorescein angiography, A-scan ultrasonography, and B-scan echography findings were suggestive for a diagnosis of choroidal amelanotic melanoma. These clinical features prompted us to enucleate the left eye. RESULTS: Histopathological and immunohistochemistry examinations established a definitive diagnosis of mesectodermal leiomyoma of the posterior choroid. CONCLUSION: This case represents the first report describing the occurrence of an intraocular mesectodermal leiomyoma that may exclusively involve the posterior choroid.
