Methods: A total of 50 patients (100 eyes) scheduled for fundoscopy were dilated with phenylephrine 10% and yropicamide 1% (group 0: n = 20 type 2 diabetic patients, 40 eyes, and group 1: n = 30 non-diabetic patients, 60 eyes). Only one drop per eye of each drug was administered.

Flecked retina in systemic large-cell non-Hodgkin's lymphoma: case report.

We report on a patient with a past medical history of successfully treated systemic large-cell non-Hodgkin's lymphoma (SNHL), who presented with multifocal yellowish retinal infiltrates (flecked retina) involving the post-equatorial retina of one eye. Fluorescein angiography revealed that the retinal infiltrates were hypofluorescent throughout the examination. The correct diagnosis of this ocular picture was important because the retinal lesions indicated central nervous system recurrence of systemic large-cell non-Hodgkin's lymphoma.

Subretinal neovascularization following ruptured retinal arterial macroaneurysm: case report.

A 51-year-old black woman was referred to our Retina Clinic for evaluation of loss of vision in her left eye. She was previously diagnosed with a ruptured retinal arterial macroaneurism (RAM) in the same eye. The ophthalmoscopic examination of the affected eye disclosed a subretinal lesion with some hemorrhage and exudation in the same area previously diagnosed with ruptured RAM.

[Cataract extraction using the phacoemulsification technique in patients with uveitis].

Purpose: To report outcomes of cataract extraction by phacoemulsification in patients with uveitis.

Methods: We retrospectively reviewed the charts of 189 patients (242 eyes) with uveitis who underwent cataract extraction by phacoemulsification at the Uveitis and Ocular Immunology Unit of McGill University Health Centre, Montreal, Quebec, Canada.

Results: Average follow-up was 46 +/- 31.

The white dot syndromes.

Several entities must be considered when a patient presents with a white dot syndrome. In most cases these can be distinguished from one another based on the appearance or distribution of the lesions, the clinical course, or patient variables such as age, sex, laterality, and functional and image examinations. In this paper we review the distinctive and shared features of the white dot syndromes, highlighting the clinical findings, diagnostic test results, proposed etiologies, treatment, and prognosis.

Cyclooxygenase-2 expression in human irradiated uveal melanomas.

Aim: Previous studies have shown that radiotherapy is a stimulus for cyclooxygenase-2 (COX-2) expression and that use of COX-2 inhibitors enhances the radio sensitivity of tumor cells. The objective of this study was to evaluate COX-2 expression, and its correlation with tumor regrowth after irradiation, in enucleated eyes with uveal melanomas.

Methods: Fifteen tissue samples from patients who underwent enucleation after radiotherapy between 1988 and 2001 were used.

The expression of cyclooxygenase 2 in retinoblastoma: primary enucleated eyes and enucleation after conservative treatment.

[Choroidal neovascularization associated with sympathetic ophthalmia: case report].

A 7-year-old boy with sympathetic ophthalmia secondary to penetrating ocular trauma developed choroidal neovascularization in the macular region of the sympathizing eye. Posterior segment biomicroscopy disclosed a single, round, small, slightly elevated yellow-white lesion temporal to the fovea, linked to the temporal edge of the optic disc by a fibrotic band. On fluorescein angiography the round lesion showed a gradual hyperfluorescence, with late staining and leakage, and was interpreted as a fibrovascular scar from previous choroidal neovascularization.
