Objectives: Determine if retrobulbar optic nerve horizontal diameter measurement or reflectivity correlates with the optic disc excavation diameter relation in glaucoma, considering: measurements correlation, the sensitivity and specificity between the methods and which value has greater sensitivity and specificity to differentiate patients with and without glaucoma. Methods: In a masked study, the optic nerves of 38 patients with open angle primary angle glaucoma and 37 control patients were examined for retrobulbar echographic determination of their A mode (DNA) and their […]

Objective: To determine the influence of visual field results in the diagnosis of glaucoma. Methods: A questionnaire with ophthalmologists was conducted where slides of a digital photograph of the optic disc and computerized visual field exam were presented.(Physicians were instructed to answer whether glaucoma was observed in each of the slides). No other information was given to those examiners. Half of the patients had glaucoma with corresponding visual field, and the other half had physiological cupping and normal visual field. […]

Extraintestinal manifestations of Crohn’s disease are common. Although ocular complications of Crohn’s disease are infrequent, most ocular manifestations include iritis, uveitis, episcleritis, scleritis and conjuntivitis. We report a patient who developed uveitis two years before diagnose of Crohn’s disease.

Melanocytoma of the optic disc is a well known variant of melanocytic nevus that usually occurs as a deeply pigmented lesion on the head of the optic disc. Historically, this tumor has often been confused with malignant melanoma. Histopathologically, it is composed of deeply pigmented round oval cells with abundant cytoplasm and small, round, bland nuclei. Melanocytomas is a benign, stationary tumors, with almost no propensity to undergo malignant transformation. Most cases that occur on the optic disc are visually […]

To describe the diagnosis and management of a optic disc haemorrhage probably caused by an acute and spontaneous posterior vitreous detachment. A single case-report of an optic disc haemorrhage probably caused by an spontaneous posterior vitreous detachment, in order to discuss the diagnosis, management and prognosis. Optic disc haemorrhage regression was observed after 6 hours of evolution without relapsing signals during the subsequent registers. The Scanning Laser Ophthalmoscopy revealed as an advanced alternative and efficient method in the vitreous detachment […]
