Modified Bagolini striated glass test: clinical applications of starlight test in binocular visual field screening.
AIM To introduce the "starlight" test which was devised to check binocular vision in normal conditions of seeing in a rapid, easy, and cost effective manner and to estimate the possibility of its clinical use in screening the binocular visual field of patients. METHOD The Bagolini striated glass test consists of optically plano lenses with imperceptible parallel scratches that barely blur the...
متن کاملDiagnostic accuracy of confrontation visual field tests.
OBJECTIVE To determine the diagnostic accuracy of confrontation visual field testing and to compare the accuracy of confrontation tests both individually and in combination. METHODS Patients were prospectively recruited from ophthalmology clinics over a 6-month period. All patients underwent SITA-standard 24-2 Humphrey visual field analysis. Two examiners, masked to the automated perimetry re...
متن کاملoccipital war trauma and visual field defects
seven cases of visual field defects, caused by wartrauma were seen at farabi eye hospital. none were referred by a neurologist. four patients had 20/20 visions with normal fundi. one had 12/20, in both eyes, with normal fundi. two patients presented fundus changes. the visual field defects were seen in all these seven patients. four had homonymous hemianopia, one had bilateral field restriction...
متن کاملVisual field defects and neural losses from experimental glaucoma.
Glaucoma is a relatively common disease in which the death of retinal ganglion cells causes a progressive loss of sight, often leading to blindness. Typically, the degree of a patient's visual dysfunction is assessed by clinical perimetry, involving subjective measurements of light-sense thresholds across the visual field, but the relationship between visual and neural losses is inexact. Theref...
متن کاملGanglion cell losses underlying visual field defects from experimental glaucoma.
PURPOSE To investigate the relationship between ganglion cell losses and visual field defects caused by glaucoma. METHODS Behavioral perimetry and histology data were obtained from 10 rhesus monkeys with unilateral experimental glaucoma that was induced by argon laser treatments to their trabecular meshwork. After significant visual field defects had developed, the retinas were collected for ...
