Purpose. To compare optic disc topography performed by confocal laser ophthalmoscopy in eyes with nonarteritic anterior ischemic optic neuropathy (NAION), arteritic anterior ischemic optic neuropathy (AAION), and open-angle glaucoma (OAG), adjusting for the amount of retinal ganglion cell (RGC) loss, as measured by nerve fiber layer (NFL) thickness and average visual field loss. Methods. At fou...

PURPOSE To evaluate which morphologic features of the optic disc are predictive factors for the development or progression of visual field loss in chronic open-angle glaucoma. METHODS The prospective observational clinical study included 763 eyes of 416 white subjects with ocular hypertension and chronic open-angle glaucoma. During the follow-up time (mean, 67.4 months; median, 65.1; range, 6...

INTRODUCTION We present a case of a man with optic disc pit maculopathy, whose vision improved after vitrectomy combined with glial tissue removal from the optic pit area, and without the use of photocoagulation. CASE PRESENTATION A 45-year-old man complained of blurred vision, and ophthalmoscopy revealed a retinal detachment and retinoschisis extending from an optic disc pit through the macu...

Optic disc drusen are congenital and developmental anomalies of the optic nerve head seen commonly in clinical practice, often as an incidental ophthalmologic finding during routine exams. Optic disc drusen are a form of calcific degeneration in some of the axons of the optic nerve. Visual acuity is often not affected but the visual fields of these patients can be abnormal and deteriorate over ...

The Valsalva maneuver (VM) is performed frequently in daily activities. It causes various transient physiological changes, including elevated blood pressure, increased intrathoracic pressure, increased peripheral venous pressure stimulation of the peripheral sympathetic system, and increased intraocular pressure (IOP). The mechanism for the transient increase in IOP during VM has not been compl...

Objective: The 97.5th percentile for vertical cup to disc ratio (VCDR) has been proposed as a useful tool to assist in the diagnosis of glaucoma in population studies. Previous reports of VCDR percentiles have either not been adjusted for disc size or have been calculated by regression analysis from small hospital based cohorts. The authors’ aim was to generate VCDR percentiles in a large, popu...

OBJECTIVE To describe subretinal migration of gas and silicone oil in a series of patients with congenital cavitary optic disc anomalies and to further clarify the pathogenesis of the associated maculopathy. METHODS Medical records of 4 female patients, aged 8 to 34 years, who developed subretinal gas migration after vitreous surgery for macular detachment associated with cavitary optic disc ...

Glaucoma is a chronic eye disease in which the optic nerve is progressively damaged. It is the second leading cause of blindness and is predicted to affect around 80 million people by 2020. Development of the disease leads to loss of vision which occurs gradually over a long period of time. Since it is very difficult to cure the disease at severe stage, it can be detected initially by using pro...
