Venous collateral remodeling in a patient with posttraumatic glaucoma.

Abstract

To photographically document venous collateral development, remodeling, and regression in a patient with traumatic glaucoma. Consecutive fundus photographs were evaluated, labeled, and correlated with the clinical history of a patient with unilateral posttraumatic glaucoma. This report photographically documents the appearance, remodeling, and subsequent disappearance of collateral vessels from venous occlusion on the surface of the optic disk in an eye with increased intraocular pressure and progressive glaucomatous cupping. Asymptomatic chronic obstruction of a branch retinal vein on the optic disk may cause venous collaterals to develop in the absence of retinal hemorrhages or other signs of venous occlusive disease. Increased intraocular pressure, arteriolarsclerosis, and glaucomatous cupping are risk factors for these occlusions.
