Normal Structure and Histopathology of the Choroidal Vascular System

Abstract
|
|
|
The choroidal vascular system in human eyes has been studied in flat preparation to elucidate the choroidal circultion, particularly choriocapillaris in normal and disease.
The histopathologic studies were performed in views of vascular interconnection, regional differences, choriocapillaris pattern, and drusen and hole in Bruch´s membrane.
The interarterial and intervenous communications are demonstrated. The short posterior ciliary artery angulates around the disc margin and makes an anastomosis between surrounding short posterior ciliary artery. The segment of the choriocapillaris is supplied by a central terminal arterioles and drained by a venule at its margin.
The thickened cuticular layer of Bruch´s membrane may be associated with sclerosis .of the choriocapillaris. Holes in the Bruch´s membrane may contribute to invasion of the choroidal vessel into the subretinal space -leading to subretinal neovascularization.
