Abstract

The authors observed retinal vascular patterns of the blind eyes surgically removed on account of pain, high intraocular pressure and global rupture by injury. Material for the study was 10 eyes which were 4 eyes of long standing absolute glaucoma, late stage of chronic simple glaucoma (3 eyes) and chronic angle closure glaucoma (1 eye). aphakic glaucoma (1 eye) and an eye of chronic simple glaucoma with traumatic global rupture. The technique of preparation of the slides was made of flat preparations of retinal vessels that all nonvascular components were digested with tris-buffered 3% trypsin solution and stained with PAS-hematoxylin and Wilder's reticulin stain.
RESULTS
OBTAINED AS FOLLOWS; 1. it is possible that diffuse acellularity (predominant loss of endothelium) in the capillaries of the equatorial and posterior portion of retina results from the arterial occlusion. 2. Solitary microaneurysm in the peripheral retinal capillary was found in the early stage and numerous saccular and fusiform aneurysms (rows of bead-like aneurysms) on the venules, and arteriolar and venular capillaries are related to the degree and duration of the venous occlusion. 3. The majority have had venous occlusion initially, on which distal venule there are found rows of bead-like outpouchings, and the occlusive arterioles show fibrinous appearence, accllularity and increasing PAS staining. 4. It is possible that abnormal A-V shunts and venous collaterals result from the venous occlusion and rows of bead-like microaneuysms in the capillaries will be switched over to shunts and collaterals.
