  • Look Inside

We performed light and electron microscopic studies on 2 eyes with rubeotic glaucoma secondary to central retinal artery occlusion. The eyes had to be removed from a 78-year-old female and a 70 -year-old male to relieve ocular pain.

We observed thrombus formation in the lumen of the central retinal artery in the laminal portion of the optic nerve. In the first case, the thrombus was mainly composed of proliferated endothelial cells, smooth muscle cells and collagen fibers. Recanal-ization of the central retinal artery took place in the thrombus. In the second case, the lumen of the central retinal artery was filled with degenerated erythrocytes at the lamina cribrosa. Where the endothelial cells of the central retinal artery had disappeared, platelets and fibrin strands were seen on the basement membrane-like material of the vessel wall by electron microscopy. Beside the ordinary lumen of the central retinal artery, there was a small lumen lined by endothelial cells with abundant intracellular organellae.

We concluded that the central retinal artery occlusion in these cases was caused by thrombus formation at the level of lamina cribrosa.
