Hypertensive Retinopathy, Intra Retinal Hemorrhage (#3,1) Comment: Sharply defined hemorrhage underneath the internal limiting membrane. (Note the reflexes). Little globs of blood are seen where the blood is located when the patient is in prone position. The prominent white circumferential line may represent the edge of vitreous detachment. Proteinaceous material is deposited in the retina outside this ring. This photo was taken when the patient was lying on his right side to show the mobility of the blood; the disc is above.
Hypertensive Retinopathy (#1,2), Cotton-Wool Spot, Histology Comment: The histological cytoid body corresponds to the clinical cotton-wool spot. It is composed of swollen axons of the nerve fiber layer of the retina caused by closure of small vessels.
