Question

Central retinal vein occlusion (CRVO), a disorder that leads to blindness, is thought to be caused by erythrocytes attaching to the interior lining of the central retinal vein. Erthyrocytes most likely adhere to which structures in patients with CRVO?

A. Smooth muscle cells
B. Platelets
C. Leukocytes
D. Endothelial cells

Answer 1

In Central Retinal Vein Occlusion (CRVO), erythrocytes are likely to adhere to the endothelial cells lining the central retinal vein, potentially contributing to the occlusion. The answer is option D.

Step-by-step explanation:

In patients with Central Retinal Vein Occlusion (CRVO), erythrocytes are most likely to adhere to the endothelial cells that line the interior surface of blood vessels, including the central retinal vein. These endothelial cells are crucial in maintaining the function and integrity of the vessels. CRVO is a disorder that can lead to blindness and occurs when blood and blood components leak out of a severed blood vessel, causing erythrocytes to attach to the endothelial cells.

In cases like CRVO, where there is a disturbance in the normal blood flow, erythrocytes can become attached to these cells, contributing to the occlusion of the vein.
