CENTRAL RETINAL VEIN OCCLUSION (ISCHEMIC in the first picture, NON-ISCHEMIC in the second picture) ⁣

CRVO occurs due to the occlusion of the central retinal vein at or posterior to the lamina cribrosa. It causes painless unilateral loss of vision. ⁣

Pathogenesis : VIRCHOW’S TRIAD : Vessel damage, Stasis and Hypercoagulability. ⁣

The central retinal vein and artery share a common adventitial sheath at arteriovenous crossings posterior to the lamina cribrosa.  Atheroscleortic changes of the artery may compress the vein and cause CRVO. ⁣

Some risk factors include diabetes, hypertension, hyperlipidemia, raised intraocular pressure, hypercoagulable states etc. ⁣

It is important to distinguish between ISCHEMIC vs NON-ISCHEMIC CRVO
