The success rate is low, and the complication rate can be quite high, including vitreous haemorrhages and choroid al neovascularization at the anastomosis site. Hemodilution: A few studies have suggested the presence of abnormal blood viscosity in CRVO patients. Uveitis is inflammation and swelling that occurs in the urea. The extent of damage in the back interior portion posterior segment depends on factors such as whether the entire central retinal artery or one of its branches is blocked. B. The most important complication is the development of ocular neovascularization, with neovascular glaucoma as the most dreaded complication. However, our experience and our studies showed that these are very unreliable parameters. From the optic chasm, the nerve signals travel along two optic tracts in the brain and eventually to the occipital cortex, where you process and perceive vision. So the first angiogram Figure 9a would make us believe that we were dealing with a non-ischemic CRVO.
What Is Retinal Vascular Occlusion? The fact that I would like to stress at the outset is that ischemic CRVO is a different, far more serious and potentially blinding disease than non-ischemic CRVO, and it requires wholly different management. A cherry-red spot in macula may be seen, along with cotton-wool spots elsewhere, due to retinal nerve Tiber layer haemorrhages.
