What causes retinal cotton wool spots?

Cotton wool spots are an abnormal finding on funduscopic exam of the retina of the eye. They appear as fluffy white patches on the retina. They are caused by damage to nerve fibers and are a result of accumulations of axoplasmic material within the nerve fiber layer.

Can CMV retinitis be cured?

The anti-viral drugs commonly used to treat CMV retinitis are ganciclovir (Cytovene), foscarnet (Foscavir) and cidofovir (Vistide). They can slow down the progression of CMV, but they can’t cure it. Like many drugs, these treatments can cause unpleasant or serious side effects.

Are cotton wool spots serious?

How do cotton wool spots develop?

Is CMV retinitis reversible?

How are cotton wool spots treated in the retina?

Lipohyaline material was building up in the vessel walls and occluding them. Shakib and Ashton 9 reported on an experimental model of ischemia using microsphere embolization of small retinal arterioles. Using electron microscopy, they showed nerve fiber swelling within 1 hour of embolization. Histology revealed three distinct zones in each lesion.

What to do for cytomegalovirus ( CMV ) retinitis?

Cytomegalovirus (CMV) Retinitis. The patient was treated with intravitreal foscarnet in the left eye, and five days of intravenous ganciclovir while as an inpatient for other systemic manifestations. He was discharged on oral valganciclovir (induction dose 900 mg BID for two weeks) then 900 mg daily maintenance until CD4 count was above 50.
