Symptoms

Rarely symptomatic (focal scotomata and decreased contrast).

Signs

Cotton–wool spots, intraretinal hemorrhages, and microaneurysms. An ischemic maculopathy may occur with significant visual loss in 3% of affected patients.

Work Up

Workup

HIV retinopathy is a marker of low CD4+ counts. Look for concomitant opportunistic infections (see 12.9, CYTOMEGALOVIRUS RETINITIS). Rule out the other causes for unexplained cotton–wool spots (see 11.5, COTTON–WOOL SPOT).

Treatment

No specific ocular treatment is necessary, but the retinopathy resolves with cART and increased CD4+ counts.

Follow Up

Patients with CD4+ counts <50 should be examined every 3 to 4 months.

Noninfectious retinopathy is the most common ocular manifestation of HIV/AIDS. About 50% to 70% of patients with AIDS have this condition.
