Clinical findings:
(1) bilateral decreased visual acuity
(2) often a poor response to oral steroids
(3) often reversible with time unless serious complications occur
Ocular findings are bilateral:
(1) posterior retinal vasculitis
(2) retinitis
Features of vasculitis:
(1) vascular occlusion with decreased perfusion, often with ischemia
(2) macroaneurysms of the retinal arteries
Features of retinitis:
(1) edema (optic disc, other)
(2) exudative maculopathy
Diagnosis requires exclusion of other causes of vasculitis and neuroretinitis.
Complications:
(1) vitreous hemorrhage
(2) traction-type retinal detachment
