MULTIFOCAL CHOROIDITIS

This typically affects people in their 20's or 30's. The patient presents with blurred vision, floaters, or flashes of light.

There may be anterior uveitis w/ vitreous cells. Fundus examination reveals multiple yellow lesions at the posterior pole and periphery, arranged in clumps or linear streaks (Schlagel lines). 40% of these patients have CME. The borders can become pigmented. There may be visual field defects and enlarged blind spot.

Sarcoid and PIC show similar fundus lesions. Sarcoid lesions are usualy more numerous in the inferior fundus. PIC does not have intraocular inflammation.

Treatment is with systemic and periocular steroids. The disesae is recurrent and chronic and the prognosis is variable from good to poor.
