Boeck's sarcoid was described by Longcope and Pierson1 as "a chronic infectious granuloma, persisting often for years, sometimes spreading slowly from one organ or tissue of the body to another, frequently relapsing, seldom producing serious constitutional symptoms, resistant to treatment, but at times healing spontaneously." The most frequent site of ocular involvement is the iris. Blegvad2 stated that iritis occurs in 10 per cent of the cases.

The lacrimal gland and the conjunctiva are involved infrequently. The most uncommon sites of sarcoid infiltration are the choroid and the retina. King4 stated that sarcoid must be considered as an extremely rare cause of localized chorioretinitis, an assertion which is definitely borne out by
