Granuloma-like formation in deeper retinal plexus in ocular sarcoidosis.

Sarcoidosis is a multi-system disease characterized by the presence of non-caseating epithelioid granulomas in affected tissues and the most frequent cause of noninfectious uveitis in Japan. Ocular manifestations of sarcoid uveitis vary enormously and commonly characterized by granulomatous anterior uveitis, intermediate uveitis, and posterior uveitis such as retinal periphlebitis, choroiditis, optic nerve granuloma and papillitis. However, case reports of multiple granuloma formation related to sarcoid uveitis is uncommon. This report describes the use of optical coherence tomography angiography to visualize changes occurring in granuloma formation in deeper retinal plexus before and after systemic corticosteroid treatment.
