Posterior Segment Involvement in Childhood Presumed Trematode Induced Granulomatous Anterior Uveitis

Abstract

ABSTRACT Purpose To outline posterior segment characteristics of presumed-trematode induced granulomatous uveitis. Design A cross-sectional case series. Methods The study included 56 patients (60 eyes) presented with anterior chamber (AC) granulomas. Involvement of the posterior segment structures has been documented and reported. Results The mean age of the patients was 11.8 years (range 6–14 years). Posterior segment findings were vitritis in 9 eyes (15%), optic disc granuloma in 2 eyes (3.3%), optic disc hyperaemia in one eye (1.7%), macular oedema in 2 eyes (3.3%), epiretinal membrane in 3 eyes (5%), retinal vasculitis in one eye, a peripheral focus of retinitis in one eye (1.7%), and choroid thickening in 10 eyes (6.7%), with localised choroidal granuloma in one eye (1.7%). Conclusion Presumed trematode-induced anterior chamber (AC) granuloma is not only restricted to the anterior segment of the eye, but posterior segment associations that may threaten vision should also be considered.
