Posterior Segment Involvement in Childhood Presumed Trematode Induced Granulomatous Anterior Uveitis.

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.
