Characteristics of Childhood Presumed Trematode-Induced Granulomatous Anterior Uveitis Using Ultrasound Biomicroscopy.

Purpose: To investigate the UBM characteristics of presumed trematode-induced granulomatous uveitis.Design: Prospective case series.Methods: Thirty patients who presented with anterior chamber (AC) granuloma were included. UBM Imaging included Cornea, iris, AC angle, posterior chamber, ciliary body, and vitreous base.Results: Thirty eyes were included with a mean age of 12.4 ± 2.5 years. UBM findings were retrocrneal membrane (33%), sub conjunctival nodule (10%), AC granuloma (100%); peripheral anterior synechia, granuloma-like lesion in posterior chamber; ciliary body edema with localized granuloma at specific site (100%), cataract in 30% either localized or generalized, and dot or thread-like high reflection on vitreous base in (20%).Conclusion: Presumed trematode-induced AC granuloma is common among children living in the rural areas of Egypt. UBM examinations can demonstrate various pathologic changes of anterior segment of the eye and provide objective evidence for the exact origin of those granulomas.
