Herein, we report the case of a patient who had granulomatous anterior uveitis, internal ophthalmoplegia, and retinal vasculitis during chickenpox disease. A 9-year-old girl was admitted to our clinic with blurred vision and hyperemia in the right eye. Corrected visual acuity was 20/20 in both eyes. Direct/indirect pupillary reactions were negative in the right eye and pupil was dilated. Biomicroscopic examination revealed middle-sized granulomatous keratic precipitates and a severe anterior chamber reaction. Fundus examination was normal. As there were red papules all over the body she was diagnosed as anterior uveitis secondary to chickenpox and systemic/topical acyclovir, topical steroid, antihistaminic suspension, isolation, and follow-up were recommended. On day 6, anterior chamber inflammation decreased remarkably, whereas a salt-pepper appearance was observed in the retina. On day 10, a perivascular sheathing was observed, which regressed after 1 month, and her medications were slowly tapered and discontinued. Although anterior uveitis is a common finding after chickenpox, the occurrence of three different involvements is very rare.
