Purpose: To report a case of bilateral retinal detachment in a 15-year-old child with Tourette syndrome. Case summary: A 15-year-old child treated for Tourette syndrome for 4 years presented with decreased visual acuity of several days in duration. The fundus of the right eye was not observed due to lens opacity and posterior synechiae. The B-scan of the right eye showed funnel-shaped densely reflective echoes connected to the optic disc, suggesting a total retinal detachment. Fundus examination of the left eye revealed an inverted retinal flap, which covered the posterior pole. During vitrectomy of the left eye, a ciliary body detachment anterior to a giant retinal tear extending 360 degrees was observed. In addition, an inverted flap covering 2 superior retinal quadrants was observed. A perfluorocarbon liquid was injected to unfold the tear’s inverted flap, and silicone oil tamponade was performed. Conclusions: Self-induced and repeated periocular trauma induced by motor tics of Tourette syndrome can result in bilateral retinal detachment. Regular ophthalmic examinations are helpful for early detection of ocular complications including periocular trauma induced by motor tics of Tourette syndrome.
