Macular hemorrhage after roller coaster riding in a single-eyed patient with congenital glaucoma

A 21-year-old female presented with a 4-day history of decreased vision in her only functional eye (right eye, OD). She had a history of multiple ocular surgeries in both eyes because of congenital glaucoma and had lost light perception in her left eye several years prior. Ophthalmological examination revealed 0.15 Snellen visual acuity, and fundoscopy revealed nearly total cupping and pallor of the optic disc and multiple retinal hemorrhagic foci in the macula in OD. Lesions spontaneously resolved over a few months. Gravitational forces during a roller coaster ride may have caused this macular hemorrhage.
