Purpose: To report a case of Valsalva retinopathy occurred after sudden crouching to avoid bright light.
Case summary: 48 year old woman was presented with visual decrease in her left eye after sudden crouching to avoid bright light while sleeping. She had no history of systemic or ocular illness. During the initial visit, visual acuity was 2.0 in her right eye and 0.04 in her left eye. Fundus examination revealed a large preretinal hemorrhage extended to the inferotemporal and superotemporal vascular arcade, a 2-disc diameter preretinal hemorrhage on the inferonasal area of retina and optic disc edema and disc hemorrhage. Valsalva retinopathy was suspected due to her history and fundus finding. 2 months after vitrectomy of her left eye, visual acuity improved to 0.6.
