A man in his 60s presented with subacute vision loss in his right eye for the prior 3 weeks. His medical history was significant for diabetes without retinopathy and radial keratotomy in both eyes for moderate myopia. The patient had undergone 2 ureterorenoscopies over a 2-week period with laser fragmentation for nephrolithiasis. A ureteral stent was placed followed by systemic ciprofloxacin. The patient's urinary symptoms subsequently improved. In the ensuing days to weeks after these urologic procedures, the patient reported fever, weakness, and decreased appetite, which resolved spontaneously after several days but resulted in persistent weight loss of approximately 15 lb. Three months following this episode, visual symptoms developed.On examination, visual acuity was 20/400 OD and 20/20 OS. Intraocular pressure, pupils, visual fields, and ocular motility were normal. On slitlamp examination of the right eye, trace conjunctival hyperemia was present, the anterior chamber had occasional cells, the lens had mild nuclear/cortical cataract, and the anterior vitreous had 2+ cells. Dilated fundus examination of the right eye showed grade 2 vitreous haze, mild optic disc edema, scattered elevated white chorioretinal lesions-some with mild surrounding intraretinal and subretinal hemorrhage-and a prominent macular lesion (Figure 1). In the left eye, there were 3 small white chorioretinal lesions inferiorly and no other abnormalities.
