Report of a Case.  A 33-year-old patient with a complaint of mild visual loss in his right eye was seen several weeks after a flulike illness. His ocular history revealed a similar episode in his left eye 10 years earlier in which he had multiple cotton-wool spots (CWS), received treatment with oral steroids, and recovered promptly. No systemic disease was identified then.Visual acuity was 20/20 OU with myopic correction. The anterior segment examination results and intraocular pressure were normal in both eyes. Fundus examination of the right eye revealed multiple CWS in the posterior pole (Figure 1). A flame-shaped hemorrhage was observed adjacent to the optic disc. There was no vitreous inflammation. Fundus examination of the left eye revealed 3 distinct prepapillary vascular loops (Figure 2). No CWS were observed.Systemic investigation including full hematological workup, ultrasonography of the carotid arteries, and neurological examination results were all within normal
