Dilated fundus photos in patient with Purtscher-like retinopathy. A 19-year-old diabetic male presented with decreased vision in both eyes for 1 week with no inciting trauma and was found to have a genetic 17q12 deletion associated with mature-onset diabetes of the young 5. A Diabetic retinal screening 3 months prior to initial presentation showed no evidence of diabetic retinopathy. Best corrected visual acuity was 20/20 bilaterally at this time. B Dilated fundus photos 2 weeks after onset of acute painless vision loss revealed multiple cotton wool spots and intraretinal hemorrhages predominantly in the peripapillary region, consistent with Purtscher-like retinopathy. There were no other signs of diabetic retinopathy beyond the peripapillary region in the posterior pole. Visual acuity was significantly decreased compared with 20/200 bilaterally. C One month after presentation, fundus examination showed persistent peripapillary cotton wool spots bilaterally, and visual acuity remained poor bilaterally
