Nonarteritic Ischemic Optic Neuropathy with subretinal fluid

These images are of a 56 year old male patient diagnosed with nonarteritic ischemic optic neuropathy in the right eye. The visual acuity was 20/32 and there was a relative afferent papillary defect on the right. The yellow arrows show the difference in presentation of a healthy optic nerve (OS), and the diseased optic nerve (OD). Note that the OD optic disc has a neuroretinal rim that is not clearly defined due to swelling. Occasionally there is peripapillary edema (white arrows) and subretinal fluid (pink arrow). There is an inferior altitudinal visual field defect in the right eye.
