Both right and left eyes have symmetrical ring of mottled hypo/hyper AF around the fovea and disc. The HyperAF areas correspond to RPE deposits on OCT as well as areas of blockage on FA, and drusenoid deposits seen on fundus photos. Disc drusen in right eye present as HyperAF spot 57 yo WF referred for AMD vs Pattern Dystrophy that was diagnosed 10 years ago. Reported some slow progressive vision loss in both eyes for distance and near. Denies nyctalopia or hemeralopia. Background medical history includes HTN, CVD, and DM. No family history of eye problems. Denied pentosan use. Anterior segment showed moderate cataracts (OD>OS). Posterior segment exam showed macular changes and mild NPDR.

Fundus Photos, AF, OCT were performed as well as a gene test. Further questioning showed revealed that her mother and maternal grandmother had both diabetes mellitus and sensorineural hearing loss. The patient developed diabetes in her teens, and some high frequency hearing loss in her early twenties. She had not had a previous genetic test or diagnosis of MIDD. Gene testing is pending for the mitochondrial component. Invitae's retinal panel, which does not include mitochondrial disorders, only showed a variant of uncertain significance, HMCN1. I discussed this case with Dr. Freund, and it is similar to a the case report : Inoue M, Kiss S, Freund KB.
