Contributor: Marko Tien (University of British Columbia Medical Student) 

Patient Presentation: A 67-year-old woman was referred to ophthalmology for AMD screening. She has no ocular complaints. No other neurological symptoms. She has a history of hypertension and hypercholesterolemia, for which she is taking medications for. On presentation, visual acuity was 20/25 OU.

Learning Objectives:

  1. To identify reticular pseudodrusen on OCT and fundus photos

  2. To understand how reticular pseudodrusens differ from typical drusens

  3. To understand the prognostic value and association of reticular pseudodrusens with late AMD
