Dry age-related macular degeneration with unilateral geographic atrophy

Doi: 10.36351/pjo.v41i1.1869

Abstract

An advanced form of age-related macular degeneration (AMD) known as geographic atrophy (GA) is typified by atrophic lesions that begin in the outer retina and gradually enlarge, ultimately resulting in irreversible visual loss. We present the case of a 55-year-old male healthy patient who had dry AMD in one eye and unilateral geographic atrophy in the other eye. Clinical examination, optical coherence tomography (OCT), and OCT angiography were used to confirm the diagnosis. Growing older and family history are the two main risk factors for GA.  Geographic atrophy can be prevented by managing modifiable risk factors such as smoking, controlling systemic disorders, and maintaining a balanced diet.
