The image is consistent with a diagnosis of dry age-related macular degeneration (AMD):
- AMD is the leading cause of irreversible central vision loss among people 50 years and older.
- Dry AMD is the most common type (80% of patients) and is a chronic, slowly progressive disease. It involves subretinal drusen deposits, geographic atrophy of the retinal pigment epithelium, and macular thinning.
- Wet AMD is less common and can develop acutely, resulting in sudden-onset vision loss. It involves abnormal blood vessel growth under the retina. These abnormal vessels may leak, leading to fluid and blood beneath the retina.
