73-year-old man with 6 weeks of progressively worsening central vision

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.
