What does the Beckman Grading System classify as advanced dry AMD?

The Beckman Grading System specifically classifies geographic atrophy as advanced dry age-related macular degeneration (AMD). Geographic atrophy refers to a defined area of retinal pigment epithelium (RPE) loss that leads to photoreceptor degeneration, ultimately resulting in vision impairment. This condition represents the end stage of dry AMD, where there is significant loss of retinal structure and function.

The significance of identifying geographic atrophy lies in its association with the progression of AMD and the potential for visual loss. Recognizing geographic atrophy as a key indicator helps in monitoring the disease's progression and determining appropriate management strategies. Other options, while related to changes in the retina, do not specifically signify advanced dry AMD according to the Beckman Grading System.
