What are the two main types of Age-related Macular Degeneration?

Age-related Macular Degeneration (AMD) is primarily classified into two main types: dry AMD and wet AMD. Dry AMD is characterized by the gradual accumulation of drusen, which are small yellow deposits under the retina, leading to gradual vision loss. It is the more common form, accounting for approximately 80-90% of cases.

Wet AMD, on the other hand, involves the growth of abnormal blood vessels (choroidal neovascularization) underneath the retina, which can leak fluid or blood and lead to more rapid and severe vision loss. This form is often more serious and requires prompt treatment to prevent significant vision impairment.

Recognizing these two distinct types of AMD is crucial for appropriate diagnosis and management. Other options like stable and unstable, acute and chronic, or reversible and irreversible do not accurately describe classifications of AMD and do not address the specific pathological processes involved in the disease.
