Dry AMD is characterized by deposition of drusen under the retina causing the photoreceptors (light-sensitive cells in the macula) to slowly break down. This will be presented as gradual blurring of central vision in the affected eye. As the disease advances, the patient will have difficulty recognizing faces, and may need more light for reading and other tasks. Dry AMD generally affects both eyes, but vision can be lost in one eye while the other eye still sees well.
