Drusen are yellowish white deposits that build up beneath the retina. They are a normal result of aging but can also occur with eye disease, such as age-related macular degeneration (AMD).
In people who have AMD, the tiny drusen grow together, form larger deposits, and harden. They can interfere with the normal function of the retina. Most people with drusen have no symptoms. Visual symptoms that happen along with drusen are typically a sign that AMD is developing.
It is important that people who have drusen regularly see an ophthalmologist to monitor changes and to handle complications.
