Drusen refers to the yellow deposits that form beneath the retina in the eyes. Some common synonyms for drusen include subretinal deposits, druse, drusenoid deposit, or retinal deposits. While drusen are common, especially among older adults, they can also indicate the presence of certain eye diseases, including age-related macular degeneration. Therefore, early diagnosis and treatment are critical to prevent further damage to the eyesight. It's important to speak with an eye specialist if you notice any changes in your vision as they may indicate the presence of drusen or other eye diseases.
