What is the name for the small yellowish lesions located between the retinal pigment epithelium and Bruch's membrane?

The small yellowish lesions found between the retinal pigment epithelium and Bruch's membrane are specifically known as drusen. Drusen are significant in the context of age-related macular degeneration (AMD) as their presence can indicate the early stages of this condition. They result from the accumulation of waste products from the retinal pigment epithelium and are a key indicator ophthalmologists use to assess the health of the retina.

Understanding the function and implications of drusen is essential for recognizing potential retinal disorders. For instance, the presence of drusen may warrant increased monitoring for patients at risk of developing AMD. The other terms do not specifically refer to these lesions: exudates refer to fluid or protein that has leaked into the tissues, lesions are a broader term for any abnormal tissue area, and choroidal nevi are benign tumors of the choroid layer of the eye. Therefore, recognizing drusen is crucial for proper diagnosis and management of retinal health.
