Small yellowish-white lesions located between the retinal pigment epithelium and Bruch's membrane are known as

  1. Drusen

  2. Hemorrhages

  3. Pterygium

  4. Entropion

The correct answer is: Drusen

Small yellowish-white lesions located between the retinal pigment epithelium and Bruch's membrane are known as Drusen. Drusen are a hallmark of age-related macular degeneration (AMD). They are composed of lipids, proteins, and cellular debris and can be seen during a dilated eye exam. Hemorrhages are characterized by the leaking of blood into the retina or vitreous humor and are not related to the description provided in the question. Pterygium is a fleshy growth on the conjunctiva that may extend to the cornea but is unrelated to the location and appearance described. Entropion, on the other hand, refers to an inward turning of the eyelid margin, which is not relevant to the context of the question.
