Understanding the Visual System: Anatomy, Photoreceptors, and Adaptation Mechanisms

Explore the intricate anatomy of the eye, including the retina, pigmented layer, and key cells, such as photoreceptors and ganglion cells. Learn about intraocular fluid, glaucoma, and macular degeneration, including Stargardt disease. Discover how photoreceptors like cones and rods facilitate light detection and adaptation, influencing pupillary size and neural processes. Delve into conditions like retinitis pigmentosa and night blindness.
