- Retinal fundus
The interior lining of the eyeball, including the retina (the light-sensitive screen), optic disc (the head of the nerve to the eye), and the macula (the small spot in the retina where vision is keenest). The fundus is the portion of the inner eye that can be seen during an eye examination by looking through […]
- Retinal pigment epithelium
The pigment cell layer that nourishes the retinal cells. The retinal pigment epithelium is located just outside the retina and is attached to what is called the choroid, a layer filled with blood vessels that nourish the retina.
- Retinal vasculitis
Inflammation of the tiny blood vessels of the retina. Retinal vasculitis ranges in severity from mild to severe. Damage to the blood vessels of the retina can cause minimal, partial, or even complete blindness. Retinal vasculitis by itself is painless, but many of the diseases that cause it can also cause painful inflammation elsewhere, such […]
- Retinal vein, central
The blood vessel that carries blood away from the retina of the eye. The counterpart to the central retinal vein is the central retinal artery, the blood vessel that carries blood into the eye and supplies nutrition to the retina.
- Retinitis pigmentosa
A group of inherited disorders in which abnormalities of the photoreceptors (the rods and cones) of the retina lead to progressive visual loss. Abbreviated RP. People with RP first experience defective dark adaptation (night blindness), then constriction of the visual field (tunnel vision), and eventually, late in the course of the disease, loss of central […]
