A separation of the retina from its connection at the back of the eye. The separation usually results from a tear (that is, a rent or rip, not a tear drop) in the retina, which often occurs when the vitreous gel pulls loose or separates from its attachment to the retina. Once the retina has torn, the vitreous liquid can pass through the tear and accumulate behind the retina. The build-up of fluid behind the retina is what separates (detaches) the retina from the back of the eye. Vision loss occurs if the detached retina is not repaired.

Electrophysiologic retinal testing .
- 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.
