Detached retina

Detached Retina

A detached retina (pronounced: dɪˈtætʃd ˈrɛtnə) is a serious eye condition that occurs when the retina separates from its underlying layer of support tissue. The retina cannot function when these layers are detached, and without prompt treatment, it can lead to permanent vision loss.

Etymology

The term "detached retina" comes from the Latin detegere, meaning "to uncover", and the Latin retina, which is derived from rete, meaning "net". This refers to the net-like arrangement of cells in the retina.

Causes

A detached retina is usually caused by a tear or hole in the retina that allows fluid to get under it and lift it away from the back of the eye. Other causes can include trauma, advanced diabetes, and inflammatory eye disorders.

Symptoms

Symptoms of a detached retina can include sudden flashes of light, a sudden increase in floaters, a dark shadow over part of the field of vision, and a sensation of a curtain being drawn over the eyes.

Treatment

Treatment for a detached retina involves surgery to reattach the retina to the back of the eye. The type of surgery depends on the severity and location of the detachment. Options include vitrectomy, scleral buckle, and pneumatic retinopexy.
