Retinal detachment
Retinal Detachment
Retinal detachment (pronounced: /rɪˈtɪnəl dɪˈtætʃmənt/) is a serious eye condition that occurs when the retina separates from its underlying layer of support tissue.
Etymology
The term "retinal detachment" is derived from the Latin words "retina" meaning "net" and "detachment" meaning "to draw away".
Definition
Retinal detachment is a medical emergency that can lead to permanent vision loss if not treated promptly. It is characterized by the pulling away of the retina from the blood vessels that supply it with oxygen and nutrients, leading to the death of retinal cells and potential blindness.
Symptoms
Symptoms of retinal detachment include sudden appearance of floaters, flashes of light in the peripheral vision, and a shadow or curtain-like effect over the visual field.
Causes
Retinal detachment can be caused by a variety of factors, including aging, eye injuries, tumors, cataract surgery, high myopia, and certain genetic disorders.
Treatment
Treatment for retinal detachment often involves surgery to reattach the retina to the back of the eye. This can be done through a variety of methods, including pneumatic retinopexy, scleral buckle, or vitrectomy.
