Retinal detachment is a serious eye condition that occurs when the retina, which is the layer of tissue at the back of the eye responsible for sensing light and sending visual signals to the brain, becomes separated from its underlying support structure.
Retinal detachment can cause a range of vision problems, from blurry or distorted vision to a complete loss of vision in the affected eye. It is considered a medical emergency that requires prompt treatment to prevent permanent vision loss.
There are several types of retinal detachment, including:
- Rhegmatogenous retinal detachment: This is the most common type, and it occurs when a tear or hole develops in the retina, allowing fluid to pass through and accumulate under the retina.
- Tractional retinal detachment: This occurs when scar tissue on the retina pulls the retina away from its underlying support structure.
- Exudative retinal detachment: This occurs when fluid accumulates under the retina due to inflammation, injury, or other causes.
Risk factors for retinal detachment include age, nearsightedness, a history of eye injury or surgery, and certain medical conditions such as diabetes. Symptoms of retinal detachment can include sudden flashes of light, floaters (small specks or spots that float across your field of vision), and a curtain-like shadow over your visual field.
Treatment for retinal detachment typically involves surgery to reattach the retina and prevent further vision loss.
