Retina Detachment
A retinal detachment occurs when the retina—the thin, light-sensitive tissue lining the back of the eye—separates from its normal position. This is a serious condition that can lead to permanent vision loss if not treated promptly.
Retinal detachment is relatively uncommon, affecting about 1 in 10,000 people per year. It is more likely to occur in people with high myopia (nearsightedness), a family history of retinal detachment, a history of eye trauma, or after cataract surgery.
Common Signs of Retina Detachment:
-
Sudden appearance of flashes of light in your vision
-
A sudden increase in floaters (spots or cobweb-like shapes)
-
A shadow, curtain, or gray veil across part of your vision
-
Sudden blurred or distorted vision
How Retina Detachment Can Be Corrected or Managed:
Treatment for retinal detachment is urgent and always requires surgery to reattach the retina and preserve vision.
The exact procedure depends on the type, size, and location of the detachment:
-
Laser or cryotherapy (freezing treatment): If the retina is only torn but not fully detached, a laser or freezing treatment may be used to seal the tear and prevent progression.
-
Pneumatic retinopexy: A small gas bubble is injected into the eye to push the retina back into place. Laser or cryotherapy is then used to seal the tear.
-
Scleral buckle: A silicone band is placed around the outside of the eye to gently press it inward, helping the retina reattach.
-
Vitrectomy: The vitreous gel inside the eye is removed and replaced with a gas bubble or silicone oil to flatten the retina against the back of the eye.
-
Success rates: With prompt treatment, about 90% of retinal detachments can be repaired with one or more surgeries, though final vision often depends on how quickly treatment is received and whether the macula (the central retina) was affected.
