Retinal detachment
What is it?
Retinal detachment is a serious medical condition in which the retina, the layer of light-sensitive tissue at the back of the eye, detaches from its normal position. The retina is essential for vision, as it converts light into nerve signals that are then sent to the brain.
The causes
Retinal detachment can be caused by several factors, including:
- Holes or tears in the retina: These openings allow vitreous fluid (the transparent gel that fills the eye) to pass under the retina, lifting it up.
- Vitreoretinal traction: the vitreous can shrink and pull on the retina, causing tears.
- Ocular trauma: A direct blow to the eye can cause retinal detachment.
- Medical conditions: Certain conditions such as diabetes or eye inflammation can increase the risk.
The symptoms
Symptoms of retinal detachment may include:
-
Sudden appearance of floaters: Small spots or threads that appear to float in the field of vision.
-
Flashes of light: Flashes of light into one or both eyes.
-
Shadow or veil: A shadow or veil that begins in peripheral vision and moves towards the center.
-
Loss of vision: Sudden or progressive loss of vision.
Retinal detachment treatments
Treatment of retinal detachment is usually a medical emergency and may include:
- Surgery: Various surgical procedures can be used to repair the retina, such as vitrectomy, scleroplasty or pneumatic retinopexy.
- Laser or cryotherapy: These treatments can be used to seal holes or tears in the retina.
- Prevention: Although not all retinal detachments can be prevented, certain measures can reduce the risk:
- Regular eye examinations: Especially for high-risk individuals.
- Eye protection: Wear safety goggles during hazardous activities.
- Managing medical conditions: Controlling conditions such as diabetes.

In the days following the operation, your surgeon will suggest a post-operative position for your retinal detachment. To promote healing, strict rest is recommended.
Because of the gas in the eye, you should not fly or climb to altitudes of over 1,000 meters. The gas resolves spontaneously between 2 and 8 weeks after the operation.
