What is retinal detachment?
Retinal detachment is a critical condition in which the retina separates from its usual position at the back of the eye, disrupting the normal visual pathway. The retina depends on the layer beneath it for its blood supply, so once it detaches it begins to lose function. Without prompt treatment, retinal detachment can cause severe and permanent vision loss, which is why early diagnosis and surgical treatment are crucial to preserving eyesight.
Warning signs
The symptoms typically come on suddenly and are painless, which is why they are sometimes ignored.
- Sudden flashes of light, often at the edge of vision and more noticeable in dim conditions
- A sudden increase in floaters, sometimes described as a shower of black spots or cobwebs
- A shadow or curtain spreading across part of the field of vision
- A sudden drop in vision in one eye
- Distortion of straight lines or objects
Any of these needs assessment the same day. Retinal detachment is painless, so the absence of pain is not a reason to wait.
Who is at risk?
Recognised risk factors include short-sightedness, previous eye surgery including cataract surgery, a previous detachment in the other eye, a family history of retinal detachment , and eye injury. Anyone with these risk factors should have new flashes or floaters checked promptly rather than waiting to see whether they settle.
How it is diagnosed
Diagnosis is made through a dilated examination of the retina, sometimes supported by imaging. Mr El Housseini will examine both eyes, since a detachment in one raises the risk in the other.
How it is treated
Treatment depends on the type and extent of the detachment, and Mr El Housseini will explain which approach is right for your eye.
Vitrectomy removes the vitreous humour at the centre of the eye and replaces it with a saline solution, allowing the retina to be repositioned.
Scleral buckling places a silicone band around the sclera to push the detached retina back into position and seal retinal tears or holes.
Laser retinopexy uses focused laser energy to seal retinal tears before they progress to a full detachment, preventing further damage and reducing the risk of vision loss.
Full detail of each procedure, including prices, is on the Vitreoretinal Surgery page.
