What is it?
Retinal detachment surgery aims to close retinal breaks and reattach the retina to the tissue beneath it. The choice of technique depends on the type, extent and location of the detachment and on the individual eye.
Why it may be recommended
Surgery is needed when the retina has detached, because a detached retina cannot function and a prolonged detachment increases the risk of permanent loss of vision.
How it is performed
Techniques include pneumatic retinopexy (an expanding gas bubble injected into the eye, combined with freezing or laser treatment), scleral buckling (a silicone band placed on the outer wall of the eye) and vitrectomy with gas or silicone oil. Techniques are sometimes combined.
Preparation
Because timing matters, surgery is often planned quickly. Your general health and medicines are reviewed, and you receive instructions for the day of surgery.
Recovery
Head positioning may be needed for a period after surgery. When gas is used, flying and travelling to high altitude must be avoided until the gas has been absorbed. Vision recovers gradually, and the final result depends in part on whether the macula was detached.
Possible risks
Possible risks include redetachment, cataract, raised eye pressure, infection, double vision after scleral buckling, and the need for further surgery.
Follow-up
Regular examinations after surgery confirm that the retina stays attached.
