What is it?
Retinal laser treatment (laser photocoagulation) uses focused light energy to create small, controlled scars in the retina. These scars can seal the retina around a tear or reduce the growth of abnormal blood vessels.
Why it may be recommended
Laser treatment may be recommended for retinal tears, proliferative diabetic retinopathy, some forms of macular oedema and some retinal vascular conditions.
How it is performed
The treatment is usually done in the clinic after the pupil is dilated and anaesthetic drops are applied. A special contact lens on the eye focuses the laser. Some treatments are completed in one session; others need several.
Preparation
Because the pupils are dilated, vision stays blurred for several hours afterwards. Do not drive until it has returned to normal.
Recovery
Most people resume normal activities soon after treatment. Mild discomfort, glare or temporarily blurred vision may occur.
Possible risks
Possible risks include temporarily blurred vision, reduced night or side vision after extensive treatment and, rarely, damage to central vision. Laser treatment lowers but does not remove the risk of complications such as retinal detachment.
Follow-up
Follow-up examinations check whether the treatment has worked and whether more treatment is needed.
