The macula is the central part of the retina at the back of the eye. It is responsible for fine vision (reading, writing, watching television, and recognising faces). Patients with diabetes may develop macular oedema (swelling of the retina) due to leaking of fluid from blood vessels. This causes the vision to become blurred.
A course of three injections is recommended with each injection administered one month apart. The procedure is carried out in a clean environment using sterile technique. The eye is cleaned and local anaesthetic drops are given to numb the eye.
The eye may or may not be covered after the injection. If a pad is applied, this may be removed when you reach home.
