Many retinal conditions require treatment with injection of therapeutic agents into the eye to achieve the best visual results or to stabilise eyesight. The retinal conditions include macular oedema which is leakage of fluid from the blood vessels into the central part of the retina called the macula, as a result of certain conditions such as retinal vein occlusions, diabetic retinopathy or inflammation (uveitis). It is successfully used to stabilise vision in wet age-related macular degeneration.
These injections include intravitreal agents such Lucentis, Eylea, Avastin, Ozurdex, Illuvien, Jetrea etc. The injections are administered under a local anaesthetic and are painless. The frequency depends on the type of injection and the retinal condition being treated.
