There are two types of laser that are applied to the retina:
Pan-Retinal Photocoagulation (PRP) laser is applied when there is a growth of abnormal blood vessels in the retina, which can occur due to an impairment in the blood supply to the retina in conditions such as severe diabetic retinopathy or following retinal vein occlusion. The laser causes shrinkage of the abnormal blood vessels, thereby reducing the risk of them bleeding and causing loss of vision.
Macular Laser is used when there is fluid from leakage of tiny blood vessels in the macula region of the retina. As the macula is the part of the retina that is responsible for detailed vision, any fluid that leaks into this area can lead to a loss of vision – such as in Diabetic Macular Oedema and Branch Retinal Vein Occlusion.
