The laser treatment of the retina is used to treat PDR, non-central diabetic macular oedema (DME) and sometimes also severe non-proliferative diabetic retinopathy.
There are two primary types of laser treatment: the local treatment of the macula, which is the area of accurate vision, and panretinal photocoagulation (PRP) of the peripheral areas of the retina.
Laser treatment is proven to slow down the progress of retinopathy and the impairment of vision. It improves the flow of blood in the central area of the retina, which is important for retaining vision, improves the supply of oxygen to the retina, prevents the growth of new blood vessels and alleviates swelling (oedema) by reducing bleeding from the blood vessels.
Usually, the treatment is carried out during 1–2 outpatient clinic visits, preceded by eye drops that make the pupils larger. However, if necessary, the treatment can be repeated.
