This is a basic technique for laser treatment with no alternative at present. Only through laser coagulation (when it can be performed), the condition of your retina can be stabilized in the long term. Retinal laser therapy prevents vision loss in 70% of patients with non-proliferative diabetic retinopathy. It is important to note that laser treatment does not always improve vision but stops its further deterioration. Patients with proliferative diabetic retinopathy need treatment of the whole retina. This technique is called panretinal laser coagulation. By removing the neo-vascularisations it prevents vision deterioration. It takes 3 to 6 procedures, 5-15 minutes each and is performed in an out-patient unit. Retinal laser therapy of blood vessels aims at reduction of edema, hemorrhages and proliferations of the area. In the case of peripheral retinal degeneration, as well as retinal breaks, retinoschisis and retinal detachment, the retinal laser encircles the affected area. A laser cerclage should be done of the whole peripheral retina.
