The Effect of Panretinal Photocoagulation On Optic Nerve
Ahmed Tamer Sayed Saif;
Abstract
In the early sixties, the diabetic retinopathy was considered as a part of its definition as predictable and non preventable but this statement is now considered incorrect. Thanks to laser pan retinal photocoagulation that changes the course, progression, and prognosis of diabetic retinopathy and maculopathy. So that diabetes now is not the leading cause of blindness in the western countries
The effect of pan retinal photocoagulation on the optic nerve is not well studied, evidenced by the very few papers directly related to the subject
During PRP the optic nerve can be damaged by:
1. Thermal: When direct coagulation of neovascularization on the optic disc is attempted.
2. Ischemic neuritis resulting from cutting the choroidal supply to the head of the optic nerve
3. Direct interruption of nerve fibers by high laser beam
power densities
Pan retinal photocoagulation can produce damage to all layers of the retina including the nerve fiber layer.
