Until the introduction of anti-VEGF medications, focal and grid laser photocoagulation was the standard treatment for CSME.
The grid laser destroys photoreceptors in the retina thereby decreasing the oxygen demand, while the focal laser targets specific leaking microaneurysms responsible for the macular edema.
The Early Treatment Diabetic Retinopathy Study (ETDRS) reveals that focal laser photocoagulation plays a beneficial role and reduces the rate of moderate visual loss by 50%.5 Patients having media opacity like cataract at times make it impossible for the doctor to do complete macular grid laser so there is a need for an alternative or adjunctive treatment.
Procedure of grid photocoagulation: Laser photocoagulation was conducted in a grid pattern under topical anesthesia as described by the Early Treatment Diabetic Retinopathy Study (ETDRS), Grid laser was performed with Iridex Oculight GL, frequency doubled diode pumped laser with wavelength 532 nm.
