Observational Study of DME Following Scatter Laser Photocoagulation

The development or worsening of macular edema following full scatter photocoagulation is a well recognized occurrence. However, there is limited literature in this regard. The purpose of this study is to determine the incidence and extent of macular edema following scatter laser photocoagulation surgery using optical coherence tomography (OCT) in eyes without macular edema prior to scatter laser photocoagulation and to explore whether the incidence and extent of macular edema varies according to the number of sittings included in the treatment regimen. Study eyes will receive one of two types of scatter photocoagulation with results compared through use of OCT and photography images, as well as visual acuity testing.
