FLT laser

This stands for Focal Laser Therapy and is the term used to describe most laser treatments used on the retina. For example, FLT laser can be used to seal leaking microaneurysms from diabetic retinopathy.  Larger areas of retinal swelling and macular edema can be treated with FLT laser spots applied in a grid pattern to help peg the retina back into place.  Small retinal tears can be isolated by sealing the surrounding retinal tissue with FLT laser spots – this keeps the tear from extending and turning into a retinal detachment. FLT laser spots are targeted to specific areas of the retina and is different than PRP (panretinal photocoagulation).  With PRP, hundreds of laser spots are created throughout the entire peripheral retina in an attempt to save the central vision (typically used in cases of neovascularization from diabetic retinopathy or a CRVO).
