Current therapy of diabetic retinopathy: laser and vitreoretinal surgery.

The advent of laser surgery and pars plana vitreous surgery has enhanced the vision and improved the lifestyle of the diabetic patient. Further research including use of the diode laser and improved vitreoretinal technology most likely will improve the current management of the diabetic patient. In addition, early detection and diagnosis of diabetic retinopathy will lead to earlier treatment and hopefully prevention of loss of sight. Future research to define the role of metabolic control of serum glucose and its relationship to diabetic retinopathy is necessary.
