Choroidal neovascularization after laser photocoagulation for diabetic macular edema

Ophthalmology. 1990 Apr;97(4):503-10; discussion 510-1. doi: 10.1016/s0161-6420(90)32574-5.


Choroidal neovascular membranes (CNVMs) developed in eight patients after photocoagulation for clinically significant diabetic macular edema (DME). The CNVMs developed in areas where Bruch's membrane was ruptured and were diagnosed 2 weeks to 5 months after treatment. Only six patients had symptoms. The CNVMs were treated in four patients; final visual acuity was poor in all eight patients. This serious complication that follows laser treatment for DME may be related to the use of repeated small-size, short-duration laser or intense laser burns, or both.
