These abnormal blood vessels, or “neovascularization,” are fragile and can bleed easily or cause further damage to the eye.
This type of laser treatment aims to treat these areas of retinal damage. This would help to stop the proliferation of new blood vessels and prevent further damage. This laser modality is used in conditions such as:
