Panretinal Photocoagulation
Panretinal photocoagulation, also known as PRP or scatter laser treatment, is a minimally invasive laser procedure used to seal or destroy leaking blood vessels on the retina. This method of treatment is effective in shrinking and preventing the growth of new blood vessels around the retina. In addition, a panretinal photocoagulation may reduce the occurrence of vitreous bleeding or retinal distortion in those patients with proliferative diabetic retinopathy, an advanced stage of diabetic eye disease.
During the panretinal photocoagulation procedure, a laser beam is directed to the leaking blood vessels. The laser creates scar tissue around the area slowing the growth of any new or abnormal blood vessels. While the procedure is unable to restore vision that has already been lost, a laser panretinal photocoagulation can reduce the risk of vision loss, a major complication of proliferative diabetic retinopathy.
The panretinal photocoagulation procedure is usually performed on an outpatient basis with a local or topical anesthetic. Patients will need someone to escort them home after the procedure, since the pupils will be dilated for several hours. After the panretinal photocoagulation procedure, patients may experience blurry vision and mild pain for a day or two. Normal activities may be resumed with the surgeon's approval.
