panretinal photocoagulation
Pronunciation: pan-RET-ih-nal foh-toh-koh-AG-yoo-LAY-shun
Laser treatment applied to the peripheral retina to reduce abnormal blood vessel growth in diabetic retinopathy.
Full Definition
Panretinal photocoagulation (PRP) is a laser therapy technique used primarily to treat proliferative diabetic retinopathy and other ischemic retinal conditions. The procedure involves applying 1,200-1,600 laser burns to the peripheral retina, deliberately destroying ischemic tissue to reduce the production of angiogenic factors. This helps prevent further neovascularization and reduces the risk of vitreous hemorrhage and retinal detachment. Treatment is typically performed in multiple sessions to minimize patient discomfort and reduce complications.
Usage
Usage note: Commonly abbreviated as PRP; distinguish from focal laser treatments which target specific lesions.
