Panretinal Photocoagulation (PRP) is a laser eye treatment used to manage abnormal blood vessel growth in the retina, particularly in advanced diabetic retinopathy. These fragile blood vessels can bleed into the eye or contribute to retinal complications that may affect vision. PRP uses controlled laser spots on selected areas of the peripheral retina to reduce the retina’s demand for oxygen and help limit the growth of abnormal blood vessels.
When Is PRP Recommended?
An ophthalmologist may recommend PRP laser treatment when retinal examination shows a significant risk of bleeding or other vision-threatening complications. It is commonly considered for proliferative diabetic retinopathy and may also be used in certain other retinal conditions involving abnormal blood vessel growth. Your doctor will determine whether PRP is appropriate after a detailed eye examination and, when needed, retinal imaging.
What Happens During PRP?
PRP is generally performed as an outpatient procedure. Numbing eye drops are used, and a special lens may be placed on the eye to help the ophthalmologist deliver precise laser treatment. Multiple laser spots are applied to areas of the peripheral retina. Treatment may be completed in one session or divided into several sessions depending on the condition and extent of retinal changes.
