Panretinal Photocoagualtion (PRP)

What is panretinal photocoagulation (PRP)?

Panretinal photocoagulation (PRP) is when laser is used to create small burn scars over an area of retina. Usually PRP is applied to the areas of retina that have poor blood circulation and receive little oxygen. The purpose of PRP is to prevent formation of abnormal blood vessels in over the retina, optic nerve head, or in the front of the eye. These abnormal blood vessels can bleed inside the eye, cause severe retinal detachments or severe forms of glaucoma. 

What conditions are treated by panretinal photocoagulation (PRP)?

Panretinal photocoagulation (PRP) is usually used to treat neovascularization (formation of abnormal blood vessels) due to diabetic retinopathy or retinal vein occlusion.

How is panretinal photocoagulation (PRP) done?

To perform panretinal photocoagulation (PRP) in the office, first the pupil will be dilated by dilating eye drops. The patient will be sitting at the laser machine or lying on a reclining chair. Using special lenses, the ophthalmologist will apply laser to create small burn scars over the desired area of the retina. The procedure takes a few minutes.

What are some side effects and risks of panretinal photocoagulation (PRP)?

  • During the procedure the patient may feel a sharp pain or a dull soreness. The eye may remain sore for about a day after the procedure. However, most patients tolerate the procedure well.

  • The laser light is quite intense and can cause blurred vision for a short time following the procedure. 

  • Rarely a scar membrane can form over the center of the retina in years after the procedure.

  • Accidental laser to the center of the retina
