What is Panretinal photocoagulation for?
Panretinal photocoagulation (PRP) is a mainstay of therapy for retinal ischemic disease. The procedure involves creating thermal burns in the peripheral retina leading to tissue coagulation, the overall consequence of which is improved retinal oxygenation.
Can retinal detachment be treated with laser?
Laser Photocoagulation The laser emits a beam of light that travels through the eye and burns the area around the retinal tear or detachment to create a scar. This scar tissue helps seal the tear or reattach a detached portion of retina to underlying tissue.
Is Panretinal photocoagulation surgery?
Proliferative retinopathy is treated with laser surgery. This procedure is called pan-retinal photocoagulation or PRP. PRP helps to shrink the abnormal blood vessels. Your doctor places 1,000 to 2,000 laser burns in the areas of the retina away from the macula, causing the abnormal blood vessels to shrink.
In which patients the photocoagulation is used?
Diabetes can harm the eyes by causing diabetic retinopathy. It is one of the most common eye diseases that needs laser photocoagulation. It can damage the retina, the back part of your eye. The most severe from of the condition is proliferative diabetic retinopathy, in which abnormal vessels grow on the retina.
Which laser is used in Panretinal photocoagulation?
According to DRS protocol using a standard argon-type laser PRP, settings include burns that range approximately 200μ to 500μ in size, pulse durations of 100 milliseconds, and 200-250 mW of power. The goal is to produce burns that are grey in color; and avoid dense white burns.
Is Panretinal photocoagulation safe?
After pan-retinal photocoagulation, blurred vision is very common. Usually, this blur goes away, but in a small number of patients some blur will continue forever. Serious complications with pan-retinal photocoagulation are extremely rare, but like any surgical procedure, it does have risks.
How long does Panretinal photocoagulation take?
The laser is applied with either a light worn on the doctor’s head or by a microscope with a chin rest similar to the one used in clinic to examine your eyes and a special contact lens. The treatment usually takes 15-30 minutes depending on how much treatment is required in your particular circumstance.
