Retinal Laser Photocoagulation

What is Retinal Laser Photocoagulation

Ophthalmologists use retinal laser photocoagulation to treat an array of retinal disorders. Diabetic retinopathy, retinal vein occlusion, retinal breaks, central serous chorioretinopathy, and choroidal neovascularization are among the manifestations of these conditions. Contrary to many patient’s held perception, this treatment is not a surgical procedure. Instead, the doctor directs a focused laser beam of light on a specific location in the retina, generating heat energy that causes retinal coagulation and achieves the desired treatment.

Types and benefits of Retina Laser

Laser therapy is employed in different ways based on the specific type of retinal disorder.

Proliferative Diabetic Retinopathy (PDR)

Proliferative diabetic retinopathy (PDR) is an advanced stage of diabetic retinopathy that occurs when diabetes remains uncontrolled over an extended period, causing progressive changes in retinal blood vessels. This condition poses a significant threat to vision. Without prompt intervention, PDR can lead to complications such as abnormal vessel bleeding within the eyes and retinal detachment.

Retinal laser therapy is beneficial in managing PDR since it reduces the likelihood of these complications. The doctor uses pan-retinal photocoagulation (PRP) as the treatment approach for PDR.

The retina is a complete 360-degree structure essential for vision. Within it, the macula serves as the central area responsible for precise vision.

Proliferative diabetic retinopathy (PDR) is a progressed stage of diabetic retinopathy caused by uncontrolled diabetes for an extended period of time, resulting in progressive changes in retinal blood vessels. This condition is extremely dangerous to one’s vision. PDR, if not treated promptly, can result in adverse effects such as abnormal vessel bleeding within the eyes and retinal detachment.

Retinal laser therapy assists in the management of PDR because it lessens the likelihood of these complications. PDR is treated with pan-retinal photocoagulation (PRP) by the doctor. Laser therapy is directed at the poorly vascularized regions of the retina while sparing the macula in cases of proliferative diabetic retinopathy. The treatment is usually carried out in three to four sessions, gradually covering the nearly 360-degree retina with laser spots. This therapy effectively prevents the formation of abnormal blood vessels and the complications that accompany them.

Diabetic Macular Edema (DME)

Diabetic Macular Edema (DME) refers to the accumulation of abnormal fluid in the macula, which leads to loss of vision as a result of swelling. In certain instances of DME, retinal laser photocoagulation is advantageous. To reduce the swelling, this treatment involves applying small laser spots that aim for leaks of blood vessels in the macula.

Retinal Vein Occlusion (RVO)

Retinal Vein Occlusion(RVO) is a partial or total blockage in a vein that carries blood away from your retina. The symptoms may show blurred vision or loss of visual function in one eye, which can develop suddenly. The type of laser used in RVO is Pan Retinal Photocoagulation PRP. Small burns are made by laser in the areas of your retina that do not receive blood flow. This way the number of proteins (VEGF) that promote the formation of abnormal blood vessels is reduced.
