Photocoagulation is a medical procedure that uses focused light energy, typically from a laser, to treat various eye conditions. It works by creating small burns in the tissue of the eye, which helps to seal off leaking blood vessels or to destroy abnormal tissue. This technique is commonly used to manage conditions like diabetic retinopathy and age-related macular degeneration. During the procedure, the patient may receive local anesthesia to minimize discomfort. The doctor carefully directs the laser to the affected areas, ensuring precision to protect surrounding healthy tissue. Photocoagulation can help preserve vision and prevent further damage to the eye.
