Laser photocoagulation is a type of laser surgery that uses an intense beam of light to burn small areas of the retina and abnormal blood vessele beneath the macula. The burns form scar tissue that seala the blood vessels, keeping them from leaking under the macula. By sealing the leaky blood vessels, laser photocoagulation slows down, The buildup of fluid under the retina that distors the shape and position of the macula. The growth of scar tissue and the abnormal membrane under the retina, both of which damage the cells in the macula. But, also there is some of riskk of using a laser.. laser photocoagulation burns and destroys part of the retina and often resuls in some permanent vision loss. This is usually unavoidable. In this paper we show a case report of patient with proliferative diabetic retinopathy. We perfomed a panretinal Argon laser photocoagulation. After the laser treatment and regulation a level of glucosis in blood, our patient a good visual acuity and he will not need vitreoretinal surgery.
