Laser for peripheral retinal degeneration, retinal laser photocoagulation, is permanent, and permanent scar tissue is formed when the laser spot is stabilized, but the duration of the effect is maintained in relation to the disease itself. Retinal laser photocoagulation is a method of localized retinal scarring using the thermal coagulation effect of the laser according to a certain photocoagulation range, photocoagulation energy and photocoagulation frequency. Retinal laser photocoagulation can reduce the thickness of the retina in the corresponding area, reduce the metabolic demand of the retina, which can make the inner layer of the retina richer in oxygen and nutrient supply, increase the supply of oxygen to the undamaged location, effectively alleviate the problems of ischemia and hypoxia of the retina, and at the same time, it can also effectively inhibit the secretion of vascular endothelial growth factor, regulate the permeability of the blood vessels, and improve the clinical symptoms of patients with endophthalmopathy. The causes of peripheral retinal degeneration are diverse. Genetic factors, pathologic myopia, and advanced age are all causes of peripheral retinal degeneration, and new areas of degeneration may still be formed in the untreated retina after laser treatment, which requires complementary laser treatment, or prophylactic laser treatment. The duration of maintenance of peripheral retinal lasering is related to the specifics of the disease. When lasering fails to improve the condition of the fundus, or when retinal tears or retinal detachment develop, aggressive surgical treatment is required. When peripheral retinal degeneration occurs, it is recommended to go to the ophthalmology clinic of a regular hospital for consultation.
