Patients with retinal thinning can undergo retinal laser treatment to prevent retinal detachment, but whether or not to undergo laser treatment depends on the patient’s condition. Usually, patients with high myopia will have retinal degeneration leading to retinal thinning, which may cause foraminal retinal detachment, and patients can have prophylactic fundus laser photocoagulation treatment to prevent retinal detachment effectively. If the patient has extensive retinal thinning due to aging or glaucoma, laser treatment is generally not necessary. The retina is usually divided into four quadrants, and the retinal laser can hit one quadrant at a time. Laser photocoagulation of the entire retina can make the retina more securely attached to the posterior tissues, and even after retinal tears occur, the risk of retinal detachment can be reduced to a certain extent. It is recommended that patients with fundopathy be seen promptly for evaluation of their condition and treatment as prescribed by their physician.
