Usually retinal tears are very serious diseases, but most patients have a good prognosis through active treatment. Retinoschisis is mainly related to retinal degeneration, vitreous degeneration, and posterior vitreous detachment, which tends to cause patients to suffer from flashing sensation and vision loss. Since retinal tears can cause visual field defects and retinal detachment in some patients, thus affecting the quality of life and health, retinal tears are generally a very serious disease and should be taken seriously. If a person is diagnosed with a retinal tear and actively cooperates with the doctor, the prognosis is usually good, which can help to improve the abnormal vision and other conditions. If no treatment is taken, complications such as retinal detachment and proliferative vitreoretinopathy may occur. It is recommended that people with retinal detachment should adjust their mindset and take active treatment under the guidance of doctors. They should also avoid strenuous exercise and protect their eyes to prevent eye trauma.
