When retinal detachment fails after external surgical treatment, it is recommended to have another surgical treatment to reset the retina as soon as possible instead of having to wait for a period of time. Retinal detachment is a common disease in ophthalmology, which is usually caused by trauma or the existence of retinal perforation and the pulling factor in front of the retina, resulting in the detachment of the retina from the position close to the wall of the eyeball, which will cause the patient to suffer from vision loss and visual field defects, and other symptoms, and the diagnosis can be confirmed through funduscopic examination and ultrasound examination of the ophthalmology. Once detected, the retina should be reset through surgical treatment as soon as possible in order to restore vision. If the surgery is not timely, it will lead to irreversible damage to the retinal function and make it difficult to restore vision. If the retina is not restored after external surgery, it is not recommended to wait for a period of time, but to arrange for a second surgery to restore the retina as soon as possible. The specific situation needs to be examined by an ophthalmologist to formulate a treatment plan.
