Retinal detachment is a common condition of the retina of the eye that usually manifests itself as a loss of vision in one eye, often with dark shadows obscuring the eyes, a curtain-like or drapery-like covering in front of the eyes, and dark shadows that are essentially stationary or may gradually enlarge. When retinal detachment occurs in the macula, vision may be distorted, distorted, larger or smaller, or there may be a dramatic loss of vision with only light perception remaining. In addition, some retinal detachments may also present with changes such as floaters, where dark shadows float in front of the eyes or there is a flashing sensation. It is rare to have retinal detachment in both eyes at the same time. Therefore, it is recommended to go to the ophthalmology department of the hospital as soon as possible when the above symptoms occur, for fundus examination, as well as eye photography, OCT, etc., to clarify the retinal condition of the eyes, and if there is really a retinal detachment, it is necessary to operate as soon as possible, in order to prevent blindness.
