Patients with retinal detachment may suffer from dark shadows in front of their eyes, visual field loss, and vision loss. 1. Black shadow in front of eyes: retinal detachment is the separation of neuroepithelial layer and pigment epithelial layer of retina, the detached part of retina can not perceive light stimulation, which can lead to black shadow in front of eyes of patients. 2. Visual field loss: when the condition of retinal detachment is more serious, the scope of black shadow blockage in front of the eyes of the patient is larger, and the symptoms of visual field loss may appear. 3. Loss of vision: Because the detached retina can not perform its normal function, the patient may suffer from loss of vision. The longer the retinal detachment lasts, the more serious the vision loss will be, and the patient may even be at risk of blindness. It is recommended that patients with detached retinas seek prompt medical attention to evaluate their condition and follow the doctor’s instructions for treatment.
