Retinal detachment due to collision, which has occurred for 7 days, can also be treated surgically if it meets the criteria for surgical treatment. In general, the sooner surgery is performed for retinal detachment caused by trauma, the better the outcome. After the eye is traumatized, the huge external impact will destroy the internal structure of the eye, and may tear the retina and cause the formation of subretinal fluid, causing retinal detachment. At this time, the patient will have symptoms such as vision loss and visual field defect, and need to reset the retina through surgical treatment as soon as possible. After retinal detachment, the photoreceptor cells and nerve cells in the retina lack nutrients from the choroid, which will lead to their apoptosis. Therefore, it is necessary to reset the retina as soon as possible in order to promote the restoration of vision. Patients with retinal detachment are advised to seek prompt medical attention to evaluate their condition and follow their doctor’s instructions.
