When a retinal detachment occurs, the best time to treat it is at that time. Do not wait, because waiting will cause the detachment to enlarge and even cause retinal detachment. If you wait 1-2 days for the retinal detachment to involve the macular area, even if the retina can be reset by surgery later, the visual function will be greatly affected, so if the retinal fissure is found to be particularly small and has not yet caused the fissure of retinal detachment, you can use laser treatment to close the fissure completely in time, so that The possibility of retinal detachment in the future is very small. Retinal fissures are common in patients with high myopia or eye trauma, which may have clinical symptoms, including black shadows in front of the eyes and flashing sensations.
