The incidence of primary retinal detachment is about 15% in both eyes, so when detachment has occurred in one eye, the other eye must be examined carefully after adequate pupil dilation. If an area of retinal degeneration is found, especially if there are already fissures and superficial detachments, appropriate measures should be taken to prevent further extension of the retinal detachment. If you have retinal detachment, especially complex retinal detachment, and the retina has been repositioned after surgery and partial visual function has been restored, it is a very difficult thing to do. How should I take care of my eyes? (1) Avoid heavy physical work and strenuous sports, such as diving, soccer, high jumping and running, etc. (2) Avoid excessive eye use to prevent the development of myopia. Watch TV and read newspapers appropriately, and pay attention to the combination of work and rest. (3) Patients with extra-scleral pressure can resume work within their ability one month after surgery, vitreous surgery is decided according to the situation, but overworking should be avoided. 3 months later, optometry can be considered to correct vision. (3) Ocular trauma and head shock injury should be avoided as much as possible to prevent retinal re-detachment. (4) If there is a flashing sensation or sparkle flicker in front of the eyes, you should immediately go to the hospital for dilated pupil examination of the fundus (including the contralateral eye) for early detection and timely treatment. (5) Even if the retina is reset, it should be checked regularly. (6) Learn and understand the relevant knowledge. The maintenance of retinal detachment patient’s eyes should be considered from various aspects and comprehensively, and the adjustment of daily work and relaxation are also very important.
