After successful retinal detachment surgery, patients should not think that they are in a safe and will never have a retinal detachment again. Regular fundus examinations are still needed after surgery to detect possible new fissures or retinal degeneration. In addition, foramen ovale detachment has a tendency to occur in both eyes and should be routinely examined in the contralateral eye with dilated pupils for early detection and timely management of the lesion. People at high risk (elderly, myopic) should have regular fundus examinations for early detection of retinal fissures or degeneration even if they have not experienced retinal detachment. The presence of retinal fissures and/or retinal degeneration is a high risk factor for retinal detachment and may not require surgical treatment when it has not yet caused retinal detachment. Currently, laser photocoagulation or condensation can be used to close the degeneration and fissure. Both retinal laser photocoagulation and condensation are used to scar the retinal tissue so that the adhesion to the epithelial layer and choroidal tissue is greater than the pulling force of the vitreous on the retina, thus preventing further progression of the lesion. The initial period after retinal detachment requires more rest, but not absolute bed rest; different positions and head positions should be adopted according to medical advice, such as silicone oil or gas filling for internal retinal repositioning surgery, which requires downward facing prone position or low head position, while supine or normal position for external retinal repositioning surgery. In addition, the following points should be noted: 1. get enough sleep; 2. avoid excessive eye use and eye rubbing; 3. eat more vegetables and fruits; eat nutritious and easily digestible food to promote recovery; 4. avoid smoking, alcohol, spicy and hard food, and keep bowel movements smooth; 5. avoid breath-holding, coughing, strenuous exercise, heavy physical labor and head vibration, especially avoid eye trauma; 6. lower the head less and avoid 7. Exercise in moderation, do not overexert yourself, do not dive or dive; 8. Do not rub the operated eye to avoid eye infection and inflammation; 9.
