Retinal detachment is a serious vision-threatening fundus disease that can cause blindness. Depending on the condition of the lesion, retinal laser photocoagulation or surgery may be the treatment of choice. Retinal detachment is the separation of the retinal neuroepithelium from the pigment epithelium and can be classified as foraminogenic retinal detachment, exudative retinal detachment, and retinal detachment with retraction depending on the cause. Therefore, the treatment modality varies slightly depending on the cause. If the number of fissures is small and concentrated, and the extent of retinal detachment is small, only the superficial retinal detachment around the fissures, retinal laser photocoagulation can be chosen to close the fissures, thus preventing further detachment of retinal veins; if the extent of detachment is large and the fissures are relatively large, vitrectomy or extra-scleral ring ligation with pressure pad can be chosen depending on the case. This type of retinal detachment is mainly treated for primary diseases, such as exudative retinal detachment caused by hypertensive retinopathy during pregnancy, and the retinal detachment can usually be recovered after the blood pressure is stabilized. Retinal detachment caused by vitreous liquefaction, posterior cortical detachment and proliferative detachment is the most common cause of retinal detachment. In summary, the treatment of retinal detachment should be individualized according to the specific lesions and causes, and the appropriate treatment modality should be selected.
