Retinal detachment surgery includes external and internal procedures. The external surgical procedure includes anesthesia, cutting open the bulbar conjunctiva, exposing the sclera, treatment of the retinal tear, draining the fluid, applying top pressure to the retina, and ligation, etc. The internal surgery includes anesthesia, opening the eyelids, making a puncture opening through the conjunctiva, removing the vitreous body, resetting the retina, closing the retinal tear with laser, and injecting silicone oil or gas. 1. External surgery: first anesthesia, after the onset of anesthesia, incise the conjunctiva, fix the inlet tube on the sclera at the lower edge of the external rectus muscle, and make 2 more scleral incisions at 2 o’clock and 10 o’clock positions. The vitreous cutting head and light guide fiber enter the vitreous cavity through the upper 2 incisions, the central vitreous and posterior pole cortex are removed, and the retinal fissure is closed using a laser, and silicone oil or gas is injected. 2. Internal surgery: Anesthesia is given to the retrobulbar and orbicularis oculi muscles, the bulbar conjunctiva is cut along the corneal limbus, the extraocular rectus muscle is detached, the subretinal fluid is drained and combined with extra-scleral pressure or intraocular injection of gas to reset the retina at the site of the laceration, the fluid is drained, the vitreous cavity is injected with gas or silicone oil, and the combined scleral cuffing procedure is required if necessary, with the pre-positioned scleral retinal fixation line being ligated at the end. You can consult your clinical ophthalmologist for specific surgical procedures, and you need to seek medical attention if you experience any symptoms of eye discomfort.
