If the tears that cause retinal detachment are numerous, large, their locations are different from the usual ones, if the tear cannot be detected, if there are other accompanying diseases (such as intraocular hemorrhage), or if time has passed, vitrectomy surgery may be required. In vitrectomy surgery, retinal detachment is intervened from inside the eye. For this, small holes are made in the eyeball, vitreous fluid is cleaned with the help of some cutting and aspirating rods (probes) and light sources, the fluid accumulated under the retina is aspirated, the tears are closed, and laser treatment is applied. At the end of the operation, it is necessary to apply a buffer material into the eye so that the laser treatment applied to the torn area adheres and this effect continues. Depending on the situation, this buffer can be air and similar gases, or silicone oil. After the operation, the patient should use protective eye drops for a while and lie in a certain head position.
