Surgical Retina

Because of the advancement of microsurgical techniques, wide-field imaging, and a greater knowledge of intricate biologic processes, retinal surgery has dramatically advanced during the last 20 to 30 years. Numerous disorders that were once blinding are now more successfully treated, including diabetic retinopathy, recurrent retinal detachments, and retinopathy of prematurity. The two main types of retinal surgery are vitrectomy and scleral buckling. To relieve the circumferential traction and stabilise the retina in the area of the retinal tear, standard scleral buckling surgery often entails the implantation of a firm silicone band around the equator of the eye. The scleral buckle changes internal fluid dynamics and slows the buildup of subretinal fluid. In order to create a retinal adhesion (retinopexy) to the underlying choroid in the area of the tear, either laser therapy or cryotherapy is utilised. A buckle and chorioretinal adhesion work together to restore 80% of rhegmatogenous retinal detachments. The retina may occasionally be reattached using retinopexy and an intraocular gas bubble. Pneumatic retinopexy is the name of this procedure.

Three small incisions are made in the sclera at the start of the vitrectomy procedure. While the other two are used to insert apparatus into the posterior region of the eye, one sclerotomy is designed to accept an infusion line. Through a surgical microscope with multiple lenses to enable the surgeon to see the aberrant anatomy, the doctor can see inside the patient's eye. To accomplish careful manipulation of the retina, a variety of tools like lighted picks, forceps, endolaser probes, and scissors are used. It is possible to reattach the retina using silicone oil, silicone gas, or heavy liquids. Treatment for ischemic retina using laser photocoagulation closes the retinal tear.
