Summary

Objective: to evaluate anatomical and visual outcomes of 23-gauge vitrectomy for retinal detachment with silicone oil injection in fifty cases. The rate of recurrence, the incidence of proliferative vitreoretinopathy (PVR) and the value of risk factors. Participants and Methods: fifty cases with RD with mixture of epiretinal and subretinal membranes were collected. Pars plan vitrectomy, 23gauge vitrectomy were done to these cases, then silicone oil removed 6 weeks after primary surgery. Main Outcome Measures: The anatomical success rate,the failure rate ,the rate of retinal breaks in both groups, and reproliferation rate.

Detailed description

50 Patients were included if they had retinal detachment, moderate degrees of PVR, PVR ≥ Grade C, previous buckle surgery and pseudophakia. A good and correct assessment of the detached retina was done. Investigator followed the Lincoff rules to find the retinal breaks. Investigator performed a three-port vitrectomy: one infusion trocar and two instruments trocars. Non-contact wide-angle viewing systems (Resight- Biom) have a viewing field of 60-130° was used. Investigator used Perfluorocarbon liquid (PFCL) for attaching the retina with its gravity. Then performing PFCL against air exchange.The retina will be attached under air tamponade. Laser photocoagulation was performed in the air-filled eye. Investigator applied the laser effects confluently surrounding all retinal breaks. Then silicone oil (1000 centistokes) was injected as a final step and permanent tamponade.After 3-6 months investigator removed the silicone and examined the retina for 6 weeks after surgery to detect the recurrent cases.

Non-contact wide-angle viewing systems (Resight- Biom) have a viewing field of 60-130° was used. Put 23 needle attached to the automated pump for silicone oil extraction. Strict examination of the retina to detect new breaks or untreated breaks. Closure of the sclerotomies.
