Brief 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.

Study Arms (2)
Non retinal detachment group
SHAM COMPARATOR35 participants did 23 vitrectomy followed for 3-6 months. After that, we removed the oil and followed them for 6 weeks.
retinal detachment group
ACTIVE COMPARATOR15 participants did 23 vitrectomy followed for 3-6 months. After that, we removed the oil and followed them for 6 weeks.
Interventions
We 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. 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.
Eligibility Criteria
You may qualify if:
- they had retinal detachment,
- moderate degrees of PVR
- PVR ≥ Grade C
- previous buckle surgery
- pseudophakia.
You may not qualify if:
- the retinal tear was greater than 90 degrees
- presence of intravitreal foreign body
- previous vitrectomy done before
- if follow-up data were unavailable for a minimum follow-up of 6 months following the final retinal procedure.
