NCT04280770

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.

Outcome Measures

Primary Outcomes (3)

  • success rate

    success rate after first RD surgery and silicone oil removal

    42 days

  • The failure rate

    The failure rate after silicone oil removal

    42 days

  • number of surgical interference

    numbers of vitrectomies done after silicone oil removal

Study Arms (2)

Non retinal detachment group

SHAM COMPARATOR

35 participants did 23 vitrectomy followed for 3-6 months. After that, we removed the oil and followed them for 6 weeks.

Procedure: 23 PARS PLANA VITRECTOMY

retinal detachment group

ACTIVE COMPARATOR

15 participants did 23 vitrectomy followed for 3-6 months. After that, we removed the oil and followed them for 6 weeks.

Procedure: 23 PARS PLANA VITRECTOMY

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.
