| Purpose: To determine whether epiretinal membrane peeling in silicone oil-filled eyes can be safely performed by 25-gauge transconjunctival sutureless vitrectomy system (TSV).
Design: A retrospective noncomparative interventional study.
Methods: A prospective series of epiretinal membranes peeling in 19 silicone oil-filled eyes were performed using the 25-gauge TSV. The operating times at each of the steps of the operations were measured. The condition of leakage of silicone oil in puncture site was recorded. Follow-up ranged from 4 to 7.5 months. The visual acuity and intraocular pressures were measured preoperatively and postoperatively. The postoperative intraocular inflammatory response and observed intra-operative and post-operative complications were recorded.
Results: No patients enlarge the sclerotomy, and no patients required conventional scleral sutures, without ongoing leakage of silicone oil. The mean pre-operative IOP was 23.6 mmHg (range 15-31mmHg). The mean IOP on post-operative day 1 was 24.1mmHg (range 12-33mmHg). The mean IOP one week after surgery was 20.3 mmHg (range 13-30.0 mmHg). No surgical complications related to the TSV25 system were observed. There was a noticeable decrease in the amount of post-operative inflammation. The patients reported a noticeable decrease in post-operative discomfort following surgery with the TSV25 system. Epiretinal membranes in all the eyes were removed successfully.
Conclusion:Tranconjunctival vitrectomy using the TSV25 system can be safely and effectively performed without conventional scleral and conjunctival sutures, Which can minimize post-operative inflammation and patient discomfort.
