Materials and Methods: Ten eyes of 10 patients operated with 25 gauge transconjunctival sutureless pars plana vitrectomy included in this study. Patients were examined preoperatively, and first day, first month and third months postoperatively. Visual acuity, tonometric measurement, slit lamb evaluation and posterior segment examinations were recorded. All patients were operated with standard 25 gauge vitrectomy technique by entering three-port tunnel sclerotomies.

Results: The mean age of the patients was 54.90 years (range: 17-73). None of the eyes developed endophthalmitis. No case required a suture to close the conjunctival or scleral opening site. In one case standard technique was necessary due to inability of removing and peeling extensive fibrovascular and epiretinal membranes by 25 gauge technique and necessity of silicon oil injection. Overall, the median preoperative visual acuity was 1 meter finger counting, and the median postoperative visual acuity after a mean follow-up of 3 months was 20/100. The median preoperative intraocular pressure was 15.8 mmHg, whereas the median intraocular pressure on the first postoperative day was 11.8 mmHg. We observed one case of hypotonia at the postoperative first day. With medical treatment intraocular pressure of this eye returned to the normal at the second postoperative day.

Conclusion: 25 gauge transconjunctival sutureless pars plana vitrectomy is an effective and safety technique for selected cases of the posterior segment. Further study with longer follow-up and large series is warranted to assess the long term efficacy. Keywords : Pars Plana Vitrectomy, 25 gauge, Transconjunctival
