23-gauge transconjunctival vitrectomy in eyes with pre-existing functioning filtering blebs

چکیده
BACKGROUND We investigated the outcome of 23-gauge transconjunctival pars plana vitrectomy (23G PPV) for the treatment of vitreoretinal disorder in patients with prior trabeculectomy. METHODS We retrospectively reviewed medical records of 23G PPV in 11 eyes that had functioning filtering blebs after trabeculectomy. The main outcome measures were the visual acuity, intraocular pressure (IOP) and subconjunctival fluid height in bleb by anterior segment optical coherence tomography (OCT) before and after the surgery. RESULTS Eyes that had 23G PPV showed improvement of visual acuity after the surgery (P =0.003). Mean IOP was 13.82 mmHg before 23G PPV and 15.82 mmHg at 6 months postoperatively, which was statistically insignificant (P = 0.758). The bleb was observed before and after surgery using anterior segment OCT, and the difference in subconjunctival fluid was not statistically significant (P =0.172). CONCLUSIONS 23G PPV did not adversely affect bleb function in eyes with prior trabeculectomy.

Transconjunctival sutureless 25-gauge vitrectomy with newly designed microcannulas.
AIM To evaluate the usefulness of the newly designed 25-gauge (25-G) microcannula for transconjunctival sutureless vitrectomy (TSV). METHODS 25-G TSV was performed on 20 consecutive eyes with the newly designed 25-G microcannulas. We studied usefulness, intraoperative and postoperative complications in these cases. RESULTS No complications were recognized during surgery. Postoperative compl...

PURPOSE To evaluate the safety and efficacy of different methods of transconjunctival cannulated vitrectomy versus conventional non-cannulated vitrectomy in various vitreoretinal disorders. METHODS A prospective randomized study was done from August 2009 to February 2011. The study included 129 eyes of 122 patients, randomly divided into four groups. Group 1 comprised 34 eyes operated on usin...

PURPOSE To compare the efficacy and safety of 23-gauge transconjunctival vitrectomy with the conventional 20-gauge method in idiopathic epiretinal membrane and macular hole surgery. METHODS Sixty-one consecutive patients undergoing vitrectomy for idiopathic epiretinal membrane and macular hole were recruited to either 20- or 23-gauge vitrectomy groups and prospectively evaluated. Surgical suc...
