Abstract

Purpose:  To compare the frequency of hypotony after 23-gauge (G) pars plana vitrectomy (PPV) with suture-less sclerotomy versus intrascleral hydration for sclerotomy closure in eyes with air/gas tamponade.

Study Design:  Quasi-experimental study.

Place and Duration of Study:  College of Ophthalmology and Allied Vision Sciences, Mayo Hospital, Lahore from November 2021 to May 2022.

Methods:  A total of 90 eyes were included who underwent PPV with air/gas tamponade. One group underwent PPV with suture-less sclerotomy while the other got intrascleral hydration for sclerotomy closure. Intraocular pressure (IOP) was measured pre and post-operatively at day one and day seven by applanation tonometry in all eyes. IOP of 6 mmHg or less was defined as hypotony. Primary endpoint measure was rate of early post-operative hypotony.

Results: A total of 90eyes of 90 patients, 40 (44.4%) males, and 50 (55.6%) females were included in the study. Five (5.6%) patients reported hypotony, out of which, only one (2.2%) case was seen in the intrascleral hydration group while rest (8.9%) were of the sutureless group. Sclerotomies requiring sutures were 4.44% (6 of 135) in sutureless group while 0.74% (1 of 135) in intrascleral hydration group. Paired sample T-test for the means of pre-operative and post-operative IOP was significantly different in both groups. For suture-less PPV, mean difference was 3.089 ± 7.960 mmHg (P = 0.013), while for the intra scleral hydration group, it was 3.778 ± 7.048 mmHg (p = 0.001).

Conclusion:  Intrascleral hydration is a suitable option for PPV sclerotomy closure without having any side effects.
