Purpose:
To compare the visual outcomes and complication rates of idiopathicmacular hole repair between 20, 23, and 25-gauge pars planavitrectomy (PPV) systems.
Methods:
METHODS: This was a retrospective, consecutive, interventionalcase series of 107 eyes in patients with idiopathic, visuallysignificant macular hole that underwent elective repair withinternal limiting membrane peeling and gas tamponade. The mainoutcomes were visual acuity and postoperative complications.
Results:
RESULTS: No significant differences were found between the 20,23, and 25-gauge PPV groups in the improvement of visual acuityat 3, 6, and 12 months postoperatively (P 0.122, 0.605, 0.543,respectively). The mean improvement in one-year logarithm ofminimal angle resolution visual acuity was 0.39, 0.40, and 0.37in the 20, 23, and 25-gauge groups (P 0.317). There was a lowrate of post-operative complications in all groups.
Conclusions:
Idiopathic macular hole repair with 20, 23, and 25-gauge PPVsystems appears to be comparably effective in the improvementof final visual acuity, with an acceptable safety profile inall groups.
