Combined phacoemulsification, 23-gauge pars plana vitrectomy with internal limiting membrane peeling and gas tamponade for patients with coexisting idiopathic macular hole and age-associated cataract.

Abstract

The aim of the present study was to assess the curative effect of combined phacoemulsification, 23-gauge pars plana vitrectomy with Brilliant blue G-assisted limiting membrane peeling and gas tamponade in patients with coexisting idiopathic macular hole (IMH) and age-associated cataract. A total of 21 consecutive patients (21 eyes) with coexisting IMH and age-associated cataract were enrolled in the study. All patients were treated by 23-gauge microincision vitrectomy with internal limiting membrane peeling, gas tamponade and combined phacoemulsification. The pre-operative MH diameter, MH index and best-corrected visual acuity (BCVA), as well as events of post-operative MH closure and complications were recorded and analyzed. Anatomic closure of the MH was achieved in 19 eyes (90.4%) with a single surgery. The LogMAR BCVA value at 1 month after surgery and the final follow-up visit was significantly lower than the baseline value (P=0.0036 and P=0.0015, respectively). A significant correlation was identified between the MH index and the post-operative LogMAR BCVA (r=0.869; P<0.001). The combined technique applied in the present study produced favorable anatomic and functional results for patients with coexisting IMH and age-associated cataracts. The pre-operative MH size measured by optical coherence tomography may serve as a predictive factor for the LogMAR BCVA value following MH surgery.
