To evaluate the role of convergence of full-thickness macular hole (FTMH) edges in surgery using the inverted internal limiting membrane (ILM) flap technique.
Samara Regional Clinical Ophthalmological Hospital named TI Eroshevsky
Group 1 (22 patients, 22 eyes) and Group 2 (28 patients, 28 eyes) included patients with stage 3 and 4 FTMH (according to the Gass classification) who underwent surgery using the inverted ILM flap technique. In the first group, the surgery was performed without convergence of macular hole edges, while the second group received similar technique but with margin convergence.
Following the surgery, 15 patients from Group 1 (68.2%) achieved complete hole closure with restoration of normal macular profile. In Group 2, the similar outcome was observed in 27 patients (96.4%). In Group 1, 5 patients (22.7%) achieved incomplete hourglass-shaped closure, while in 2 patients (9.1%) no closure occurred. In Group 2, incomplete hourglass-shaped closure was observed in 1 patient (3.6%). One month after the surgery, best corrected visual acuity (BCVA) increased significantly up to 0.21±0.14 (р<0.05) in Group 1 and up to 0.28±0.15 (р<0.05) in Group 2.
1. Convergence of FTMH edges in the inverted flap technique allows to achieve better anatomic outcomes, compared with other methods described in literature. 2. A trend towards improved best-corrected visual acuity is observed in patients who underwent surgery using the inverted ILM flap technique with convergence of macular hole edges.
