Abstract

Purpose: To assess the macular hole (MH) closure rate and final visual acuity after idiopathic MH treatment with a modified fovea-sparing technique and 20% SF6 gas tamponade.

Material and Methods: Fifteen patients (16 eyes; 12 women and 3 men; mean age (standard deviation or SD), 65.5 (5.90 years)) with Gass stage 2 to stage 4 MHs were involved in the study. Before surgery, mean best-corrected visual acuity (BCVA) (SD) was 0.15 (0.09), and mean MH diameter (SD), 437.2 (164.7) µm. Patients underwent surgical treatment with the modified fovea-sparing technique and 20% SF6 gas tamponade of two-week duration and were instructed to maintain a face-down position for a week after surgery.

Results: At 1 month after the first surgery, MHs were closed in 11/16 eyes (68.75%). In addition, mean BCVA (SD) in eyes with closed MHs improved significantly from 0.15 (0.09) to 0.48 (0.16) (р = 0.000000). Of the five eyes in which the MH had failed to close after primary fovea-sparing surgery, two received a gas fluid exchange gas tamponade with 15% С3F8, and these patients were advised to maintain a face down position for 3 more weeks. In addition, in another two eyes, the vitreous cavity was revised, and the internal limiting membrane (ILM) was removed by a conventional technique with 15% С3F8 gas tamponade. Moreover, one patient rejected repeat intervention. In the four eyes in which the MH had failed to close after primary fovea-sparing surgery, after a repeat intervention, the MH was closed, and mean BCVA (SD) improved to 0.35 (0.04). There was no significant difference between the eyes in which the MH failed to close and the eyes in which the MH did close after primary surgery in terms of mean MH size (SD) (455 (203) µm versus 415 (155) µm, р = 0.66) or MH duration.

Conclusion: A long gas tamponade (longer than 1 week) is required to improve the closure rate with the fovea-sparing ILM peeling technique for idiopathic MHs.
