A study of post-operative clinico-imaging status and visual outcome after idiopathic macular hole surgery with amniotic membrane plug.

Objective: The aim of this study was to determine the efficacy of hAM plug in the treatment of idiopathic macular hole and to see its post-operative visual improvement and anatomical apposition. Material and methods: 10 eyes of 10 patients who had idiopathic MH underwent a pars plana vitrectomy (PPV) with the hAM plug implanted in MH. The patients were followed up on 2nd day, 1st week, 3rd week, 6th week and 3rd month. Results: Final anatomical closure of MH was achieved in all the cases. BCVA improved from 0.91±0.11 logMAR to 0.28±0.06 logMAR after 3 months. No adverse event was documented in the specified period. Conclusion: hAM plug is an efficient method to treat and manage idiopathic MH with encouraging results both in terms of anatomical closure and visual acuity gain.
