Abstract
OBJECTIVE
To describe the long-term anatomical and functional restoration observed in patients operated on for a large macular hole (MH) using different macular interposition techniques.
METHOD
Retrospective analysis of the results obtained in a series of 9 patients undergoing large MH surgery (≥450μm) performing 4 different macular interposition techniques: inverted internal limiting membrane flap in 4 cases, autotransplantation of internal limiting membrane in 2, amniotic membrane graft in 2, and autologous anterior capsule graft in one. The mean follow-up time was 11 months. Anatomically, the outcome measures explored were the restoration of the outer layers of the retina and the pattern of MH closure. The final visual acuity and visual quality were functionally assessed.
RESULTS
The restoration of the outer layers was partial in 6 cases. The macular closure rate was 100%, showing an incomplete pattern in 4 cases. Visual acuity improved in 7 patients, remaining stable in 2. Three cases showed an eccentric fixation pattern and/or metamorphopsia.
CONCLUSIONS
The development of new surgical techniques has increased the rate of macular closure in large MHs. However, the anatomical and functional restoration remains unpredictable. In this work, macular closure was achieved in all patients and a higher rate of complete closure using inverted internal limiting membrane flap. The restoration of the outer layers was more favorable in the groups in which internal limiting membrane had been used. Functional recovery was independent of the technique used.
