Abstract:
PURPOSE: To analyze the recovery course of foveal microstructures and evaluate the important structures for visual improvement after vitrectomy for full thickness macular hole (MH) using optical coherence tomography (OCT). METHODS: We retrospectively reviewed the medical records of 34 cases with idiopathic macular hole. We investigated the healing process of foveal microstructures and visual acuity pre- and post-operatively at 1, 3, 6, 12 months after surgery. We evaluated the integrity of four factors by OCT image: existence of MH (Hole, H(1,3,6,12)), recovery of outer nuclear layer (ONL, O(1,3,6,12)), recovery of external limiting membrane (ELM, E(1,3,6,12)), and recovery of inner segment-outer segment (IS/OS) line of the photoreceptor (Photoreceptor, P(1,3,6,12)). We compared the recovery course and visual acuity of the four groups based on postoperative 12 months. RESULTS: The mean observed period was 1.85 ± 2.59 months at recovery of ONL, 3.78 ± 3.83 months at recovery of ONL and ELM, and 7.40 ± 3.56 months at recovery of ONL, ELM and IS/OS line. At postoperative 12 months, the best corrected visual acuity (BCVA) of Groups E and P were better than that of Groups H and O (p < 0.05). Except for group H, all groups had improved BCVA at postoperative 12 months compared to preoperative BCVA (p < 0.05). CONCLUSIONS: Recovery sequences of foveal microstructures were ONL, ELM and IS/OS line after vitrectomy for idiopathic MH. The most important structures for visual acuity were restorations of both ELM and IS/OS line.
