The purpose of this study was to determine the degree of metamorphopsia using M-CHARTS™ in patients with idiopathic macular hole before and after pars plana vitrectomy and internal limiting membrane (ILM) peeling.
The records of 22 eyes of 22 patients with a full-thickness macular hole who underwent pars plana vitrectomy and ILM peeling were reviewed. All patients underwent a complete ophthalmic examination including spectral-domain optical coherence tomography (OCT). Horizontal metamorphopsia (MH) and vertical metamorphopsia (MV) scores were determined using M-CHARTS at the same time. The time course of changes in metamorphopsia and the relationship between best-corrected visual acuity (BCVA) and OCT parameters were assessed.
Sealing of the macular hole was noted in all eyes after surgery. BCVA improved significantly from 1 month after surgery (<0.001). The MV score was significantly higher than the MH score before surgery (<0.05) and improved significantly from 1 month after surgery (<0.03). The MH score improved significantly at 6 months after surgery (<0.001). The postoperative MV and MH scores became closer to one another from 1 month after surgery. Moreover, the MV score was higher than the MH score at all postoperative assessments. There was a significant correlation between the MV and MH scores at all follow-up assessments. There was no significant correlation between BCVA and the MV or MH score at any follow-up assessment.
The satisfaction of the patients with macular hole after surgery cannot be necessarily measured by BCVA alone, because M-scores were not correlated to BCVA in postoperative evaluation. Therefore, evaluation of the MV and MH scores can be an independent treatment outcome in addition to BCVA.
本研究旨在确定特发性黄斑裂孔患者在玻璃体切割术联合内界膜（ILM）剥除术前、后的M-CHARTS™变形视程度。
回顾性分析22例接受玻璃体切割术联合ILM剥除术的全层黄斑裂孔患者的22只眼的病历。所有患者均接受了包括频域光学相干断层扫描（OCT）在内的全面眼科检查。同时使用M-CHARTS确定水平变形视（MH）和垂直变形视（MV）评分。评估变形视的时间变化过程以及最佳矫正视力（BCVA）与OCT参数之间的关系。
术后所有眼的黄斑裂孔均闭合。术后1个月起BCVA显著改善（<0.001）。术前MV评分显著高于MH评分（<0.05），术后1个月起显著改善（<0.03）。术后6个月MH评分显著改善（<0.001）。术后1个月起，术后MV和MH评分彼此更接近。此外，在所有术后评估中MV评分均高于MH评分。在所有随访评估中，MV和MH评分之间均存在显著相关性。在任何随访评估中，BCVA与MV或MH评分之间均无显著相关性。
黄斑裂孔患者术后的满意度不一定仅通过BCVA来衡量，因为在术后评估中M评分与BCVA不相关。因此，除BCVA外，评估MV和MH评分可作为独立的治疗结果。
