| Sumario: | Iori Wada, Shigeo Yoshida, Yoshiyuki Kobayashi, Yedi Zhou, Keijiro Ishikawa, Shintaro Nakao, Toshio Hisatomi, Yasuhiro Ikeda, Tatsuro Ishibashi, Koh-hei Sonoda Department of Ophthalmology, Kyushu University Graduate School of Medical Sciences, Fukuoka, Japan Purpose: 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. Patients and methods: 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. Results: Sealing of the macular hole was noted in all eyes after surgery. BCVA improved significantly from 1 month after surgery (P<0.001). The MV score was significantly higher than the MH score before surgery (P<0.05) and improved significantly from 1 month after surgery (P<0.03). The MH score improved significantly at 6 months after surgery (P<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. Conclusion: 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. Keywords: macular hole, metamorphopsia, optical coherence tomography |
