Abstract
Purpose :
To compare the treatment results of myopic traction maculopathy (MTM) according to international photographic classification
Methods :
35 eyes that underwent vitrectomy for MTM were preoperatively classified into five categories according to the international photographic classification for myopic maculopathy. For subgroup analysis, eyes were divided into low grade (category 0, 1) (n=15) and high grade (category 2, 3, 4) (n=20) group, and the best corrected visual acuity (BCVA) and anatomical structure were compared.
Results :
Mean follow up period was 32.03±6.85 months. Both low (P=0.012) and high (P=0.045) grade group showed visual acuity improvement after surgery but eyes with low grade group showed superior postoperative BCVA than eyes with high grade group (P=0.008). The odds ratio (OR) of postoperative BCVA <0.7 (decimal) was 21 for high grade group to low grade group (P=0.001). Mean axial length was significantly longer in high grade group (30.67 ± 1.48) than low grade group (27.66 ± 1.48) (P<0.0001). Spearman’s correlation analysis showed that axial length significantly correlated with category of pathologic myopia (rho=0.6836, P<0.0001).
Conclusions :
For MTM, vitrectomy can help vision improvement in both low and high grade myopia. But the postoperative BCVA was better in low grade myopia, and there was limitation in vision improvement in high grade myopia.
