ABSTRACT
PURPOSE:
To evaluate the association between macular hole volume (MHV) and postoperative central macular thickness (CMT) using spectral-domain optical coherence tomography (SD-OCT).METHODS:
Thirty-three eyes of 30 patients with a large full-thickness idiopathic macular hole with or without vitreomacular traction who underwent surgical intervention were included in this cross-sectional study. Complete ophthalmological examination, including SD-OCT, was performed for all participants during the pre- and postoperative visits. MHV was preoperatively measured using SD-OCT, which captured the widest cross-sectional image of the hole. For normal distribution analysis of the data, the Kolmogorov-Smirnov test was performed, and for statistical analyses, chi-square, Student's t-test, Mann-Whitney U test, and Pearson's correlation coefficient test were performed.RESULTS:
Mean preoperative best-corrected visual acuity (BCVA) and MHV were found to be 0.99 ± 0.36 (range, 0.3-2.0) logMAR and 0.139 ± 0.076 (range, 0.004-0.318) mm3, respectively. Mean follow-up was 16.3 ± 14.3 (range, 3-50) months. No statistical correlations were found between MHV and postoperative BCVA (p=0.588) and between MHV and disease recurrence (p=0.544). A weak negative correlation existed between MHV and final CMT scores (p=0.04, r=-0.383).CONCLUSIONS:
Greater MHV was found to be weakly associated with lower postoperative CMT scores.
