To evaluate the clinical features and treatment outcomes of macular holes that developed in vitrectomized eyes.
Retrospective, interventional cases series
In this retrospective observational study, 44 vitrectomized eyes which had underwent repeat vitrectomy for macular hole were enrolled. We assessed clinical features including axial length, visual acuity, postoperative anatomical success, and compared according to preoperative axial length.
Macular hole occurred in 44 eyes in a mean of 13.8 months (range, 0.60 - 142 months) after initial vitrectomy. The macular holes closure rate in the longer axial length group (≥26mmA) was 47.6% (10 of 21 eyes), and significantly lower than 78.3% (18 of 23 eyes) in the shorter axial length group (<26mmA)(p<0.05). The mean best-corrected visual acuity was improved in eyes with hole closure (p <0.05). Also, the visual improvement was reversely correlated with the axial length in the longer axial length group (p < 0.05).
Repeat vitrectomy was able to achieve hole closure and visual improvement. However, eyes with the longer axial length had poor anatomic and functional outcome compared with eyes with the shorter axial length.
