Macular hole diameter after vitrectomy for macular hole and retinal detachment.
OBJECTIVE
We measured postoperative macular hole (MH) size after vitrectomy for MH and retinal detachment (MHRD) in high myopia and investigated potentially associated factors.


METHODS
Eleven patients (11 eyes) with high myopia (axial length, 25.6-30.8 mm; mean patient age +/- SD, 64.0 +/- 4.31 years) who had retinal attachment without MH closure after vitrectomy for MHRD were included in the study. Postoperative MHs were measured using optical coherence tomography. A horizontal 5.65-mm-long scan of the retina was obtained, and the MH size was measured as the length between the edges of the MH using the retinal thickness mode of the optical coherence tomography system.


RESULTS
The mean postoperative MH size +/- SD was 1,220 +/- 450 microm. Only axial length was significantly associated with postoperative MH size (P < 0.05). There was a tendency for smaller MH sizes to be associated with better postoperative best-corrected visual acuity (P = 0.06).


CONCLUSIONS
Persistent MHs after vitrectomy were enlarged according to axial length elongation in highly myopic eyes. Even if MH closure was not successful, the maximum effort to shorten postoperative MH size led to a better postoperative outcome.
