Abstract

Purpose:

To identify the risk factors for the development of macular hole retinal detachment (MHRD) after vitrectomy without internal limiting membrane peeling for pathologic MF.

Methods:

We retrospectively reviewed the records of 131 eyes (115 patients) treated with vitrectomy for pathologic MF from 2009 to 2014. The best-corrected visual acuity (BCVA), refractive error, axial length, and spectral-domain optical coherence tomography findings were analyzed.

Results:

Postoperative MHRD developed in 7 eyes (5.3%). Between patients with or without secondary MHRD after vitrectomy, there were no significant differences in age, sex, axial length, preoperative BCVA, refractive error, lens status, and presence of posterior staphyloma. Spectral-domain optical coherence tomography showed all 7 eyes (100%) had foveal detachment, while only 47 patients (37.9%) of 124 eyes had foveal detachment (P = 0.004). There was no significant difference between preoperative and postoperative BCVA in the 7 eyes with MHRD. The postoperative BCVA in the 124 eyes without MHRD was significantly improved (P < 0.001). Among the 124 eyes, both preoperative and postoperative BCVA of eyes with foveal detachment was worse than the eyes without foveal detachment (P < 0.001, respectively).

Conclusion:

Preoperative foveal detachment is a risk factor for the development of MHRD after vitrectomy for pathologic MF.
