Abstract

Purpose:

To report a series of full-thickness macular holes (MH) that developed after pars plana vitrectomy for rhegmatogenous retinal detachment (RRD).

Methods:

A retrospective review of the demographic and medical data, including optical coherence tomography studies of 6 patients (7 eyes) who underwent pars plana vitrectomy for RRD and subsequently developed MH.

Results:

There were 4 women and 2 men with a mean age of 60 ± 10 years (range, 50–79 years). The mean interval between RRD repair and MH formation was 20 ± 18 months (range, 1–48 years). Five eyes underwent surgery to repair the MHs, four of which were closed at the last follow-up. Two eyes were not operated, one because of unfavorable prognosis, and in the other, which presented with an epiretinal membrane before the development of the MH, the hole closed spontaneously. In all operated cases, the inner limiting membrane was peeled during MH surgery. The mean logarithm of the minimal angle of resolution was 0.73, 0.53, 0.77, and 0.57 at RRD presentation, after surgical repair of RRD and before MH diagnosis, at MH presentation, and at last follow-up, respectively. The study subjects accounted for 1.1% of our 609 patients who underwent pars plana vitrectomy for primary RRD during the study period.

Conclusion:

Macular hole may develop after pars plana vitrectomy for RRD, and these cases can be surgically repaired. The pathogenesis of the formation of these holes remains unclear.
