Abstract

Purpose:

To report the clinical features, possible associations and treatment outcomes of patients with macular hole after pars plana vitrectomy (PPV) (single or multiple) for rhegmatogenous retinal detachment (RD).

Methods:

Retrospective consecutive case series from July 2009 to July 2014.

Results:

In the 15 study patients, the average time from RD surgery to macular hole diagnosis was 119 days (range: 41–398 months). Possible associations include epiretinal membrane (73%, 11/15 patients), macula-off RD (60%, 9/15 patients), recurrent RD (47%, 7/15 patients), and high myopia (56%, 5/9 patients). Single surgery was successful in hole closure in 8/15 patients (Group A) while 7/15 patients underwent multiple surgeries (Group B). Macular hole closure was achieved in 7/8 (87.5%) patients in Group A compared to 4/7 (57.1%) patients in Group B. Improvement of at least two lines of Snellen's visual acuity was achieved in 4/8 (50.0%) and 4/7 (57.1%) patients in Group A and B, respectively.

Conclusion:

In patients with macular hole formation after pars plana vitrectomy for RD, possible associations were epiretinal membrane, macula-off RD, recurrent RD, and high myopia. Even when macular hole closure was achieved, limited visual improvement occurred.
