Purpose
To report the clinical features, possible associations and treatment outcomes of patients with macular hole after pars plana vitrectomy (single or multiple) for rhegmatogenous retinal detachment.
Methods
Retrospective consecutive case series from July 2009 to July 2014.
Results
In the 15 study patients, the average time from retinal detachment surgery to macular hole diagnosis was 119 days (range: 41 – 398 months). Possible associations include epiretinal membrane (73%, 11/15 patients), macula-off retinal detachment (60%, 9/15 patients), recurrent retinal detachment (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 retinal detachment, possible associations were epiretinal membrane, macula-off retinal detachment, recurrent retinal detachment and high myopia. Even when macular hole closure was achieved, limited visual improvement occurred.
