Abstract
Purpose :
To compare the surgical outcomes of epiretinal membrane (ERM) removal in high myopia with and without retinoschisis
Methods :
Medical records of 44 patients with high myopia (either a spherical equivalent ≤ -6.0 D or an axial length ≥ 26.5 mm) who underwent pars plana vitrectomy for ERM removal were reviewed retrospectively (20 eyes with retinoschisis and 24 eyes without retinoschisis). Patients with macular hole, subretinal fluid, or subfoveal geographic atrophy were excluded. The changes of visual acuity (VA) and central macular thickness (CMT) on OCT at six months after surgery were analyzed.
Results :
The mean preoperative logMAR VA was not significantly different between both groups (0.44 vs 0.49, P=0.600). While postoperative VA was significantly improved in each group, the visual improvement was the greater in patients without retinoshcisis compared to patients with retinoschisis (P = 0.020). Also, there was a negative correlation between preoperative CMT and vision improvement (P < 0.05).
Conclusions :
ERM removal resulted in significant visual improvements in eyes with high myopia regardless of the presence of retinoschisis. Early ERM removal before the occurrence of retinoschisis might lead to better visual improvement in eyes with high myopia.
