Purpose
To evaluate the surgical results of macular hole (MH) in patients with high myopia treated with pars plana vitrectomy (PPV) leaving the internal limiting membrane (ILM) flap floating in vitreous fluid at the edge of the MH.
Methods
Nine highly myopic eyes with MH of nine consecutive patients who underwent PPV were retrospectively evaluated. Three eyes were accompanied by retinal detachment (RD). ILM peeling was performed around the MH and some part of the ILM flap was left attached to the edge of the MH. Further manipulation of the ILM flap to cover the MH was not performed. Fluid-gas exchange was performed to the retinal vessel arcade level. Patients maintained a face down position for 3 to 7 days postoperatively.
Results
Complete MH closure was confirmed using optical coherence tomography in all eyes and three eyes with RD showed reattachment of the retina after the initial surgery. Visual acuity significantly improved (P = 0.02) and no eyes experienced MH reopening or RD occurrence during the follow-up period of 8.33 ± 3.61 months after the surgery.
Conclusions
MH with or without RD in highly myopic eyes could be successfully treated with PPV leaving ILM flap floating in vitreous fluid at the edge of the MH. After the ILM peeling, further manipulation of the ILM flap to cover the MH would not be necessary for the treatment of MH in high myopia.
