Abstract
Purpose
To describe the outcomes of fovea-sparing internal limiting membrane peeling for idiopathic macular holes.
Method
This was a prospective, interventional case series in patients with idiopathic macular holes. Patients underwent fovea-sparing internal limiting membrane (ILM) peeling with the help of a finesse loop. The primary outcome measure was successful anatomical closure. Secondary outcome measures were postoperative improvement in best corrected visual acuity (BCVA) or any surgical complications.
Results
The study included 22 eyes of 22 patients (median age of 61 (IQR 58 to 66) years). The median basal diameter of the holes was 1054 (IQR 961.5 to 1278) microns, while the median minimal linear diameter was 697 (IQR 461.5 to 786) microns. Successful anatomic closure was achieved in nine cases out of 22 (40.9%). BCVA improved from 20/125 preoperatively to 20/80 at the end of the follow-up. There was no difference in baseline parameters between eyes with closure, versus eyes with an open hole. One eye had an iatrogenic break in an attempt to reinitiate peeling and create a fovea-sparing flap. One of the eyes had an ERM formation at end of 3 months.
Conclusion
Our outcomes of fovea-sparing ILM peeling in idiopathic macular holes were unfavourable. The residual ILM could be causing tangential traction resulting in non-closure.
