The Saved Foveal Flap Technique in Small Gauge Macular Hole Surgery by Su Hwan Lee, June-Gone Kim, South Korea


ABSTRACT

Purpose:

To present the anatomical and functional outcomes of hybrid 23-25 gauge pars plana vitrectomy with saved foveal flap technique in patients with stage 2 and stage 3 macular hole with foveal flap.

Methods:

A retrospective interventional case series of 10 eyes with stage 2 and stage 3 macular hole with foveal flap. In the saved foveal flap technique, foveal flap was preserved by careful separation of the posterior hyaloid membrane and peeling of the internal limiting membrane from the flap. Endotamponade with gas or silicone oil was then performed. Preoperative and postoperative visual acuity and spectral domain optical coherence tomography (SD-OCT) images were evaluated.

Results:

Six eyes had stage 2 macular holes and 4 eyes had stage 3 macular holes. The mean visual acuity improved from baseline 0.7 logMAR to 0.13 logMAR at the final follow-up. Macular hole closure with intact ellipsoid zone and external limiting membrane on SD-OCT images was observed in 9 cases. One eye showed just pinpoint defect of the ellipsoid zone.

Conclusions:

The saved foveal flap technique might improve both the functional and anatomic outcomes of vitrectomy for stage 2 or 3 macular holes with foveal flap.
