Fovea-sparing internal limiting membrane peeling for myopic traction maculopathy

To investigate the effectiveness and safety of a new surgical technique of fovea-sparing internal limiting membrane (ILM) peeling for the treatment of foveal retinal detachments (RDs) in eyes with myopic traction maculopathy.

Retrospective, consecutive, interventional case series.

Forty-five eyes of 45 consecutive patients who underwent vitrectomy and ILM peeling for the treatment of a foveal RD attributable to myopic traction maculopathy were studied. The patients were divided into 2 groups by the area of ILM peeled: complete macular ILM peeled group (30 eyes) and fovea-sparing ILM peeled group (15 eyes). A gas tamponade was used in all of the eyes. The main outcome measures were the rate of development of a full-thickness macular hole (MH) and the best-corrected visual acuity (BCVA). All of the patients were followed for more than 6 months.

A full-thickness MH developed in 5 of 30 eyes (16.7%) in the complete ILM peeled group and in none of the 15 eyes in the fovea-sparing ILM peeled group. Postoperative OCT examination showed a contraction of the residual ILM on the fovea and reduction of the outer lamellar holes in the fovea-sparing ILM peeled group. The postoperative BCVA was significantly better than the preoperative BCVA in the fovea-sparing ILM peeled group (P = .04), but not in the complete ILM peeled group.

Fovea-sparing ILM peeling results in better visual and anatomic outcomes for the treatment of foveal RD attributable to myopic traction maculopathy. These were accomplished by reducing the development of a full-thickness MH.
