A TITANIUM MACULAR BUCKLE IMPLANT DESIGNED FOR AN EASY PLACEMENT IN MYOPIC MACULAR HOLES.

PURPOSE

A new easy-to-place titanium macular buckle implant and the surgical technique for placing it in myopic macular holes are presented. A 60-year-old patient with pathologic myopia presented with macular holes in both eyes. The hole in the right eye was recurrent and long-standing since the initial diagnosis, which was over 5 years ago. He refused surgery for the better seeing left eye. The vision of the right eye was 20/200. The patient only wanted macular hole repair in the right eye if a macular buckle could be incorporated in the surgery.

METHODS

Because there was no commercially available macular buckle in the United States, a custom-made titanium buckle was designed and manufactured for this patient. In addition to the standard pars plana vitrectomy, internal limiting membrane peel, and gas tamponade, the titanium macular buckle was placed externally to provide indentation over the macula.

RESULTS

The titanium macular buckle provided approximately 1 mm of indentation, shortening the axial length from 28.88 mm to 27.94 mm. The macular hole was closed postoperatively. Postoperative best-corrected visual acuity was 20/200 at 1 month with no complications from the titanium macular buckle implant or the surgical technique. There was no improvement in the final visual acuity, which was attributed to foveal atrophy because of the long-standing nature of the macular hole.

CONCLUSION

This titanium macular buckle implant designed for an easy placement could be an invaluable addition for surgical success in myopic macular pathologies, including myopic macular holes.
