Treatment of retinal detachment associated with optic nerve head coloboma

摘要

Retinal detachments secondary to optic nerve head colobomas are notoriously difficult to repair. Numerous surgical approaches have been used, including (in various combinations) vitrectomy, limited laser to the optic nerve head margin, long-acting tampo-nade, peeling of the posterior cortical vitreous, and scleral buckling. Despite varied surgical approaches, most of these retinal detachments recur and lead to loss of vision in the affected eye, which is in contrast with the excellent results obtained for repair of a typical optic nerve head pit retinal detachment with the use of vitrectomy, fluid-gas exchange, and light application of laser along the temporal margin of the optic nerve for the extent of the optic pit, or more recently with vitrectomy and cortical vitreous peeling alone.
