• We report the results of vitreous surgery in seven eyes with retinal detachments caused by retinal breaks at the margin of, or within, a choroidal coloboma. All seven eyes (100%) were reattached; visual acuities in five (71%) of the seven eyes improved from preoperative levels. Vitrectomy was combined with air-fluid exchange and endodrainage through preexisting retinal breaks or planned retinotomies in all but one of the cases. Part or all of the rim of the choroidal coloboma in six eyes underwent endophotocoagulation. The two eyes that did not experience postoperative visual improvement underwent intraoperative endolaser treatment 360° around the optic nerve. If peripapillary endophotocoagulation is performed, especially through the papillomacular bundle, nerve fiber damage may occur and prevent visual recovery, despite retinal reattachment. For eyes with retinal detachment associated with choroidal colobomas involving the optic nerve, postoperative laser treatment through the papillomacular bundle may be preferable.
