A 2-year-old boy with bilateral optic nerve colobomas was noted to have a total rhegmatogenous retinal detachment in his left eye less than a week after a fall, for which he underwent immediate repair with pars plana vitrectomy, membranectomy, endolaser, and gas tamponade. Despite initial reattachment, a subsequent examination under anesthesia 8 months after repair revealed a recurrent retinal detachment emanating from the coloboma as a closed funnel, with prior endolaser scars on bare retinal pigment epithelium (Figure). Retinal detachments are a known complication of optic nerve head colobomas and can be challenging to repair successfully.1
