OCT in successful surgery of retinal detachment associated with optic nerve head pit

Abstract

The authors describe the course of a patient with retinal detachment associated with optic nerve head pit for whom optical coherence tomography (OCT) was performed before and after vitrectomy and gas tamponade. An 18-year-old woman presented with macular elevation and a lamellar macular hole associated with optic nerve head pit. OCT showed that the retinal elevation consisted of both separation of the inner and outer retinal layers and detachment of the outer layers from the retinal pigment epithelium. After vitreous surgery and postoperative intraocular gas tamponade, the macular elevation gradually resolved, and OCT showed that improvement in central vision corresponded with flattening of the outer layer detachment in the fovea. OCT is a useful tool for monitoring the therapeutic effect of vitrectomy and gas tamponade for retinal detachment associated with optic nerve head pit.
