Retinal detachment associated with optic disc colobomas and morning glory syndrome.

We report the diagnosis and treatment of patients with retinal detachment and/or retinoschisis associated with optic nerve coloboma or morning glory syndrome. A retrospective review of patients with optic nerve coloboma or morning glory syndrome with associated retinal detachment or retinoschisis was conducted. For five patients (six eyes), we report the clinical findings, spectral domain optical coherence tomography (OCT) imaging, intraoperative findings, and treatment outcomes. OCT scans demonstrate a bilaminar structure of maculopathy, consisting of inner schisis-like changes and outer layer retinal detachment. In most cases, a retinal break was demonstrated within the optic disc defect with three-dimensional OCT imaging. Glial tissue was sometimes observed within the anomalous defect. Vitrectomy and resection of the tractional tissue in these cases produced good anatomical and visual outcomes. Retinal detachment spontaneously resolved in cases where traction was not present. Traction may contribute to the pathogenesis of retinal detachment associated with colobomatous optic disc anomalies, either directly or by creating a secondary retinal break. OCT imaging assists with understanding the contributing factors to retinal detachment in individual cases of colobomatous optic disc anomalies and can thereby assist with determining the most effective approach to management.
