Rhegmatogenous retinal detachment in morning glory syndrome pathogenesis and treatment.

We report a case of morning glory syndrome with retinal detachment. A slit-like retinal break at the edge of the excavated disc anomaly provided a direct communication between the subretinal space and the vitreous cavity. Retinal reattachment and useful vision was achieved after a single procedure of vitrectomy and gas tamponade. We believe that identification of the retinal break, removal of epipapillary fibroglial tissue and its traction force, the avoidance of perfluorocarbon liquid and the appropriate use of long-acting gas as endotamponade, all contributed to the favorable outcome. This is more evidence supporting the rhegmatogenous theory of retinal detachment in morning glory syndrome. A literature review of the clinical presentations and treatments of similar cases is included.
