A case of proliferative vitreoretinopathy associated with morning glory syndrome

Background: The pathogenesis of retinal detachment associated with morning glory syndrome is unknown. Case Report: Proliferative vitreoretinopathy developed in the right eye of a 9-year-old girl. We performed pars plana vitrectomy to treat this condition. During the surgery, we found a lesion with the appearance of a retinal hole at the edge of the optic disc, but it was impossible to drain fluid from the lesion, so we made an intentional hole and drained subretinal fluid through it. With the thought that the origin of the subretinal fluid was leakage of fluid from within the optic nerve sheath, we performed endophthalmic laser photocoagulation for 360 degrees around the optic disc as well as the intentional hole, followed by an encircling procedure and injection of silicone oil. Silicone oil was later removed. There has been no recurrence of retinal detachment. Conclusion: We speculated that the pathogenesis of retinal detachment in this case was the influx of fluid from within the optic nerve sheath.
