Morning Glory Syndrome and the Role of 3D OCT in Its Management

MGS is an uncommon congenital optic disc anomaly, which was first described by Kindler [1]. It is characterized by an enlarged funnel-shaped dysplastic disc with glial tissue. The retinal vessels are increased in number, appear to arise from the disc edge and run an abnormally straight course over the peripapillary retina [2,3]. Retinal detachment may occur in about one-third of cases of MGS [4,5]. The retinal detachments can be associated with slit-like retinal break at the edge of the excavated anomalous disc [6] or a retinal hole in tissue lying within the optic cup [7-9]. These provide a fluid pathway between the vitreous cavity and the subretinal space. In such a situation an OCT especially 3D is highly beneficial [9-11]. In this case the 3D OCT of the anomalous disc confirmed there were no predisposing factors for a retinal detachment and the patient was not at risk of developing retinal detachment.
