Morning Glory Disc Anomaly or Optic Disc Coloboma?

Morning Glory Disc Anomaly or Optic Disc Coloboma? Abstract In their case report in the April 1993 issue of the Archives, Dailey et al1 misinterpret the morning glory disc anomaly shown in Figure 1 as an optic disc coloboma. The stereoscopic photograph shows a large optic disc surrounded by an annular zone of retinal depigmentation, an elevated glial tuft overlying the center of the disc, and anomalous retinal vessels that arise from the periphery of the optic disc and extend radially over the peripapillary retina. These typical features of the morning glory disc anomaly differ from those of the optic disc coloboma in which there is a discrete, focal, glistening white, bowl-shaped excavation decentered inferiorly within an enlarged optic disc, and minimal, if any, pigmentary disturbance surrounding the disc.2 The importance of this distinction lies in the fact that optic disc colobomas are often familial, often accompanied by retinochoroidal or iris colobomas, and commonly associated with congenital References 1.
