Atypical Form of Congenital Excavated Anomaly of the Optic Disc With Characteristics of Peripapillary Staphyloma and Morning Glory Anomaly

Abstract

We present a 51-year-old female with a unilateral congenital excavated optic disc
anomaly. After clinical examination and appropriate diagnostic procedures we
were unable to determine with certainty whether it is a morning glory anomaly or a
peripapillary staphyloma. The atypical fi nding was an optic disc with characteristics
of both states. The affected eye had almost normal visual acuity (0.9 Snellen chart),
which is a rare fi nding in congenital anomaly of the optic disc. Confocal scanning
laser ophthalmoscopy (Heidelberg Retina Tomograph, HRT 3.0) was not of diagnostic
value in comparison with optical coherence tomography (OCT).
