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 finding 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 finding 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).
