Pseudo optic disc duplication in association with posterior staphyloma

Abstract

We report a case of 67 years old female diagnosed with pseudo-duplication of the optic nerve in association with posterior staphyloma. Her best corrected visual acuity in the right eye was finger counting close to face and 6/9 in the left eye. The anterior segment findings were normal however in the left eye; a vertically oval and excavated lesion was present nasally, with vessels dipping in the excavation similar to the optic disc. SD OCT of the pseudo-disc in the left eye revealed an excavation corresponding to the pseudo-disc, whereas the right eye was normal. Orbit MRI did not reveal any true duplication of the optic nerve or associated pathology. The pseudo-optic disc does not require any treatment as it does not impair visual acuity and patients are usually asymptomatic.
