Optic nerve cyst associated with optic disk pits

Purpose To report a case with two optic disk pits which were associated with an optic nerve cyst in the same eye.Methods Observational case report.Results A 47-year-old patient noted visual impairment in the right eye. On examination the best corrected visual acuity in the right eye was 20/80 and in the left eye was 20/20. Biomicroscopy revealed, in the right eye, a very pale optic disk with two optic disk pits without macular elevation. Magnetic resonance imaging (MRI) revealed a well circumscribed 6×6-mm² round cystic lesion within the right optic nerve sheath adjacent to the temporal aspect of the right optic nerve at its retrobulbar segment, which compressed and displaced the nerve.Conclusions In the case of an extremely pale optic disk with congenital pits and visual impairment without macular detachment, radiological examination is indicated in order to exclude the possibility of coexisting optic nerve anomalies.
