Abstract

A 26-year-old female presented with a persistent headache for 6 months. She had no other endocrinological abnormalities or any previous interventions.. Her best corrected visual acuity was 6/6. Colour vision and pupil reaction were all normal. Slit lamp biomicroscopy showed normal anterior and posterior segment examinations. Humphrey Field analysis 30-2 exhibited an enlarged blind spot with constriction of the superior visual fields in both the eyes. Magnetic Resonance Imaging(MRI) scan of the brain revealed a T2 hyperintense kinked optic chiasma with intrasellar herniation . She was diagnosed with optic chiasmal herniation due to primary empty sella syndrome and advised conservative management. Empty sella syndrome is characterized by the flattening or shrinkage of the pituitary gland. Primary empty sella syndrome arises without any prior pituitary pathologies, while secondary empty sella syndrome is linked to post medical, surgical, or radiation treatment of pituitary pathologies.
