Pituitary tumour mimicking glaucoma: Two case reports
Ali H; Shibeb JNeuro-Ophthalmology 2011; 35: 64
OBJECTIVES: To describe two cases of pituitary tumour presenting as normal tension glaucoma. METHODS: Case 1. A 71-year-old female presented to clinic after being referred by the opticians with a left visual field defect and suspected glaucoma. She described a 12 month history of a 'misty' left eye. On examination her visual acuity was 6/6 bilaterally and intra-ocular pressures were within normal limits. On the left an RAPD and cupped discs were noted. Visual field tests indicated severe constriction on the left. A diagnosis of normal tension glaucoma (NTG) was made and anti-glaucoma drops commenced. Case 2- A 66-year-old man presents with visual acuity of no-perception of light on right. He had central vision of 6/12 and narrow tunnel vision on the left. Intra-ocular pressures were within normal limits and cupped discs bilaterally. A diagnosis of NTG was made and commenced on anti-glaucoma medication. RESULTS: Case 1-MRI scan showed the presence of a sellar mass extending to the suprasellar region with compression on the left side of the optic chiasm. She has been referred for neurosurgical management. Case 2. Pituitary macroadenoma was diagnosed resulting in transcranial pituitary surgery. COMMENTS AND CONCLUSION: Although neuro-imaging for glaucoma patients is not routinely recommended, we feel that atypical cases should raise the suspicion of other pathology.
