Two cases of glaucoma-associated empty sella turcica diagnosed by unusual visual field defects

Background: We report 2 cases of visual field defect caused by an empty sella turcica that was associated with glaucoma. Case Reports: Case 1 was an 82-year-old female with primary open-angle glaucoma that was being treated with eye drops. Humphrey automated perimetry showed binasal hemianopsia. The optic disc showed glaucomatous excavations, with a cup/disc (C/D) ratio of 90%. Magnetic resonance imaging (MRI) revealed an empty sella. Case 2 was a 62-year-old female with elevation of intraocular pressure that was being treated with eye drops. Goldmann perimetry showed a visual field defect that was not associated with optic disc changes. MRI revealed an empty sella. Because in both of these 2 cases intraocular pressure was elevated with typical glaucomatous optic disc and visual field changes, we diagnosed glaucoma with co-existing empty sella. Conclusion: Particular attention should be paid to the appearance of the optic disc and visual field defect in patients with glaucoma.
