Abstract. Purpose:To report a case of pituitary apoplexy with unilateral inferior quadrantanopia as the initial manifestation. Case:A 50-year-old male presented with headache,impaired visual acuity and blepharoptosis in the left eye since the day before. Findings:Corrected visual acuity was 1.0 right and 0.2 left. The left eye showed blepharoptosis,restricted adduction and upward gaze. There were no abnormal findings in the eyeglobe in either eye. Goldmann perimetry showed findings simulating quadrantanopia in the lower nasal sector in the left eye. Magnetic resonance imaging(MRI)showed a tumor superior to the sella turcica compressing the optic nerve and chiasm upwards. The findings led to the diagnosis of pituitary apoplexy. Surgery was followed by normalized visual field with visual acuity of 1.0. Findings of oculomotor palsy disappeared. Conclusion:Unilateral quadrantanopia appears to have been caused by pituitary tumor with intratumor hemorrhage,or pituitary apoplexy,that compressed the posterior portion of optic chiasm upwards.
