A 45-year-old man presented to the ophthalmology clinic with complaints of progressive vision loss over the past six months. He reported difficulty seeing objects on the outer sides of his visual field, often bumping into things while walking. On examination, his visual acuity was normal, but a visual field test revealed a loss of vision in the temporal halves of both eyes. The patient was diagnosed with a pituitary adenoma, a common cause of this type of visual field defect
