[Macular pathology as a cause of visual impairment?].

This article reports a case of a pituitary adenoma as the cause of unilateral visual impairment and concomitant unilateral macular pathology. Pituitary adenomas can be classified into hormone-secreting and inactive tumors of the adenohypophysis and lead to typical symptoms in cases of hypersecretion of hormones or hypopituitarism. A pituitary adenoma classically presents with bitemporal hemianopia when compression occurs at the optic chiasm. Imaging is crucial in diagnosing pituitary adenomas. Microsurgical or endoscopic transsphenoidal surgery, hormone therapy and radiotherapy are the treatment options.
