IntroductionPituitary Adenomas make up 12–15% of symptomatic intracranial neoplasms. They may occur at any adult age, but are rare in childhood. Pituitary adenomas are the most common cause of chiasmal compression; the nonsecreting tumors typically present with visual loss, having reached a relatively large size without other symptoms; hormonally active tumors, on the other hand, are often detected prior to visual loss because of systemic symptoms related to hypersecretion.Aim and MethodsTo report a case of Pituitary Adenoma with description of clinical manifestations, investigative studies, management, and outcomes. A 51 year old male presented with LE progressive loss of VA over a 6 months period. RE VA: 20/20; LE VA: 20/30. The ophthalmological examination was unremarkable. Visual field testing showed RE temporal superior scotoma and LE temporal hemianopia. CT and MRI showed a 33 × 45 mm parasellar lesion with chiasmal compression. Trans-sphenoidal resection was performed.ResultsNull cell Pituitary Adenoma (nonsecreting tumor). VA and visual field defects recovery after surgery.DiscussionThe ophthalmologist's role in the management of these tumors is critical in that the first sign of recurrence may be visual loss. Periodic visual field and visual acuity testing and neuroimaging are essential.ConclusionOphthalmologists should be aware that VA loss may be associated with neurological lesions and with life threathning disease.
