title: Prolactinomas and the eye: a clinical case and review.
abstract: OBJECTIVE
  Elevated prolactin levels may have several etiologies, one of which is a prolactinoma. Prolactinomas, the most prevalent pituitary tumors, may be more common than once described. These tumors can result in ocular complications such as vision loss and visual field defects. Prolactinomas are easily treated but need to be identified early in order to prevent more serious systemic complications.
  
  
  METHODS
  A 24-year-old Pacific Islander male presented with sudden blurred vision and an associated visual field defect in the right eye for 4 to 6 months. After performing a magnetic resonance imaging and consultation with an endocrinologist, the patient was diagnosed with a prolactinoma. The patient was treated and demonstrated a complete recovery of visual acuity and visual field defect.
  
  
  CONCLUSIONS
  Prolactinomas are a common pituitary tumor characterized by an increase in prolactin levels. This review describes how prolactinomas are classified, their etiology, subsequent complications, and treatments.
