title: [Visual fields defect as inicial presentation of neurosarcoidosis].
abstract: METHODS
  A 29 year old man who suffered from progressive loss of peripherical vision in the previous few weeks. He was being studied for hormonal dysfunction. The visual field showed superior arciform defect in the right eye and a superior altitudinal defect in the left eye. The endocrinology study showed hypopituitarism secondary to a neurosarcoidosis.
  
  
  CONCLUSIONS
  Neurosarcoidosis is very rare, and can produce irreversible visual fields defects. Prompt diagnosis and treatment are essential to maintain visual function.
