title: [Familial binasal visual field contraction].
abstract: A 45-year-old heavy smoker was referred to the clinic for acute unilateral visual acuity reduction and irregular visual field constriction. An ischemic optic neuropathy with ipsilateral pit of the disc and medullated parapapillar nerve fibres was diagnosed. In spite of a normal fundus a visual field contraction in the upper nasal quadrant was found on the other eye. The son of the patient had bilateral crater-like holes of the disc with binasal visual field contraction. Similar visual field defects were found in the patient's daughter, with pseudopapilledema.
