Abstract

Vertigo, with or without nystagmus, may accompany many diseases. Most causes are transient and benign. A systematic approach saves valuable time. Nonrotational dizziness must be distinguished from true vertigo in which a sensation of motion is involved. Careful evaluation of nystagmus is essential, as is a complete cardiovascular examination. Meniere's syndrome, while common, is overdiagnosed.

Development of object vision in infants with permanent cortical visual impairment.

We examined 30 infants in whom cortical visual impairment was diagnosed during their first year of life to ascertain prognostic factors for the development of object vision, defined as the ability to recognize faces or hand-held toys. All patients were followed up for a minimum of 12 months. The most common causes of cortical visual impairment in the 30 infants were hydrocephalus in nine infants (30.0%), birth asphyxia or neonatal hypoxia in eight infants (26.7%), intracranial hemorrhage with or without hydrocephalus in seven infants (23.3%), and meningitis in five infants (16.7%). Lack of development of object vision was associated only with hypoxia (P = .013). Findings on ophthalmic examination, an abnormality in the visual pathway on computed tomographic or magnetic resonance scan, and seizures, hydrocephalus, intracranial hemorrhage, meningitis, cerebral palsy, developmental delay, prematurity, microcephaly, and hearing deficit, did not appear to be risk factors for the lack of development of object vision.
