title: Visual field defects in children with congenital glaucoma.
abstract: OBJECTIVE
  To determine visual field defects in a cohort of children with congenital glaucoma.
  
  
  METHODS
  Monocular visual fields were measured in 24 meridians for targets V4e, I4e, I2e, and I1e, using a Goldmann perimeter in a group of 13 children between the ages of 4 and 14 years with congenital glaucoma and 10 age-matched healthy children. Localized visual field defects (eg, paracentral scotoma, nasal step, and arcuate scotoma) were determined by abnormal findings or shape of the eye in at least one of each of the targets presented.
  
  
  RESULTS
  Visual field extent for target 12e was significantly constricted for unilateral and bilateral cases of congenital glaucoma when compared with control eyes. A post-hoc procedure (Tukey Test) showed significant differences between unilateral cases and normal control eyes, and between bilateral cases (best outcome eye) and normal control eyes. Stimuli V4e and 14e results were comparable for patients and normals. Stimulus I1e showed significantly different total extent visual field for bilateral and normal controls. Specific visual field defects were found only in bilateral cases. Paracentral scotoma was found in 1 of 12 eyes with bilateral congenital glaucoma. Nasal steps were found in 6 of 12 eyes with bilateral congenital glaucoma. Arcuate scotoma were found in 4 of 12 eyes with bilateral congenital glaucoma.
  
  
  CONCLUSIONS
  Localized visual fields were found in 37.5% of eyes with congenital glaucoma. Early treatment for congenital glaucoma provided better visual field outcome.
