Visual functions in congenital hemiplegia

Background: Cerebral lesions causing hemiplegia can affect the retrochiasmatical visual pathways. Objective: The aim of this study was to investigate visual function in children suffering from congenital hemiplegia. Methods: Twenty children (mean age: 5 yrs, 5 mo; SD: 2 Yrs II mo) underwent orthoptic and ophthalmological examinations, Visual acuity was assessed using the Acuity Card Procedure and standard optotypes, In addition, visual fields were assessed using conventional perimetry (Goldmann's perimeter or Peritest) or behavioral test (BEFIE test), Results: A remarkable finding was that 75% of the subjects showed a visual field defect, mainly homolateral to the hemiplegic side and contralateral to the (most extensive) cerebral lesions. Conclusion: Visual functions of children suffering from congenital hemiplegia should be routinely assessed, with particular attention to the visual field.
