Insights
Premature children undergoing posthemorrhagic hydrocephalus surgery often experience visual impairments. Regular monitoring and visual support are crucial for managing these conditions in childhood.
Area of Science:
- Ophthalmology
- Pediatrics
- Neurology
Context:
- Premature infants are at risk for posthemorrhagic hydrocephalus.
- Surgical intervention for hydrocephalus can impact neurological development.
- Visual function assessment is critical in this high-risk pediatric population.
Purpose:
- To evaluate visual functions in children treated for posthemorrhagic hydrocephalus.
- To assess visual acuity, refractive errors, strabismus, and visual evoked potentials (VEP).
- To determine the long-term visual outcomes at 7-8 years of age.
Summary:
- 37.5% of children had normal visual acuity.
- 62.5% presented with refractive errors, primarily hyperopia.
- Strabismus was present in 62.5% of cases.
- All children exhibited pathological visual evoked potentials (VEP).
Impact:
- Highlights the high prevalence of visual deficits in this cohort.
- Underscores the necessity for regular ophthalmological follow-up.
- Emphasizes the need for visual handicap compensation strategies.
Unlabelled:
The aim of this study was to evaluate the visual functions in premature children, who had posthemorrhagic hydrocephalus surgery. The visual acuity, refractive error, strabismus, and evoked potentials of the optic nerve (VEP) were examined at the age 7 - 8 years of life. The normal visual acuity was found in 37.50% of children. The refractive error was found in 62.50% of patients. Hyperopia was found, and in the same percentage of cases the strabismus appeared. In all cases, the pathological VEP were found.
Conclusion:
From the results it is clear, that regular follow-up controls in premature children with posthemorrhagic hydrocephalus and compensation of their visual handicap are of necessity.
