Summary
Swedish Interactive Thresholding Algorithm Fast (SITA Fast) visual fields (VFs) are reliable for children aged 4 and older with idiopathic intracranial hypertension (IIH). A child-oriented program improves outcomes by shortening testing time.
Area of Science:
- Ophthalmology
- Pediatric Neurology
- Neuro-ophthalmology
Background:
- Idiopathic intracranial hypertension (IIH) can affect children, necessitating reliable visual field (VF) testing for monitoring.
- Assessing visual function in prepubertal children with IIH presents unique challenges due to age and cooperation.
- Swedish Interactive Thresholding Algorithm Fast (SITA Fast) offers a potentially quicker method for VF testing.
Purpose of the Study:
- To evaluate the reliability of SITA Fast visual field tests in prepubertal children diagnosed with idiopathic intracranial hypertension (IIH).
- To determine if factors such as age, gender, or the severity of visual impairment influence the reliability of SITA Fast VF tests.
- To compare the testing duration of SITA Fast with the Fastpac strategy.
Main Methods:
- A prospective, longitudinal cohort study was conducted involving 26 prepubertal children (<11 years) with IIH.
- Children underwent SITA Fast visual field testing as part of a child-oriented follow-up program.
- Statistical analyses, including ANOVA, point-biserial correlation, and chi-square tests, were used to correlate test reliability with age, gender, and visual outcome severity.
Main Results:
- SITA Fast VF tests were found to be reliable in children as young as 4 years old.
- Test duration for SITA Fast averaged 4.5 minutes per eye, significantly shorter than the 8 minutes for Fastpac.
- Reliability was not significantly associated with age, gender, or the severity of visual outcome.
Conclusions:
- SITA Fast visual field testing is a reliable and time-efficient method for assessing visual function in prepubertal children with IIH, starting from age 4.
- A child-oriented follow-up program incorporating shortened testing times may enhance outcomes for this patient group.
- Early implementation of reliable VF testing aids in managing visual deficits associated with IIH in children.
