Insights
Scanning laser polarimetry (GDx) is a viable tool for assessing retinal nerve fiber layer thickness in children aged 6-9. This study establishes normal GDx parameters for this pediatric population, aiding in early detection of potential vision issues.
Area of Science:
- Ophthalmology
- Pediatric Optometry
Background:
- The retinal nerve fiber layer (RNFL) is crucial for visual function.
- Establishing normative data for RNFL thickness in children is essential for early detection of ocular diseases.
Purpose of the Study:
- To create a normative database of Scanning Laser Polarimetry (GDx) parameters in children aged 6 to 9 years.
- To compare GDx results across different ages within this pediatric cohort.
Main Methods:
- Retinal nerve fiber layer thickness was measured using GDx in 116 school-aged children.
- Data were analyzed globally and by age to determine normal ranges.
Main Results:
- The global analysis yielded a mean TSNIT of 59.43 (CI 95%: 58.41-60.45).
- Superior and inferior averages were 71.35 (CI 95%: 69.99-72.70) and 70.08 (CI 95%: 68.71-71.45), respectively.
- Age-specific results were comparable to the global findings.
Conclusions:
- GDx is well-tolerated and requires minimal cooperation, making it suitable for pediatric use.
- GDx can provide objective data on RNFL development in children aged 6-9 years.
Purpose:
To establish a database of scanning laser polarimetry (GDx) parameters for children between 6 and 9 years of age and compare the results at each age.
Methods:
The retinal nerve layer thickness of 116 children from one school was evaluated with GDx and the results were analyzed for each age and for the entire group to determinate the normal range for that population.
Results:
In the global analysis of the software-derived GDx parameters, we obtained a TSNIT average of 59.43 (IC95% 58.41-60.45), a superior average of 71.35 (IC95% 69.99-72.70), an inferior average of 70.08 (IC95% 68.71-71.45), and a TSNIT Std. Deviation of 25.11 (IC95% 24.36-25.86). The results from the analysis for age were similar to the global results.
Conclusions:
Given the low level of cooperation required, GDx can be used without problem to study the retinal nerve fiber layer in 6-9-year-old children. GDx could provide objective information about the state of development of the retinal nerve fiber layer during this period of life.
