Insights
Keratometry measurements can identify fetal alcohol syndrome (FAS). Horizontal keratometry readings of 46.00 diopters or higher serve as an objective marker for FAS, aiding in diagnosis and screening.
Area of Science:
- Ophthalmology
- Pediatrics
- Public Health
Background:
- Fetal alcohol syndrome (FAS) is a spectrum of disorders.
- Objective diagnostic markers for FAS are needed.
- Ocular abnormalities are common in FAS.
Purpose of the Study:
- To investigate the utility of keratometry in identifying children with FAS.
- To determine if specific keratometric values can serve as an objective landmark for FAS.
Main Methods:
- Keratometry was performed on 30 children diagnosed with FAS or fetal alcohol effects (FAE).
- Horizontal keratometric measurements were analyzed.
- Data was correlated with FAS/FAE diagnoses.
Main Results:
- Horizontal keratometric measurements of 46.00 diopters or greater were identified as a potential objective landmark for FAS.
- This finding suggests a correlation between specific corneal curvature and FAS.
Conclusions:
- Keratometry is recommended as a routine diagnostic test for children with suspected FAS.
- Keratometry may have value in screening the general school population for FAS.
Abstract:
Keratometry was performed on 30 fetal alcohol syndrome (FAS) and fetal alcohol effect (FAE) children. Horizontal keratometric measurements that are 46.00 diopters or greater appear to be an objective landmark of FAS. Keratometry is recommended as a routine test in evaluating suspected FAS children and appears to have value in screening the general school population for FAS.
