Purpose:
To explore corneal tomographic and densitometric parameters associated with subtle corneal alterations
in children with allergic conjunctivitis using the Pentacam AXL system.
Methods: This cross-sectional study included 64 eyes of 32
children with allergic conjunctivitis (Group 1) and 40 eyes of 20 age-
and sex-matched healthy controls (Group 2).
Only participants with spherical equivalent between +4.00 and –4.00
diopters and cylindrical values upto –2.00 D were included to minimize
refractive bias. Corneal keratometric, pachymetric, elevation, ectasia,
densitometric, and asphericity (Q value) parameters were obtained using the Pentacam
AXL (OCULUS Inc., Germany). Data were analyzed using IBM SPSS Statistics 28.0 (IBM
Corp., Chicago, IL, USA), and p<0.05 was considered statistically significant.
Results: No significant differences were found between groups in age, sex,
intraocular pressure, keratometric parameters (K1, K2, Kmax), pachymetry,
or elevation indices (p>0.05). Ectasiaindices, including ISV, IVA, KI, and CKI, were comparable. However, the mean Q value was significantly more negative in
theallergicgroup (p=0.03). Corneal densitometry values were also significantly higher across most corneal zones, indicating early microstructural alterations possibly related to allergic inflammation.
Conclusion: Children with allergic conjunctivitis demonstrate subtle but
measurable differences in corneal asphericity and corneal densitometry. These parameters may represent promising complementary indicators for the assessment of
early corneal alterations in pediatricocularallergy. Longitudinal studies are needed to clarify their clinical relevance and temporal behavior.
