Abstract

Objective

Previous studies provided evidence that gadolinium can be found in the aqueous chamber (AC) of the eye several hours post injection (p.i.) of gadolinium-based contrast agents (GBCAs). This study aimed to investigate whether gadolinium can be detected promptly after injection of a macrocyclic GBCA on contrast-enhanced T1-weighted MRI in the AC of children.

Methods

This retrospective study encompassed MRI of 200 healthy eyes of children suffering from retinoblastoma of the contralateral eye. MRI was performed with an orbital coil with the children in a state of general anesthesia. Differences of signal intensity ratios (∆SIRs) of the AC to the lens were determined between pre and post contrast-enhanced T1-weighted images (Dotarem®, Guerbet, 0.1 ml/kg body weight, mean (standard deviation) p.i. time = 12:24 (± 2:31) min).

Results

A highly significant signal intensity increase was found in the AC of healthy eyes 12 min after GBCA injection (median ∆SIR (interquartile range) = + 0.08 (0.05–0.12), p < 0.0001). In addition, gadolinium enhancement showed a strong negative correlation with children’s age in multivariate analysis with adjustment for p.i. time (p < 0.0001).

Conclusions

GBCA leakage into the AC of healthy infantile eyes was found promptly after injection. The negative correlation between patient age and GBCA enhancement might be explained by a maturation process of the blood-aqueous barrier or Schlemm’s canal. Future studies should assess the duration and potential diagnostic applications as well as possible safety concerns of gadolinium presence in the AC.

Key Points

• Leakage of gadolinium-based contrast agent into the aqueous chamber of infantile eyes was found promptly after intravenous injection (p < 0.0001).
• Gadolinium enhancement of the anterior eye chamber was negatively correlated with the children’s age (p < 0.0001).
