New study investigates correlation between imaging technologies for congenital corneal opacity

Posted on

Although swept-source anterior segment optical coherence tomography (AS-OCT) offers valuable preliminary data for assessing congenital corneal opacity (CCO), it may not consistently provide precise assessments in all cases, according to a study that highlights the importance of using ultrasound biomicroscopy (UBM) for definitive evaluation, particularly in cases where AS-OCT fails to provide detailed information.

The investigation included children with unilateral or bilateral CCO who underwent examination under anesthesia (EUA) along with AS-OCT imaging. A total of 22 eyes from 15 patients were analyzed.

Results indicated a significant correlation between AS-OCT and UBM findings in 82% of cases. However, in 18% of cases, AS-OCT failed to provide detailed information that UBM revealed. Phenotypes identified included Peters anomaly, congenital corneal staphyloma, coloboma, peripheral sclerocornea, and congenital primary aphakia.

The researchers emphasized that while AS-OCT offers valuable preliminary data, it may not consistently provide precise assessments in all cases, and therefore, UBM should be considered for definitive evaluation.
