Optical coherence tomography useful for evaluating ocular issues in ALGS

Posted on October 15, 2021

Ultra-widefield and anterior-segment optical coherence tomography (OCT) imaging are useful in identifying ocular abnormalities in patients with Alagille syndrome (ALGS), according to a case report.

Posterior embryotoxon, along with other ocular abnormalities, may help establish a clinical diagnosis in some patients with ALGS.

In this case report, a previously asymptomatic woman with a heterozygous pathogenic variant in the JAG1 gene underwent ultra-widefield and anterior-segment OCT which showed bilateral retinal thinning with increased choroidal hyperreflectivity in the areas of peripheral retinopathy and optic disc elevation and confirmed bilateral iris atrophy.
