Case in brief
A 34-week-old infant admitted for repair of type C tracheoesophageal fistula with esophageal atresia and management of pelviectasis and low conus medullaris underwent routine retinopathy of prematurity screening. Investigational ultra-widefield optical coherence tomography incidentally showed a unilateral iris and peripapillary chorioretinal coloboma, alongside Zone III, Stage 0 retinopathy of prematurity. Imaging measured the coloboma excavation depth at 3.4 mm and axial length at 15.4 mm, yielding a relative excavation-to-axial-length ratio of 0.22, which suggested increased future retinal-detachment risk.
What made this case unusual
Ultra-widefield optical coherence tomography enabled geometric characterization of the coloboma, including a relative excavation-to-axial-length ratio that suggested increased retinal-detachment risk.
Diagnostic / clinical pearl
In an infant with VACTERL syndrome, ophthalmic screening may reveal iris and chorioretinal coloboma; ultra-widefield optical coherence tomography can characterize its dimensions.
