Purpose: To report 2 cases of enlarged foveal avascular zone (FAZ) on optical coherence angiography (OCTA) imaging in pediatric patients with cutis marmorata telangiectatica congenita (CMTC). Observations: A 10-week-old female and a 3-year-old male diagnosed with CMTC presented for retinal examination. Both had peripheral avascularity on fluorescein angiography (FA) and enlargement of the FAZ on OCTA in both eyes. Conclusions and Importance: Pediatric patients with CMTC should undergo ocular evaluation with not only FA, but also OCTA to more robustly evaluate the affected retina in this rare disease.
