PURPOSE: Single umbilical artery (SUA) is the most common malformation of the umbilical cord. However, there have been no studies on the ocular findings in SUA, except for one case report. This study aimed to investigate the ocular findings in children with SUA. METHODS: Fourteen children (eight boys and six girls) with SUA were evaluated retrospectively. All children underwent a complete ophthalmologic examination. RESULTS: The prevalence of abnormal ocular findings in children was up to 42.9%. Refractive errors are detected in four eyes (14.3%): myopia > or =-1.50 diopters (D) in one eye (3.6%) and hyperopia > or =+2.00 D in three eyes (10.7%). Epiblepharon was found in three children (21.4%), and strabismus was detected in one child (7.1%). CONCLUSIONS: Approximately half of the children with SUA showed abnormal ocular findings, therefore, our case series highlight the need for a comprehensive ocular examination and larger prospective research studies in young patients with SUA.
