PURPOSE
To describe the prevalence and risk factors associated with amblyogenic refractive error in children with Coats disease.
METHODS
The medical records of children (<18 years of age) with unilateral Coats disease treated at a single tertiary care center were retrospectively reviewed. Data collected included patient demographics, ocular examinations, and treatments. Outcomes included the prevalence and factors associated with amblyogenic refractive error.
RESULTS
A total of 50 children (82% male) were included; of these, 37 (74%) had refractive data to review. The median age at presentation was 5 years (IQR, 2-10). The Coats disease classification was stage 1 in 1 (2%), stage 2 in 29 (58%), and stage 3 or greater in 20 (40%). Most children (76%) had at least one visit with a pediatric specialist; the rest were only seen by a retina specialist. Among patients with refractive data, amblyogenic refractive error was identified in 46%. Glasses were prescribed to 50% of children. Children diagnosed at an earlier age had increased odds of amblyogenic refractive error (OR = 0.72; 95% CI, 0.57-0.91; P = 0.006) than those diagnosed at an older age.
CONCLUSIONS
Our results suggest that amblyogenic refractive error is prevalent among children with Coats disease, and refractions are not always performed. There is a need to coordinate care between pediatric and retina specialists caring for children with Coats disease to ensure timely diagnosis of amblyogenic refractive error to optimize visual outcomes in this population.
