abstract = "Purpose: To assess the prevalence and associations of small hard drusen in a child cohort.Methods: Cross-sectional study of 11- to 12-year-old Danish children from the population-based Copenhagen Child Cohort 2000 Eye Study. Fovea-centered, 45° color images of both eyes were graded for macular drusen (within one optic-disc-rim-to-fovea distance of the foveal center) and for extramacular drusen. Analyses tested for associations between drusen and anthropometric measures including choroidal thickness.Results: Gradable fundus images from both eyes were available for 1333 children (640 boys, 693 girls) with a mean (SD) age of 11.7 (0.40) years. One or more small hard macular drusen (diameter <63 μm) were present in 82 (6.2{\%}) right eyes and 82 (6.2{\%}) left eyes and in 147 (11.0{\%}) subjects. Four children (0.30{\%}) had 20 or more small hard macular drusen in one or both eyes. Extramacular small hard drusen were present in 10.7{\%} of children, and 19{\%} of children had such drusen anywhere. The odds for having one or more small hard macular drusen increased with subfoveal choroidal thickness with an odds ratio of 1.15 (95{\%} confidence interval, 1.03-1.28; P = 0.013) per 50-μm thicker choroid, adjusted for age and sex. The association with choroidal thickness was also present for extramacular drusen.Conclusions: Having one or more small hard macular drusen was common in 11- to 12-year old children and it was associated with a thicker subfoveal choroid. Few children had many small hard drusen. There is no apparent clinical impact of small hard drusen in childhood.",
