Association of Secondhand Smoking Exposure With Choroidal Thinning in Children Aged 6 to 8 Years: The Hong Kong Children Eye Study.

ABSTRACT:

Importance

Secondhand smoking is a risk to adult ocular health, but its effect on children's ocular development is not known.

Objective

To assess the association between choroidal thickness and secondhand smoking exposure in children.

Design, setting, and participants

Children aged 6 to 8 years were consecutively recruited from January 2016 to July 2017 from the population-based Hong Kong Children Eye Study at the Chinese University of Hong Kong Eye Centre. All participants underwent detailed ophthalmic investigations.

History of secondhand smoking was obtained from a questionnaire. Multipl
