Maternal smoking status was categorised by trimester of exposure and infants were followed for 3 years. Diagnoses were identified using International Classification of Diseases, Ninth Revision (ICD-9) codes and grouped into five categories: strabismus, refractive errors, congenital anomalies, inflammatory and infectious diseases and ocular tumours. Multivariable logistic regression was adjusted for infant gender, ethnicity, socioeconomic status, birth weight, gestational age and maternal age.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Among 50\u2009778 infants, 2830 (5.6%) were exposed to maternal smoking during pregnancy. Exposure was associated with increased risk of any ophthalmic condition (adjusted OR 1.15, 95%\u2009CI 1.04 to 1.26, p=0.004), strabismus (adjusted OR 1.34, 95%\u2009CI 1.06 to 1.69, p=0.013) and inflammatory and infectious diseases (adjusted OR 1.13, 95%\u2009CI 1.03 to 1.24, p=0.012). First-trimester exposure showed stronger associations with any ophthalmic condition (adjusted OR 1.16, 95%\u2009CI 1.01 to 1.33, p=0.034) and strabismus (adjusted OR 1.52, 95%\u2009CI 1.12 to 2.07, p=0.008). Exposure throughout pregnancy showed the strongest associations with any ophthalmic condition (adjusted OR 1.75, 95%\u2009CI 1.19 to 2.57, p=0.005), congenital anomalies (adjusted OR 1.85, 95%\u2009CI 1.01 to 3.37, p=0.045) and inflammatory\/infectious diseases (adjusted OR 1.81, 95%\u2009CI 1.24 to 2.63, p=0.002).
