Prenatal and childhood exposure to smoking and retinal nerve fibre layer thickness: A meta‐analysis of three independent birth cohorts

Puntos clave

• The study aims to examine the impact of prenatal and childhood exposure to smoking on retinal nerve fibre layer thickness.
• Conducted a meta-analysis of three independent birth cohorts.
• Evaluated the association between prenatal smoking and retinal nerve fibre layer thickness.
• Analyzed both global and sectoral changes in RNFL.
• Prenatal smoking is linked to reduced thickness in the retinal nerve fibre layer.
• Both global and sectoral deficits in RNFL were observed after exposure to prenatal smoking.
