Impact of Nicotine on Retinal Vascularization (TABARET)

Fondation Ophtalmologique Adolphe de Rothschild

Status: Completed

Details and patient eligibility

About

The main hypothesis is the nicotine is associated with a modification of retinal micro-vascularization.

Patients will be recruited during their ophthalmologic consultation at the Rothschild Foundation, an OCT-A will be realized and data relating to medical history, oral contraceptive intake and nicotine consumption via cigarette or e-cigarette data will be collected.

The objective is to seek an association between retinal vascular density and inhaled nicotine intake.
