Impact of smoking on choroidal microvasculature dropout in glaucoma: a cross-sectional study.

ABSTRACT:

Objective

To investigate the effect of smoking on choroidal microvasculature dropout (MvD) in glaucoma.

Design

Cross-sectional study.

Setting

Tertiary glaucoma centre.

Participants

223 eyes of 163 patients with primary open-angle glaucoma who had undergone imaging with optical coherence tomography angiography and completed a questionnaire on smoking from the Diagnostic Innovations in Glaucoma Study.

Primary outcome measures

Linear mixed-effects models were used to determine the effect of each parameter on MvD area and angular circumference. The sensitivity analysis was performed by categorising the glaucoma severity determined by visual field mean deviation (MD).

Results

MvD was found in 37 (51.4%) eyes with smoking history and in 67 (44.4%) eyes
