Abstract
PRCIS Decreased superficial whole image capillary density was observed in open angle glaucoma (OAG) patients with high smoking intensity. PURPOSE To investigate the effects of smoking on optic nerve head capillary density measured by optical coherence tomography angiography in patients with OAG. METHODS In this retrospective cross-sectional study, perimetric and preperimetric glaucoma patients enrolled in the Diagnostic Innovations in Glaucoma Study (DIGS) with optical coherence tomography angiography follow-up were included. Univariable and multivariable linear mixed analysis were performed to determine the effects of different variables on the superficial whole image capillary density. RESULTS A total of 432 eyes of 271 glaucoma patients comprising 63 preperimetric (106 eyes) and 208 perimetric OAG (326 eyes) were included. A history of tobacco consumption was reported in 105 (38.8%). Among smokers, mean (95% confidence interval) smoking intensity was 12.8 (10.2, 15.5) pack-years. After adjusting for age, glaucoma severity and other confounders, each 10 pack-year increase in smoking intensity (95% confidence interval) was associated with -0.54 (-1.06, -0.02) % lower whole image capillary density ( P =0.041). CONCLUSIONS Smoking intensity is associated with reduced optic nerve vessel density in glaucoma.

Association of cigarette smoking with retinal capillary plexus: an optical coherence tomography angiography study. Acta Ophthalmol 2022; 100:e1479-e1488. [PMID: 35396902 DOI: 10.1111/aos.15157] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/16/2022] [Revised: 03/18/2022] [Accepted: 03/30/2022] [Indexed: 11/26/2022]
Abstract
PURPOSE To investigate the association between cigarette smoking and retinal capillary plexus (RCP) using optical coherence tomography angiography (OCTA) and to examine whether potential vascular risk factors could impact their association. METHODS This is a cross-sectional, community-based study. The Jidong Eye Cohort Study included participants aged ≥18 years in the Jidong community (Tangshan city, northern China) from August 2019 to January 2020. All participants underwent comprehensive ophthalmic examination and completed detailed smoking questionnaires. Retinal vessel density in the superficial and deep RCP was automatically measured using OCTA. RESULTS Of the 2598 participants included in the study, 2026 (78.0%) never smoked and 572 (22.0%) had a history of smoking (494 [19.0%] current smokers and 78 [3.0%] former smokers). The median (interquartile range) age was 41 (34-52) years for the non-smoking group and 45 (35-54.5) years for the smoking group. Multivariable analysis showed that smoking history is associated with a low deep RCP vessel density in the parafovea (β, -0.53; 95% confidence interval [CI], -0.82 to -0.24) and four quadrants. Increased smoking pack-years were associated with reduced deep RCP vessel density in the parafovea (p for trend <0.001) and four quadrants. The significant interaction between diabetes and smoking only was found for superficial RCP vessel density in the parafovea (p for interaction = 0.014) and four quadrants except for the temporal quadrants. CONCLUSIONS Cigarette smoking is an independent risk factor for reduced deep RCP vessel density. Our findings imply the potential detrimental effect of smoking on the occurrence of ocular diseases.

Association of cigarette smoking with retinal thickness and vascular structure in an elderly Chinese population. Photodiagnosis Photodyn Ther 2021; 36:102481. [PMID: 34403826 DOI: 10.1016/j.pdpdt.2021.102481] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/05/2021] [Revised: 07/20/2021] [Accepted: 08/09/2021] [Indexed: 12/20/2022]
Abstract
BACKGROUND To explore the association of cigarette smoking with retinal thickness and vascular structure in an elderly Chinese population. METHODS This cross-sectional study enrolled employees and retirees aged over 50 years at Tianjin University of Sport from October 2020 to December 2020. Information on smoking status and lifestyle was obtained using a detailed questionnaire. All participants underwent full ophthalmic examination. OCTA image was acquired. Vascular and the thickness parameters in central fovea and peripapillary parameters were automatically calculated. Multiple linear regression analyses were utilized to assess the association of smoking with retinal thickness and vascular structure after controlling potential confounders. RESULTS Compared with non-smoking adults, current smokers (β=-36.78; P = 0.01) and ever smokers (β=-35.45; P = 0.00) tended to have thinner macular fovea. Cigarettes daily, pack-years of smoking and CSI were negatively related to macular thickness (cigarettes daily: β=-1.43; pack-years: β=-14.73; CSI: β=-14.70), while they were positively associated with the circumference (cigarettes daily: β=0.03; pack-years: β=0.30; CSI: β=0.31) and the area of FAZ (cigarettes daily: β=0.01; pack-years: β=0.07). CONCLUSIONS Cigarette smoking seems associated with decreased macular fovea thickness and elevated circumference and area of the FAZ compared to non-smokers. Our data add to evidence of smoking on retinal thickness and the microvascular system in the macular area.
