Abstract

Purpose: To assess the effect of chronic cigarette smoking on corneal and lens densitometry measurements using Pentacam HR and to compare the results obtained with those in non-smokers.

Materials and methods: This cross-sectional comparative study included 40 chronic-smokers and 40 age-matched healthy non-smokers between 18-40 years. After general ophthalmic examination, the Pentacam HR imaging system was used to evaluate corneal and lens densitometry measurements of smokers and non-smokers.

Results: The mean corneal densitometry values were not statistically significantly different in all the concentric zones and layers in the eyes of the smokers and non-smokers (p > 0.05, for all). However, the mean values of zone 1, zone 2, zone 3 and average lens densitometry measurements of the smokers were statistically significantly higher compared to non-smokers (p < 0.05, for all). Additionally, significant positive correlations were detected between the number of pack-years smoked and lens densitometry measurements.

Conclusion: Lens densitometry measurements of smokers were significantly increased while corneal densitometry measurements were not significantly altered compared to non-smokers. Smoking may contribute to cataractogenesis and smoking and age-related changes may act synergistically to cataract development among smokers.

吸烟对角膜和晶状体清晰度的影响：密度计分析。

目的：评估长期吸烟对Pentacam HR角膜和晶状体密度测量的影响，并将结果与非吸烟者的结果进行比较。材料和方法：这项横断面比较研究包括40名18-40岁的慢性吸烟者和40名年龄匹配的健康非吸烟者年。在一般眼科检查后，使用Pentacam HR成像系统评估吸烟者和非吸烟者的角膜和晶状体密度测量。结果：吸烟者和非吸烟者眼睛所有同心区域和同心层的平均角膜密度测量值没有统计学上的显著差异（p > 0.05）。然而，吸烟者的1区、2区、3区的平均值和平均晶状体密度测量值在统计学上显著高于非吸烟者（p 结论：与非吸烟者相比，吸烟者的晶状体密度测量值显著增加，而角膜密度测量值没有显著改变。吸烟可能有助于白内障的发生，吸烟和与年龄相关的变化可能对吸烟者的白内障发展起协同作用。

期刊介绍： Cutaneous and Ocular Toxicology is an international, peer-reviewed journal that covers all types of harm to cutaneous and ocular systems. Areas of particular interest include pharmaceutical and medical products; consumer, personal care, and household products; and issues in environmental and occupational exposures. In addition to original research papers, reviews and short communications are invited, as well as concise, relevant, and critical reviews of topics of contemporary significance.
