摘要: Objective: Determine the effects of tobacco cigarette or sham placebo-smoking on pupil diameter. Subjects: Ten non-smokers and 10 smokers (all healthy, drug free adults) were studied while resting in a comfortable lounger. Methods: Tobacco abstained from smoking all subjects caffeine-containing products for at least 8 h prior to testing. The each smoked one cigarette, inhaled air through an unlit cigarette. Right diameter, heart rate, systolic diastolic blood pressure measured before after sham- tobacco-smoking subject. Pupil size was colored photograph taken with Polaroid camera equipped high-speed flash subject standardized, dimly lit quiet room. Results: There no significant difference baseline diameter between tobacco-smoking. After tobacco-smoking, both showed slight but statistically pupillary constriction. Conclusions: Shortly constriction greater than sham-smoking.
