Purpose

To evaluate the effects of smoking on retinal vessel caliper, anterior chamber parameters, intraocular pressures, central macular thickness, subfoveal choroidal thickness.

Setting/Venue

30 healthy non-smokers and 30 healthy smokers enrolled in the study from January and February 2018

Methods

Retinal vascular analysis [central retinal artery equivalent (CRAE), central retinal vein equivalent (CRVE), and artery-to-vein ratio (AVR)], anterior chamber depth (ACD), central corneal thickness (CCT), iridocorneal angle (ICA), limbus-limbus distance (LLD), central macular thickness (CMT), choroidal thickness (CT) were measured at baseline and 5, 30, 60, 120, and 180 minutes. The results were compared and a p-value lower than 0.05 was determined as significant.

Results

The mean age of healthy smokers was 28.40 ± 4.03 years and healthy non-smoker was 27.33 ± 3.93 (p = 0.145). Both groups consists of 15 male and 15 female. Mean smoking year was 11,85 ± 2,09 package/year. There was no statistically significant difference between two groups in parameters of baseline measurements (p> 0.05). In smokers; at 5th, 30th and 60th minutes in CT, CRAE, and CRVE, a statistically significant decrease were detected.

Conlusions

Smoking has immediate changes on retinal vascular caliper and choroidal thickness.
