Smoking Causes Eye Damage Similar to That Found in Glaucoma

Woman smoking.

Researchers in Turkey evaluated the effect of smoking on the retinal nerve fiber layer (RNFL), which collects visual impulses from photoreceptors (rods and cones) and ganglion cells in theretina and transmits these impulses to the optic nerve.

A total of 88 adults between the ages of 20 and 50 participated in the study: 44 had smoked at least one pack of cigarettes a day for more than 10 years, and 44 did not smoke. All were in good health, and there were no significant differences in age, sex distribution, refractive errors or eye pressure between the two groups.
