| Summary: |
The investigations were
carried out to determine the role (relationship) between
cigarettes smoking and incidence of new lens opacitates.
Study conducted in Medical University Gdansk from 1998
to 2000 year. Analysis included 401 individuals (age 70
years in 1998 year). They were free of lenses opacities
at the first eye examination. I devided my patients into
two groups:
group I – smokers 288 patients,
group II non- smokers – 113 patients.
Data on the smoking history of the subjects were
collected by personal interviews that were conducted in
1998 and updated in 2000 year. Lenses were determined by
grading standard slit lamp and retroillumination
photographs of the lens baseline and 3-years follow-up
examinations. Lens photographs were taken and graded for
presence and severity of cortical, nuclear and
subcapsular cataract. During 3 – years follow-up
cataract incidence among 100% participans – smokers were
confirmed. Among the 100% eyes with cataract (smokers
only), nuclear cataract was present in 65.9%.
Subcapsular changes were observed in 13.6% smokers.
These data provide support for the hypothesis that
cigarette smoking increases the risk of nuclear cataract
development. Compared with never smokers, current
smokers of 25 or more cigarettes per day had a
statistically significant increase in the risk of
cataract. The significant relationship of smoking with
lens opacities suggest an etiologic effect but we need
further investigations. |
