Abstract
Objective:
The purpose of this study was to determine
the effect of smoking on intraocular pressure in individual with normal blood
pressure and to compare the smoking effects on intraocular pressure in smoker
and non-smoker.
Material
and Methods: A hospital based descriptive cross sectional
study was conducted at Aziz Fatimah Hospital Faisalabad including 480 patients
of age between 20-50 years. The person with normal visual acuity and normal
blood pressure were included in the study. After history taking and visual
acuity measurement Ophthalmoscopy was performed to evaluate different eye
conditions. After that the intraocular pressure of both eyes was measured by
using Goldman Applanation tonometer.
Results:
There were 192 (40%) patients of age 20-30
years, 160 (33.3%) patients of age 31-40 years of age, and 128 (26.6%) patients
of age 41-50 years. The percentage of the subjects who smoke 1-5 cigarettes per
day was 12.9% and for those who smoke 6-10 cigarettes per day was 37.08%. The
mean IOP of smoker’s right and left eye was 21.50+2.5 mmHg and 22.3+2.9 mmHg
respectively. The mean IOP of non-smokers right and left eyes was 15.99+1.8 mmHg
and 16.96+2.1 mmHg respectively.
Conclusion:
There was a highly significant association of
rise in intraocular pressure in smokers as compared to non-smoker. This study
also concludes that intraocular pressure increases more in smokers left eye as
compared to the left eye.
