Indian Journal of Clinical and Experimental Ophthalmology (IJCEO) is open access, a peer-reviewed medical journal, published quarterly, online, and in print, by the Innovative Education and Scientific Research Foundation (IESRF) since 2015. To fulfil our aim of rapid dissemination of knowledge, we publish articles ‘Ahead of Print’ on acceptance. In addition, the journal allows free access (Open Access) to its content, which is likely to attract more readers and citations of articles published in IJCEO.

Abstract
Introduction: Smoking tobacco is a risk factor for ocular disorders including dry eyes. This study
correlates dry eye tests among smokers and non-smokers, type of smoking and smoking load.
Materials and Methods: Dry eye tests were conducted on 80 smokers and 80 age matched non-smokers
after ethical approval and written informed consent.
Results: Smoker and non-smoker groups were comparable (Mean age: 48.98 and 49.03 years). All were
males. Majority of smokers belonged to the lower socioeconomic status and had outdoor professions.
Abnormal ities in dry eye scores (DEQ-5), corneal sensitivity, Schirmer’s 1 and 2, Tear film break up time
(TBUT) and corneal staining were significantly more among smokers (p<0>
eye score (9.75; 3.42), Schirmer’s 1 (18.95 ; 21.51mm), Schirmer’s 2 (19.16; 21.38 mm) and TBUT (8.47
; 12.26) were significantly more affected in smokers (p<0>
corneal sensation, Schirmer’s 1 and 2, and TBUT were significantly more in higher pack years (>40,000 )
than in lower (20,000 to 40,000) (p<0>
load. Abnormalities in tear meniscus height, corneal sensation, Schirmer’s 2 and TBUT were significantly
more among cigarette smokers (<0>
for abnormal test results with higher smoking load (Pack-years>40,000; R2 = 0.529). Severe corneal
staining showed goblet cell loss and squamous metaplasia, however this sample size was too small for
statistical inference.
Conclusion: Dry eye test abnormalities correlate significantly with smoking, higher smoking load and type
of smoking.
