Cement dust poses an occupational hazard causing respiratory (owing to its inhalation), dermatological, ocular and hematological problems. The purpose of the current study was to evaluate the effect of occupational exposure of cement dust on hematological parameters in construction workers. Apparently healthy sixty five (65) adult male construction workers aged 25-50 years participated in this study. Three (3.0) ml venous blood samples were collected from each participant for hematological analysis at two different time points, one at 8 AM and second at 4 PM at the end of work shift. Differences in means and test of significance were calculated using paired Student's t-test. The results revealed that post shift samples showed statistically significant increase (p<0.05) in mean total leukocyte count (TLC), lymphocyte %, monocyte % and eosinophil % and statistically significant decrease (p<0.05) in mean hemoglobin, red blood cell (RBC) count, packed cell volume (PCV) and platelet count. The present study confirms that hematological parameters are significantly effected in construction workers which may be attributed to the work atmosphere predominated with cement dust.

In today’s world computers are ubiquitous and found in different forms which can effect intraocular pressure (IOP). Present study was undertaken to find out effect of day-to-day exposure to computer screen on IOP in normal individuals. 70 individuals (who met the screening conditions and devoid of obvious ocular pathology and systemic diseases) had their IOP’s checked before and 4 hour after computer session on same day, all working in general day shift, involving reading English printed material. The results showed significant (p<0.005) increase with IOP values before exposure being 17.89±3.25 and 16.99±2.84 and after exposure being 19.67±3.4 and 18.70±2.4 in left and right eye respectively. Increase in IOP was noted in 70% and 67% individuals in left and right eye. Differences in IOP of right and left eye may be due to dominance of eye or direction of script from left to right.

Objectives: The objective of this study were to find out differences in intraocular pressure (IOP) before and after computer usage and to find out differences in IOP in males and females. Computers have become such a vital part of our daily lives that it is often difficult for us to eliminate our use. The present age is regarded as the computer age. Most of our time goes looking at screens of different forms in laptops, desktop computers, tablets, and mobile phones. Computers use has become a necessity of the present-day world in various professions and it may sometimes require prolonged sessions which can produce strain on the eyes, liable to affect IOP. Methods: The present study includes 100 subjects between 20 and 40 years of age who works continuously for at least 4 h a day on computer screens and individuals without ophthalmological disorders. Schiotz tonometer was used to measure IOP by an ophthalmologist. Results: Our study sample contains 80% males and 20% females, with a manage of 29.29 and 27.55 years, respectively. The increase in IOP value of the left eye after exposure is comparatively more significant in the 6–10 years exposure group (p=0.0000). This finding is similar to the one obtained for the right eye. There is a significant increase in mean IOP values after computer exposure in both males and females. However, the increase is comparatively more significant in males compared to females. Conclusion: There will be a significant increase in IOP after Computer exposure in both genders with a comparatively greater rise of IOP in males than those in females.
