Background: Reaction time is the elapsed time between presentation of a sensory stimulus and the subsequent behavioural response. Time taken to respond to visual stimulus gives visual reaction time. In the modern world, the usage of computers for occupational purpose is increasing with increased duration of usage, especially in IT profession. Few studies have been done on reaction time in mobile phone users and video game players, but no study is done in occupational computer users.
Objective: To compare visual reaction time between occupational computer users (use computer for work >40hrs/week) and the controls (recreational computer users : <15hrs/week)
Materials and Method: Study was done on 30 occupational computer users (use computer for work >40hrs/ week) and 30 recreational computer users (<15hrs/week) in the age group 20-35 years, after institutional ethical committee clearance and consent from all subjects. Visual Reaction Time was measured using Human Benchmark Software. Student’s t test was used for statistical analysis and p value <0.05 taken statistically significant.
Results: Results showed a statistically significant decrease in visual reaction time in occupational computer users with a p value of 0.01
Conclusion: Usage of computer for longer hours especially for occupational purpose decreases the visual reaction time in the individuals when compared with those who use it for lesser hours like recreational purpose.

Background: Type 2 diabetes mellitus a common endocrine disorder is on constant rise in the world. Diabetes mellitus is associated with premature mortality and several complications such as neuropathy, nephropathy and cardiovascular diseases. It can lead to decrease in psychomotor speed, executive functions, verbal memory, processing speed, complex motor functioning, working memory, visual retention and attention. These consequences have been attributed to glycemic control and duration of disease.
Objective: 1) To correlate duration of disease with attention, executive function and visual reaction time in type 2 diabetes patients.
2) To correlate HbA1c with attention, executive function and visual reaction time in type 2 diabetes patients.
Materials and Method: 60 uncomplicated Type 2 diabetes mellitus patients of either sex, aged 40-60 years were recruited from Diabetic Clinic Victoria Hospital, Bangalore. Ethical clearance & informed consent taken. After detailed examination & history taking, 2ml of fasting blood sample were taken for estimation of HbA1c. The cognitive tests include Digit vigilance test for attention, Stroop test for executive functions and visual reaction time using Human Benchmark software. Correlation was found using Pearson correlation, p value<0.05 taken as statistically significant.
Results: The Attention and executive function scores and visual reaction time are positively correlated with both duration of disease and HbA1c. Significant correlation is found with attention and Visual Reaction time with p value<0.05.
Conclusion: With progressive increase in the duration of disease and HbA1c levels there is decline in Attention and executive function & increase in Visual reaction time.
