| Summary: | Introduction: Dry eye (keratoconjunctivitis sicca) is a common
disorder of the tear film having multifactorial aetiology. Nowa-days, a large portion of population is affected with Dry Eye
Disease (DED) because of substantial increase in usage of
computers and digital devices.
Aim: To evaluate the effect of varying durations of computer
usage on parameters of DED.
Materials and Methods: In this prospective study, total 120
participants were divided into two groups. Group I (n=58)
included participants who used computer daily for less than six
hours while group II (n=62) included those who used computer
for more than six hours daily. Routine eye examination was
done and dry eye parameters i.e., Ocular Surface Diseases
Index (OSDI), Schirmer Test (ST) and Tear Film Break Up Time
(TFBUT) were performed and analysed for any significant
difference between groups I and II using unpaired t-test. SPSS
16.0 was used and p-value <0.05 was considered as statistically
significant. Pearson’s correlation test was performed to analyse
correlation of OSDI score with TFBUT and ST values.
Results: Mean OSDI scores in group I and group II were
37.39±8.98 and 49.54±11.7 (p<0.001), respectively; while
TFBUT values were 10.19±2.27 seconds and 8.12±2.9 seconds
(p<0.001), respectively. ST values were 12.82±3.32 mm in
group I and 10.80±3.86 mm in group II (p=0.0027). Significant
inverse correlation between OSDI score and TFBUT values
was found in both group I (r=-0.557, p<0.001) and group
II (r=-0.439, p<0.001). Similarly, correlation of OSDI score
with ST values in group I (r=-0.787, p<0.001) and group II
(r=-0.320, p=0.011) was also inversely significant. On the basis of
OSDI score, 38 (65.5%) participants in group I and 54 (87.08%)
participants in group II had severe dry eye. According to TFBUT
values 12 (20.68%) participants in group I and 29 (46.77%)
participants in group II and as per ST values 17 (29.31%)
participants in group I and 30 (48.38%) participants in group II
had severe dry eye.
Conclusion: Usage of computer or digital displays more than
six hours per day is a potential cause for the development of
severe DED. |
