Background: Dry eye disease (DED) is an ocular surface disorder with several
causes leading to numerous manifestations. It is common among medical
students. Aim: This study assesses the associated risk factors and prevalence
of DED and how it is impacted by prolonged reading among Saudi
undergraduate senior medical students. Methods: A descriptive online selfadministered
questionnaire was distributed among undergraduate senior
medical students from the University of Jeddah, Saudi Arabia. Statistical
Package for the Social Sciences (SPSS) version 23 was utilized to analyze the
data. Results: A total of 121 participants completed the questionnaire. They
comprised 87 (71.9%) males and 34 (28.1%) females, with a male-to-female
ratio of 2.6:1. Their ages ranged from 20 to >25 years, with the majority (54.5%)
aged 20–22 years and 63 (52.1%) were fourth-year medical college students.
The results showed that 22 (18.2%) had mild DED (OSDI (Ocular Surface
Disease Index) score 13–22), 10 (8.3%) moderate DED (score 23–32), 45 (37.2%)
severe DED (score 33–100) and 44 (36.3%) had normal (0–12) OSDI scores. The
male gender, age (20–22 years) and fourth-year medical college were most
common with DED. Age group 23-24 was protective against DED
development with relative risk 0.264 (95% CI: 0.100-0.696, P =0.007). Smoking
and chronic disorders were not associated with DED development. Conclusion:
DED after prolonged reading is common especially severe degree. The male
gender, age group (20-22 years) and fourth-year medical students were the
most affected group. Age group 23-24 was protective against DED
development. Further studies need to be implemented to establish a
comprehensible relationship.
