| dc.description.abstract | Background: Global prevalence of myopia is increasing, and is predicted that
half of world population with have myopia in 2050. Myopia is caused by complex
interaction between genetic factor and environment factor. Contrast sensitivity is
an important additional test in assessing visual quality and detecting early visual
disturbance.
Objective: To find the correlation between myopia degree and axial length and
contrast sensitivity value in students at Faculty of Medicine University of
Sumatera Utara.
Methods: This was an analytic observational study with cross sectional design
done in Eye Clinic at University of Sumatera Utara General Hospital. Subjects of
the study is medical students in Faculty of Medicine University of Sumatera Utara
that had myopia who underwent refraction examination and contrast sensitivity
examination.
Results: From 70 study subjects, female subjects were more than male subjects.
Mean age of the subjects was 19.55 years old, with most visual acuity acquired
was 6/60. Most of the subjects were mild myopia, with mean axial length of 24.90
mm in the right eye and 24.88 in the left eye. Mean contrast sensitivity value was
1.94.
Conclusion: There was a significant correlation between myopia degree both in
the right eye (p<0,001, r= -0,511) and the left eye (p<0,001, r= -0,588). There was
a significant correlation between axial length and contrast sensitivity value both in
the right eye (p<0,001, r= -0,656) and the left eye (p<0,001, r= -0,640). | en_US |
