Abstract

Tear fluid has a critical
role for the function of the refraction index of the light and the quality of the
image. The purpose of this study is to
compare tear fluid and ocular dominance in
patients with refractive errors. One
hundred three patients with mean age
of 35.63±14.95 who was referred to ophthalmology
service for refraction examination were
enrolled to the study. The
handedness and ocular dominance were determined by the Edinburgh hand
preference questionnaire and other tests. Visual acuity was tested by ophthalmological methods and Schirmer test
was administered in patients.

Our study was included
seventy-three female and thirty male patients. Right
hand-dominance was found as 94.1% and right eye dominance as 66.0%. Myopia was
higher in both right (-0.74±1.16D) and left eye (-0.68±1.01D) dominance.
There were statically negative correlation between hypermetropia degree
and tear volume in the left eye (p= 0.015; r = -0.240) there is a negative
non-statically correlation for the right eye (p=0.060; r= -0.186). There was no
correlation either between the myopia degree and tear fluid, eye dominance, tear
fluid.

The existence of a negative correlation between the
amounts of hypermetropia with tear fluid, suggesting that the evaluation of
tear fluid should be considered in clinical significance.
