Abstract :
Several studies have reported a high prevalence of
accommodative and vergence anomalies in the university
student’s population in different states of India. Their
findings were diverse owing to differences in diagnostic
techniques and the criteria used to define the variables.
Different type of influential factors and geographical
variation has also an impact on their variable result.
This current study is aimed to assess find the prevalence
of non-strabismic binocular vision disorder (NSBVD) in
a randomised population of college students in
Mangalore, India.
A randomized sample of 600 college students (300
males and 300 females), aged 18-23 years were included
in this cross-sectional study. To evaluate the prevalence
of NSBVD all the subjects undergone through a
comprehensive ophthalmic examination including visual
acuity testing, assessment of anterior and posterior
segment, assessment of ocular motility and binocular
vision.
Prevalence of NSBVD in college students is 76.5%.
Convergence insufficiency was the most prevalent
(27.5%) in college students followed by convergence
excess (24%) and Accommodative Insufficiency (22.5%)
among all type of NSBVD. Prevalence of NSBVD is more
in females than male.
Early detection of NSBVD is important because
without treatment these disorders may lead to
strabismus resulting in loss of stereopsis and
development of suppression. If any accommodative of
vergence disorder is found, then effective treatment
should be prescribed immediately. Timely identification
and proper treatment of NSBVD will allow a student to
performing at his or her full potential.
