wareness of poor visual acuity that can be treated easily
and effectively in the student groups can add positively
for their quality of life and quality of their study
Study design and test sample:
a descriptive cross-sectional
study done among students aged 14–19 years in secondary
schools in sulaimani city from six secondary schools both
male and female are enrolled
Aimand objectives:
to determine the prevalence and pattern
of refractive errors in this students group and determine
the prevalence of different types of refractive errors which
include (myopia, hypermetropia & astigmatism),
Subjects and methods:
the total of 848 students aged
14–19 years, were examined. Examination included visual
acuity testing by e chart, and refraction was done for those
having visual acuity less than 6/6. The refractive errors of the
students’ eyes were measured using streak self -luminous
retinoscopy and non-cycloplegic auto-refraction
Results:
out of 848 students, 737 (86.9%) were emmetropic
(normal visual acuity) and 111 (13.1%) were ametropic. Of
those 111 students, myopia with myopic astigmatism was
the commonest types: 41(36.9%), and 52(46.8%) students
respectively. Hypermetropia found in 14(12.6%) students.
Anisometropia was found in seven (6.3%) students,
represents (0.8%) of the sample. Amblyopia was found in
11(10%) students, of overall sample (1.3%) had amblyopia.
Only one had bilateral amblyopia. Bilateral vision correction
to 6/6 was found in 81(73%) students, (9.6%) of the study
sample, six (5.4%) students (0.7%) had unilateral correction
to 6/6, nine (8.1%) students (1.1%) had bilateral correction
to 6/9, and 15(13.50%) students, overall represents (1.8%) of
them, their vision was correctable to less than 6/12. Those
having glasses earlier were 35(31.50%) students represent
(4.1%) of the sample while 76(68.50%) student need glasses.
Conclusion:
prevalence of refractive errors was 13.1% of the
sample. Simple myopia was the most prevalent refractive
errors that corrected to 6/6, while. Amblyopia was more
common in hypermetropic. Anisometropia was the least
common of the sample.
