Summary and Conclusion
All studied school students (1988 students), fulfilled the
questionnaire as regard socio-demographic data (age, sex, educational
stage, residence) ocular examination (lid, cornea, sclera and presence or
absence of squint, refraction of both eyes) presence of any general or
local disease, school response to the students’ complain and the response
of health insurance to the referral.
One hundred and ninety one student were chosen by systemic
random sample from all of the studied group and referred to outpatient
clinic of ophthalmology in Minoufya University Hospital to confirm the
data .
As regard the demographic data of the studied group , the total
number of the students examined was 1988 where the total number
of the reexamined group was 191 .
Among the studied group (1988), local examination revealed that only
one student (0.1% ) had squint and there is no comment by the nurse on
local examination items as led , cornea and sclera. Among the
reexamined group whose are examined by ophthalmogist , there are two
students had led problems with prevalence rate 1% and one student has
corneal problems with prevalence rate 0.5% and there was no cases with
squint or scleral abnormalities .
On comparing screening results(1988 students) and re-examination
results of systemic random sample chosen group (191students) there was
non- significance difference between both groups regarding local
examination (P>0.05).
Among the studied group the prevalence of abnormal eye refraction
68
Summary and Conclusion
(≤6/18) was 2.5% and 2.9% in left and right eyes consequently , while in
both eyes it was 3.2% . And in the reexamined group the prevalence of
abnormal eye refraction(≤6/18) was 1% and 1.6% in left and right eyes
consequently , while in both eyes it was 1.6% .
Comparison between screening results(1988 students) and reexamination
results of systemic random sample chosen group
(191 students) revealed non significance difference between both groups
regarding eye refraction (P>0.05).
As regard distribution of type of eye refraction among the reexamined
group, myopia is the prevalent type of ametropia (14.6%) and
anisometropia shows the rarest type (1.6%) while prevalence of
hypermetropia is (3.6%) and prevalence of astigmatism is ( 7.9% ) .The
prevalence of normal eye vision is (72.3%). There was no comment by
the nurse on type of refraction.
There was non compliance of the students and their families to the
referral to the Health Insurance , as among the studied group (1988
student ) 83 student (4.2 % )were referred and only 5 students ( 6%)
respond to referral . Between re-examined group(1988 student) six
students (3.1 % ) were referred and only one student ( 0.5 %) responded
to referral .
On comparison between screening results and re-examination results
of systemic random sample chosen group there was non significant
difference between both groups regarding Health Insurance response
(P>0.05) .
