ABSTRAK
Kajian ini bertujuan untuk mengetahui status visual pelajar
berpenglihatan terhad dan mengenal pasti pelajar bermasalah penglihatan yang
boleh mendapat manfaat melalui penggunaan alat bantuan penglihatan terhad. Seramai 113 pelajar berpenglihatan terhad
dari sekolah pendidikan khas mengambil bahagian. Akuiti
visual jauh dan dekat diukur dengan dan tanpa alat bantuan penglihatan terhad. Pelajar yang memerlukan pemeriksaan lanjutan dirujuk ke Klinik Penglihatan
Terhad, Universiti Kebangsaan Malaysia (KPT UKM). 31% pelajar berkategori berpenglihatan
terhad dengan penglihatan jauh di antara 6/18 sehingga 6/95, manakala 67%
pelajar berkategori buta. 2% pelajar pula mempunyai
akuiti yang lebih baik dari 6/18. Akuiti visual dekat
bagi pelajar-pelajar ini adalah di antara N4 hingga N64. Alat bantuan
penglihatan terhad seperti kanta pembesar berpemegang, kanta pembesar berdiri
dan teleskop dimiliki oleh hanya 17% pelajar dari kategori pelajar
berpenglihatan terhad. Kajian ini juga menunjukkan bahawa 85%
daripada pelajar yang dirujuk ke KPT UKM mendapat menafaat dari penggunaan alat bantuan
penglihatan terhad. Capaian kepada perkhidmatan
pemeriksaan dan jagaan mata bagi pelajar berpenglihatan terhad perlu diwujudkan
agar pelajar-pelajar ini dapat dikesan awal dan alat bantuan penglihatan terhad
yang sesuai dapat diberikan. Kajian ini menekankan kepentingan peranan
ibu bapa, guru-guru dan optometris dalam memastikan masalah/gangguan
penglihatan kanak-kanak ini ditangani dengan berkesan.
Kata kunci:
Alat bantuan penglihatan terhad; pemeriksaan penglihatan terhad
ABSTRACT
The purpose
of this study is to determine the visual status and effectiveness of low vision
devices among visually impaired school children. One hundred and thirteen
students from the special education schools took part in this study. Distance
and near visual acuity were measured both with and without low vision devices.
Students needing further assessment were referred to the Low Vision Clinic (LVC) Universiti Kebangsaan Malaysia. On presentation, 31% of the
students were catagorised as low vision with distance acuity between 6/18 and
6/95 whereas 67% were blind. 2% were found to have distance acuity better than
6/18. The range of near visual acuity of these students was between N4 and N64.
Low vision devices such as hand held magnifier, stand magnifier and telescope, were owned by only 17% of low vision students. This study
showed that 85% of the students that were referred to the LVC benefited from low vision devices. Access to visual examinations
and eye care for students with needs to be provided so that these students can
be identified early and suitable low vision devices prescribed. This study
emphasises the importance of the role played by parents, teachers and
optometrists in the management of vision impairment in school children so that
their visual impairment can be rehabilitated effectively.
