ABSTRACT
A
cross-sectional study was undertaken to determine the refractive and biometric status
of premature children without Retinopathy of Prematurity (ROP) and full term children. Fifty eight children between the ages
of 3 and 7 years (32 children born premature without ROP and another 26 children born full term and normal) were
examined. Refractive error, corneal curvature, axial length, anterior chamber
depth and crystalline lens thickness were determined. The results revealed that
children between the age of 3 years and 7 years were emmetropic, irrespective
of whether they were born premature without ROP or full term. However, children born premature without ROP had significantly steeper corneas (t = 3.14, p = 0.0349),
shorter axial lengths (t = 3.18, p = 0.0313) and thicker crystalline lens (t =
3.31, p = 0.0256) compared to children born full term within the same age
group. This study suggests that compensation in ocular parameters can occur to
maintain emmetropia, mainly by adjustment of axial length and corneal
curvature.
Keywords:
Axial length; corneal curvature; crystalline lens thickness; premature without
retinopathy of prematurity; refractive error
ABSTRAK
Satu kajian
keratan rentas telah dijalankan untuk menentukan status refraksi dan biometri
kanak-kanak yang dilahirkan pramatang tanpa Retinopati of Pramatang (ROP) dan kanak-kanak yang dilahirkan cukup matang. Seramai 58
kanak-kanak dengan umur antara 3 dan 7 tahun (32 kanak-kanak dilahirkan
pramatang tanpa ROP dan 26
kanak-kanak dilahirkan cukup matang dan normal) telah diperiksa. Ralat
refraksi, kelengkungan kornea, panjang aksial, kedalaman kamar anterior dan
ketebalan kanta kristalin telah diukur. Keputusan kajian menunjukkan
kanak-kanak antara umur 3 tahun dan 7 tahun adalah emetrop, walaupun dilahirkan
pramatang tanpa ROP atau
dilahirkan cukup matang. Walau bagaimanapun, kanak-kanak yang dilahirkan
pramatang tanpa ROP mempunyai
kornea yang lebih curam (t = 3.14, p = 0.0349), panjang aksial yang lebih
pendek (t = 3.18, p = 0.0313) dan kanta kristalin yang lebih tebal (t = 3.31, p
= 0.0256) secara statistik berbanding kanak-kanak yang dilahirkan cukup matang
dalam kumpulan umur yang sama. Kajian ini mencadangkan kompensasi parameter
okular berlaku untuk mengekalkan emetropia, terutamanya dengan ubahsuaian
panjang aksial dan kelengkungan kornea.
Kata kunci:
Kelengkungan kornea; ketebalan kanta habluran; panjang aksial; pramatang tanpa
retionopati pramatang; ralat refraksi
