The aim of this study was to record anterior segment indices in Corum and surrounding regions and to compare these data according to age and gender. A total of 566 (265 male, 301 female) patient data sets were reviewed. Age groups were formed as group lower age (GLA) (aged 18-39 years, 140 male, 143 female) and group higher age (GHA) (aged 40-65 years, 125 male, 158 female). Evaluated indices were corneal central thickness (CCT), anterior chamber depth (ACD), anterior chamber angle (ACA), flat keratometry (K1), steep keratometry (K2) and average keratometry (Kavg). The ACD (3.71 + 0.36 mm for GLA and 3.23 + 0.44 mm for GHA), ACA (43.22 + 6.39 for GLA and 37.76 + 8.700 for GHA) and K2 (44.49 + 1.69D for GLA and 43.99 + 1.53D for GHA) results were all significantly lower in GHA compared with GLA (p<0.0001, p<0.0001 and p=0.001, respectively). Men had higher ACD values (p=0.002) than women. Women's ACAs were narrower (p<0.0001) than men. Women showed higher keratometry results as opposed to men (p<0.0001 for all). However, when gender comparison was done among GLA, there was no difference of ACD and ACA between genders. We showed our regional anterior segment results were different from other regions in the country. In addition, we showed that the significant differences of ACD and ACA did not present below the age of 40, as opposed with previous literature. It was suggested that gender combined with age gave significant differences of ACD and ACA, but not gender alone.

Tujuan kajian ini adalah untuk mencatat indeks segmen anterior di Corum dan bahagian sekeliling serta membandingkan data tersebut berdasarkan umur dan jantina. Sejumlah 566 (265 lelaki, 301 perempuan) data pesakit telah dikaji. Kumpulan umur dibahagi kepada kumpulan umur rendah (GLA) (berumur antara 18-39 tahun, 140 lelaki, 143 perempuan) dan kumpulan umur tinggi (GHA) (berumur antara 40-65 tahun, 125 lelaki, 158 perempuan). Indeks yang dikaji termasuklah ketebalan korneal pusat (CCT), kedalaman anterior kamar (ACD), sudut anterior kamar (ACA), keratometri rata (K1), keratometri condong (K2) dan keratometri purata (Kavg). Hasil ACD (3.71 + 0.36 mm untuk GLA dan 3.23 + 0.44 mm untuk GHA), ACA (43.22 + 6.39 untuk GLA dan 37.76 + 8.70 untuk GHA) dan K2 (44.49 + 1.69D untuk GLA dan 43.99 + 1.53D untuk GHA) adalah rendah di kalangan GHA, berbanding dengan GLA dengan signifikasi (p<0.0001, p<0.0001 dan p=0.001). Lelaki mempunyai nilai ACD yang lebih tinggi (p=0.002) berbanding dengan perempuan. Sudut anterior kamar di kalangan perempuan lebih sempit daripada lelaki (p<0.0001). Perempuan mempunyai nilai keratometri yang lebih tinggi berbanding dengan lelaki (p<0.0001 untuk semua). Walau bagaimanapun, perbandingan antara jantina dilakukan di kalangan GLA menunjukkan tiada perbezaan antara ACD dan ACA. Kajian ini menunjukkan indeks segmen anterior adalah berbeza dengan data di kawasan lain dalam negara. Di samping itu, kajian ini menunjukkan gabungan faktor jantina dan umur memberi perbezaan ACD dan ACA, tetapi tidak ketara antara jantina sahaja.
