Abstract

Background There are three main ocular indexes - ocular axial length, anterior chamber depth, and central corneal thickness. The measures of those three anthropometric parameters can help in ocular disease diagnostics. So, the main aim of the research was to determine the measurements of ocular axial length, the anterior chamber depth and central corneal thickness in Vietnamese people with the age of 46 to 65. Assess several relevant factors in mentioned ophthalmic anthropometry.


 Methods: A prospective cross – section study was conducted in Vietnameses people aged from 46 to 65 in Vietnam National Institute of Ophthalmology. Were measured data about axial length, anterior chamber depth, and central corneal thickness. Independent Sample T-Test and ANOVA test were used for comparison in groups. Were fixed the correlations between anthropometric ocular indices, age, and gender in help of Pearson Correlation, p < 0.05.


 Results: Have been recruited 390 eyes from 195 people in the experiment. The average ocular axial length was 23.13±0.66 mm, anterior chamber depth was in 3.15±0.36 mm, and central corneal thickness was fixed at 529.15±30.57 µm. All three biometric indices decreased with age and were higher in males (p<0.05). The axial length had positive correlation with anterior chamber depth (r=0.411, p<0.001) and central corneal thickness (r=0.141, p<0.001) . There was no correlation between anterior chamber depth and central corneal thickness (r=0.039; p=0.44).


 Conclusion: Was fixed, three anthropometric ocular indices relative to age and gender. Moreover, the axial length is correlated with anterior chamber depth and central corneal thickness.
