RESEARCH ON MEASUREMENTS OF OCULAR AXIAL LENGTH, ANTERIOR CHAMBER DEPTH, CENTRAL CORNEAL THICKNESS AND LENS THICKNESS IN VIETNAMESE PEOPLE FROM THE AGE OF 46 TO 65
Main Article Content
Abstract
Objectives: To determine the measurements of eyeball axial length, the depth of anterior chamber and central corneal thickness in Vietnamese people from the age of 46 to 65. Assess several relevant factors in mentioned ophthalmic anthropometry. Subjects and method: Cross-sectional descriptive study in 195 Vietnamese people from the age of 46 to 65 by IOLMaster700 at National Institute of Ophthalmology. Results: 195 people including 94 males (48.2%) and 101 females (51.7%), eyeball axial length: 23.13 ± 0.66 mm, anterior chamber depth: 3.15 ± 0.36 mm, central corneal thickness: 529.15 ± 30.57 µm, Lens thickness:4,38 ± 0,42 mm. These three measurements decrease with age and were higher in males (p<0.05). The eyeball axial length had positive correlation with anterior chamber depth and central corneal thickness. Lens thickness increases with age, there is no difference between men and women. Conclusion: Eyeball axial length, anterior chamber depth, central corneal thickness and lens thickness are valued in diagnosis and treatment in eye illnesses. This study determined these measurements in Vietnamese people, which contribute towards anthropometric indices of normal ophthalmology in genders and ages, playing a standard as comparing to cases of illnesses
