To determine the range and mean of axial length (AL), anterior chamber depth (ACD), lens thickness (LT), and vitreous chamber depth (VCD) in emmetropic Sudanese. Material and Methods: This is a cross sectional study was done in a period from September 2018 to February 2019 at Khartoum eye hospital. The sample was selected from patients presenting to the optometry department and volunteers who accept to be enrolled in the study. The range of ages was between 18-50 years old. It includes 105 males and 150 females. Participants with ocular surgery, extensive pterygium, recent trauma were excluded. All participants were examined for vision and refraction tests for both eyes then A-scan test for right eye just. Results: Mean of axial length was 22.61± 0.83mm (19.14-24.92), mean of anterior chamber depth was 2.95±0.45mm (1.96-5.78), mean of lens thickness was 3.65±0.41mm (2.83-4.94), and mean of vitreous chamber depth was16.01±0.82mm (13.60-18.08). Axial length is significantly higher in men than in women (P value 0.029) as same as vitreous chamber depth (P value 0.040). Person coefficient correlation test demonstrated that negative relation had been found between age and anterior chamber depth -0.146 (P value 0.020) and positive relation had been found between age and vitreous chamber depth 0.138 (P value 0.027). Conclution: The study showed that the axial length mean is higher in males compared to females. Anterior chamber depth decreased with age and lens thickness increased with age.
