Ocular biometry in an adult Ghanaian population

Abstract

Purpose: To measure ocular biometry and its correlates in an adult population. Materials and Methods: The measured biometric data included central corneal thickness (CCT), corneal power (K), anterior chamber depth (ACD), lens thickness (LT), vitreous chamber depth (VCD), axial length (AL), and spherical refractive error (SER) in 162 adult eyes. Results: The mean CCT was 506.7 ± 39.2 μm, mean K was: K1 = 42.50 ± 2.00 D, K2 = 43.50 ± 2.44 D, the mean AL was 24.2 ± 1.3 mm, ACD had a mean of 3.5 ± 0.6 mm, LT (mean of 3.9 ± 0.8 mm), VCD (mean of 16.4 ± 1.39 mm), and SER ranged from -10.00 D – +8.00 D. There were no significant correlations between the CCT and SER (r = 0.06, P = 0.44), LT (r = 0.06, P = 0.59), ACD (r = −0.12, P = 0.12), AL (r = −0.02, P = 0.98), and VCD (r = −0.05, P = 0.68). Pearson's correlation coefficient tests showed that AL was significantly positively correlated with ACD (r = 0.4, P
