“…The mean ACD in this study was found to be 2.91 ± 0.43 mm; this is similar to a study from the USA (2.96 mm, among 29-90 year olds), 11 Singapore (2.90 mm among 40-81 year olds) 12 and Myanmar (2.82 mm among 40 years and above age). 13 This finding is, however, smaller than the one reported among blacks in South Africa (3.21 mm) 5 and Nigeria (3.3 mm for males and 3.24 mm for women) 6 but is larger than those reported from the People's Republic of China (2.67mm, among 50-93 year olds) 14 and Iran (2.62 mm, among 40-64 year olds). 15 The shallower ACD in our study may explain the higher prevalence of ACG shown in our clinic-based studies as compared with other African reports.…”

“…5 Another study from Nigeria showed body height to be independently associated with ocular AL and ACD while the body weight and BMI were not independently associated with any of the ocular biometric indices studied. 6 A possible association between central or limbal ACD and adult anthropometry has been described in several population-based studies. It was reported that there is a tendency for taller persons to have longer AL, deeper ACD, longer vitreous cavity distance, flatter corneas and thinner lenses, compared with shorter persons of similar weight, age, gender, and socioeconomic status.…”

Purpose: To determine the average values of ocular biometry dimensions and investigate their inter-correlations and their association with anthropometric measurements among Ethiopian adults with healthy eyes. Methods: A cross-sectional study was undertaken from June 2018 to July 2019. A total of 400 eyes of 200 subjects were included in the study. Univariable and multivariable linear regression were used to determine the association of demographic variables (age and sex) and anthropometric parameters (height, weight and BMI) with ocular biometric indices. Results: The mean age was 40.31±11.39 with a range from 18 to 69 years. The mean (SD) of horizontal corneal diameter, average corneal refractive power, anterior chamber depth (ACD), lens thickness (LT) and axial length (AL) were 11.45 (0.89) mm, 43.94 (9.78) diopter, 2.91 (0.43) mm, 4.29 (0.55) mm and 22.96 (0.82) mm, respectively. Age had a negative correlation with ACD (r= −0.196, p= <0.001) and positive correlation with lens thickness (r= 0.324, p<0.001). Height had a positive correlation with ACD (r=0.114, p=0.023) and LT (r= 0.206, p=<0.001) while negative correlation with LT (r=−0.129, p=0.01). In the multivariate linear regression, age (−0.009 (−0.013, −0.05), p-value <0.001) and sex (0.104 (0.01, 0.198), p-value=0.03) had a significant association with ACD and only gender (0.478 (0.302, 0.654), p-value <0.001) had a statistically significant association with lens thickness. Conclusion: This study determined the normative values for ocular biometric parameters among Ethiopian adults for the first time. Age, gender and height were associated with biometric indices. AL was significantly positively correlated with ACD and negatively correlated with LT. There was a negative correlation between LT and both AL and ACD.

“…En el presente estudio, la ACD fue mayor que la encontrada en China, Alemania, el Reino Unido, los Emiratos Árabes Unidos, Australia, México y los Estados Unidos 6,12,13,15,16,[22][23][24] , y similar a la reportada en estudios realizados en población latina en los Estados Unidos, Portugal y Nigeria 2,14,25 . En concordancia con la AL, la ACD fue mayor en los hombres que en las mujeres, variación atribuida a las diferencias en cuanto a peso y talla entre sexos.…”

“…La queratometría es otro parámetro clave en el cálculo correcto de una LIO. En este estudio se encontró una K promedio de 43.81 D, dimensión que se asemeja a la reportada en Portugal, México y Nigeria 14,16,25 . Además, mostró una tendencia al incremento con la edad y fue mayor en el sexo femenino, datos que se explican por la menor AL en los dos grupos descritos.…”

Introducción: Las estructuras ópticas pueden variar en su configuración y medida dependiendo de la edad, el sexo y la raza, por lo que su medición previa a la cirugía es un pilar fundamental para el cálculo correcto del lente intraocular. Caracterizar los rangos normales de estos parámetros en nuestra población suministra información importante que puede mejorar los resultados visuales tras la cirugía de catarata y alertar en aquellos casos que distan de la media de los rangos conocidos. Objetivo: Describir los parámetros biométricos oculares en pacientes candidatos a cirugía de catarata y analizar sus variaciones según la edad y el sexo. Método: Estudio observacional descriptivo, de corte transversal. Análisis retrospectivo de biometrías oculares realizadas con reflectometría óptica de baja coherencia en pacientes candidatos a cirugía de catarata. Resultados: Se evaluaron 820 ojos de 820 pacientes candidatos a cirugía de catarata, con una edad media de 68.1

“…Axial length (AL) of the eye is defined as the distance between the anterior corneal surface and internal limiting membrane of the retina. (1) In cataract surgery, accurate measurement of axial length (AL) and corneal power or corneal radius of curvature (K), are crucial to achieve satisfactory postoperative refractive results and reduce spectacle dependence.…”

Background: Precise measurement of the radius of curvature [K (mm)] and axial length (AL) of the eye are vital for a good outcome of a cataract extraction surgery. Average values of these dimensions of the optical components depend on race, age and gender. Although there are a number of studies that describe these mean parameters in the Caucasian, Hispanic and Asian populations, there has been little attention given to the African population. Objectives: The aim of this study was to estimate the biometric parameters of patients who had cataract surgery at University of Gondar (UoG), Tertiary eye care and training centre. Materials and methods: Hospital based cross sectional study was done on patients who visited UoG Tertiary Eye Care and Training Center for cataract extraction surgery. Righton retinomax K plus 3 autorefractor,(Hutama Medical, Indonesia) and Pac Scan 300A contact A scan ultrasound, (Sonomed Escalon, NY, USA) were used to measure K (mm) and AL and calculate intraocular lens (IOL) power, respectively. Data were collected using a structured questionnaire, then entered to SPSS version 25 statistical software and analyzed. Result: A total of 838 eyes (433 right eyes and 405 left eyes) of 486 of patients were included in this study. The mean age was 62.5 (SD12.88) years. The mean K1 and K2 were 7.75 (SD0.38) mm and 7.48 (SD 0.33) mm, respectively. The mean average of K1 and K2 (AVK) was 7.61 (SD0.33) mm. The mean AL measured was 23.06 (SD 1.05) mm and the mean Intraocular Lens (IOL) power calculated was 21.12 (SD 2.95) D. Significant difference in mean AVK and mean AL of the eye exists between male and female patients, p value =0.000. Conclusion: This study provides the mean values of radius of curvature of cornea, axial length of the eye and IOL power of patients who were about to undergo cataract extraction surgery at the study center. Male patients had steeper corneas and longer axial lengths than females. But age had a variable effect on both AVK and AL.
