To analyze the association between angle α and ocular biometry in the general population at a third-level ophthalmology hospital.
Anterior Segment Surgery Department, Asociación para Evitar la Ceguera en México I.A.P., Mexico City, Mexico.
Prospective, cross-sectional study.
Healthy subjects who attended the hospital for a comprehensive ophthalmological evaluation were examined, and general data were collected. A complete ophthalmological assessment and biomicroscopy evaluation were performed and biometry and clinical data were obtained, including visual acuity, axial length (AL), keratometry (K), white-to-white (WTW) measurement. An OPD-Scan III analyzer was used to assess both the angle α distance and biometry parameters.
74 eyes from the same number of patients were included; 43 (58.10%) were women. A statistically significant inverse correlation was found between the angle α and the AL (r = -0.585; P < .0001) and between the WTW distance and the mean K (r = 0.557; P < .0001). A significant correlation was found between the mean K and the angle α (r = 0.271; P = .019). A significant inverse correlation was observed regarding the WTW distance and angle α (r = -0.359; P = .001). By contrast, a direct correlation was evidenced between the WTW and the AL (r = 0.385; P = .0007).
There was a significant inverse correlation between the AL and the angle α magnitude. Hyperopic patients demonstrated significantly higher angle α values when compared with those of myopic patients. In addition, hyperopic eyes with steeper mean K and lesser WTW distance were associated with an increased angle α.
分析三级眼科医院普通人群中 α 角与眼球生物测量的关系。
墨西哥城墨西哥预防失明协会眼科前段手术科。
前瞻性、横断面研究。
对前来医院进行全面眼科评估的健康受试者进行检查，并收集一般数据。进行全面眼科评估和生物显微镜评估，并获得生物测量和临床数据，包括视力、眼轴（AL）、角膜曲率（K）、白到白（WTW）测量值。使用 OPD-Scan III 分析仪评估 α 角距离和生物测量参数。
纳入 74 只眼，均来自相同数量的患者；43 只眼（58.10%）为女性。α 角与 AL 之间存在显著的负相关关系（r = -0.585；P <.0001），WTW 距离与平均 K 之间存在显著的正相关关系（r = 0.557；P <.0001）。平均 K 与α 角之间存在显著的正相关关系（r = 0.271；P =.019）。WTW 距离与α 角之间存在显著的负相关关系（r = -0.359；P =.001）。相反，WTW 与 AL 之间存在直接相关关系（r = 0.385；P =.0007）。
AL 与 α 角大小之间存在显著的负相关关系。远视患者的α 角值明显高于近视患者。此外，具有更大平均 K 和更小 WTW 距离的远视眼与更大的α 角相关。
