Hertel Exophthalmometry Values in Mexican Adults (HERTEL-MX)
Hertel Exophthalmometry Values in Mexican Adults and Their Association With Demographic Factors and Systemic Diseases
調査の概要
詳細な説明
Background: Hertel exophthalmometry is the most commonly used method for measuring globe protrusion in clinical practice. Normal exophthalmometric values vary according to ethnicity, sex, age, and craniofacial anatomy; therefore, population-specific reference values are necessary for accurate clinical interpretation. Currently, normative data for Mexican adults are limited.
Objective: To establish normative Hertel exophthalmometry values in Mexican adults and to evaluate their association with demographic characteristics and systemic diseases.
Methods: This is a prospective observational study. Adult participants attending the Ophthalmology Department will be consecutively recruited after providing written informed consent. Hertel exophthalmometry measurements will be obtained using a standardized technique by trained examiners. Demographic information, including age and sex, as well as relevant medical history and systemic diseases, will be recorded. The primary outcome is the distribution of Hertel exophthalmometry values in the study population. Secondary analyses will assess associations between exophthalmometric measurements and demographic or systemic variables.
Expected Significance: The study will provide normative Hertel exophthalmometry values for the Mexican adult population and identify factors associated with physiological variations in globe protrusion. These findings may improve the clinical evaluation of patients with suspected orbital disease and facilitate interpretation of Hertel exophthalmometry measurements in routine ophthalmic practice.
