Hertel Exophthalmometry Values in Mexican Adults

Condition(s) studied

Investigational drug(s) / intervention(s)

Hertel Exophthalmometry: Standardized bilateral Hertel exophthalmometry performed using a Hertel exophthalmometer to measure globe protrusion.

Study summary

Proptosis assessment using Hertel exophthalmometry is an essential part of the ophthalmic examination, but normal reference values vary among different populations. This observational study aims to establish normative Hertel exophthalmometry values in Mexican adults and to evaluate their association with demographic characteristics (such as age and sex) and systemic diseases. Healthy adult participants and adults with selected systemic conditions will undergo standardized Hertel exophthalmometry measurements. The findings are expected to provide population-specific reference values that may improve the clinical assessment of orbital diseases in the Mexican population.

Eligibility

Primary outcome measure(s)

• Hertel Exophthalmometry Value — At baseline
  Bilateral Hertel exophthalmometry measurements (millimeters) obtained using a standardized Hertel exophthalmometer. Normative values will be estimated and summarized for the study population.
