About this trial
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 criteria
This trial accepts healthy volunteersQualifiers
Adults aged 18 years or older.
Mexican participants or individuals who self-identify as Mexican.
Ability to understand the study procedures and provide written informed consent.
Ability to undergo bilateral Hertel exophthalmometry.
Disqualifiers
Active thyroid eye disease
History of orbital trauma or orbital fracture.
Previous orbital surgery, orbital decompression, or surgery that may alter globe position.
Presence or history of an orbital tumor, orbital inflammation, or orbital infection.
Trial population
Adult Mexican participants (≥18 years) recruited from the Ophthalmology Department who meet the eligibility criteria. Participants with and without systemic diseases will be included to establish normative Hertel exophthalmometry values and evaluate their association with demographic characteristics and systemic conditions.

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