Hertel Exophthalmometry Values in Mexican Adults

Hertel Exophthalmometry Values in Mexican Adults and Their Association With Demographic Factors and Systemic Diseases

Sponsor

Instituto de Oftalmología Fundación Conde de Valenciana

Enrollment

300 participants

Start Date

Apr 21, 2026

Study Type

OBSERVATIONAL

Conditions

ExophthalmometryNormal Exophthalmometric Values

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

Min Age: 18 Years

Inclusion Criteria5

  • 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.
  • Participants with or without previously diagnosed systemic diseases.

Exclusion Criteria7

  • 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.
  • Craniofacial abnormalities or facial asymmetry that may interfere with Hertel exophthalmometry.
  • Ocular or eyelid conditions that prevent accurate positioning or measurement with the Hertel exophthalmometer.
  • Inability to cooperate with the examination or obtain a reliable exophthalmometry measurement.
