Primary angle-closure glaucoma is more common in East Asian populations. Further research is needed to understand ethnic variations in glaucoma development and mechanisms.

Area of Science:

  • Ophthalmology
  • Public Health
  • Genetics

Background:

  • Primary angle-closure glaucoma (PACG) disproportionately affects East Asian populations.
  • PACG is a significant public health concern due to its high rate of visual morbidity.
  • Inconsistent diagnostic criteria hinder accurate data interpretation across studies.

Purpose of the Study:

  • To review existing studies on primary angle-closure glaucoma (PACG) prevalence.
  • To analyze ethnic variations in PACG incidence and prevalence.
  • To establish a consistent classification system for PACG detection and diagnosis.

Main Methods:

  • Review of observational studies from diverse countries.
  • Analysis of reported incidence and prevalence data for PACG.

  • Examination of studies investigating PACG mechanisms and natural history in Asian populations.

    • Main Results:

    • Consistent evidence confirms ethnic variations in PACG occurrence.
    • Asian populations exhibit a higher frequency of PACG compared to European or African descent.
    • Anterior chamber depth and peripheral anterior synechiae are implicated in PACG mechanisms.

    Conclusions:

    • Ethnic variations in primary angle-closure glaucoma (PACG) are well-established.
    • Differences in anterior chamber depth may contribute to PACG development in certain ethnic groups.
    • Longitudinal studies are required to explore changes in anterior chamber depth and synechiae, and to elucidate PACG mechanisms.
