Primary open-angle glaucoma (POAG) disproportionately affects Black individuals, leading to earlier onset and faster progression. This review examines POAG in Black populations, highlighting disparities in risk factors, disease progression, and treatment.

Area of Science:

  • Ophthalmology
  • Public Health
  • Genetics

Background:

  • Primary open-angle glaucoma (POAG) is a leading cause of irreversible blindness globally.
  • POAG exhibits a significantly higher prevalence and more aggressive progression in Black individuals compared to White individuals.
  • Racial disparities in POAG necessitate a comprehensive understanding of contributing factors and outcomes in Black populations.

Purpose of the Study:

  • To provide a comprehensive review of current knowledge regarding primary open-angle glaucoma (POAG) specifically in Black populations.
  • To elucidate the unique epidemiological, clinical, and therapeutic aspects of POAG in individuals of Black ancestry.
  • To highlight the disparities in POAG prevalence, progression, and treatment response in Black individuals.

Main Methods:

Related Experiment Videos

  • Literature review synthesizing existing research on POAG in Black populations.
  • Analysis of studies reporting racial differences in optic disk parameters and intraocular pressure.
  • Examination of the impact of comorbidities like diabetes and hypertension on POAG in Black individuals.
  • Review of treatment responses and accessibility challenges for POAG in Black patients.

Main Results:

  • Black individuals experience a higher prevalence of POAG, with onset approximately 10 years earlier and more rapid progression.
  • Larger optic disk sizes are consistently reported in Black individuals, potentially influencing other optic disk parameters.
  • Conflicting data exists on racial differences in intraocular pressure, possibly influenced by corneal thickness.
  • Higher prevalence of diabetes and hypertension in Black populations may indirectly relate to POAG.
  • Black individuals demonstrate reduced responsiveness to both medical and surgical POAG treatments.
  • Reduced access to care and lower awareness of POAG risks are prevalent in Black communities.

Conclusions:

  • POAG presents unique challenges in Black populations, characterized by earlier onset, faster progression, and poorer treatment outcomes.
  • Addressing racial disparities in POAG requires a multifaceted approach, including improved screening, tailored treatments, and enhanced patient education.
  • Further research is needed to fully understand the genetic and environmental factors contributing to POAG disparities in Black individuals.
