Racial Disparities in Corneal Transplantation Rates, Complications, and Outcomes

Area of Science:

• Ophthalmology
• Transplantation immunology
• Public health

Background:

• Corneal transplantation is a common procedure to restore vision or alleviate pain.
• The cornea possesses immune privilege, leading to high initial graft success rates (around 90%).
• Graft survival rates can vary due to patient-specific factors, diagnosis, and donor characteristics.

Purpose of the Study:

• To investigate potential differences in corneal transplantation outcomes based on patient race and ethnicity.
• To review existing ophthalmic literature for associations between race/ethnicity and corneal graft success.
• To identify if race is a significant factor influencing graft rejection or failure.

Main Methods:

• Systematic review of ophthalmic literature.
• Analysis of studies examining corneal transplantation rates and outcomes.
• Focus on research that stratifies data by race and ethnicity.

Main Results:

• A limited number of studies indicate a potential link between race and increased risk of graft rejection.
• Preliminary findings suggest race may be a factor in corneal graft failure.
• Evidence regarding ethnic and racial variations in corneal transplant outcomes is currently sparse.

Conclusions:

• Race and ethnicity may represent significant risk factors in corneal transplantation.
• Further comprehensive research is required to validate the association between race and corneal graft outcomes.
• Understanding these disparities is crucial for improving patient care and transplant success rates across diverse populations.
