Relationship between cataract severity and socioeconomic status

Area of Science:

• Ophthalmology
• Public Health
• Sociology

Background:

• Cataract severity can impact visual acuity and quality of life.
• Socioeconomic status (SES) is a known determinant of health outcomes.
• The relationship between SES and cataract severity requires further investigation.

Purpose of the Study:

• To investigate the association between socioeconomic status and cataract severity.
• To determine if lower SES correlates with more severe cataracts requiring phacoemulsification.

Main Methods:

• Retrospective observational case series of 1350 eyes undergoing cataract extraction.
• Cataract severity measured by phacoemulsification time.
• SES assessed using census data: median income, education, common-law couples, and employment rate.
• Multivariate regression analyses controlled for patient age.

Main Results:

• Lower median income was significantly associated with increased cataract severity (p=0.001).
• Higher proportion of common-law couples (p=0.012) and unemployment rates (p=0.002) correlated with more severe cataracts.
• These associations remained significant after controlling for patient age.

Conclusions:

• Patients with lower socioeconomic status present with more severe cataracts.
• SES is a significant factor influencing cataract development and severity.
• Findings highlight potential disparities in eye health based on socioeconomic factors.
