Summary

Central corneal thickness (CCT) in older Latinos is thinner than in younger individuals. Thinner corneas are associated with lower intraocular pressure (IOP), potentially affecting IOP measurements.

Area of Science:

  • Ophthalmology
  • Corneal Research
  • Public Health

Background:

  • Central corneal thickness (CCT) is a key factor in glaucoma diagnosis and refractive surgery planning.
  • Understanding CCT variations across different ethnic groups is crucial for accurate clinical assessments.

Purpose of the Study:

  • To determine the central corneal thickness (CCT) in a Latino population aged 40 and older.
  • To investigate the relationship between CCT, age, and intraocular pressure (IOP) in this demographic.

Main Methods:

  • A population-based cohort of 1699 Latinos aged 40+ in La Puente, California, was studied.
  • Central corneal thickness (CCT) was measured using ultrasonic pachymetry.
  • Intraocular pressure (IOP) was measured via applanation tonometry.

Main Results:

  • The average CCT was 546.9 +/- 33.5 micrometers.
  • Older participants (>=70 years) had significantly thinner corneas than younger participants (40-49 years).
  • Eyes with ocular hypertension had thicker corneas; thinner corneas were associated with lower IOP.

Conclusions:

  • Latino CCT is ethnically variable, falling between previously reported values for Whites and those for African Americans and Asians.
  • Age-related thinning of the cornea was observed in older Latinos.
  • Significant interocular differences in CCT warrant evaluation for corneal disease; CCT influences IOP measurement accuracy.
