Summary
The thinnest part of the cornea is thinner than the central and surrounding areas in healthy emmetropic individuals. This study provides key corneal thickness data for emmetropic subjects.
Area of Science:
- Ophthalmology
- Corneal Science
Background:
- Limited data exists on corneal thickness in healthy emmetropic subjects.
- Understanding corneal thickness is crucial for ophthalmic assessments.
Purpose of the Study:
- To analyze and report corneal thickness values in healthy emmetropic individuals.
- To compare thickness at the thinnest corneal site versus central and paracentral areas.
Main Methods:
- The study involved 124 healthy emmetropic white subjects.
- Corneal thickness was measured at the central, paracentral, and thinnest corneal sites.
- Differences in thickness were statistically analyzed using one-way ANOVA.
Main Results:
- The thinnest corneal site was significantly thinner than central and paracentral areas (p<0.001).
- Mean differences ranged from 12±6 µm at the center to 140±19 µm superonasally.
- Specific thickness variations were noted across all measured paracentral locations.
Conclusions:
- The thinnest corneal site is statistically thinner than the central and paracentral cornea in healthy emmetropic white subjects.
- These findings contribute valuable normative data for corneal thickness in this population.
