Morphological variants in keratoconus: anatomical observation or aetiologically significant?
Аннотация
PURPOSE: Two morphological cone variants are identified in keratoconus; nipple and oval. The present study was designed to assess the impact of aetiological factors on cone morphology.
METHODS
As part of a prospective controlled study, keratoconic subjects from a suburban practice (n = 89) underwent videokeratograph examination and completed a questionnaire detailing aetiological factors.
RESULTS
Comparison of 95% confidence limits (CL; bootstrap method) for apical power between the two cone morphology groups showed no statistical significance. Oval cones were located at a greater eccentricity than nipple cones, as their definitions suggest. Associations between aetiological factors examined and the morphology of the cone were not significant (bootstrapped 95% CL).
CONCLUSION
Despite the suggestion of morphological variants in keratoconus, the results of the present study suggest a common cone aetiology.
