Profils d'évolution des différents paramètres de la cornée dans le kératocône progressif

Abstract : Purpose: To analyze the evolution profiles of several corneal topographic and tomographic parameters in progressive keratoconus and compare to the kinetic of evolution of the anterior keratometry. Methods: One hundred and nine eyes of 55 patients were prospectively enrolled and followed every 3 months during at least 1 year. Fifty-six corneal parameters were measured at each visit using a combined Placido-based and dual Scheimpflug imaging system. Percentage of progression (PP) between each visit was calculated for each parameter. Results: At 1 year, 13% (15/109) of eyes progressed with an increase in anterior keratometry of 1D or more. Among these eyes, posterior steepest keratometry and vertical coma had a significantly higher PP (p < 0.01, student test) and an earlier progression than that with anterior keratometry. Conclusion: Posterior keratometry and vertical coma were modified earlier than the anterior keratometry in progressive keratoconus eyes. These parameters may be relevant warning signs when monitoring progressive keratoconus.
