What is Tomographic Indices as Possible Risk Factors for Progression in Pediatric Keratoconus about?

## Purpose: To determine whether corneal tomography can help predict the risk of progression of keratoconus in children. ## Methods: The medical records of pediatric patients with keratoconus presenting to a large tertiary institution in the uk from 2009 to 2014 were reviewed retrospectively. patients underwent serial clinical examination and corneal tomography. the minimum follow-up period was 5 months. patients with a history of eye surgery including corneal crosslinking were excluded. the following tomographic parameters were analyzed: thinnest corneal thickness (tct), average central corneal keratometry (km), and maximum central posterior elevation (mcpe). the rate of progressive corneal thinning, in μm/month, was calculated as the difference between tct on presentation and at the most recent visit divided by the time in months. ## Results: A total of 36 eyes of 19 patients (10-16 years of age) were included. mean follow-up was 19 months (range, 5-30 months). six eyes (17%) developed corneal scarring and 1 eye (3%) developed acute hydrops. of the 29 eyes that did not develop corneal scarring or hydrops, 24 (83%) demonstrated progressive corneal thinning over the period of the s
