Abstract Details

Purpose:

To identify predictive factors for keratoconus progression through a retrospective review of paediatric keratoconus patients.

Setting:

This review was performed at Manchester Royal Eye Hospital, United Kingdom.

Methods:

This was a retrospective review of 19 patients age <18 years diagnosed with keratoconus. Patients all had 2 or more ophthalmic examinations and tomographic measurements. Eyes that had previously had surgery were excluded. Rate of keratoconus progression was calculated by comparing the thinnest corneal measurement at 2 scans, and divided by time between scans (months). Data points had a 5 month interval where possible. Rate of progression was charted against Kmean, thinnest portion of the cornea, and posterior elevation.

Results:

37 eyes of 19 patients were reviewed. 6 eyes developed corneal scarring. Of the remaining 31 eyes, 26 progressed. We found that predictors of more rapid progression were a thin cornea <450 microns, Kmax >55diopters and a posterior elevation >80 microns.

Conclusions:

The majority of cases of paediatric keratoconus in this review progressed. Corneal thickness <450 microns, Kmean >55 dioptres and posterior elevation >80 microns are possible predictive factors indicating higher rate of progression in paediatric keratoconus.
