Abstract Details

Purpose:

The purpose of this study is to characterize pediatric keratoconus patients by analyzing tomographic characteristics in the highest pediatric sample, to our knowledge, available in the scientific literature.

Setting:

Retrospective, cross-sectional, multicenter study

Methods:

278 eyes from 139 pediatric keratoconus (KC) patients were evaluated. Among the criteria of selection were; (1) 18 years old or less, (2) KC first diagnosis tomographic maps prior to 18 years old, (3) unilateral or bilateral KC. For KC diagnosis and classification, we selected the parameters Keratoconus Index (KI ≥ 1.07) and Topographic Keratoconus Classification (TKC ≥ 1). Patients were divided into two and three groups, based on age ranges. Statistical analysis was performed with SPSS statistics 25.0. The t student test was performed. ANOVA factor was performed in the three-group comparison.

Results:

230 eyes were diagnosed with pediatric KC. Mean age was 15.48 ± 2.33 (6 to 18) years old. Our results showed how there are differences in terms of TKC (2.08 ± 0.89 and 2.35, P< 0.05), KI (1.20 ± 0.12 and 1.25 ± 0.16, P< 0.05), primary (-1.88 ± 1.39 and -2.40 ± 1.26, P<0.05) and secondary comma (-0.24 ± 0.40 and -0.37 ± 0.41, P< 0.05) aberration between under 14 years and above 17 years, respectively.

Conclusions:

Our findings revealed that keratoconus is aggressive in the pediatric and juvenile population with high grade at first diagnosed; thus, we recommend they should be closely monitored and intensively treated.  Corneal tomography should be systematically performed in children with corneal astigmatism of recent onset.
