Purpose

Determine the pediatric prevalence of keratoconus (KC) using Placido corneal topography.

Setting

1.Children's Hospital "P&A Kyriakou", Athens, Greece

2.The Laservision Clinical and Research Institute, Athens, Greece

Methods

A prospective observational study was done on 425 subjects aged 3 to 18 years with Atlas Placido-based topography (Oculcus, Germany) and Tilleron automated reflection corneal imaging. The topography data were evaluated by 3 experienced clinicians and categorized as A: normal, B: suspicious and C: KC

The Tilleron data were processed by AI without any examiner intervention. The outcomes then compared to the topography assesssment data.

Results

Both topography and AI yielded a 10% suspicion for KC. Ages 3-12 was 5%, ages 12-18 was 12%, both devices were in agreeement in 98% of eyes evaluated.

Conclusions

The prevalence of KC in children in Greece is higher-especially in puberty-than previously reported, emphasizing the importance of sensitive screening for KC at its earliest manifestation as standard in pediatric comprehensive eye examinations.
