To screen a population of Jewish children and teenagers living in Rome (Italy) for corneal abnormalities in particular for keratoconus.
542 eyes of 271 students, ages 10 to 20 have been examined at the Hebrew School of Rome, using Sirius corneal topographer (CSO), a combination between a rotating Scheimpflug camera and a Placido disk. Minimum corneal thickness, central corneal thickness, 5 mm cylinder front and total, anterior and posterior corneal asymmetry and other useful corneal indices have been evaluated.
A total of 127 boys and 144 girls participated in the study. Corneal topography suggestive strongly for corneal abnormality was present in both eyes of 1 student (0,36%). Corneas examined showed a prolate profile. Anterior Mean simK avg was 7,751 (SD 0,81); minimum corneal thickness was 547,99 (SD30,55), central corneal thickness was 551,46 (SD 30,56) mean 5 mm cylinder front was -0,79 (SD 0,44) and total was 0,55 (SD 0,36), anterior corneal asymmetry was -0,058 (SD 0,53) and posterior corneal asymmetry was 0,0041 (SD 0,93).
corneas examined had a normal prolate profile. Although the studied population belongs to a closed community and previous studies report one of the most elevated world prevalences of keratoconus in Jewish population (2%) , the prevalence of corneal abnormalities in our study was not the same. Many explanations should be given. The prevalence of abnormal corneas was 0,36%, probably had an early keratoconus.
