Prevalence of the Hudson-Stähli line of the cornea

The prevalence of the corneal Hudson-Stähli line among 400 eyes was found to range from 5.3% of the eyes of patients aged 11-20 years to 100% of eyes of patients aged 81-90 years. In 87.3% of patients over 50 years of age corneas were affected; this percentage is considerably higher than previous estimates. Up to the age of 60 years it occurs more frequently in men than in women.
