Etymology

The Hudson–Stahli line is named after the American ophthalmologists, Benjamin Hudson and Robert Stahli, who first described it in 1963.

Description

The Hudson–Stahli line is a horizontal line that appears in the lower third of the cornea. It is composed of iron deposits and is most commonly seen in individuals over the age of 40. The line is usually 1-2mm in height and can extend across the entire width of the cornea. It is more commonly observed in the lower half of the cornea, but can occasionally be seen in the upper half as well.

Clinical significance

The presence of a Hudson–Stahli line is generally considered to be a normal age-related change and is not associated with any disease or disorder. However, it can sometimes be mistaken for other conditions that also result in iron deposition in the cornea, such as Fleischer ring or Ferry's line. Therefore, it is important for healthcare professionals to be aware of this condition and to differentiate it from other similar conditions.
