    “…However, no study has yet described the presence of TC in the human eye and in particular, within the stromal compartment of the cornea. To address this issue, samples of normal and pathologic (keratoconic) human corneas were tested by immunohistochemistry for CD34, platelet‐derived growth factor receptor α (PDGFRα) and c‐kit/CD117 or examined by transmission electron microscopy. …”

    “…Due to the difficulty of estimating the daily exposure to light; research is needed to determine how much natural and man-made lights could affect the cornea. Visible light radiation could have damaging effect on the human eye; the type and degree of damage are related to the duration and the cumulative exposure as well as to the intensity of the rays. …”
