摘要: PURPOSE To determine the UV absorbance of corneal layers (epithelium, Bowman layer, stroma) in 240- to 400-nm range. METHODS Consecutive slices (100 microm) human cadaveric corneas were cut, and each sample was determined a scanning spectrophotometer. In some cases epithelium scraped off its measured separately. RESULTS The investigation UV-B absorption consecutive revealed evidence that is 1.8 times higher anterior 100 microm cornea than posterior layers. uniform, showing no further structural dependence. layer are both effective absorbers radiation. CONCLUSIONS These results suggest particularly important preventing damage by
