GlossaryCorneal Epithelium

outermost cell layer of the eye's clear front surface

The corneal epithelium is the outermost layer of the cornea, which is the clear, dome-shaped surface that covers the front of the eye. This thin, protective layer of cells helps to shield the eye from dust, debris, and bacteria, while also playing a crucial role in maintaining clear vision by providing a smooth surface for light to enter the eye.

community If You Have DUPA, PLEASE READ THIS: Everyone Should Be Scalp Biopsied

in Research 830 upvotes 1 year ago

Scalp biopsies are crucial for diagnosing hair loss conditions like Diffuse Unpatterned Alopecia (DUPA) and retrograde hair loss, as treatments like finasteride and dutasteride may not be effective if other conditions are present. Combining PPAR-GAMMA agonists with retinoids could improve treatments for conditions like Lichen Planopilaris.
