What is Pterygium and what causes it?
Pterygium is a disorder that occurs by an overgrowth of the proximal nail fold on to the nail bed. In severe cases the nail plate is eventually replaced with scar-like tissue. The condition typically effects the nail matrix, nail bed and nail plate but sometimes all parts of the nail unit are involved.
Common causes of the condition include systemic immune disorders, traumatisation, chemical burns and injuries.
Who does it affect?
Anyone but ventral pterygium is more common in women.
