Purpose of review
Blood-derived products [autologous serum
, eye platelet-rich plasma
(E-PRP), plasma rich in growth factors] are successful therapies for ocular surface
disorders, which compromise the integrity of the cornea surface and conjunctiva.
The most noteworthy and recent research has been directed towards hemoderivatives that include platelets. PRP for ophthalmologic use (E-PRP) has achieved successful outcomes as reported in the peer-review literature in the treatment of dry eye, post-laser in-situ keratomileusis ocular surface
syndrome, dormant ulcers, and for ocular surface
surgical reconstruction after corneal perforation associated to amniotic membrane transplantation, bovine pericardium membrane transplantation, or autologous fibrin membrane
combined with solid PRP clot.
PRP is a portion of the patient's own blood having a platelet concentration above baseline. The main advantage of PRP over other products is the presence of the platelets and associated with this the prolonged release of growth factors that are involved in the wound healing process of the cornea and conjunctival surface. E-PRP seems to be a reliable and effective therapeutic approach to enhance epithelial wound healing and promote ocular surface
regeneration in different pathological conditions.
