Platelet-rich plasma (PRP) contains more concentrated platelets than autologous serum or whole blood. Platelets contain a concentrated amount of growth factors and are critically important in the wound-healing process, especially on the eye’s surface. Platelets transfer their healing properties rapidly to the damaged/wound site and adhere to the damaged tissue. This then initiates a healing reaction that includes the release of a variety of cytokines and growth factors. The α-granules within these platelets release many growth factors, such as platelet-derived growth factors, platelet factor IV, and transforming growth factor (TGF)-β. Thus, PRP is known to harbor high concentrations of growth factors and can promote effective, rapid wound healing.
PRP eye drops have been used to treat ocular surface disease, corneal ulcers, recurrent corneal erosions, eye pain after LASIK and PRK, and dry eye.

The objective of this study was to evaluate the use of autologous platelet-rich plasma (PRP) eye drops as monotherapy for the treatment of moderate to severe cases of dry eye disease.
Three hundred and sixty-eight patients with moderate to severe dry eye disease (DED) were included in this prospective case series. Subjects were classified as evaporative DED (EDED) or aqueous deficient DED (ADDED). Improvement of the DED subjective symptoms, corneal fluorescein staining (CFS), and corrected distance visual acuity (BCVA) were evaluated. We also analysed how many rounds of PRP therapy were used.
Two hundred and ninety-seven (80.7%) patients were women, and 71 (19.3%) were men. Two hundred and thirty-two (63%) patients had EDED, while 136 (37%) had ADDED. After 6 weeks of monotherapy treatment with autologous PRP, dry eye symptoms improved in 322 (87.5%) cases. A decrease of CFS was observed in 280 (76.1%) patients. One hundred and six (28.8%) patients improved at least 1 line of BCVA. The scores in the ocular Surface Disease Index and the Oxford scale of corneal fluorescein staining decreased statistically after the treatment (p < 0.05).
The topical use of autologous platelet-rich plasma as monotherapy is an effective treatment to improve signs and symptoms in patients suffering from moderate to severe chronic DED.
