Purpose To investigate the potential role of autologous platelet-rich plasma in promoting healing in dormant corneal ulcers.
Design Prospective, consecutive, interventional, noncomparative, nonrandomized, observational study.
Participants Forty eyes of 38 patients with dormant corneal ulcers.
Methods Autologous platelet-rich plasma was used in a total of 40 eyes with dormant corneal ulcers divided into 2 groups: group I, 26 eyes treated with topical eyedrops of autologous platelet-rich plasma (12 neurotrophic, 9 herpetic, and 5 immunological ulcers), and group II, 14 eyes treated surgically with a solid clot of autologous platelet-rich plasma combined with amniotic membrane transplantation in perforated corneas or with impending perforation. The treatment was used in patients with chronic nonhealing ulcers (mean, 2 years of evolution) that had been unresponsive to conventional topical therapy. Autologous blood from each patient was obtained by venipuncture, and platelet-rich plasma was prepared from each blood sample without additives.
