The aim of this study was to evaluate the clinical efficacy of a platelet-rich fibrin (PRF) membrane, which is
considered to be a new alternative surgical method in the treatment of vision-threatening corneal ulcers in dogs.
Fourteen dogs (17 eyes) of various breeds and ages with deep corneal ulcers were treated surgically with a PRF
membrane transplantation. The corneal ulcer of all the patients was closed with an autologous platelet-rich fibrin
membrane. In the first 10 days after the operation, it was observed that the fibrin membrane partially melted, and
corneal epithelialization and granulation tissue occurred in and around the ulcer area due to the graft material. Pain
was significantly relieved, and conjunctival inflammation was noticeably improved. From the 20th day after the
surgery, the granulation tissue was gradually cleaned. It was determined that all the eyes had vision. The most common
complications after surgery were corneal pigmentation and fibrosis of varying severity. The use of autologous fibrin
membranes is a safe and effective surgical alternative for the closure and healing of corneal ulcers. Our findings show
that the autologous platelet-rich fibrin membrane is useful and effective in treating canine corneal deep ulcers.
