Tratamiento de úlceras corneales con plasma rico en plaquetas

Abstract

ObjectiveTo assess the efficacy of platelet rich plasma (PRP) in the treatment of extensive corneal ulcers in albino rabbits. MethodsNew Zealand rabbits, divided in 3 groups, were used for the study. Corneal ulcers of 10mm diameter were made. Rabbits blood was extracted for the preparation of the PRP of the corresponding group. The blood was processed by differential centrifugation. The first group, named control, was treated with sterile saline every 8h. The second group, named gel, was treated with deproteinized extract gel beef fat every 8h, and the third group, named PRP received one PRP drop on the first and third day of monitoring. The rabbits were monitored, by taking photographs, each day for the 7 days that the study lasted. ResultsA better outcome was observed in the group with deproteinized extract gel beef fat (GE group), and the PRP group (PL group), in comparison with the control group (CO group) (P<.05). ConclusionThe PRP showed to be just as effective as the commercial product (Solcoseryl®), for the regeneration of the extensive and deep corneal ulcers. Besides, it stands out as a no surgical procedure is required, and there is easy access, low cost and reduced doses.
