Use of the n-butyl cyanoacrylate adhesive and the polyglactine thread suture for corneal rhaphy in rabbit (Oryctolagus cunicullus)

Abstract

The aim of this study was to evaluate the cicatricial repair of perforated cornea in rabbits, by using the N-butyl cyanoacrylate adhesive compared to the 910-polyglactine nº 7-0 thread suture through macroscopic and histological assays. Corneas from 18 adult rabbits were perforated and soon after submitted the synthesis with N-butyl cyanoacrylate synthetic adhesive right ocular globe or by simple interrupted sutures using the 910-polyglactine thread left ocular globe. The animals were separate in three groups of the same number. Examination after 7, 15, and 30 days post-operative showed that both the synthetic adhesive and the suture were efficient in the synthesis of the surgical wounds, thus stabilizing the intra-ocular contents. The N-butyl cyanoacrylate adhesive was showed to be superior to the 910-polyglactine suture thread with regards to the evolution and the organization of the healing process.
