In the present study, we investigated the efficacy of vitreous humour and synovial fluid on avulsion wound healing in a rabbit’s model. The vitreous humour is a fluid that resembles gel consisting of approximately ۹۸–۹۹% water, little hyaluronic acid, glucose, collagen, anions, cations and ions. It is in the posterior eye chamber for the comparison with synovial fluid that consisted of hyaluronin, lubricin, proteinase, prostaglandins and collagenase. In this study, both synovial fluid and vitreous humour were collected from rabbits by aspiration of vitreous humour from the eye (postmortem) and arthrocentesis procedure was applied for collection of synovial fluid. Twelve adult rabbits were used in this study, they divided into three groups each group consisted of four animals wounded experimentally (an avulsion wound). Our results showed the influence of vitreous humour (group B) on healing of the wound is better than the synovial fluid (group C) in the clinical evaluation of shrinkage of the wound. The histo-pathologically changes also revealed that in the vitreous humour treated group (group B), the wound healing process proceeded better than other groups (control and synovial fluid groups). In conclusion, the histopathological and clinical observations demonstrated that application of vitreous humour on wound might be pivotal in improving the healing of avulsion wounds and establish a new tissue in rabbits.
