Abstract:
Objective To investigate the healing mechanism of the rabbit's selerotomy sites undergoing the transconjunctival su- tureless vitrectomy(TSV),and to compare the wound healing effect of the different surgery procedures.Design Experimental study. Participants New Zealand white rabbits.Methods Thirty-two New Zealand white rabbits were divided into four groups:the core vitrec- tomy and fluid-air exchange (Group A),the core vitrectomy (Group B),the non-core vitrectomy and fluid-fir exchange (Group C) and the non-core vitrectomy(Group D).Intraocular pressure(IOP)was measured on the day preoperatively and the day 1,3,5,7,14 postopera- tively with Tonopen tonometers.Sclerotomy sites were investigated with the ultrasound biomicroscope(UBM)on the day 1,5 and 9 postoperatively,and the internal and the external diameter of the wound was estimated on the day 1 postoperatively.The pathological sections of the sclerotomy sites on the day 3,5 and 9 postoperatively were observed under the light microscope.Main Outcome Mea- sures IOP,the internal and external diameter of the wound.Results The IOP of Group A was obviously higher than the other groups on the day 1 postoperatively (P
