Effect of silicone oil on corneal endothelium of rabbit eyes / 吉林大学学报(医学版)

ABSTRACT

Objective To investigate the effect of silicone oil on the corneal endothelium in experimental animal models,while the silicone oil in the anterior chamber of the experimental animals will be taken out so as to explore their corneal changes.Methods Forty healthy white rabbits were randomly divided into three groups silicone oil in the anterior chamber group (SIG),silicone oil in and out of the anterior chamber group (SIOG) and control group(CG).The cornea of rabbit was investigated at different times by slit-lamp,corneal thickness instrument,endothelial cell count instrument,histology and electromicroscopy.The time of silicone oil in the anterior chamber without keratpathy and the pathological changes of cornea with taking out of the silicone oil were observed.Results The density of the corneal endothelium in SIOG and SIG decreased more obviously by endothelial cell count instrument from 8 weeks to 16 weeks compared with control group (P
