ABSTRACT
OBJECTIVE@#To examine the effect of genistin on traumatic proliferative vitreoretinopathy (PVR) in rabbits.@*METHODS@#Traumatic PVR was induced in pigmented rabbits by intravitreal injection of platelet rich plasma. The eyes then received an intravitreal injection of dimethyl sulfoxide (0.1 mL), 2 or 40 μg genistin (0.1 mL), and 1 mg fluorouracil(0.1 mL), respectively to form 4 groups. The eyes were examined ophthalmoscopically on distinct days after the surgery and the stage of PVR was evaluated. The model eyes and normal eyes in the 40 μg genistin group carried ERG test on the 28th day. All model eyes in the 4 groups were observed by light microscope on the 28th day.@*RESULTS@#In the control eyes, the retina was detached after 10 d, the PVR had progressed to higher stages with time. In the eyes injected 40 μg genistin or fluorouracil, the PVR also developed; however, the severity of PVR was lower than that in the control eyes. PVR was significantly inhibited in the 40 μg genistin group compared with the control eyes after 14 d (P<0.05). Histological examination of the genistin-treated eyes disclosed no morphological changes, and ERG analysis revealed no significant functional changes.@*CONCLUSION@#Intravitreal injection of genistin is safe and effective in reducing traumatic PVR in clinical treatment.
