Prevent effect of Bevacizumab and Triamcinolone acetonide on corneal neovascularization induced by penetrating keratoplasty

AIM: To observe the clinical effect subconjunctival bevacizumab and triamcinolone acetonide(TA)on corneal neovascularization(CNV)induced by penetrating keratoplasty.METHODS: Nineteen patients(20 eyes)with CNV induced by penetrating keratoplasty after 3mo were selected and were divided into 4 groups randomly: Group A was control group, group B was treated by subconjunctival of bevacizumab(2.5mg, 0.1mL), group C was treated by subconjunctival of bevacizumab(2.5mg, 0.1mL)and TA(4mg, 0.1mL), group D was treated by subconjunctival of TA(4mg, 0.1mL), one time each month, twice.RESULTS: The average follow-up period was 3a. Visual acuity of groups B and C kept stable or increase slightly. CNV and immunologic rejection were lighten(PCONCLUSION: Treatment of subconjunctival bevacizumab and TA can effectively inhibite CNV and immunologic rejection, also has the therapeutical effect to maintain implant transparence after penetrating keratoplasty.
