Observation on the clinical efficacy of intravitreal injection of Conbercept for the treatment of wet age - related macular degeneration / 国际眼科杂志(Guoji Yanke Zazhi)

ABSTRACT

AIM: To observe the efficacy and safety of intravitreal injection of Conbercept for the treatment of wet age-related macular degeneration( AMD) . METHODS:Retrospective analysis. A total of 20 patients involving 22 eyes were diagnosed of wet AMD and confirmed by routine ophthalmic examination, fundus fluorescein angiography ( FFA ) and optical coherence tomography. All these affected eyes received intravitreal injection of 10 mg/ml of 0. 5mg Conbercept, once monthly, for 3 successive times during the initial treatment. The need for repeated treatment was determined according to patients'disease conditions. The patients were followed up once monthly for ≥6mo. The changes in best corrected visual acuity ( BCVA ) , central retinal thickness ( CRT ) and choroidal neovascularization ( CNV) lesion leakage of the affected eyes before and after treatment were compared and analyzed. RESULTS:Within 1, 3 and 6mo after treatment, the mean BCVA ( logMAR ) of the affected eyes increased when compared with before treatment;the difference was statistically significant(PCONCLUSION: Clinically, intravitreal injection of Conbercept for the treatment of wet AMD can increase visual acuity of the affected eyes. It also can decrease CRT of the affected eyes, and inhibit neovascular leakage. There are no treatment-related adverse reactions.
