Abstract

|
Purpose : To measure venous filling time before the operation PRP(Panretinal photocoagulation), to evaluation Change of before and after PRP as well as relation of variation to PRP and progress of new blood vessels.
Methods : We performed 32 eyes, who had PDR(proliferative diabetic retinopathy) during the operation of PRP patients, before and after PRP in video fluorescein angiogram using SLO(Scanning laser opthalmoscope). To started PRP within 2 weeks after SLO and the PRP to start again after 3-5 months of video fluorescein angiogram using SLO.
Result : Change of venous filling time before and after the PRP decrease -0.99±1.60 second of regreseed group and increase 0.30±1.69 second of complicated group. In the T-test was significant(P < 0.05). Also decrease to angiogenesis of regreseed group and retardation of complicated group to change of venous filling time before and after the PRP in PDR. We suggest that change of venous filling time before and after the PRP is standard to measure effectiveness of PRP.
