中心性浆液性脉络膜视网膜病变同步造影中眼底血管充盈状态的探讨

Discussion about Filling State of Eyeground Vein in Simultaneous Angiography in Central Serous Chorioretinopathy

目的观察和分析中心性浆液性脉络膜视网膜病变(centeral serous chorioretinopathy,CSC)患者荧光素钠和吲哚青绿眼底血管同步造影中脉络膜、视网膜血管的早期充盈特点。方法用海德堡眼底血管造影仪对23例CSCR患者行荧光素眼底血管造影(FFA)和吲哚青绿眼底血管造影(ICGA),并分别观察FFA和ICGA中视网膜、脉络膜动脉的充盈时间。结果 23例患者(23眼)眼底血管的早期充盈状态有两种形式:12例患者脉络膜动脉的充盈在ICGA中早于视网膜中央动脉,在FFA中却晚于视网膜中央动脉;11例患者脉络膜动脉的充盈在ICGA和FFA中均晚于视网膜中央动脉。两种充盈状态下ICGA和FFA中脉络膜动脉充盈时间、视网膜动脉充盈时间差异均有统计学意义(P<0.05)。结论 CSC患者眼底血管的早期充盈状态中充盈倒置现象的发生与脉络膜及视网膜血流动力学异常有关。

Objective To take advantage of fundus fluorescein angiography（FFA） and indocyanine green angiography（ICGA） to observe and analyse early filling characteristics of the retina and ehoroid blood vessels in patients with centeral serous chorioretinopathy（CSC）. Methods FFA and ICGA were performed on 23 patients with CSC at the same time with Heidelberg retina angiography, then observing the filling time of the retina and ehoroid blood vessels in FFA and ICGA respectively. Results We observed two forms of retinal and choroid blood vessels in the early filling state in 23 patients （23 eyes） ： In simultaneous angiography, 12 patients＇ filling time of the choroid blood vessels before the retina＇ s in ICGA but l~ ~J the retina＇ s in FFA. filling time of the choroid blood vessels late the retina＇ s in 11 patients. The difference of and retinal artery filling time in 1CGA and FFA in two kinds of filling condition had statistical significance （P 〈 0.05 ）. Conclusion The choroid blood vessels＇ s filling time is late the retina＇ s in CSC patients. This phenomena are related to the choroid and retinal hemodynamic abnormalities.
