目的探讨急性视网膜中央静脉阻塞（acute central retinal vein occlusion，CRVO）患者眼底超宽视野（Ultra-widefield，UWF）红通道图像显示的视网膜出血与灌注状态的关系。使用绿色和红色通道图像定量计算视网膜出血，产生绿色通道出血（GCH）和红色通道出血（RCH）。每只眼睛的非灌注面积（NPA）也由荧光素血管造影计算。GCH和RCH与NPA之间的关系进行了调查。结果32例急性CRVO患者（男18例，女14例）的32只眼。平均GCH和RCH值分别为10.4% ± 8.2%和1.7% ± 1.7%。平均NPA为39.2% ± 28.8%。GCH与NPA（r= 0.38;P= 0.022）和RCH与NPA（r= 0.44;P= 0.010，线性回归分析）之间存在显著相关性。多因素分析表明，只有RCH与NPA.ConclusionsRetinal出血检测UWF红通道成像相比，绿色通道成像较少，与视网膜NPAs密切相关的急性CRVO眼睛。UWF红通道成像使我们能够识别缺血相关的出血。
PurposeTo evaluate the relationship between retinal haemorrhages detected on Ultra-widefield (UWF) red channel images and perfusion status in eyes with acute central retinal vein occlusion (CRVO).MethodsUWF fundus images were split into green and red channels using ImageJ software. The retinal haemorrhages were calculated quantitatively with both the green and red channel images, resulting in green channel haemorrhages (GCH) and red channel haemorrhages (RCH). The nonperfusion area (NPA) was also calculated from fluorescein angiography in each eye. The relationships between both the GCH and RCH with the NPA were investigated.ResultsThirty-two eyes of 32 patients with acute CRVO (18 men, 14 women) were included. The mean GCH and RCH values were 10.4% ± 8.2% and 1.7% ± 1.7%, respectively. The mean NPA was 39.2% ± 28.8%. Significant correlations were seen between the GCH and NPA (r= 0.38;P= 0.022) and RCH and NPA (r= 0.44;P= 0.010, linear regression analysis). Multivariate analysis suggested that only the RCHs were correlated significantly with the NPA.ConclusionsRetinal haemorrhages detected by UWF red channel imaging were less compared to green channel imaging and associated closely with retinal NPAs in eyes with acute CRVO.UWF red channel imaging allowed us to identify ischaemia-related haemorrhage.
