To describe composite multicolour (MC) imaging features along with the monocoloured fundus reflectance images in active and resolving stages of post-fever retinitis (PFR).
Retrospective image analysis of cases of PFR who underwent dilated retinal clinical examination followed by optical coherence tomography and MC imaging.
Twenty-five eyes of 18 patients diagnosed with PFR were included. There were 11 males and 7 females. Mean age of patients was 30.63 years. The retinitis lesion appeared bright white on MC image and white mainly on blue and green reflectance images during the active stages of PFR. The lesion appeared dull-grey to greyish white during the resolving stages and as dull-green in resolved cases. The active stages showed the presence of intraretinal/subretinal fluid which appeared as green colour on MC images and less green to normal during resolving stages. Hard exudates were seen as bright yellow- or orange-coloured spots on MC image during the resolving stages of the disease.
The different stages of PFR show different colour on multicolour image and different reflectance patterns on individual colour reflectance channels. Hence, multimodal fundus imaging with different wavelength can be helpful for differentiation of activity in PFR.
描述发热后性视网膜炎（PFR）活动期和消退期的复合多色（MC）成像特征以及单色眼底反射图像。
对接受扩瞳视网膜临床检查、光学相干断层扫描和 MC 成像检查的 PFR 患者进行病例回顾性图像分析。
纳入 18 例 25 眼 PFR 患者，男 11 例，女 7 例，年龄 30.63 岁。在 PFR 的活动期，MC 图像上病变呈亮白色，蓝、绿反射图像上主要呈白色。在消退期，病变呈暗灰色到灰白色，在消退期呈暗绿色。活动期显示视网膜内/下液，MC 图像上呈绿色，在消退期呈绿色到正常。在疾病的消退期，可以在 MC 图像上看到硬性渗出物呈亮黄色或橙色斑点。
PFR 的不同阶段在多色图像上呈现不同的颜色，在各个颜色反射通道上呈现不同的反射模式。因此，不同波长的多模态眼底成像有助于 PFR 活动的鉴别。
