The intraocular manifestations of rickettisial retinitis include retinal vasculitis, maculopathy, optic neuritis, and neurosensory detachment. Extensive leakage of dye on the fundus fluorescein angiography may obscure visualization in eyes with retinitis. We report the vascular changes in eyes with rickettsial retinitis and its response to treatment using optical coherence tomography angiography. The microvascular abnormalities we noted were, capillary drop out areas corresponding to retinitis patches, vascular loops, and pruning of vessels. The choriocapillary slabs showed signal void areas. Post-treatment there was vascular remodeling with decrease in non-perfused area, appearance of new vascular lateral branching, and appearance of collaterals.
立克次体性视网膜炎的眼内表现包括视网膜血管炎、黄斑病变、视神经炎和神经感觉脱离。眼底荧光血管造影的广泛染料渗漏可能会使视网膜炎眼的可视化变得模糊。我们报告了立克次体性视网膜炎的血管变化及其对光相干断层扫描血管造影的反应。我们注意到的微血管异常包括与视网膜炎斑块相对应的毛细血管脱落区、血管环和血管修剪。脉络膜板显示信号缺失区。治疗后，无灌注区减少，出现新的血管侧支分支，出现侧支循环，血管重塑。
