Spontaneous Resolution of Macular Edema with Abnormal Vessel Crossing near the Central Macula by Congenital Retinal Macrovessel

Abstract

We present a case of a congenital retinal macrovessel (CRM) with spontaneous resolution of cystoid macular edema. A 39-year-old woman with sudden decreased vision in her right eye was referred to our clinic and found to have a CRM with macular edema. Her visual acuity was 20/25. A week later, the macular edema disappeared without any treatment, and her visual acuity was 20/15. We performed optical coherence tomography angiography and fluorescein angiography (FA), which revealed no obstruction of retinal flow but a slight disturbance of retinal flow near the central fovea on FA. We encountered a case of spontaneous resolution of macular edema with abnormal vessel crossing near the central macula by a CRM, and multimodal imaging was useful for investigating the pathology of the disease.

Figures

Fig. 1
Color fundus photography (a) and OCT angiography (b) show a large macrovessel extending within the vascular arcade from an inferior nasal vein, crossing the central macula above the horizontal raphe. c Macula edema is detected on OCT. OCT, optical coherence tomography.

Fig. 2
Color fundus photography (a) and FA (b) a week later. FA shows a branch from the macrovessel without leakage, blockage, or obstruction of retinal flow. c OCT a week later shows resolution of cystoid macular edema. FA, fluorescein angiography; OCT, optical coherence tomography.

a FA overlayed on OCT mapping. Macula edema on OCT corresponds to the area where the CRM crosses the fovea. b Macula edema area enlarged on FA. Vein branching from the CRM (blue arrow) and a retinal artery (red arrow) are crossing and compressed by the CRM (*). Both vessels are narrowing after crossing the CRM (arrowhead). FA, fluorescein angiography; OCT, optical coherence tomography; CRM, congenital retinal macrovessel.
