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

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.
