Abnormal Unilateral Dilated Perifoveal Venule Found During Observation of a Transient Vitreomacular Traction.

This case report describes a new type of perifoveal retinal vascular abnormality (RVA) incidentally discovered during a posterior vitreous detachment (PVD) investigation. A 65-year-old woman with sudden central visual loss displayed a uni-lateral focal telangiectatic venule in the perifoveal area. Multimodal imaging documented the vascular abnormality and associated retinal changes. Despite symptom resolution, the RVA persisted. This case represents a unique presentation of perifoveal RVA, likely an atypical form of macular telangiectasia. The sequential imaging documentation during a process of PVD with central bouquet traction provides insights into the underlying mechanisms in addition to diagnosing and monitoring perifoveal RVAs.
