A 16-year-old male patient presented to the eye outpatient department for routine ophthalmic evolution. On examination, his best corrected visual acuity was 20/20 in both eyes, and the anterior segment evaluation was remarkably normal. The fundus of the right eye was within normal limits; however, there was the presence of an abnormally prominent aberrant vessel originating from the disc. The vessel after its origin from the disk, coursed around the macula above the horizontal raphe and distributed into multiple small vessels encircling the fovea [Figure 1]. Furthermore, nicking of the vessels was noted and therefore, the patient was counseled for detailed ophthalmic and systemic evaluation. Fundus fluorescein angiography was done which showed the filling of the aberrant vessel in the early phase associated with laminar flow, which was visible even before the filling of the rest of the venous network [Figure 2]. This was suggestive of its venous origin draining into the central retinal vein. Optical coherence tomography of the macula was normal. The patient was evaluated systemically and an MRI brain was done to rule out venous malformation. Fortunately, the patient was systemically fit, and no signs of arteriovenous malformations were found on radiological imaging.

Figure 2: (a and b) Show fluorescein angiography of the left eye with laminar flow in the aberrant vessel without any fluorescence in other retinal veins, suggestive of the venous nature of the aberrant vessel. In (b)the aberrant vessel shows uniform fluorescence, whereas laminal flow can be seen in other retinal veins, suggestive of early filling of the aberrant vessel before the rest of the retinal veins and indicative of an arterio-venous communication/shunt with the aberrant retinal vessel

A congenital retinal macrovessel is an abnormal vessel crossing the central macula with distribution both above and below the horizontal raphe.[1] It was first described by Mauthner, and the term was later coined by Brown et al.[1],[2] It has been reported as a type of arteriovenous malformation (stage 1) with vessel course described as crossing the fovea, encircling the fovea, or bypassing the fovea.[3] Usually, it is a vein, and the patient is asymptomatic. Vision loss can reportedly occur from macular hemorrhage, serous macular detachment, cystoid edema, or vessel crossing the fovea.[4],[5] Pichi et al. reported an association of 24% of retinal macrovessel with brain venous malformation.[3] In our patient, the aberrant vessel was a vein as seen angiographically encircling the fovea without causing any vision loss.
