Congenital retinal macrovessel is generally the presence of unilateral aberrant vessel crossing over the horizontal raphe through the macula. Typically, visual acuity is unaffected, although in rare cases, macular hemorrhage, foveolar cysts, foveal contour impairment, and the presence of anomalous vessel in the foveola can affect the vision. In our case, visual acuity of the right eye was counting fingers at 3 meters. He had four diopter oblique astigmatism, esotropia, and dissociated vertical deviation. Fundoscopy revealed a aberrant vein crossing the foveola. Spectral OCT examination showed hiperreflectivity of the vessel and fluorescein angiography showed no leakage of the vessel. Although in the literature it is specified that the aberrant vein crossing the fovea is a factor of lowering visual acuity, in our case we thought, low visual acuity is due to deep amblyopia.
