Clinical case:
Congenital retinal macrovessels, where an aberrant retinal vessel, usually a venule, is present in the posterior pole and may cross the avascular foveal region, are seen rarely.
Discussion:
Most of these cases are unilateral and stable with excellent visual prognosis and are detected on routine examination. Foveal cysts, hemorrhag...

Purpose: To report a case of congenital macular macrovessels Case report: An 8-year-old girl was referred for decreased vision in her right eye. Her best corrected visual acuity (BCVA) in the right eye was 20 / 200 and in the left eye 20 / 20 . Anterior segment examinations were normal in both eyes. Posterior segment examination of the right eye sh...

... In 1869, Mauthner was first described congenital retinal macrovessel as "an aberrant retinal vessel". In 1982, Brown et al. [1][2][3][4] formally termed such abnormal vessel as "congenital retinal macrovessel", which presents as unilateral, abnormally large, aberrant retinal vessel and transverses through the foveal avascular region in the posterior region. Such vessel supplies or drains the retina both inferiorly and superiorly to the horizontal raphe. ...
... For some authors, the prevalence of this condition is approximately 1/200,000. 3,4,6 Most congenital retinal macrovessel cases are unilateral and stable with excellent visual prognosis and are detected on routine examination. In rare cases, foveolar cysts, macular hemorrhages, pigmentary changes, serous macular detachment and a displaced fovea may also be seen. ...
Purpose
To present a case of atypical unilateral developmental retinal vascular anomaly.
Observations
A 10-year-old girl presented to her paediatrician after an absent red reflex was noted in a photograph. She had right anisometropic amblyopia and right iris heterochromia, but was otherwise healthy, with no visual complaints. Fundus examination revealed abnormal right retinal vasculature in keeping with an arteriovenous malformation (AVM). OCTA performed at age 16, showed large aberrant veins in the right eye, whereas OCTA B-Scans showed that the same eye had significantly higher retinal blood perfusion than the unaffected eye.
Conclusions and Importance
OCTA is a valuable, non-invasive emerging method of evaluating patients with AVMs, with this patient having a unique unilateral presentation of a developmental anomaly, without evidence of progression or other vessel malformation. OCTA allowed assessment of flow between the affected and non-affected eye, quantifying the greater blood perfusion in the affected eye due to the AVM.
We present an uncommon case of a unilateral congenital retinal macrovessel documented with retinography, perimetry, fluorescein angiography and macular optical coherence tomography. In the case presented the macrovessel crossed the horizontal meridian, between macula and optic disk. A literature review has been performed on congenital retinal macrovessels, possible structural and visual alterations they may cause and their association with other pathologies.
Resumen
Presentamos un caso de macrovaso congénito retiniano estudiado mediante retinografía, campo visual, angiografía fluoresceínica y tomografía óptica de coherencia macular. El macrovaso atravesaba el meridiano horizontal, nasalmente entre papila y mácula. Además, se realiza una revisión de los macrovasos congénitos retinianos, las alteraciones visuales y estructurales que causan su asociación con otras enfermedades y su diagnóstico diferencial.
We report a case of a 35 year old male patient with no medical history, who experienced decreased vision in his left eye that he noticed by chance. After a complete ophthalmic examination, he was diagnosed with congenital retinal macrovessel with macular thickening.
Congenital retinal macrovessels are rare vascular anomalies, in which the diagnosis is usually incidental as their visual impact is minimal. In the rare cases where there is a significant visual impairment, this is due to macular hemorrhages, foveal cysts, serous macular detachment, or the course of the vessel itself through the foveal avascular zone.

Se presenta el caso de un varón de 35 años sin antecedentes de interés que consulta por mala visión del ojo izquierdo objetivada de forma fortuita, en el cual tras un completo estudio se llega al diagnóstico de macrovaso congénito retiniano con engrosamiento macular.
Retinal macrovessel is a rare disease. Since the first description in 1869 by Mauthner, fewer than 30 cases have been reported. We report a case of congenital retinal macrovessel in a 28-year-old patient with no pathological history. The patient consulted for functional macular syndrome (decreased visual acuity, central scotoma). In the right eye, the ophthalmologic examination found a visual acuity of ten over ten and serous detachment of the macular area. Examination of the left eye demonstrated the temporal vein crossing the macular area, without hemorrhage or exudates. Fluorescein angiography confirmed the diagnosis of bilateral central serous chorioretinitis with a congenital retinal macrovessel without leakage or arteriovenous anastomosis. Progression was marked by a disappearance of central serous retinopathy and visual recovery to ten over ten. In light of a literature review, we discuss the clinical classification of this disease and its developmental profile. The etiology of congenital retinal macrovessel is unknown. The diagnosis is clinical; its course is characterized by its stability. Its combination with central serous retinopathy is a fortuitous coincidence more than an individualized clinical form.
