Congenital retinal macrovessel: An atypical presentation with low vision and macular thickening

Abstract

Case report

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.

Discussion

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.

Resumen

Caso clínico

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.

Discusión

Los macrovasos congénitos retinianos son una rara anomalía vascular cuyo diagnóstico suele ser casual ya que la repercusión visual es mínima. En los pocos casos en que se produce afectación visual importante, esta se debe a hemorragias maculares, quistes foveales, desprendimiento seroso macular o al propio transcurso del vaso por la zona avascular foveal.
