Hemorragia vítrea como causa de pérdida de la visión en una paciente con Dengue / Vitreous hemorrhage as a cause of vision loss in a patient with dengue

RESUMEN

RESUMEN La hemorragia vítrea secundaria a una arteria hialoidea persistente íntegra es una anomalía infrecuente. Se presenta el caso de una mujer de 65 años con antecedentes personales conocidos de esta anomalía congénita en el ojo derecho, la cual presentó disminución de visión de ese ojo de forma repentina, 10 días después de haber presentado cuadro febril agudo con diagnóstico de Dengue. La biomicroscopía posterior reveló una arteria hialoidea persistente rellena de sangre con inserción en la cristaloides posterior. En la oftalmoscopia indirecta se observó una hemorragia vítrea parcial, que permitía visualizar las estructuras de la retina. Se realizaron como pruebas diagnósticas y de seguimiento la ecografía ocular y la retinofoto.

ABSTRACT

ABSTRACT Vitreous hemorrhage secondary to a complete persistent hyaloid artery is an uncommon anomaly. The case of a 65-year-old woman with a known personal history of this congenital anomaly in the right eye is presented, who had a sudden decrease in vision of that eye, ten days after presenting an acute febrile condition with a diagnosis of dengue. Posterior biomicroscopy revealed a persistent hyaloid artery filled with blood with insertion into the lens posterior portion or hyaloid fossa. In indirect funduscopy a partial vitreous hemorrhage was observed, which allowed visualizing the structures of the retina. Ocular ultrasound and retinophoto were performed as diagnostic and follow-up tests. The vitreous hemorrhage was completely reabsorbed at 15 days and the patient recovered her vision at 0.5 due to the presence of an ongoing cataract. There was no recurrence of bleeding in six months' follow-up.
