Hemorragia peripapilar subretinal profunda como complicación asociada a drusen de nervio óptico / Deep subretinal peripapillary bleeding as a complication associated to optic nerve drusen

RESUMEN Los drusen de nervio óptico fueron descritos por primera vez por Liebreich en el año 1868. Otros términos para designar esta entidad incluyen cuerpos hialinos y cuerpos coloides del disco óptico. Tienen una prevalencia de 1 por 500 y el 60 por ciento de los casos se encuentran profundos en la cabeza del nervio óptico. La patogenia primaria de los drusen puede ser una displasia hereditaria del canal óptico del disco óptico y su vasculatura, lo que predispone a la formación de estos. La evolución natural de los drusen es un proceso dinámico que transcurre durante toda la vida. Entre las complicaciones asociadas se presentan defectos de campo visual, pérdida de visión central (rara pero bien documentada), neuropatía óptica isquémica, oclusiones vasculares retinales, pérdidas transitorias de la visión, neovascularización subretinal peripapilar, corioretinopatia serosa central peripapilar y hemorragias pre y peripapilares. Se presenta una paciente de 64 años de edad con antecedente de haber sido operada de desprendimiento de retina del ojo izquierdo, y en el ojo derecho presentaba una hemorragia peripapilar subretinal profunda asociada a drusen(AU)

ABSTRACT Optic nerve drusens were first described by Liebreich in the year 1868. Other terms to designate this condition are optic disc hyaline bodies and colloid bodies. They have a prevalence of 1 per 500 and 60 percent of the cases occur deep in the optic nerve head. The primary pathogenesis of drusens may be an inherited dysplasia of the optic canal of the disc and its vasculature, which leads to their formation. The natural evolution of drusens is a lifelong dynamic process. Associated complications include visual field defects, central vision loss (rare but well documented), ischemic optic neuropathy, retinal vascular occlusion, transient sight loss, peripapillary subretinal neovascularization, central serous peripapillary chorioretinopathy, and pre- and peripapillary bleeding. A case is reported of a 64-year-old female patient with a history of surgery for retinal detachment of the left eye. In the right eye the patient presented deep peripapillary subretinal bleeding associated to drusen(AU)

A Case of Optic Disc Hemorrhage Associated with Buried Optic Nerve Head Drusen

PURPOSE: We report a case of optic disc hemorrhage associated with buried optic nerve head drusen in a pediatric patient. CASE SUMMARY: A 10-year-old female visited our clinic with a floating sensation in her left eye, 2 days in duration. Best corrected visual acuity was 1.0 in both eyes. Intraocular pressure, light reflex, relative afferent pupillary defect and color vision were normal. The patient showed a small optic disc with blurred, irregular margins in both eyes, and optic disc hemorrhage in the left eye on fundus examination. Visual field examination revealed an enlarged blind spot in the left eye. To achieve correct diagnosis, brain MRI was performed and revealed normal findings. On spectral-domain optical coherence tomography (OCT), hyper-reflective and heterogeneous mass like lesions were found with buried optic nerve head drusen. CONCLUSIONS: In general, optic nerve head drusen, has a good prognosis; however, visual field defects or hemorrhagic complications can occur, therefore, correct diagnosis and regular follow-up are necessary.
