RESUMO
CASE REPORT: A fifty-five year old man complained of diminished visual acuity in his right eye and reported a deep venous thrombosis in his right leg five years ago. Examination showed a central retinal vein occlusion in the right eye. Mutations in the factor V gene and prothrombin gene were found in a thrombophilia study. The patient was anticoagulated and no laser photocoagulation was required. DISCUSSION: Various coagulation disorders induced by genetic mutations are often associated with an increased risk for retinal vein occlusion although there are no statistically significant associations reported in the literature.

CASE REPORT: A thirty year-old-woman that had received radiotherapy three years before for a frontal glyoma consulted because of diminished visual acuity in her left eye. Examination showed a proliferative radiation retinopathy in the left eye and non-proliferative radiation retinopathy in the right eye that was confirmed by fluorescein angiography. The patient was treated with panretinal photocoagulation, and her visual acuity remained stable. DISCUSSION: Patients receiving cranial or neck radiotherapy should be followed for long periods of time because radiation retinopathy may appear many years after the treatment. Follow-up may permit early diagnosis of ischemic radiation retinopathy that can benefit from laser photocoagulation.

Caso Clínico: Mujer de treinta años, tratada con radioterapia por un glioma frontal tres años atrás, que refería déficit de agudeza visual en el ojo izquierdo (OI). Presentaba una retinopatía isquémica proliferante en OI y no proliferante en el derecho, lo cual fue confirmado mediante angiografía fluoresceínica. La paciente fue panfotocoagulada, quedando estabilizada la agudeza visual. Discusión: La retinopatía por radiación puede aparecer muchos años después de aplicada ésta, por lo que los pacientes que reciben radioterapia de cabeza y cuello deben ser controlados para detectarla precozmente ya que se pueden beneficiar del tratamiento con láser (AU)
