Radiation retinopathy vs. ocular ischemic syndrome: how to reach the diagnosis?

ABSTRACT

We present a case of diagnostic interest; we present the differential diagnosis and the complementary tests necessary to reach it, in addition to highlighting the importance of a correct collection of background and clinical history. A 54-year-old woman with a history of carcinoma of the floor of the mouth treated with radiotherapy and chemotherapy develops ischemic retinopathy. It was necessary to perform a systemic study and differential diagnosis with entities such as ocular ischemic syndrome and radiation retinopathy, due to the similarity in the clinical findings found. Radiation retinopathy should be ruled out in any patient with visual impairment and a history of radiotherapy treatment. A broad differential diagnosis and systemic study are required to rule out entities such as ocular ischemic syndrome and diabetic retinopathy, in addition to early treatment to avoid possible complications.
