title: Hemicentral retinal artery occlusion in a breast cancer patient using anastrozole.
abstract: BACKGROUND
  Anastrozole, an aromatase inhibitor, is commonly used in the adjuvant treatment of breast cancer. Anastrozole treatment is associated with a risk of thromboembolic events and retinal vascular side effects. Herein, we present a case of hemi-central retinal artery occlusion diagnosed in a breast cancer patient using anastrozole.
  
  
  METHODS
  A 53-year-old woman with a hypertensive and diabetic background was admitted to our hospital with breast cancer. Anastrozole treatment was started after surgery, adjuvant chemotherapy, and radiotherapy. Sudden painless loss of vision in the patient's right eye occurred within 13 months of Anastrozole treatment. A fluorescein angiogram revealed hemi-central retinal artery occlusion.
  
  
  CONCLUSIONS
  To the best knowledge of the authors, this is the first report of hemi-central retinal artery occlusion in an anastrozole user.
