I’ve been taking Arimidex on and off. This time it’s been a few days and I take only 2 drops (about 0.1mg) a day. I noticed my vision becomes blurry and I feel dizzy/spacey. I found this article on the American Academy of Ophthalmology website.
A study by Dr. Eisner and colleagues suggests that anastrozole can cause small retinal hemorrhages in some patients. He said that his research indicates that breast cancer patients who take anastrozole are more likely to have retinal hemorrhages than tamoxifen users. These hemorrhages may be the result of excessive traction on the retina, caused by estrogen depletion. Related effects, such as posterior vitreous detachments, may occur during the natural menopausal transition, he said. Dr. Eisner noted that it’s possible to assess the tractional effects of AIs through the use of OCT. Other possible effects of AIs include photopsia and increased incidence of floaters, as well as dry eye.
I don’t really know if my estrogen is depleted yet and am not sure continuing with Arimidex would be safe. Maybe taking it every other day may help.
