    A 64-YEAR-OLD woman complained of gradual blurring of vision. Biomicroscopic examination demonstrated no anterior segment abnormalities. She had been taking 20 mg of tamoxifen once daily for 8 years as prophylaxis for a previously excised breast adenocarcinoma. Funduscopy revealed refractile crystalline retinal deposits in both maculae (Figure 1, A and B). The appearances were consistent with a diagnosis of crystalline/tamoxifen retinopathy and treatment was discontinued. At the 1-year follow-up, the fundal appearance was unchanged and visual acuity remained at 6/18. viagra 100 Download PDF When a patient with an eye condition walks into an ophthalmologist’s office, the fact that she has been treated for breast cancer may not raise warning flags for the clinician. But there’s accumulating evidence that ocular conditions such as dry eye, retinopathy, and cataracts may be at least partly due to some breast cancer medications. Only a small percentage of breast cancer patients experience clinically evident ocular side effects from their medications. Nevertheless, because these drugs are so widely used, the related eye conditions may affect many women. The breast cancer medication most commonly identified with ocular side effects is tamoxifen. However, chemotherapy agents, such as 5-fluorouracil (5-FU), can also have ocular side effects. And more researchers are becoming concerned that the drugs known as aromatase inhibitors, which now are often prescribed as adjuvant endocrine therapy, may also have adverse effects on the eye, including small retinal hemorrhages, increased incidence of floaters, and dry eye.

The result is a reduction in DNA synthesis and cellular response to estrogen.

    Tamoxifen is an oral anti-estrogen used in the treatment of breast cancer and recently approved to reduce the incidence of breast cancer in high risk women. As a large clinical trial of tamoxifen has reported an increased risk of cataract, we conducted a study of women with breast cancer to evaluate the association of tamoxifen with cataracts and other eye problems. We attempted to recruit previously interviewed patients who were cases in a population-based case-control study of 2653 women with primary breast cancer diagnosed between 19 at ages 55–72 years in Los Angeles County, California, USA. In November 1997, each case was mailed a questionnaire to ascertain self-reported incidence of eye diseases and Amsler grid test scores. Information from 1297 women aged 57–75 years of age was analyzed. Women reporting treatment with tamoxifen were categorized as standard-term users (4–5 years), short-term users (Standard-term and long-term users of tamoxifen more frequently reported developing cataracts than non-users (18.2%, 21.4% vs. The relative risk was 1.40 (95% confidence interval 0.94–2.10) for standard-term users and 1.70 (1.11–2.59) for long-term users. Tamoxifen use was unrelated to frequency of glaucoma or macular degeneration or to Amsler grid test results.
