PY - 2023 T2 - Current Medical Diagnosis & Treatment 2023 AB - Systemically administered drugs produce a wide variety of adverse effects on the visual system. Table 7–3 lists the major examples. The likelihood of most complications is rare, but if visual changes develop while a patient is being treated with these medications, the patient should be referred to an eye care professional for an eye examination. Screening for toxic retinopathy is recommended at baseline in patients receiving long-term chloroquine or hydroxychloroquine therapy. Screening should occur with automated perimetry and optical coherence tomography macular scans once at baseline. If no baseline abnormalities are present, screening should be repeated annually beginning after 5 years. More frequent screening is necessary in patients treated with doses greater than 5.0 mg/kg real weight/day of hydroxychloroquine or greater than 2.3 mg/kg/day of chloroquine, in patients with kidney disease or in those taking tamoxifen.
