Certain medications have been known to cause some unusual ocular side effects. Therefore, it's important that we know what medications you take, as it may help guide the testing that we perform during your exam. I will give you 3 examples:
1) Plaquenil, commonly used to treat arthritis, lupus, and malaria, can cause "bulls eye maculopathy," a condition affecting the retina that can lead to central vision loss.
2) Amiodarone, used to treat arrhythmia, can cause "whorl keratopathy," affecting the cornea.
3) Prednisone can cause early-onset cataracts (see pic below) and/or glaucoma.
