Which routine diagnostic screening should a patient with chronic RA on hydroxychloroquine undergo?

Patients with chronic rheumatoid arthritis (RA) who are taking hydroxychloroquine need to undergo regular eye exams. Hydroxychloroquine is associated with potential retinal toxicity, which can lead to vision problems if not monitored appropriately. The drug can cause damage to the retina, which may not become apparent until significant damage has occurred. Therefore, ophthalmologic evaluations are essential to catch any early signs of toxicity or retinal damage. Regular eye exams allow for early detection and management of any issues that could arise from hydroxychloroquine use, making it a necessary component of routine screening for these patients.

While vision tests may assess visual capabilities, they do not specifically monitor the potential toxic effects of hydroxychloroquine on the retina. Chest X-rays and blood glucose tests are not routine screenings related to the specific side effects of hydroxychloroquine. Thus, the emphasis on regular eye exams is crucial in ensuring the safety and effectiveness of treatment.
