A Plaquenil eye exam, also known as a hydroxychloroquine (HCQ) retinal exam, is a specialized eye examination performed to monitor the ocular health of individuals who are taking hydroxychloroquine or chloroquine medications, commonly known by the brand names Plaquenil and Aralen, respectively. These medications are often prescribed to manage autoimmune conditions like rheumatoid arthritis, lupus, and certain types of malaria.

Hydroxychloroquine and chloroquine can have potential side effects on the retina, the light-sensitive tissue at the back of the eye. Prolonged use of these medications may increase the risk of developing retinal toxicity, which could lead to permanent vision loss. Regular Plaquenil eye exams are crucial for early detection of any retinal changes and to ensure the safe use of these medications.

Here's what typically happens during a Plaquenil eye exam:

1. Baseline Exam: Before starting hydroxychloroquine or chloroquine treatment, an eye care professional performs a comprehensive eye exam to establish a baseline assessment of the patient's retinal health and overall eye condition.

2. Follow-Up Exams: Once the patient is on the medication, regular follow-up exams are recommended to monitor for any retinal changes. The frequency of follow-up exams varies depending on factors such as the patient's dosage and the duration of medication use.

3. Specific Testing: During the Plaquenil eye exam, several specialized tests may be performed, including:

   • Visual Acuity Test: To assess overall visual function.

   • Amsler Grid Test: To detect any distortions or changes in central vision.

   • Color Vision Test: To check for color vision abnormalities.

   • Fundus Photography: Photographs of the retina are taken for future comparisons.

   • Spectral Domain Optical Coherence Tomography (SD-OCT): This high-resolution imaging technique provides detailed cross-sectional images of the retina, helping to detect any changes.

   • Visual Field Testing: This assesses the patient's peripheral (side) vision, as damage to the retina may affect peripheral vision.

4. Retinal Changes: If any retinal changes are detected during the Plaquenil eye exam, the eye care professional will discuss the findings with the patient and their prescribing physician. Depending on the severity of the changes, treatment adjustments or discontinuation of the medication may be recommended.

It's important to note that the risk of retinal toxicity from hydroxychloroquine or chloroquine is relatively low when the recommended dosage guidelines are followed and proper monitoring is in place. The goal of regular Plaquenil eye exams is to detect any potential issues early, allowing for timely intervention and minimizing the risk of vision loss.

If you are taking hydroxychloroquine or chloroquine for a medical condition, it's crucial to adhere to your prescribed regimen and attend all recommended eye exams to ensure your ocular health is closely monitored.
