Hydroxychloroquine (Plaquenil) Eye Screening in Baltimore: Why Regular Retinal Exams Matter
Hydroxychloroquine, commonly known by the brand name Plaquenil, is an important medication used to treat autoimmune diseases such as lupus, rheumatoid arthritis, and Sjögren’s syndrome. While hydroxychloroquine is highly effective and often life-changing for many patients, long-term use can sometimes affect the retina and potentially cause permanent vision damage if not detected early.
At Precision Eye Care in Baltimore, we provide advanced hydroxychloroquine retinal toxicity screening using state-of-the-art retinal imaging technology, including Optical Coherence Tomography (OCT) and fundus autofluorescence (FAF), to help detect early retinal changes before vision loss occurs.
What Is Hydroxychloroquine Retinal Toxicity?
Hydroxychloroquine retinal toxicity occurs when the medication slowly damages the light-sensitive retinal tissue inside the eye, particularly the macula, which is responsible for central vision.
Early retinal toxicity usually causes no symptoms. Patients may continue seeing normally while microscopic retinal damage is already developing. If toxicity progresses undetected, it can eventually lead to:
- Permanent blind spots
- Difficulty reading
- Distorted vision
- Loss of central vision
- Difficulty driving
- Advanced retinal damage known as bull’s-eye maculopathy
Because retinal toxicity may not be reversible, early detection is extremely important.
New 2026 American Academy of Ophthalmology Guidelines
The newest American Academy of Ophthalmology (AAO) recommendations emphasize earlier and more advanced retinal screening for patients taking hydroxychloroquine.
The updated guidelines now recommend:
- Baseline retinal examination soon after starting hydroxychloroquine
- Annual retinal screening for many patients
- Advanced retinal imaging with OCT and fundus autofluorescence (FAF)
- Careful monitoring of high-risk patients
The guidelines also highlight that retinal toxicity may develop suddenly after years of stable exams, making consistent follow-up essential.
Why OCT Retinal Imaging Is So Important
Optical Coherence Tomography (OCT) is now considered one of the primary tools for detecting early hydroxychloroquine retinal toxicity.
OCT technology creates high-resolution cross-sectional images of the retina and allows ophthalmologists to identify microscopic structural changes long before noticeable vision loss develops.
At Precision Eye Care, our advanced OCT retinal imaging can help identify:
- Early retinal thinning
- Ellipsoid zone disruption
- Outer retinal changes
- Macular abnormalities
- Progression over time
Modern OCT imaging allows earlier diagnosis and safer long-term monitoring for patients taking Plaquenil.
Fundus Autofluorescence (FAF) Imaging
The newest guidelines also emphasize the importance of wide-field fundus autofluorescence imaging (FAF). FAF technology helps detect metabolic changes in the retinal pigment epithelium and may reveal retinal toxicity patterns that are difficult to see on routine examination.
FAF is especially useful because some patients may develop retinal toxicity outside the central macula, particularly patients of Asian or African American descent.
At Precision Eye Care, advanced retinal imaging allows comprehensive evaluation for both parafoveal and pericentral toxicity patterns.
Who Is at Higher Risk for Plaquenil Toxicity?
Several factors increase the risk of hydroxychloroquine retinal toxicity, including:
- Long-term hydroxychloroquine use
- Higher daily dosage
- Kidney disease
- Tamoxifen use
- Older age at medication initiation
- Underlying retinal disease
The AAO currently recommends maintaining hydroxychloroquine dosage at less than or equal to 5 mg/kg/day of real body weight whenever possible.
Patients with lupus, rheumatoid arthritis, sarcoidosis, or other autoimmune conditions should discuss appropriate retinal monitoring with both their rheumatologist and ophthalmologist.
Symptoms of Hydroxychloroquine Retinal Toxicity
Many patients with early toxicity have no symptoms at all. This is why annual eye screening is so important.
As toxicity progresses, symptoms may include:
- Difficulty reading
- Missing spots in vision
- Distorted central vision
- Trouble adjusting to dim lighting
- Reduced color vision
- Blurred central vision
Because vision changes may appear late in the disease process, screening before symptoms occur is critical.
