Question

Which of these does NOT feature eye manifestations in association with a seronegative arthropathy?

• A. Psoriasis
• B. Rheumatoid arthritis
• C. Reiter's syndrome
• D. Ankylosing spondylitis

Hint:

Rheumatoid arthritis is seropositive, not part of the seronegative arthropathy family.

Answer 1

The Correct Option is B

Step 1: Recall what a seronegative arthropathy is.
Seronegative arthropathies (seronegative spondyloarthropathies) are a group of joint diseases that share a negative rheumatoid factor, a strong link to the HLA-B27 gene, involvement of the spine and sacroiliac joints, and frequent eye inflammation. The classic members are ankylosing spondylitis, psoriatic arthritis, reactive arthritis (Reiter's syndrome), and arthritis linked to inflammatory bowel disease.

Step 2: Check the eye involvement in each true seronegative arthropathy.
Ankylosing spondylitis commonly causes anterior uveitis (iritis), presenting as a painful red eye.
Psoriatic arthritis, part of the same family, can also cause uveitis and conjunctivitis.
Reiter's syndrome (reactive arthritis) is classically remembered by the triad of arthritis, urethritis, and conjunctivitis or uveitis, so eye involvement is one of its defining features.

Step 3: Examine rheumatoid arthritis.
Rheumatoid arthritis is a seropositive disease in most patients, meaning rheumatoid factor is usually present, and it is not part of the seronegative spondyloarthropathy family at all. It does have its own eye complications, such as scleritis, episcleritis, and dry eyes from secondary Sjogren syndrome, but these come from its own separate immune process, not from being a seronegative arthropathy.

Step 4: Conclude.
Since rheumatoid arthritis does not belong to the seronegative arthropathy group in the first place, it is the one that does not fit the eye disease pattern of that group.

Final Answer:
Rheumatoid arthritis is the condition that does NOT feature eye manifestations as part of a seronegative arthropathy. \[ \boxed{\text{Rheumatoid arthritis}} \]
