Psoriasis and Psoriatic Arthritis (PsA)

Psoriasis and Psoriatic Arthritis (PsA) are chronic autoimmune conditions.

Psoriasis

1. A skin condition characterized by red, scaly patches (plaques) on the skin, often on the elbows, knees, and scalp.
2. Can also affect nails, causing pitting, thickening, or separation from the nail bed.

Psoriatic Arthritis (PsA)

1. A type of arthritis that occurs in some people with psoriasis, causing joint pain, stiffness, and swelling.
2. Can affect any joint, but commonly affects hands, feet, knees, and spine.
3. Symptoms may include:

1. Joint pain and stiffness 2. Swelling and redness 3. Reduced range of motion 4. Fatigue 5. Nail changes

Connection between Psoriasis and PsA

1. Both conditions are autoimmune and inflammatory.
2. PsA often develops in people with existing psoriasis.
3. Treatment for both conditions may include topical creams, light therapy, and systemic medications (e.g., biologics, DMARDs).

Management

1. Medications to reduce inflammation and slow disease progression.
2. Lifestyle modifications, such as maintaining a healthy weight, exercising regularly, and managing stress.
3. Collaboration between dermatologists and rheumatologists for comprehensive care.

Common Ocular Manifestations 1. Uveitis: Inflammation of the uvea, which can cause eye pain, redness, and vision problems. 2. Conjunctivitis: Inflammation of the conjunctiva, which can cause redness, itching, and discharge. 3. Dry eye: Reduced tear production or poor tear quality, leading to dry, irritated eyes. 4. Blepharitis: Inflammation of the eyelids, which can cause redness, itching, and crusting. 5. Keratitis: Inflammation of the cornea, which can cause pain, redness, and vision problems. Importance of Monitoring

1. Regular eye exams are crucial for early detection and treatment of ocular manifestations.
2. Collaboration between dermatologists, rheumatologists, and Optometrists/ ophthalmologists is essential for comprehensive care.

Treatment

1. Topical corticosteroids or immunosuppressive medications may be used to treat ocular inflammation.
2. Artificial tears or lubricating ointments can help manage dry eye.

If you have psoriasis or PsA, it's essential to report any eye symptoms to your HCP promptly and with due urgency.
