Rheumatoid Arthritis (RA)
Rheumatoid arthritis is a chronic, systemic autoimmune disease that primarily affects the joints, leading to inflammation, pain, and eventual joint destruction. It can also have extra-articular manifestations affecting other organs.
📚Pathogenesis
1. Genetic Predisposition:
- Certain genetic factors, such as the presence of HLA-DR4, increase susceptibility to RA.
2. Immune System Activation:
- Autoimmune response targets synovial tissue, leading to chronic inflammation.
- Activated T cells, B cells, and macrophages release pro-inflammatory cytokines like TNF-alpha, IL-1, and IL-6.
3. Synovial Inflammation:
- Inflammation causes synovial hyperplasia (pannus formation) and increased vascularity.
- Pannus invades and erodes cartilage and bone.
4. Joint Damage:
- Persistent inflammation leads to destruction of cartilage and bone, causing deformities and loss of joint function.
- Osteoclast activation and bone resorption contribute to bone erosion.
🎯 Clinical Features
- Joint Symptoms:
- Symmetrical joint involvement, typically affecting small joints of the hands and feet.
- Pain, swelling, warmth, and stiffness, especially in the morning or after inactivity.
- Deformities such as ulnar deviation, swan-neck deformity, and boutonnière deformity.
- Systemic Symptoms:
- Fatigue, fever, and weight loss.
- Extra-articular Manifestations:
- Rheumatoid nodules, especially on pressure points.
- Pulmonary involvement (pleuritis, interstitial lung disease).
- Cardiac involvement (pericarditis, increased risk of atherosclerosis).
- Ocular involvement (scleritis, keratoconjunctivitis sicca).
- Vasculitis and skin manifestations.
👨⚕️Diagnosis
- Clinical Evaluation:
- History and physical examination focusing on joint involvement and systemic symptoms.
- Laboratory Tests:
- Rheumatoid factor (RF): Positive in about 70-80% of patients.
- Anti-cyclic citrullinated peptide (anti-CCP) antibodies: More specific for RA.
- Elevated erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP): Indicators of inflammation.
- Imaging:
- X-rays: Show joint erosion and narrowing of joint spaces.
- MRI and ultrasound: More sensitive in detecting early joint changes and inflammation.
👨⚕️Treatment
- Pharmacologic:
- Nonsteroidal Anti-inflammatory Drugs (NSAIDs):
For pain relief and reducing inflammation.
- Corticosteroids:
For quick control of inflammation during acute flares.
-
Disease-Modifying Antirheumatic Drugs (DMARDs):
- Methotrexate, sulfasalazine, leflunomide.
- Biologic DMARDs: TNF inhibitors (e.g., etanercept, adalimumab), IL-6 inhibitors (e.g., tocilizumab), and others.
- JAK Inhibitors: Tofacitinib, baricitinib.
- Non-Pharmacologic:
- Physical therapy to maintain joint function and muscle strength.
- Occupational therapy to aid in daily activities.
- Lifestyle modifications: Balanced diet, regular exercise, smoking cessation.
- Surgical:
- Synovectomy, tendon repair, joint replacement in severe cases.

- Symptoms may include shifting pains, worse at night, and a general aggravation from damp weather.
- The patient may exhibit intense anxiety, restlessness, and a desire for fresh air.

Corneal Opacity
Corneal opacity refers to any condition that causes the cornea, the transparent front part of the eye, to become cloudy or opaque. This condition can significantly impair vision, depending on the extent and location of the opacity.
👁 Aetiology
Corneal opacity can result from various causes, including:
- Infections:
- Bacterial, viral, fungal, or parasitic keratitis.
- Trachoma caused by Chlamydia trachomatis.
- Herpes simplex keratitis.
- Trauma:
- Physical injuries to the eye, such as abrasions, lacerations, or chemical burns.
- Inflammatory Conditions:
- Autoimmune diseases like rheumatoid arthritis or systemic lupus erythematosus.
- Keratoconus, which leads to thinning and cone-like protrusion of the cornea.
- Degenerative Diseases:
- Fuchs' endothelial dystrophy.
- Pterygium, where abnormal tissue growth extends onto the cornea.
- Nutritional Deficiencies:
- Vitamin A deficiency, which can cause xerophthalmia and night blindness.
- Congenital Disorders:
- Genetic conditions such as congenital hereditary endothelial dystrophy (CHED).
🗨 Clinical Features
- Visual Impairment:
Blurred vision or reduced visual acuity.
- White or Grey Spots:
Visible spots or patches on the cornea.
- Pain:
Depending on the cause, there may be eye pain or discomfort.
- Redness:
Inflammation of the eye.
- Photophobia:
Sensitivity to light.
- Tearing:
Excessive tearing or discharge.
- Foreign Body Sensation: Feeling of something in the eye.
👀 Types of Corneal Opacity
- Nebula:
A faint opacity causing slight vision impairment.
- Macula:
A moderate opacity causing noticeable visual impairment.
- Leukoma:
A dense, white opacity causing significant vision loss.
😎 Treatments
- Medical Treatment:
Antibiotics/Antifungals/Antivirals:
To treat underlying infections.
