Name of the Condition

• Acute Atopic Conjunctivitis, Unspecified Eye
• Also known as allergic conjunctivitis.

Summary

Acute atopic conjunctivitis is a sudden-onset allergic reaction affecting the conjunctiva, the clear tissue covering the white part of the eye and the inside of the eyelids. It typically results in redness, itching, and tearing. This condition can affect one or both eyes and is often caused by environmental allergens.

Causes

• Exposure to allergens such as pollen, dust mites, pet dander, or mold.
• Sometimes linked to other allergic conditions, like atopic dermatitis and allergic rhinitis.

Risk Factors

• History of allergies or asthma.
• Genetic predisposition.
• Seasonal changes that increase pollen exposure.
• Prolonged exposure to environments with high levels of dust or dander.

Symptoms

• Red, itchy, and watery eyes.
• Swollen eyelids.
• Sensation of burning or gritty feeling in the eyes.
• Watery or sticky discharge, particularly upon waking.

Diagnosis

• Clinical evaluation based on symptoms.
• Review of patient’s allergy history.
• In some cases, an allergist may perform allergy testing to identify specific triggers.

Treatment Options

• Antihistamines: Help reduce itchy and watery eyes.
• Mast cell stabilizers: Prevent the release of allergy mediators.
• Artificial tears: Flush out allergens and provide comfort.
• Corticosteroid eye drops: Used in severe cases to reduce inflammation.
• Avoidance of known allergens when possible.

Prognosis and Follow-Up

• Prognosis is usually good with proper management and treatment.
• Regular follow-up examinations can ensure effective control of symptoms and monitor for potential side effects of medications.

Complications

• Chronic or recurrent conjunctivitis if not managed properly.
• In rare cases, eczema of the eyelids may occur.

Lifestyle & Prevention

• Maintain a clean environment to reduce allergen exposure.
• Use air filters and keep windows closed during high pollen seasons.
• Regularly wash bedding and curtains.

When to Seek Professional Help

• Persistent or worsening symptoms despite treatment.
• Difficulty in seeing or significant changes in vision.
• Severe eye pain or discharge.
