H10.13

Clinical Causes: Allergic reactions to environmental allergens like pollen, dust mites, pet dander, or mold Exposure to airborne irritants such as smoke, strong fragrances, or pollution Certain cosmetic products or eye drops containing allergens or irritants Genetic predisposition to atopic dermatitis and other allergic conditions

Key Symptoms: Redness in both eyes Intense itching sensation Swelling of the eyelids and conjunctiva Tearing or watery eyes A sensation of grit or foreign body in the eyes Crusting or discharge around the eyes, especially upon waking Sensitivity to light (photophobia) Mild to moderate discomfort or irritation

Diagnosis Path: Diagnosis of acute bilateral atopic conjunctivitis is primarily clinical, based on a detailed patient history and characteristic signs observed during an eye examination. An eye care professional will look for signs such as bilateral redness, swelling, and itching. To rule out other causes of conjunctivitis (like bacterial or viral infections), additional tests may include conjunctival swabs or allergy testing. Identifying known allergens that trigger symptoms can aid in managing and preventing future episodes.

Treatment Protocols: Treatment strategies focus on alleviating symptoms and minimizing exposure to allergens: - **Allergy avoidance:** Identifying and reducing contact with known triggers - **Use of antihistamine eye drops:** To control allergic reactions and reduce itching - **Artificial tears:** To flush out irritants and soothe the eyes - **Cold compresses:** Applying cool, damp cloths to reduce swelling and discomfort - **Topical corticosteroids:** In severe cases, under medical supervision, to decrease inflammation - **Managing underlying atopic conditions:** Such as controlling eczema or allergic rhinitis It is important to follow guidance from healthcare professionals regarding the use of medications to avoid side effects and ensure effective symptom management.
