bindehinnesår

bindehinnesår, also known as conjunctivitis, is a common inflammation of the conjunctiva, the transparent membrane that covers the white part of the eye and the inner surface of the eyelids. It can affect one or both eyes and is characterized by redness, itching, and a gritty sensation.

The causes of conjunctivitis are varied. Viral infections are a frequent culprit, often accompanying common colds or respiratory illnesses. Bacterial infections can also lead to conjunctivitis, typically presenting with a more pronounced discharge, often thick and yellowish or greenish. Allergic conjunctivitis is triggered by allergens such as pollen, dust mites, or pet dander, and is usually accompanied by watery eyes and sneezing. Irritant conjunctivitis can occur due to exposure to smoke, chlorine in swimming pools, or foreign objects in the eye.

Symptoms of bindehinnesår commonly include redness of the eye, a watery or thick discharge, itching, burning, and a feeling that something is in the eye. In some cases, light sensitivity and blurred vision may also be present.

Diagnosis is usually made based on a physical examination and a review of symptoms. Treatment depends on the underlying cause. Viral conjunctivitis often resolves on its own within a week or two, with supportive care like cool compresses. Bacterial conjunctivitis is treated with antibiotic eye drops or ointments. Allergic conjunctivitis can be managed with antihistamine eye drops or oral medications, and by avoiding known allergens. Irritant conjunctivitis typically resolves once the irritant is removed. Good hygiene, such as frequent handwashing, is important to prevent the spread of infectious conjunctivitis.
