Blefaritt

Blefaritt, also known as blepharitis, is a chronic inflammatory condition of the eyelid margins. It is common and typically relapsing rather than a single infection. It affects both sexes and all ages, though it is more frequent in adults and in people with seborrheic dermatitis or rosacea.

Signs and forms: There are two main forms. Anterior blefaritt involves the lash line with crusting, scaling, and redness of the outer lid margin. Posterior blefaritt affects the inner lid margin and Meibomian glands, often with lid margin redness, swelling, and greasy debris. Symptoms may include itching, burning, tearing, foreign body sensation, and morning crusts. Some patients have both forms.

Causes and risk factors: Blefaritt is multifactorial. Bacterial colonization, especially Staphylococcus species, skin conditions such as seborrheic dermatitis or rosacea, contact lens use, and poor eyelid hygiene contribute.

Diagnosis: Diagnosis is based on clinical examination of the eyelid margins. Differential includes conjunctivitis, stye, or dry eye. Cultures or imaging are rarely needed.

Treatment: Management emphasizes lid hygiene: regular warm compresses and daily lid scrubs. For anterior blefaritt, topical antibiotics applied to the lid margin may help for a short period. For posterior blefaritt and Meibomian gland dysfunction, oral antibiotics such as doxycycline or minocycline may be used in chronic cases. Artificial tears can relieve dryness. Avoid irritants and discontinue or modify eye makeup or contact lens use. Refractory cases should be managed by an ophthalmologist; lid margin debridement or specialized therapy may be considered.

Prognosis: Blefaritt is usually a chronic condition with relapses, but symptoms can be controlled with ongoing hygiene and treatment. Potential complications include conjunctivitis, keratopathy, styes, or chalazia if not properly managed.
