Allergic shiner is a term used to describe the dark circles that appear under the eyes as a result of allergic rhinitis or other allergic reactions. These dark circles are caused by the congestion of the small blood vessels beneath the skin in the area around the eyes.

Causes

Allergic shiners are primarily caused by nasal congestion associated with allergies. When an individual is exposed to an allergen, the body's immune system reacts by releasing histamines, which cause the blood vessels to dilate and become more permeable. This leads to the accumulation of fluid and blood in the tissues under the eyes, resulting in a darkened appearance.

Symptoms

The primary symptom of allergic shiners is the presence of dark circles under the eyes. These circles may appear bluish or purplish and are often accompanied by other symptoms of allergic rhinitis, such as:

• Sneezing
• Nasal congestion
• Runny nose
• Itchy eyes
• Watery eyes

Diagnosis

The diagnosis of allergic shiners is typically made based on the patient's medical history and a physical examination. A healthcare provider may inquire about the presence of other allergy symptoms and any known allergen exposures. In some cases, allergy testing may be performed to identify specific allergens.

Treatment

The treatment of allergic shiners involves managing the underlying allergic condition. This may include:

• Avoiding known allergens
• Using antihistamines to reduce allergic symptoms
• Applying nasal corticosteroids to decrease inflammation
• Utilizing decongestants to relieve nasal congestion
• Implementing allergen immunotherapy (allergy shots) for long-term relief

Prevention

Preventing allergic shiners involves minimizing exposure to allergens and managing allergic symptoms effectively. Strategies may include:

• Keeping windows closed during high pollen seasons
• Using air purifiers to reduce indoor allergens
• Regularly cleaning bedding and upholstery to remove dust mites
• Avoiding contact with pets if allergic to animal dander
