	[[File:Allergic_shiner_in_pediatric_patient.png\|thumb\|Allergic_shiner_in_pediatric_patient.png]] '''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 ==		== 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.

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
