The immune system plays a pivotal role in ocular allergies, with different immune responses eliciting a variety of symptoms. These immune responses are initiated by factors located in the conjunctiva, which in turn recruit eosinophils, basophils, and T lymphocytes. Furthermore, certain cells in the cornea can contribute to mounting allergic inflammation.
Allergic conjunctivitis is a hypersensitive condition that affects the conjunctiva, cornea, and lid. It can occur during a specific season or may be ongoing all year long. Some medications can trigger seasonal or perennial allergic conjunctivitis, and can be more severe in some patients.
The most effective treatments for ocular allergies are topical drugs, which are applied as eyedrops directly to the surface of the eye. These methods are noninvasive and reduce the risk of side effects by delivering the medication directly to the eyes. In addition, topical medications do not travel through the body, as oral medications do. More info : https://invisioncommunity.co.uk/what-are-ocular-allergies/
The main way to prevent ocular allergies is to avoid the allergen that causes the symptoms. Your eye care professional can determine the substances that trigger your allergies and prescribe environmental control measures to minimize your exposure to them. Symptoms of ocular allergies include itchiness, tearing, redness, and a burning sensation in the eye. In severe cases, you may also experience fatigue.
Ocular allergies are caused by the same factors that cause hay fever. Common allergens include pet fur, dust mites, and tree pollen. The conjunctiva is the part of the eye that is most affected. When an allergen comes into contact with the eye, it causes blood vessels to dilate and expand, which increases the flow of inflammatory molecules.
