Allergic Conjunctivitis

In spring and summer, there is a type 1 hypersensitivity reaction to airborne allergens such as tree and grass pollen.

It often accompanies allergic rhinitis and asthma.

Eosinophils are seen in cytological examination of the conjunctiva.

Cold compress, steroid and cromaline sodium are used in its treatment.

The disease, which is more common in hot climates, increases its severity in spring and summer.

It is common between the ages of 5-20 and in males.

It is the second type of allergic conjunctivitis with the worst prognosis.

The cap shape is the most common. The view on the top lid is called the cobblestone view.

Horner-Trantas spots formed by degenerated cells are seen on them.

In the cornea, punctate epithelial erosions, shield-like ulcers and subepithelial scars can be seen.

It occurs between the ages of 30-50.

Coexistence of atopic dermatitis and asthma is common.

Scars are usually seen on the cornea and conjunctiva.

Shield-like corneal ulcers may be seen.

Symptoms are more severe, chronic and continuous than VKC.

For these reasons, allergic conjunctivitis has the worst prognosis.

It is especially seen in those who use intraocular foreign bodies (contact lenses, mechanical prostheses, etc.).

It is a type 1 hypersensitivity reaction.

It resolves completely with removal of the lens and steroid therapy.

It is allergic conjunctivitis with the best prognosis.

It is a delayed type hypersensitivity reaction that usually develops against tuberculoproteins.

Flickens (ropes) develop at the base of the limbus, which then ulcerate but heal without scarring.
