Ocular itching

Ocular itching, also known as ocular pruritus, is a hallmark symptom of ocular surface hypersensitivity and inflammatory disorders, most notably seasonal and perennial allergic conjunctivitis It affects the conjunctiva and ocular adnexa across both pediatric and adult populations exposed to environmental aeroallergens, irritants, or mechanical friction Histamine subsequently binds to H1 receptors on unmyelinated sensory nerve fibers in the conjunctiva, stimulating the transmission of the itch se...

It affects the conjunctiva and ocular adnexa across both pediatric and adult populations exposed to environmental aeroallergens, irritants, or mechanical friction Pathophysiologically, it is primarily driven by an immunoglobulin E (IgE)–mediated type I hypersensitivity reaction, wherein allergen binding triggers conjunctival mast cell degranulation and the subsequent release of histamine and other inflammatory mediators

Histamine subsequently binds to H1 receptors on unmyelinated sensory nerve fibers in the conjunctiva, stimulating the transmission of the itch sensation via the ophthalmic branch of the trigeminal nerve
