Japanese guidelines for allergic conjunctival diseases 2020

Area of Science:

• Ophthalmology
• Allergy and Immunology
• Clinical Management Guidelines

Background:

• Allergic conjunctival disease is a Type I allergic inflammatory condition of the conjunctiva.
• It presents with subjective symptoms like itching and objective signs such as conjunctival hyperemia.
• Specific forms include allergic conjunctivitis, atopic keratoconjunctivitis, vernal keratoconjunctivitis, and giant papillary conjunctivitis.

Purpose of the Study:

• To summarize the definition, classification, pathogenesis, diagnostic methods, clinical findings, and therapies for allergic conjunctival disease.
• To provide an overview based on the 2019 Guidelines for Clinical Management of Allergic Conjunctival Disease.

Main Methods:

• Review and synthesis of information from the 2019 Guidelines for Clinical Management of Allergic Conjunctival Disease.
• Focus on diagnostic criteria, clinical manifestations, and therapeutic strategies.

Main Results:

• Allergic conjunctival disease is characterized by Type I allergy, presenting with ocular itching, hyperemia, and conjunctival swelling.
• Vernal keratoconjunctivitis involves giant papillae and corneal lesions, causing foreign body sensation, pain, and photophobia.
• Diagnosis confirms Type I allergic reactions in the conjunctiva.

Conclusions:

• First-line treatment involves antiallergic eye drops, with steroid eye drops used for more severe cases.
• Immunosuppressive eye drops are adjunctively used for vernal keratoconjunctivitis treatment.
• Adherence to clinical management guidelines ensures appropriate diagnosis and therapy for allergic conjunctival diseases.
