Abstract

Background: Allergic conjunctivitis is an immune-mediated disease primarily associated with type I hypersensitivity reactions. Objective: To analyze the clinical characteristics of patients with allergic conjunctivitis. Subjects and Methods: This study included 51 patients diagnosed and treated for allergic conjunctivitis at Hanoi Medical University Hospital from August 2023 to April 2024. Results: Itching was the most common symptom, reported in 88.2% of patients, followed by foreign body sensation (35.3%) and tearing (29.4%). Most patients maintained good visual acuity (≥20/30 in 98%), indicating minimal impact on visual function. Clinically, most cases presented with mild conjunctival hyperemia (grade I–II) and small papillae (<1 mm). Tear breakup time was mainly within 5–10 seconds, reflecting mild to moderate tear film instability. Conclusion: Itching is the most characteristic and frequent symptom of allergic conjunctivitis. The disease typically presents with mild conjunctival hyperemia, small papillae, and mild to moderate dry eye, while visual acuity is generally well preserved.
