Main Article Content
Abstract
The clinical manifestations of allergic conjunctivitis include: seasonal allergic conjunctivitis, perennial allergic conjunctivitis, spring conjunctivitis, atopic eczema conjunctivitis, giant papillary conjunctivitis. Seasonal conjunctivitis is most common and tends to progress to chronic, year-round conjunctivitis. A cross-sectional descriptive study on 62 subjects with a confirmed diagnosis of seasonal allergic conjunctivitis and perennial allergic conjunctivitis at Nghe An Eye Hospital in the year from April 1999 to August 2020 with the aim to describe the accompanying clinical and paraclinical characteristics. The results showed that the number of patients with seasonal allergic conjunctivitis was 49 (79%), 13 patients with perennial allergic conjunctivitis (21%). Of which 35 (56.5%) are men, 27 (43.5%) are women with the average age of 22.02 years. Patients were concentrated in the age group ≥19 (50%), followed by the age group 6-11 years old (33.9%). Clinical symptoms 100% of patients have pruritus, followed by tearing, conjunctival edema to varying degrees. Symptoms of photophobia and superficial epithelitis are uncommon, only mild or absent. There were 58 patients (93.5%) allergic to 2 or more types of allergens, house dust mites Df, Dp, Bt and American cockroaches were common allergens. There are 79% of patients with dry eyes in both eyes, with a short tear film break up time. The study has shown the common symptoms of seasonal and perennial allergic conjunctivitis, thereby contributing to the planning of an appropriate and effective treatment solution.
