Introduction

Allergic conjunctivitis may or may not affect vision. It mainly presents with symptoms such as itchy eyes, redness, and a burning sensation. Symptoms typically resolve with medications like loratadine tablets or cetirizine hydrochloride tablets, and vision remains unaffected. However, if the condition progresses and adversely affects the cornea, leading to keratitis or conjunctivitis, it may result in decreased vision.

Allergic conjunctivitis may or may not affect vision, depending on the severity of the disease.

1. Vision may remain unaffected

Allergic conjunctivitis is primarily an allergic reaction of the eye triggered by irritants such as pollen, dust mites, and catkins. It mainly manifests as symptoms including itchy eyes, redness, burning sensation, foreign body sensation, increased eye discharge, and tearing. Typically, under a doctor's guidance, treatment with antihistamines such as loratadine tablets or cetirizine hydrochloride tablets gradually relieves symptoms without affecting vision.

2. Vision may be affected

In more severe cases, transient blurred vision may occur, but this usually resolves gradually with treatment and does not permanently impair vision. However, if the condition persists and progresses, it may adversely affect the cornea, leading to conditions such as keratitis or conjunctivitis. In serious cases, significant vision loss or optic nerve damage may result.

What are the symptoms of allergic conjunctivitis?

Allergic conjunctivitis may cause symptoms such as itchy eyes, conjunctival congestion, and blurred vision. When the patient's eye is stimulated by an allergen, a localized hypersensitivity immune reaction tends to develop. The skin in this area is relatively thin, making it susceptible to itching, redness, and swelling under the influence of this immune response.
