What's wrong with having a blister-like swelling on the white part of the eye?

The white part of the eye has developed a swollen, blister-like condition, which may be caused by conditions such as bacterial conjunctivitis, allergic conjunctivitis, or diabetic neuropathy.

1. Bacterial Conjunctivitis

The white area of the eye belongs to the bulbar conjunctiva. When infected with susceptible bacteria, it can lead to tissue edema, presenting as a blister-like swelling. Under medical guidance, patients may use targeted antibacterial treatments such as tobramycin eye drops, lomefloxacin hydrochloride eye drops, or gatifloxacin eye drops to prevent further progression of the condition.

2. Allergic Conjunctivitis

The bulbar conjunctiva is part of the conjunctiva. Upon exposure to allergens, it may trigger a localized non-specific immune response, leading to symptoms such as conjunctival blisters, eye pain, and involuntary tearing. Patients should follow medical advice and use systemic and local anti-allergy treatments, such as tripelennamine hydrochloride capsules, diclofenac sodium eye drops, or ketotifen fumarate eye drops.

3. Diabetic Neuropathy

If diabetes is not promptly controlled and treated, it can cause damage to ocular blood vessels, glands, nerves, and other tissues. Due to local fluid retention, glandular secretions within the eye may accumulate and form blister-like elevations in the conjunctival area. Under medical supervision, patients should use long-term glucose-lowering therapies such as insulin glargine injection, glimepiride tablets, or metformin hydrochloride tablets to slow disease progression.

Other conditions, such as optic nerve tumors, may also produce similar symptoms. It is recommended that patients seek standardized evaluation at a hospital to accurately identify the underlying cause.
