What causes soreness and swelling in the right eye?

Right eye soreness and swelling may be caused by eye strain, dry eye syndrome, keratitis, glaucoma, iridocyclitis, or other reasons. Treatment should be based on the specific condition. Detailed analysis is as follows:

1. Eye Strain

Excessive watching of television or computer screens, or prolonged熬夜 (staying up late), can lead to eye fatigue, resulting in symptoms such as dryness, soreness, and aching eyes. Under medical guidance, eye drops that relieve eye fatigue may be used for improvement. Commonly used medications include sodium hyaluronate eye drops, escin and digitalis glycosides eye drops, and polyvinyl alcohol eye drops.

2. Dry Eye Syndrome

Insufficient tear production, excessive tear evaporation, or abnormal tear composition can also cause eye soreness, dryness, or visual disturbances. Under medical supervision, patients may use medications that promote tear secretion. Commonly used drugs include prednisolone acetate eye drops, polyvinyl alcohol eye drops, and carboxymethylcellulose sodium eye drops.

3. Keratitis

After the cornea is infected by pathogens, corneal tissue may become congested and swollen, leading to symptoms such as eye soreness, sharp pain, and a burning sensation. It is recommended to follow medical advice and use topical antibiotics such as levofloxacin hydrochloride eye drops, tobramycin eye drops, or gatifloxacin eye drops to control inflammation and alleviate symptoms.

4. Glaucoma

This condition may damage the optic nerve and is often associated with chronically elevated intraocular pressure, which can easily cause symptoms such as eye aching, redness, swelling, and pain. Under medical guidance, topical medications such as timolol maleate eye drops, carteolol hydrochloride eye drops, or pilocarpine nitrate eye drops may be used to help lower intraocular pressure and relieve symptoms.

5. Iridocyclitis

When inflammation occurs in the iris tissue, it may interfere with normal iris function, causing the pupil to lose its ability to dilate or constrict properly, leading to increased intraocular pressure. This results in blurred vision, eye soreness, and a sensation of eye swelling. Under medical guidance, medications such as atropine sulfate eye drops, pranoprofen eye drops, or diclofenac sodium eye drops may be used to improve symptoms.

Proper eye care is essential for right eye soreness. Avoid prolonged use of electronic devices. If eye soreness persists for an extended period, it is advisable to seek timely medical evaluation at a hospital to identify the underlying cause and receive appropriate treatment.
