What causes red and swollen eyes?

Generally, eye redness and swelling are related to physiological causes, but they may also result from pathological conditions such as uveitis or keratitis. After onset, it is important to maintain good eye hygiene and follow medical advice when selecting treatment medications. Specific analyses are as follows:

I. Physiological Causes

Strong emotions or frequent eye rubbing can cause dilation of capillaries around the eyes and subcutaneous exudation, leading to swelling and congestion. In such cases, maintaining eye hygiene and avoiding frequent touching of the eyes are recommended. Cold compresses may be applied when necessary. Usually, no special treatment is required.

II. Pathological Causes

1. Uveitis

When bacteria or fungi enter the eye, they can infect the uveal tissue, causing intraocular inflammation and symptoms such as eye pain, redness, swelling, and stabbing discomfort. It is recommended to take medications such as dexamethasone acetate tablets, cyclosporine soft capsules, or prednisone acetate tablets under medical guidance. Appropriate medication use helps promote recovery.

2. Keratitis

Bacterial infection or prolonged wearing of contact lenses can damage the corneal tissue, resulting in symptoms such as photophobia, tearing, and swelling. In such cases, medications such as levofloxacin hydrochloride eye drops, tobramycin eye drops, or pranoprofen eye drops may be used according to medical advice. These drugs have antibacterial and bacteriostatic effects and help suppress inflammatory responses.

In addition to the above factors, orbital cellulitis could also be a possible cause. Immediate medical evaluation is recommended upon symptom onset, and good hygiene habits should be maintained in daily life.
