Introduction
Causes of Conjunctival Hyperemia (Eye Redness):
1. For cases caused by bacterial infection, topical antibiotic eye drops may be used. However, they must not be abused in non-infectious cases and should never be routinely prescribed as a placebo.
2. Topical corticosteroid eye drops may be trialed cautiously; however, prolonged use is contraindicated, and intraocular pressure must be closely monitored.
3. Etiology-directed treatment should be implemented.
Many people experience conjunctival or ocular hyperemia (redness of the eye) in daily life. There are numerous potential causes, including bacterial or viral infection of the eye, entry of foreign particles (e.g., dust) into the eye, eye strain from prolonged visual tasks, allergic reactions, or external irritants. Regardless of the underlying cause, individuals experiencing ocular redness should promptly seek medical evaluation at a hospital and undergo appropriate treatment under professional ophthalmologic guidance.
Treatment of Ocular Hyperemia
1. For cases attributable to bacterial infection, topical antibiotic eye drops may be prescribed, typically administered three to four times daily. Antibiotics should not be used indiscriminately for non-infectious causes, nor should they be routinely prescribed as placebo therapy.
2. Topical corticosteroid eye drops may be considered in select cases; however, their use should be limited in duration, and intraocular pressure must be closely monitored during treatment.
3. Etiology-directed therapy—treatment targeting the specific underlying cause—is essential.
4. While traditional Chinese herbal decoctions may be difficult to adhere to long-term, patients may opt for evidence-informed, syndrome-differentiated herbal teas such as Chrysanthemum-Lycium tea (Ju Qi Cha), formulated according to TCM principles.
5. Modern lifestyle-related hyperemia—for example, excessive screen time (computers, smartphones) leading to eye redness.
6. Trauma-induced ocular hyperemia;
7. Postoperative ocular hyperemia;
8. Inflammatory hyperemia—including conjunctivitis, keratitis, and other inflammatory conditions affecting the ocular surface or intraocular structures.
Causes of Ocular Hyperemia
1. Inflammation-induced ocular hyperemia
(1) Infectious causes
Including bacterial, viral, fungal, or parasitic infections. These may lead to conditions such as keratitis, corneal ulcers, uveitis, purulent iridocyclitis, endophthalmitis, panophthalmitis, orbital cellulitis, and various forms of conjunctivitis.
(2) Allergic (hypersensitivity) causes
Such as allergic reactions to exogenous antigens (e.g., medications), autoantigens, or autoimmune disorders. Common examples include drug-induced allergy, phlyctenular keratoconjunctivitis, vernal keratoconjunctivitis, interstitial keratitis, scleritis, and iridocyclitis.
2. Trauma-induced ocular hyperemia
Includes all types of ocular trauma—such as blunt impact, contusion, collision, falls, surgical procedures—as well as presence of intraocular foreign bodies.
3. Pressure-induced ocular hyperemia
Refers to hyperemia resulting from sudden elevation of intraocular or orbital pressure, causing circulatory impairment and localized congestion. Seen in acute angle-closure glaucoma, orbital space-occupying lesions, and similar conditions.
The above outlines key aspects of diagnosis and management of ocular hyperemia. In daily life, individuals should prioritize ocular hygiene and protection: avoid excessive visual strain, take regular breaks when eyes feel fatigued, and maintain a balanced diet rich in nutrients beneficial for eye health.
