Introduction
In general, the treatment of infectious conjunctivitis mainly includes routine care, antibiotic therapy, antiviral therapy, symptomatic relief, and isolation precautions. In addition, patients should follow medical advice for proper medication use and must not adjust the dosage or change medications on their own. If symptoms do not improve after 3–5 days of treatment, or if there is decreased vision, worsening eye pain, or other such conditions,
In general, the treatment of infectious conjunctivitis mainly includes basic care, antibiotic therapy, antiviral therapy, symptomatic relief, and isolation precautions. The details are as follows:
1. General Care
Maintaining ocular hygiene is fundamental. Patients can gently wipe eye secretions with sterile saline solution to prevent accumulation that may worsen infection. They should avoid rubbing their eyes to prevent spreading pathogens or damaging the ocular surface. Adequate rest, reduced screen time, protection from bright light, and ensuring good indoor air circulation help create a comfortable environment and promote full recovery of the eyes.
2. Antibiotic Therapy
This approach is suitable for bacterial infections. Under medical guidance, patients may use levofloxacin eye drops, tobramycin eye drops, chloramphenicol eye drops, erythromycin eye ointment, or moxifloxacin eye drops. These medications work by inhibiting bacterial growth or destroying bacterial structures, effectively targeting common pathogens such as Staphylococcus and Streptococcus species, rapidly controlling infection and relieving symptoms.
3. Antiviral Therapy
For viral infections such as those caused by adenovirus or herpesvirus, patients may use acyclovir eye drops, ganciclovir ophthalmic gel, or ribavirin eye drops under medical supervision. These drugs inhibit viral DNA or RNA replication, preventing further spread of the virus, shortening the duration of illness, and reducing the risk of complications. Early initiation of treatment upon symptom onset is crucial for optimal effectiveness.
4. Symptomatic Relief
To address symptoms such as redness, swelling, and itching, patients may use sodium cromoglicate eye drops (to alleviate allergy-like discomfort) or pranoprofen eye drops (to reduce inflammatory responses) as directed by a physician. If thick discharge causes eyelid adhesion, applying an ophthalmic gel before bedtime can provide moisture and prevent sticking, improving comfort and supporting recovery.
5. Isolation and Protection
Infectious conjunctivitis is contagious. Patients should use separate personal items such as towels and washbasins and avoid sharing them with others. Used items should be disinfected promptly, either by boiling or soaking in chlorine-based disinfectants. Patients should minimize outings and avoid crowded places during treatment to prevent transmission to others, continuing these precautions until all symptoms have completely resolved.
In addition, patients must follow medical instructions strictly when using medications and should not adjust dosages or switch drugs on their own. If symptoms do not improve after 3–5 days of treatment, or if there is vision decline or worsening eye pain, they should seek immediate medical attention for treatment adjustment. Children and elderly patients have unique physiological characteristics and require specially selected safe medications under doctor’s supervision to ensure safe and effective treatment.
