Pink eye indicates some form of ocular inflammation. This condition is typically benign and self-limiting. Recognizing red flags that warrant urgent referral to an ophthalmologist is crucial for preventing long-term complications. Referral is essential when patients experience severe eye pain, copious purulent discharge, vision loss, distorted pupils, severe photophobia, ocular trauma, or herpes infection.The cause of red eye can be diagnosed through a detailed medical history and thorough eye examination.

Treatment options for pink eye in certain situations :
1. Viral Conjunctivitis : Treatment is supportive and may include cold compresses and artificial tears. Topical antibiotics are rarely used, as secondary bacterial infections are uncommon. One study indicates SARS-CoV-2 can be transmitted via droplets, but infected patients are unlikely to spread the virus through tears.Researchers at Singapore's National Centre for Infectious Diseases collected tear samples from 17 COVID-19 patients from the onset of symptoms until recovery, typically on day 20.None of the patients presented with ocular symptoms, though one developed conjunctival swelling during hospitalization. The virus was not detected in any of the 64 tear samples collected during the study period; however, viral load was detected in nasal and throat swabs.
2. Bacterial conjunctivitis : Antibiotics form the mainstay of treatment, with selection based on cost-effectiveness and local bacterial resistance patterns.
3. Chlamydial conjunctivitis : Treatment includes topical erythromycin eye ointment, along with oral therapy using azithromycin (single 1-gram dose) or doxycycline (100 mg twice daily for 14 days) to clear genital infection. Sexual partners must be identified and treated.
4. Allergic Conjunctivitis : Avoiding allergen exposure and using artificial tears are effective methods for relieving symptoms in mild cases. Over-the-counter antihistamines/vasoconstrictors are also viable options, while topical steroids may be required to treat acute flare-ups.
5. Dry Eye Syndrome: Treatment involves frequent application of artificial tears and ointments throughout the day and night to reduce evaporation rates. Newer therapies include topical environmental spore-containing eye drops, which increase tear production. Omega-3 fatty acids have also been shown to be beneficial.
6. Scleritis: Topical NSAIDs have not demonstrated significant benefit over placebo in treating scleritis. Topical steroids may be useful for severe cases, though the condition is typically self-limiting.
7. Subconjunctival hemorrhage: Warm compresses and ophthalmic lubricants are sufficient. Recurrent bleeding may require a physical examination.
