Pink eye, also known as infectious conjunctivitis, is a common condition that often emerges in outbreaks during seasonal transitions or periods of hot, humid, and rainy weather. The disease spreads through direct contact with an infected person's eye secretions or by touching contaminated objects.

According to Doctor Nguyen Tra Thao Nhi, a Master of Science from the High-Tech Eye Center at Tam Anh General Hospital Ho Chi Minh City, many people consider pink eye benign and believe it will resolve on its own within 7 to 14 days, leading to delayed treatment. Some individuals only seek medical attention when the condition has worsened, with severe eye swelling, intense pain, and noticeable vision impairment. Consequences of delayed pink eye treatment can include the development of pseudomembranes, keratitis, and conjunctival scarring.

Doctor Nhi explained that certain pathogens causing conjunctivitis can lead to the formation of pseudomembranes or true membranes on the palpebral conjunctiva. These membranes can reduce treatment effectiveness and may cause scarring after recovery. In severe cases, this can result in entropion, where the eyelid turns inward, causing prolonged irritation and discomfort. If viruses or bacteria aggressively attack the eye, or if a patient rubs their eyes excessively, causing abrasions, the cornea (the clear front part of the eye) is vulnerable to damage. Without timely treatment, these lesions can leave permanent corneal scars, leading to blurred vision, glare, and even blindness if corneal perforation occurs.

When experiencing red eyes, some people habitually self-medicate with over-the-counter eye drops. Certain types contain corticosteroids, which can quickly alleviate redness. However, if used incorrectly, these drops can allow viruses to proliferate, increasing the risk of developing glaucoma and cataracts later on.

Doctor Nhi emphasized that not all red eye symptoms are benign. Serious conditions such as uveitis, severe keratitis, or an acute angle-closure glaucoma attack can begin with red eyes accompanied by pain, light sensitivity, and blurred vision. Therefore, delaying an eye examination can mean missing the critical "golden hour" for effective treatment.

Upon experiencing symptoms of pink eye, such as redness, irritation, and excessive discharge, patients should consult an ophthalmologist for a proper examination and suitable treatment. This will help minimize complications and reduce the risk of further spread.
