If conjunctivitis goes untreated, the symptoms may worsen, leading to more serious complications. In some cases, the infection can spread to the cornea, causing corneal ulcers or even blindness. In addition, untreated conjunctivitis can also lead to scarring of the conjunctiva, which can cause a permanent loss of vision. Furthermore, bacteria and viruses that cause conjunctivitis can spread to other parts of the body, resulting in systemic infections. This is especially dangerous for people with weakened immune systems.
Untreated conjunctivitis can cause long-term discomfort and pain. Symptoms such as eye redness, sensitivity to light, itching, burning, and a gritty feeling may persist and become more severe. Additionally, untreated conjunctivitis may cause an increase in tear production, leading to excessive tearing and crusting around the eyes.
Finally, untreated conjunctivitis can lead to other eye problems. For instance, people with untreated conjunctivitis are at higher risk for developing glaucoma, cataracts, or other vision-related conditions.
It is important to seek treatment for conjunctivitis as soon as possible to avoid any of the potential serious complications. Treatment may involve antibiotics or antiviral medications, depending on the cause of the infection.
