Conjunctivitis is a type of localized inflammation, similar to other inflammations. This disease may recur frequently, especially in children, infants, elderly or frail patients, or those with chronic debilitating diseases such as diabetes. Due to weaker bodily resistance, these individuals are more susceptible to repeated bacterial infections. To avoid such situations, it is advised to pay attention to healthy dietary habits, avoid spicy and irritating foods, and appropriately increase physical exercise to enhance resistance, thereby minimizing the chances of disease recurrence.

Conjunctivitis symptoms

Conjunctivitis is an inflammation that occurs in the thin layer of structure on the surface of the white eyeball and the inner surface of the eyelid. Conjunctivitis can be caused by infections such as bacteria, viruses, chlamydia, fungi, parasites, etc., and by environmental factors like sand, smoke, ultraviolet exposure, and chemical injuries from acids, alkalis, or toxic gases. It can also be an inflammatory response of the conjunctiva due to allergic or systemic diseases including tuberculosis, syphilis, thyroid disorders, or surrounding tissues of the eye such as the cornea, sclera, eyelids, nasal cavity, and sinuses. Common symptoms of conjunctivitis include red eyes, a sensation of a foreign body in the eye, burning, itching, photophobia (sensitivity to light), tearing, and increased discharge. Sometimes it can also cause eye pain.

Acute conjunctivitis etiology

Acute conjunctivitis, also known as acute catarrhal conjunctivitis and commonly referred to as pink eye, is highly contagious. It is most often seen in the spring and autumn seasons. The infection can occur sporadically or can spread in community settings such as schools and factories. The onset of the disease is sudden, with an incubation period of one to three days. Both eyes may be affected simultaneously or one to two days apart. The inflammation is most severe three to four days after onset and then gradually lessens, with the course of the disease generally lasting less than three weeks. The most common pathogens are Streptococcus pneumoniae, Staphylococcus aureus, and Haemophilus influenzae. The pathogens can vary with the seasons; studies indicate that infections in the winter are mainly caused by Streptococcus pneumoniae, while Haemophilus influenzae conjunctivitis is more common in the spring and summer.
