Top 6 Causes of Conjunctivitis

The main causes of conjunctivitis are many and can be easily confused In addition,  conjunctivitis  can be caused by viruses, bacteria, allergens, and irritants. You can get viral and bacterial conjunctivitis when your eyes  come into contact with something contaminated with the virus or bacteria, for example your hands, tissues, etc. And through respiratory droplets. Sexual contact can lead to conjunctivitis through bacteria that cause chlamydia and gonorrhea.

Itching and red eyes  . Sound familiar? These symptoms point to an inflammation of the tissue that covers the eyes at the front called the conjunctiva. Conjunctivitis is a common problem and we all suffer from it at some point or another. But have you ever wondered what causes conjunctivitis?

Main Causes of Conjunctivitis:

  • Virus
  • Bacteria
  • fungi
  • allergic
  • foreign object in your eyes , smoke, dust;
  • eye conditions

A variety of factors can be responsible for conjunctivitis. So, check now  The 6 Main Causes of Conjunctivitis:

1. Virus: Viral conjunctivitis is extremely contagious. This infection is usually caused by adenoviruses, which cause colds, and sometimes enteroviruses, which also cause respiratory infections. Other disease-causing viruses such as mumps, measles, chickenpox, herpes, and rubella can also cause conjunctivitis.

Viral conjunctivitis is usually spread by contaminated hands touching the eye area . And how does this happen? Your hands can become contaminated by coming in contact with tears, respiratory debris, or fecal matter that has become infected. Being one of the  main causes of conjunctivitis.

You can also get viral conjunctivitis through respiratory droplets through coughing, sneezing. etc.; Or if the eyes  come into contact with a contaminated object, such as a towel or tissue. Also, the viruses that cause herpes can be passed from a mother to her baby during the birthing process and cause significant eye damage  in the child.

2. Bacteria: Bacterial conjunctivitis is also highly contagious. It is usually spread by contaminated hands touching the eyes . You can catch bacterial conjunctivitis by touching or using something an infected person has used and through respiratory droplets. Young children are especially vulnerable to this problem as they come into contact with other children infected with conjunctivitis at school or day care. Hygienic practices are also difficult to impose at this age. The bacteria that commonly cause this type of conjunctivitis in Brazil include Staphylococcus aureus, Streptococcus pneumoniae, Haemophilus influenza, and Moraxella catarrhalis. These are one of Main Causes of Conjunctivitis.

Some types of bacterial conjunctivitis need special attention: Neisseria gonorrhoeae, the bacteria that causes gonorrhea, can trigger a severe type of conjunctivitis that tends to develop suddenly. This type of conjunctivitis is spread through sexual contact when the eyes come into contact with the genital secretions of a person with gonorrhea. This infection can cause vision loss and requires immediate medical attention.

Chlamydia trachomatis: The bacteria that causes chlamydia can also lead to chronic conjunctivitis . They spread through sexual contact if they come into contact with genital secretions from an infected person. Chlamydia trachomatis also causes a type of conjunctivitis called trachoma, where scarring of the conjunctiva and cornea can be seen. It is the most common cause of infectious blindness. Trachoma can be spread by sharing contaminated items with an infected person, as well as through flies that sit in your eyes  after sitting in  an infected person’s eyes .

Both chlamydia and gonorrhea can cause conjunctivitis in a newborn if the infected mother transmits it during the birthing process. These infections can result in lasting eye damage in a baby and need immediate medical attention.

3. Fungi : Although it is rare to be one of the  Major Causes of Conjunctivitis , sometimes fungi can also cause conjunctivitis. These are usually seen in people who experience an eye injury that involves the eyes when they come in contact with organic matter such as dirt or plants. People who use corticosteroid eye drops for long periods of time can also get this infection.

4. Allergic Conjunctivitis: The body’s reaction to substances that are allergic can result in conjunctivitis. Allergic conjunctivitis is common in people who have other allergic conditions, such as asthma, eczema, and hay fever. This can be seasonal in nature if it is caused by things like pollen, weeds, grass, etc. It can be perennial if it’s caused by things like dander or pet mites that tend to be present throughout the year. Allergic conjunctivitis is one of the  main causes of conjunctivitis

5. Irritants: Substances that irritate your conjunctiva can also cause conjunctivitis. This can include a foreign object in your eyes , smoke, dust, wind, bright ultraviolet light, chlorine, etc. People who constantly have a foreign object like contact lenses in their eyes  can also develop conjunctivitis as a reaction to them.

6. Eye Conditions: Some eye conditions are also associated with conjunctivitis: Blepharitis, a condition where the eyelids become inflamed is also associated with conjunctivitis. Bacterial growth and scaly debris along the eyelid can also be seen during this condition. Chronic dacryocystitis, which is an infection, is also linked to conjunctivitis. This being one of the worst  main causes of conjunctivitis.

How to treat conjunctivitis:  The treatment of conjunctivitis will depend on its cause. Antibiotics may be prescribed for problems caused by bacteria, while viral cases may resolve on their own. In the meantime, avoid exposure to an allergen that can deal with the conjunctivitis caused by them. Seek medical attention if symptoms continue for more than 3 or 4 days or this problem affects your vision. It’s also a good idea to contact your doctor if your eyelids or the skin around your eyes  feels inflamed.
