Bacterial Conjunctivitis. Bacterial conjunctivitis is caused by infection of the eye with certain bacteria. Bacterial conjunctivitis. 1  Usually begins in one eye and may sometimes progress to the second eye. 2  Is a leading cause of children being absent from day care or school (Patel, 2007). The most common causes of conjunctivitis are viruses, bacteria, and allergens. But there are other causes, including chemicals, fungi, certain diseases, and contact lens wear (especially wearing lenses overnight). Eye Infections are eye ailments caused by bacterial, viral, or fungal agents. There are many different types of eye infections, with different causes and treatments. People who wear contact lenses are particularly susceptible to eye infections due to the decrease in oxygen reaching their corneas and due to bacterial or fungal buildup caused by failure to properly disinfect their contact lenses. Some common eye infections are pink eye, blepharitis, and trachoma. Bacterial conjunctivitis is a common type of pink eye, caused by bacteria that infect the eye through various sources of contamination. The bacteria can be spread through contact with an infected individual, exposure to contaminated surfaces or through other means such as sinus or ear infections. The most common types of bacteria that cause bacterial conjunctivitis include Staphylococcus aureus, Haemophilus influenzae, Streptococcus pneumoniae and Pseudomonas aeruginosa. Bacterial conjunctivitis usually produces a thick eye discharge or pus and can affect one or both eyes. Causes and Types of Eye Infections. Examples of viral, fungal and bacterial eye infections include: 1  Pink eye, or conjunctivitis. 2  Conjunctivitis, also called pink eye, is a common, highly contagious eye infection that often is spread among children in day care centers, classrooms and similar environments. There are many different types of eye infections, and your eye doctor needs to determine the particular type of eye infection you have in order to prescribe the proper treatment. Your doctor may take a sample from the affected area of your eye for a culture to assess the exact type of infection you have, if any. Eye infections can affect any part of the eyes, from the eyelids to the cornea, and even the retina in the back of the eye. Eye infections are so common that most of us either have had an eye infection or know someone who has had one. Eye infections can be bacterial, viral, or fungal. People who wear contact lenses are particularly susceptible to eye infections due to the decrease in oxygen reaching their corneas and due to bacterial or fungal buildup caused by failure to properly disinfect their contact lenses. Some common eye infections are pink eye, blepharitis, and trachoma. Conjunctivitis when caused by an infection is most commonly caused by a viral infection. Bacterial infections, allergies, other irritants and dryness are also common causes. Both bacterial and viral infections are contagious and passed from person to person, but can also spread through contaminated objects or water. It is commonly due to an infection (usually viral, but sometimes bacterial or parasitic), or an allergic reaction. Conjunctivitis can affect one or both eyes and is the most likely diagnosis in someone with eye redness and discharge (fluid coming from the eye). Pinterest0. Google+0. Twitter0. The eye infections are caused by various reasons such as viral or bacterial attack and the effects can range from simple discomfort to severe pain and swelling that may have serious consequences unless treated urgently by qualified eye specialists. Blepharitis eye infections are of two basic types – Anterior Blapharitis and Posterior Blapharitis depending on which portion of the eye the infection actually affects. The primary cause for this kind of eye infections is bacterial action and presence of dandruff on the eyebrows. (May 2012). Conjunctivitis, also known as pink eye is inflammation of the conjunctiva (the outermost layer of the eye and the inner surface of the eyelids). It is commonly due to an infection (usually viral, but sometimes bacterial or parasitic), or an allergic reaction. Conjunctivitis can affect one or both eyes and is the most likely diagnosis in someone with eye redness and discharge (fluid coming from the eye). Background. Inflammation of the bulbar and/or palpebral conjunctiva, or conjunctivitis, can be caused by allergies, viruses, or bacteria. Bacterial conjunctivitis is commonly caused by staphylococci, streptococci, chlamydial organism, and gonococci. Common causes of bacterial conjunctivitis, an inflammation of the bulbar and/or palpebral conjunctivas, include staphylococci, streptococci, gonococci, and Chlamydia. Complications are expected to develop only in cases caused by extremely pathogenic bacteria, such as C trachomatis or Neisseria gonorrhoeae. Fungal Eye Infections. Fungal eye infections are extremely rare, but they can be very serious. The most common way for someone to develop a fungal eye infection is as a result of an eye injury, particularly if the injury was caused by plant material such as a stick or a thorn.
