A pink eye is the most obvious symptom of conjunctivitis, so on this website “pink eye” refers to for this common eye problem.
“Pinkeye” or Conjunctivitis, is inflammation of the conjunctiva, the mucous membrane that lines the inside of the eyelids of vertebrates and that extends to the front of the eyeball.
“Pink Eye” is most commonly expressed by redness, photophobia and tearing (sign can also be infectious crusts in the morning, enlarged lymph nodes, allergic itching, etc.). Conjunctivitis usually lasts between 1 and 3 weeks.
A pink eye, itching, irritation, pain, grittiness, crusting or light sensitivity, are symptoms that can give you an idea about the type of conjunctivitis you could have.
According to its etiology, conjuctivitis can be classified as these types:
1) Bacterial Conjunctivitis, characterized by abundant, yellowish secretion and formation of papillae in the palpebral conjunctiva. It is treated with ocular hygiene and topical antibiotics. Staphylococci and Streptococci, among others, are types of bacteria that often cause Bacterial pink eye.
2) Viral Conjunctivitis, is not the most common and is usually caused by adenovirus. It is often less gummy and possible a more painful corneal disease. This form of “Pink Eye” is very contagious and is usually resolved spontaneously, although systematic topical treatment and frequent washing can help.
3) Allergic Conjunctivis: typically seasonal, not known for having a major itch, but to have gummy mucus and is frequently associated with sinusitis.
4) Pink eye caused by foreign body in the eye, or eye trauma
One cause of conjunctivitis is a bacterial infection. Different bacteria may be responsible for the infection. In bacterial conjunctivitis, pink eye symptoms are usually associated with watery green or yellow discharge. Often symptoms, such as sinus congestion and runny nose are present. The eyelids are swollen.
Although bacterial conjunctivitis often does not require antibiotics, those affected should see a doctor, because this form of conjunctivitis is often associated with an infection of the cornea.
Another reason could be the misuse of contact lenses or contact lenses. If your eye comes in contact with microbes and the lens is not properly disinfected, it will be transferred to the eye using the lens and can cause slight conjunctivitis.
This infection must be correctly diagnosed and treated. Bacterial conjunctivitis is very contagious but usually heal within 7 to 10 days after onset of symptoms.
