Conjunctivitis is the most common eye disease. [45] Rates of disease is related to the underlying cause which varies by the age as well as the time of year. Acute conjunctivitis is most frequently found in infants, school-age children and the elderly. [18] The most common cause of infectious conjunctivitis is viral conjunctivitis. [26]
Acute hemorrhagic conjunctivitis (AHC) (also spelled acute haemorrhagic conjunctivitis) is a derivative of the highly contagious conjunctivitis virus, [1] otherwise known as pink eye. Symptoms include excessively red, swollen eyes as well as subconjunctival hemorrhaging. Currently, there is no known treatment and patients are required to merely ...
Adenoviral keratoconjunctivitis, also known as epidemic keratoconjunctivitis, is a contagious eye infection, a type of adenovirus disease caused by adenoviruses. [1] It typically presents as a conjunctivitis with a sudden onset of a painful red eye, watery discharge and feeling that something is in the eye. [3]
Keratoconjunctivitis is frequently caused by viral infections in and around the eyes. A particularly common cause of this is the herpes simplex virus.In some people, the infection may become chronic and keratoconjunctivitis may present during flare-ups of variable frequency.
[2] 75% of conjunctivitis cases are due to adenovirus infection. [13] In 2016, the Global Burden of Disease Study estimated that globally, around 75 million episodes of diarrhea among children under the age of five-years, were attributable to adenovirus infection. [12] The first adenoviral strains were isolated in 1953 by Rowe et al. [14]
Recurrence can be accompanied by chronic dry eye, low grade intermittent conjunctivitis, or chronic unexplained sinusitis. Following persistent infection the concentration of viral DNA reaches a critical limit. Antibody responses against the viral antigen expression in the stroma can trigger a massive immune response in the eye.
Vernal keratoconjunctivitis (VKC, also Spring catarrh, Vernal catarrh or Warm weather conjunctivitis) is a recurrent, bilateral, and self-limiting type of conjunctivitis (pink eye) having a periodic seasonal incidence.
An ocular manifestation of a systemic disease is an eye condition that directly or indirectly results from a disease process in another part of the body. There are many diseases known to cause ocular or visual changes.
