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]
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.
Generally, conjunctivitis does not affect the pupils. With acute angle-closure glaucoma , the pupil is generally fixed in mid-position, oval, and responds sluggishly to light, if at all. Shallow anterior chamber depth may indicate a predisposition to one form of glaucoma (narrow angle) but requires slit-lamp examination or other special ...
The development and pathophysiology of SLK is not well understood, but appears to involve microtrauma of keratoconjunctival surfaces. [6] This mechanical hypothesis is supported by the increased lid apposition of exophthalmic thyroid patients, who are known to have an increased incidence of superior limbic keratoconjunctivitis.
[2] [3] [4] Chronic conjunctivitis such as from tobacco smoke exposure or infection may also lead to the condition. [2] Diagnosis is mostly based on the symptoms, though a number of other tests may be used. [8] Dry eye syndrome occasionally makes wearing contact lenses impossible. [2] Treatment depends on the underlying cause.
Allergic conjunctivitis is a frequent condition as it is estimated to affect 20 percent of the population on an annual basis and approximately one-half of these people have a personal or family history of atopy. [citation needed] Giant papillary conjunctivitis accounts for 0.5–1.0% of eye disease in most countries. [citation needed]
In ophthalmology, mucopurulent discharge from the eyes, and caught in the eyelashes, is a hallmark sign of bacterial conjunctivitis. The normal buildup of tears, mucus, and dirt (compare rheum) that appears at the edge of the eyelids after sleep is not mucopurulent discharge, as it does not contain pus. Vaginal discharge
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 ...
