Conjunctivitis:
Causes and incidence
(Professional Guide to Diseases (Eighth Edition))
The most common causative organisms include:
❑ bacterial — Staphylococcus aureus, Streptococcus pneumoniae, Neisseria gonorrhoeae, Neisseria meningitidis
❑ chlamydial — Chlamydia trachomatis (inclusion conjunctivitis)
❑ viral — adenovirus types 3, 7, and 8; herpes simplex virus, type 1.
Other causes include allergic reactions to pollen, grass, topical medications, air pollutants, smoke, or unknown seasonal allergens (vernal conjunctivitis); environmental (wind, dust, and smoke) and occupational irritants (acids and alkalies); and a hypersensitivity to contact lenses or solutions.
Vernal conjunctivitis (so-called because symptoms tend to be worse in the spring) is a severe form of immunoglobulin E-mediated mast cell hypersensitivity reaction. This form of conjunctivitis is bilateral. It usually begins at age 3 to 5 years and persists for about 10 years. It’s sometimes associated with other signs of allergy commonly related to pollens, asthma, and allergic rhinitis.
Epidemic keratoconjunctivitis is an acute, highly contagious viral conjunctivitis caused by adenovirus types 8 and 19. It’s commonly complicated by visual loss due to corneal subepithelial infiltrates. Health care providers must be careful to wash their hands and sterilize equipment to prevent the spread of this disease.
In the Western hemisphere, conjunctivitis is probably the most common eye disorder.

Inclusion conjunctivitis:
Causes and incidence
(Professional Guide to Diseases (Eighth Edition))
C. trachomatis is an obligate intracellular organism of the lymphogranuloma venereum serotype group. Serotypes D through K are sexually transmitted, and secondary eye involvement in adults occurs in about 1 in 300 genital cases. Because contaminated cervical secretions infect the eyes of the neonate during birth, inclusion conjunctivitis is an important cause of ophthalmia neonatorum. Ocular chlamydial disease occurs most frequently in adults between ages 18 and 30.

About prevalence and incidence statistics:
The term 'prevalence' of Conjunctival disorders usually refers to the estimated population
of people who are managing Conjunctival disorders at any given time.
The term 'incidence' of Conjunctival disorders refers to the annual diagnosis rate,
or the number of new cases of Conjunctival disorders diagnosed each year.
Hence, these two statistics types can differ:
a short-lived disease like flu can have high annual incidence but low prevalence,
but a life-long disease like diabetes has a low annual incidence but high prevalence.
