Overview
Allergic conjunctivitis can be attributed to a variety of causative agents, both natural and artificial.
Causes
Seasonal allergic conjunctivitis[1]
Transitory allergens:
- Tree pollen
- Grass pollen
Perennial allergic conjunctivitis[1]
Indoor allergens
The smaller allergens, being more easily volatile, are more potent.
Atopic keratoconjunctivitis[2]
There is usually a history of asthma, systemic atopic disease or eczema. It is perennial in nature with worsening in the winter months.
Vernal keratoconjunctivitis
The incidence peaks during spring when exposure to tree grass pollens increases[3].
Giant papillary conjunctivitis
It is predominantly iatrogenic, triggered by foreign bodies in the eye such as contact lenses, prostheses, or protruding corneal sutures, all of which may precipitate and perpetuate an inflammatory response[4].
Contact hypersensitivity
This is usually precipitated by exposure to an iatrogenic allergen, such as eye cosmetics or ocular therapeutic preparations, whose withdrawal leads to clinical improvement[5].
