Overview

Overview

Allergic conjunctivitis can be attributed to a variety of causative agents, both natural and artificial.

Causes

Causes

Transitory allergens:

  • Tree pollen
  • Grass pollen

Indoor allergens

  • House dust mites
  • Animal dander
  • Mold spores
  • Cockroach
  • Rodents

The smaller allergens, being more easily volatile, are more potent.

There is usually a history of asthma, systemic atopic disease or eczema. It is perennial in nature with worsening in the winter months.

The incidence peaks during spring when exposure to tree grass pollens increases[3].

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].

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].
