1.	What is correct about pathophysiology of giant papillary conjunctivitis (GPC)?
	d -- may be related with atopic disease
2.	What is the most likely diagnosis?
	c -- atopic conjunctivitis
3.	What is correct for the treatment?
	a -- topical steroid is more effective than topical antihistamine in an acute stage

Atopic conjunctivitis is also associated with other ocular findings including keratoconus, subcapsular cataracts, and corneal vascularization. Histologically, one may see mast cell infiltration of the conjunctival epithelium.  The patients may be treated with topical allergy medications and systemic antihistamines.  Topical steroids can be used during acute exacerbations of the disease but chronic use should be avoided as cataracts and elevated IOP are potential side effects.
