	*Conjunctiva has less innervation than cornea so patients are far less symptomatic		*Superficial disruption of the conjunctival epithelium from trauma, foreign body, or chemical exposure
			*Conjunctiva has less innervation than cornea → patients are far less symptomatic than with [[corneal abrasion]]
			*Heals rapidly (typically within 24-48 hours)

	==Clinical Features==		==Clinical Features==
	*Foreign body sensation		*Foreign body sensation
	*Mild [[eye pain\|pain]]		*Mild [[eye pain\|pain]] or irritation
			*Tearing, mild redness
	*Photophobia (rare)		*Photophobia (rare)
	*[[Subconjunctival hemorrhage]] ~~(rare)~~		*[[Subconjunctival hemorrhage]] may be present

	==Differential Diagnosis==		==Differential Diagnosis==
			*[[Corneal abrasion]]
			*[[Conjunctival laceration]]
			*[[Subconjunctival hemorrhage]]
			*[[Conjunctivitis]]
			*[[Open globe injury]] (must rule out with high-energy mechanism)

	==Evaluation==		==Evaluation==
	*[[Slit-lamp]] exam with fluorescein		*Visual acuity
	**Seidel test to ~~role-~~out globe perforation		*[[Slit-lamp]] exam with fluorescein staining — conjunctival uptake without corneal involvement
			*'''Seidel test''' to rule out globe perforation (especially if mechanism of concern)
			*Evert eyelids to look for retained [[ocular foreign body\|foreign body]]

	==Management==		==Management==
	*Remove ~~[[ocular foreign body\|~~conjunctival foreign bodies]]		*Remove any conjunctival foreign bodies
	*[[Erythromycin]] ointment 0.5% QID x2-3d		*[[Erythromycin]] ointment 0.5% QID × 2-3 days (prophylaxis)
	*~~Suture of lacerations~~ is almost never required		*Artificial tears PRN for comfort
			*Suturing is almost never required (conjunctiva heals rapidly)
			*No eye patching needed

			==Disposition==
			*Discharge with erythromycin ointment
			*Follow-up only if worsening symptoms; most heal within 24-48 hours
