1. Simple hyperemia of conjuctiva

2. Simple hyperaemia of conjunctiva means congestion of the conjunctival vessels due to acute exposure to some minor irritants without being associated with any of the established eye disease.

3. ETIOLOGY It may be acute and transient, or recurrent and chronic.

4. 1. Acute transient hyperaemia. It results due to temporary irritation caused by: i . Direct irritants such as a foreign body, misdirected cilia, concretions, dust, chemical fumes, smoke, stormy wind, bright light, extreme cold, extreme heat and simple rubbing of eyes with hands.

5. ii. Reflex hyperaemia due to eye strain, from inflammations of nasal cavity, lacrimal passages and lids.

6. iii. Hyperaemia associated with systemic febrile conditions. iv. Nonspecific inflammation of conjunctiva.

7. 2. Recurrent or chronic hyperaemia . It often occurs due to chronic exposure to irritant as in chronic smokers, chronic alcoholics, people residing in dusty, ill ventilated rooms, workers exposed to prolonged heat, in patients suffering from rosacea and insomnia or otherwise having less sleep.

8. Clinical features • Feeling of discomfort, heaviness, grittiness, tiredness and tightness in the eyes are common complaintsof patients with conjunctival hyperaemia . Mild lacrimation and minimal mucoid discharge, may occur.

9. On cursory examination, the conjunctiva often looks normal. However, eversion of the lids may reveal mild to moderate congestion being more marked in fornices .

10. Treatment Removal of the cause of hyperaemia , e.g. in acute transient hyperaemia the removal of irritants (e.g. misdirected cilia) gives prompt relief.

11. Symptomatic relief may be achieved by topical decongestants (e.g. 1:10000 adrenaline drops) or naphazoline drops.
