The ear

• The ear is compose of the inner an outer ear.

• Ear rugs: Otic drugs(external ear)

• drugs of the inner ear: cerumenolytic

• for adult pull ear back and up

• for child, pull back and down

Opthalmic

• ophthalmic drugs: drugs applied to the eye

• The eye excretes through glands: (lacrimal gland; tear gland, lacrimal sac; tear sac,

• Aqueous humor: synovial fluid of the eyes, produces by the ciliary body,equates with Intraocular pressure

• Eye constriction: myiosis

• Eye dilation: mydriasis

• normal IOP: 10-20 mm/HG

Glaucoma

• chronic eye disease associated with IOP that closes the optic nerve

• if untreated , causes loss of peripheral vision

• Recommended drugs: Prostaglandin analogues, beta-adrenergic agents, alpha adrenergic agents, cholinergic drugs, Carbonic anhydrase inhibitors
