Glaucoma is a disease of the major nerve of vision, called the optic nerve. The optic nerve receives light-generated nerve impulses from the retina and transmits these to the brain, where we recognize those electrical signals as vision. Glaucoma is characterized by a particular pattern of progressive damage to the optic nerve that generally begins with a subtle loss of side vision (peripheral vision). If glaucoma is not diagnosed and treated, it can progress to loss of central vision and blindness.
Glaucoma is usually, but not always, associated with elevated pressure in the eye (intraocular pressure). Generally, it is this elevated eye pressure that leads to damage of the eye (optic) nerve. In some cases, glaucoma may occur in the presence of normal eye pressure. This form of glaucoma is believed to be caused by poor regulation of blood flow to the optic nerve.

The following adverse reactions have been reported in clinical trials with Carteolol Hydrochloride (carteolol) Ophthalmic Solution.
Transient eye irritation, burning, tearing, conjunctival hyperemia and edema occurred in about 1 of 4 patients. Ocular symptoms including blurred and cloudy vision, photophobia, decreased night vision, and ptosis and ocular signs including blepharoconjunctivitis, abnormal corneal staining, and corneal sensitivity occurred occasionally.
As is characteristic of nonselective adrenergic blocking agents, Carteolol may cause bradycardia and decreased blood pressure (See WARNINGS). The following systemic events have occasionally been reported with the use of Carteolol Hydrochloride (carteolol) Ophthalmic Solution: cardiac arrhythmia, heart palpitation, dyspnea, asthenia, headache, dizziness, insomnia, sinusitis, and taste perversion. The following additional adverse reactions have been reported with ophthalmic use of beta1 and beta2 (nonselective) adrenergic receptor blocking agents:
Headache
Arrhythmia, syncope, heart block, cerebral vascular accident, cerebral ischemia, congestive heart failure, palpitation (see WARNINGS).
Nausea
Depression
Hypersensitivity, including localized and generalized rash
Bronchospasm (predominantly in patients with pre-existing bronchospastic disease), respiratory failure (see WARNINGS)
Masked symptoms of hypoglycemia in insulin-dependent diabetics (see WARNINGS)
Signs and symptoms of keratitis, blepharoptosis, visual disturbances including refractive changes (due to withdrawal of miotic therapy in some cases), diplopia, ptosis. Other reactions associated with the oral use of nonselective adrenergic receptor blocking agents should be considered potential effects with ophthalmic use of these agents.
Carteolol Hydrochloride (carteolol) Ophthalmic Solution should be used with caution in patients who are receiving a beta-adrenergic blocking agent orally, because of the potential for additive effects on systemic beta-blockade. Close observation of the patient is recommended when a beta-blocker is administered to patients receiving catecholamine-depleting drugs such as reserpine, because of possible additive effects and the production of hypotension and/or marked bradycardia, which may produce vertigo, syncope, or postural hypotension.
