[Systemic complications of beta-blocking eyedrops. Apropos of 6 cases].
Six cases of systemic reactions to topical treatment with beta-blocking eyedrops are reported, bradycardia and faintness due to an overdosage of ophthalmic timolol; decompensated heart failure one month after the prescription of carteolol eyedrops: bronchospasm after two weeks of treatment with metipranolol eyedrops; crippling Raynaud's phenomenon of otherwise unknown origin, which had begun with timolol eyedrops, continued with carteolol eyedrops and regressed after discontinuation of ophthalmic beta-blockers; aggravation of an anaphylactoid shock in a patient treated with ophthalmic timolol, and myocardial infarction possibly due to the abrupt withdrawal of timolol eyedrops. It cannot be overstressed that the rules governing the prescription of oral beta-blockers also apply to ophthalmic preparations of these drugs: respect of contra-indications, strict adherence to the dosage recommended, gradual drug withdrawal and regular supervision. Only controlled studies and long-term follow-up will be able to demonstrate differences in safety between the five beta-blockers commercialized as eyedrops in this country.
