Abstract
The effect of long-term application of 4% atenolol eye drops has been studied in patients with either glaucoma or ocular hypertension. In some patients who show a good initial response the ocular hypotensive effect gradually wears off with long-term use. This pattern of response appears to be more frequent in patients with pretreatment intraocular pressure of 25 mmHg, or greater. In combination with atenolol miotics or adrenaline show an additive effect.
