[A comparative study of the ocular hypotonic action of collyria with oxprenolol and timolol maleate].

Comparison of the decrease in intraocular tension in a group of 25 patients show that the collyria of oxprenolol, 0.25%, led to an average decrease of 6.36 mmHg, whereas that of thymolol maleate, 0.25%, to a decrease of 8.76 mmHg. Both decreases were statistically significant versus the initial intraocular tension.
