โœฆ Synopsis

There is still debate about whether the ciliary muscle is innervated by the sympathetic nervous system. We investigated the amplitude and the dynamics of accommodation under influence of the non-selective beta-blocker timolol. For this purpose the variations in thickness of the human lens during step-like changes in accommodation were measured with high-resolution A-scan echography. Results showed that the dynamics of accommodation, expressed in the time constants of the response, were affected as well as the amplitude.

A double-masked study was carried out to assess the effect of timolol ophthalmic solution on corneal sensitivity in seven normal volunteers. No significant change in corneal sensitivity was demonstrated during four weeks of timolol administration. Corneal sensitivity was determined in two age-matche
