Abstract
The effects of S-596 and coarteolol, new beta-adrenergic blockers, were studied by means of the oral fluorescein method. Transfer coefficients by diffusion,k d ⋅ pa, and by flow,k fa, were estimated in a total of 11 normal young volunteers, in whom the drug was instilled in one eye and the placebo in the fellow eye. With 0.5% dl-S-596,k d ⋅ pa increased to 124 ± 9% (mean ± SD) andk fa decreased to 67 ± 10% of the control eye. With 1% dl-carteolol,k d ⋅ pa increased to 121 ± 4%, andk fa decreased to 84 ± 11% of the control eye. Both S-596 and carteolol increased iris permeability and decreased the aqueous flow rate significantly.
In a group of 13 cases, intracapsular extraction of senile cataract was carried out with postoperative routine instillations, and in another group of 7 cases, it was carried out with additional topical flurbiprofen, a new nonsteroidal anti-inflammatory drug. Flurbiprofen ophthalmic solution (0.1%) was instilled 3, 2, 1, and 0.5 h before the surgery and 4 times a day postoperatively. On the 6th postoperative day, a fluorophotometric study was carried out using oral fluorescein, and a coefficient that reflects the permeability of the blood-aqueous barrier after the cataract surgery was calculated. It was found that additional topical flurbiprofen considerably suppresses the disruption of the blood-aqueous barrier.
