Effect of topical XXXX on aqueous dynamics in normal and @entity20388 .

@entity1009 @entity4088 @entity7462 @entity735 @entity4086 @entity20388
The effects of @entity4088 , an @entity4086 derivative, were studied on intraocular pressure (IOP), outflow facility, @entity7462 flow, and pupil size in monkeys. Unilateral topical administration of two 20-microliters drops of 0.1% @entity4088 significantly lowered IOP in the treated- and contralateral eye in both normal- and @entity20388 . In 12 normal monkeys, the baseline IOP of 18.3 +/- 0.4 mmHg [mean +/- S.E.(M.)] was maximally reduced to 14.4 +/- 0.7 mmHg in the treated eye (P less than 0.001) and 14.6 +/- 0.6 mmHg in the contralateral eye (P less than 0.001) at 2 hr after drug administration. In 10 monkeys made bilaterally glaucomatous by argon laser treatment of the trabecular meshwork, the baseline IOP of 33.9 +/- 3.0 mmHg [mean +/- S.E.(M.)] in the treated eyes and 31.7 +/- 3.3 mmHg in the untreated eyes maximally decreased to 23.9 +/- 2.2 mmHg (P less than 0.05) and 26.2 +/- 3.3 mmHg (P less than 0.005), respectively, at 5 hr. No significant change (P greater than 0.7) in outflow facility occurred in either eye of 11 normal monkeys 2 hr after unilateral 0.1% @entity4088 treatment. In six normal monkeys, the baseline @entity7462 flow of 1.58 +/- 0.20 microliter @entity1009 in treated eyes and 1.44 +/- 0.18 microliter @entity1009 in untreated eyes was reduced to 0.92 +/- 0.08 microliter @entity1009 (P less than 0.02) and 1.09 +/- 0.11 microliter @entity1009 (P greater than 0.10), respectively, from 0.5- to 3.5 hr after drug administration. A mydriatic response was observed in both eyes after unilateral treatment from 1- to 2 hr in eight normal monkeys. By the third day of treatment, bilateral twice a day 0.1% @entity4088 drops in eight @entity735 no longer significantly (P greater than 0.05) decreased IOP.
