Complete PRP combined with trabeculectomy with MMC can effectively reduce the elevated IOP in eyes with NVG. However, this combined treatment is not effective in eyes with proliferative membranes and retinal detachments.

Nipradilol is an alpha(1), beta-blocker with milder side effects than other beta-blockers used in humans. In this study the effects of nipradilol were compared with those of timolol maleate in dogs. Twelve clinically normal dogs (nine mongrels, two beagles, and one Akita) were used. We applied 0.25% nipradilol or 0.5% timolol maleate drops for a period of 28 days. Intraocular pressure (IOP) was measured before and after administration on the 2nd, 4th, 7th, 14th, 21st and 28th day. Blood pressure, pulse rate and coefficient of aqueous outflow (C-value) were also measured before and after administration on the 7th, 14th, 21st and 28th day. Both nipradilol and timolol maleate significantly lowered IOP from the 2nd day to the end of the study period. Nipradilol lowered IOP to an equivalent degree to timolol maleate. There was no significant change in blood pressure and pulse rate throughout the study period with administration of nipradilol. C-value showed a significant rise from the 14th day with administration of nipradilol, while it did not show any significant change during the study period with administration of timolol maleate. The reduction of IOP by nipradilol was similar to that by an existing beta-adrenergic antagonist, timolol maleate, but nipradilol was associated with fewer systemic side effects in dogs. Nipradilol appears to be a useful drug for treatment of glaucoma in dogs.

Objective The effect of a small amount of alcohol on the sleep structure in relation to alcohol sensitivity was examined using polysomnography (PSG).Methods Alcohol sensitivity was evaluated using alcohol patch test for all subjects. PSGs were performed on three nights after one night for acclimation, and subjects consumed no alcohol, 0.28 or 0.69 g ethanol/kg body weight, respectively, before going to bed. The percentages of sleep time in each sleep stage of 1, 2, 3+4 and rapid eye movement (REM), REM latency, and REM cycle were calculated.Subjects Thirteen healthy female students (age 21.1± 0.7 years) were enrolled in this study.Results In all subjects, there were no significant differences in any of the sleep parameters between baseline night and alcohol nights. Six of the 13 subjects were sensitive to alcohol, in whom %stage REM was significantly decreased by alcohol consumption (baseline night: 18.3± 6.2%, alcohol night I: 9.8±5.1% and alcohol night II: 11.0±2.8%), and the REM latency was significantly prolonged. The standard deviation of REM cycle was significantly greater on alcohol nights I and II than baseline night. There were no significant differences in other sleep parameters. In the other seven subjects who were insensitive to alcohol, none of the sleep parameters were significantly affected by alcohol consumption.Conclusion REM sleep was adversely affected by a small amount of alcohol in alcohol-sensitive healthy young women. Alcohol sensitivity might play some important role in impaired REM sleep by an ingestion of a small amount of alcohol.

Nonclinical toxicity that precludes the safe administration of tolvaptan to humans was not observed. However, appropriate cautions should be taken in women of childbearing potential.
