Comparison of Latanoprost Vs. Timolol

The primary purpose of this study is to show, through a controlled masked clinical study of subjects with ocular hypertension (OHT), that latanoprost increases the low uveoscleral drainage of aqueous humor back to normal levels, and timolol maleate reduces the formation of aqueous humor below normal. Both of these mechanisms will effectively reduce intraocular pressure (IOP). The secondary purpose is to assess the effects of both latanoprost and timolol maleate on the fluorophotometric outflow facility, and episcleral venous pressure and on all parameters over time.
