Abstract
Elevated intraocular pressure was always hold as main etiopathogenetics factor which causes the glaucoma. Tendency to lower intraocular presure was considered as the main philosophy of conservative treatment of glaucoma in the past.
In this point of view it has been changed a lot at last passed years. Glaucoma is thought to be multifactorial disease and the high intraocular pressure is one of its risk factors – high intraocular pressure is too high to provide sufficient blood-flow through the optic nerve disc.
Sufficient blood flow through the optic disc is necessary to preserve changeless visual acuity. As an ideal medicament should be considered the one which is satisfyingly safe for the patient, has a minimum of advers events, lower IOP at the levels well secure for the eye, improve blood flow through the optic nerve head and enhance hemodynamic parameters.
