[The role of ocular perfusion pressure in the course of primary open angle glaucoma in patients with systemic hypertension].

Unlabelled: Ocular perfusion pressure (OPP) is an estimate for the local intraocular blood flow, calculated as difference between the objective values for the diastolic or systolic systemic blood pressure (SBP) and intraocular pressure (IOP). Primary Open Angle Glaucoma (POAG) is an eye disorder that affects the optic nerve (ON) with progressive damage to full eye sight loss, being associated, but not always, with high intraocular pressure (IOP).

Aim: Numerous studies have pointed out that the intraocular vascular impairments could be a consequence of a broader, systemic blood flow alteration.

[Stage 3-5 chronic kidney disease--what is the real prevalence in Romania?].

Unlabelled: A high prevalence of reduced GFR has been reported in Western populations. However, little is known about the real prevalence of chronic kidney disease (CKD) in Eastern Europe. Our aims were 1) to identify the true burden of CKD in a large adult population sample; 2) to compare the GFR estimates by the "classic" MDRD4 formula with the GFR derived from the formula proposed recently by Levey.
