Ocular rigidity, outflow facility, ocular pulse amplitude, and pulsatile ocular blood flow in open-angle glaucoma: a manometric study.

Purpose: To compare ocular rigidity (OR) and outflow facility (C) coefficients in medically treated open-angle glaucoma (OAG) patients and controls, and to investigate differences in ocular pulse amplitude (OPA) and pulsatile ocular blood flow (POBF) between the two groups.

Methods: Twenty-one OAG patients and 21 controls undergoing cataract surgery were enrolled. Patients with early or moderate primary or pseudoexfoliative OAG participated in the glaucoma group.

Ocular rigidity, ocular pulse amplitude, and pulsatile ocular blood flow: the effect of axial length.

Purpose: Previous studies have shown a negative correlation between axial length (AL) and pulsatile ocular blood flow (POBF). This relation has been questioned because of the possible confounding effect of ocular volume on ocular rigidity (OR). The purpose of this study was to investigate the relation between AL, as a surrogate parameter for ocular volume, and OR, ocular pulse amplitude (OPA), and POBF.

Plasma and aqueous humour levels of ghrelin in open-angle glaucoma patients.

Background: To compare aqueous humour and plasma levels of ghrelin, a peptide recently identified in human eyes, in patients with open-angle glaucoma and controls.

Design: Cross-sectional, controlled, hospital-based study.

Participants: Twenty-four open-angle glaucoma (17 primary open-angle and 7 pseudo-exfoliation glaucoma) patients and 30 controls were included.
