Measurement of health-related quality of life with glaucoma: validation of the Glau-QoL 36-item questionnaire.

Purpose: To validate a glaucoma-specific health-related quality of life (HRQoL) questionnaire: the Glau-QoL.

Methods: Patients with ocular hypertension (OHT) or glaucoma took part in a cross-sectional psychometric validation study (n = 573) and a separate reproducibility study (n = 244). Patients answered the 36-item Glau-QoL, designed from in-depth patient interviews.

Regulation of optic nerve head blood flow in normal tension glaucoma patients.

Purpose: To investigate the regulation of the optic nerve blood flow (Fonh) in response to an increase of the perfusion pressure (PPm) in normal tension glaucoma (NTG) patients and in age-matched normal volunteers.

Methods: Measurements were performed in 16 eyes of NTG patients and in 10 eyes of age-matched controls. Laser Doppler flowmetry (LDF) was applied to calculate the relative flux of red blood cells at the temporal rim of the optic nerve head (ONH) in response to increases in PPm.

[Glaucoma and quality of life].

Glaucoma is a serious ocular disorder potentially leading to blindness. Measuring the quality of life of patients with glaucoma is important because it makes it possible to evaluate the impact of the disease and its treatment on the patient's everyday life. Hitherto, this was done using generic scales, or those developed for other diseases; but no scale suitable for glaucoma was available.

[Creating a specific quality-of-life questionnaire in patients with glaucoma: item generation].

The methods for developing Health-Related Quality-of-Life (HRQoL) measures and their application in medical research have demonstrated their utility in various chronic, progressive, or life-threatening diseases. The efforts made to allow the patient's perspective to be included in the methodological framework of evidence-based medicine have been successful. The assumption of a strong relationship between clinical status and daily life is certainly valid in ophthalmology.

Apolipoprotein E-promoter single-nucleotide polymorphisms affect the phenotype of primary open-angle glaucoma and demonstrate interaction with the myocilin gene.

Primary open-angle glaucoma (POAG) is an optic neuropathy that has a high worldwide prevalence and that shows strong evidence of complex inheritance. The myocilin (MYOC) gene is the only one that has thus far been shown to have mutations in patients with POAG. Apolipoprotein E (APOE) plays an essential role in lipid metabolism, and the APOE gene has been involved in neuronal degeneration that occurs in Alzheimer disease (AD).
