PURPOSE The aim of the study was to assess the vision-specific quality-of-life (VS-QoL) of Greek glaucoma patients, and the impact of potential influencing factors. METHODS This was a 2-center, cross-sectional study. One hundred twenty-one patients were recruited from the outpatient glaucoma service and 100 successfully responded to the self-administered,(More)
PURPOSE The aim of our study was to investigate the biomechanical properties of the cornea in primary congenital glaucoma (PCG) and to identify the potential ocular determinants, which affect the corneal biomechanical metrics. METHODS Corneal hysteresis (CH), corneal resistance factor (CRF) and central corneal thickness (CCT) were measured in 26 patients(More)
BACKGROUND The aim was to assess the intra-session, inter-session and inter-observer repeatability of curvature and aberrometric measurements of Pentacam-derived posterior corneal surface in normal control (CG), keratoconic (KCG) and after corneal collagen cross-linked (CXLG) groups. METHODS This was a prospective, clinic-based, observational study that(More)
INTRODUCTION Corneal collagen cross-linking is a rather new technique that uses riboflavin and ultraviolet A light for collagen fiber stabilization in keratoconus corneas. Other than reversible side effects, the preliminary results of corneal collagen cross-linking studies suggest that it is a rather safe technique. In this report, we demonstrate a case of(More)
PURPOSE To assess the effect of stage 1 keratoconus (KC) and of the 2 prevalent KC therapeutic options: (1) corneal collagen cross-linking (CXL) and (2) CXL combined with topography-guided photorefractive keratectomy (t-PRK) on self-reported quality of life (QOL) by means of the 25-item National Eye Institute Visual Function Questionnaire (NEI-VFQ 25).

PURPOSE To evaluate the therapeutic effect of corneal cross-linking (CXL) in 2 cases of bullous keratopathy combined with corneal ulcer. METHODS Two patients (2 eyes) were recruited for the sake of the study. Both suffered from bullous keratopathy and presented a gradually deteriorating, vision-threatening, central corneal ulcer, despite intense local(More)
Corneal collagen cross-linking (CXL) using riboflavin and ultraviolet-A irradiation is a common method of tissue stabilization and has been developed primarily to address the need of treating keratoconus. CXL's promising results on keratoconus indicated that it might be effective in other corneal diseases as well. This new treatment promises a slowing(More)
BACKGROUND To evaluate the reliability and construct validity of a Greek version of the NEI-VFQ-25 in patients with chronic ophthalmic diseases. METHODS We developed the Greek version of the instrument using forward and backward translation. One hundred-eighty-six patients responded to the questionnaire. To examine reliability, Cronbach's alpha for each(More)
BACKGROUND The purpose of this study is to examine the repeatability of Pentacam-derived anterior chamber volume measurements, and assess the level of agreement of anterior chamber volume measurements obtained with the Visante and the Pentacam imaging devices. METHODS Anterior chamber volume was calculated with the Pentacam device and the Visante using(More)
PURPOSE To evaluate the contribution of reference bodies for elevation maps in diagnosis of keratoconus (KC) and forme fruste keratoconus (FFK). METHODS Study groups included (1) 80 eyes with KC, (2) 55 eyes with FFK, and (3) 95 eyes as control eyes. The maximum elevation value at the central 5 mm of the posterior cornea (MEL) and the elevation value at(More)
