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)
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)
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 To quantify the levels of tissue inhibitor of metalloproteinase 4 (TIMP4) and its ratios with free metalloproteinases (MMP) in the aqueous humor of patients with primary open angle glaucoma (POAG), pseudoexfoliation syndrome (PXS) and pseudoexfoliative glaucoma (PXG) and to evaluate a possible imbalance between MMPs and TIMPs in these samples.

Purpose of the study was to develop and assess a novel controlled drug delivery system of latanoprost acid (LA). Poly(lactide)/Monomethoxy-poly(ethyleneglycol) (PLA-PEG) nanoparticles (NPs) were prepared using an emulsification-solvent evaporation technique. NPs were characterized in vitro according to their size, ζ-potential, drug entrapment efficiency and(More)
PURPOSE To evaluate the diagnostic capacity of the Ocular Response Analyser's keratoconus match index (KMI) and keratoconus match probability (KMP) classification in a sample of keratoconus (KC) patients. METHODS Keratoconus match index and KMP from 114 KC eyes, randomly selected from 114 patients with bilateral keratoconus (KCG), were compared with the(More)
To evaluate and compare the recorded IOP values of the Pascal dynamic contour tonometer (PDCT) and the Goldmann applanation tonometer (GAT) after photorefractive keratectomy (PRK) and laser in situ keratomileusis (LASIK). Three groups of 84, 182 and 43 patients each were treated by PRK for myopia, LASIK for myopia and LASIK for hyperopia respectively.(More)
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 lack of physical activity, along with obesity, smoking, hypertension and hyperglycaemia are considered as risk factors for the occurrence of diseases such as diabetes. Primary objective of the study was to investigate potential correlation between physical activity and diabetic retinopathy. PATIENTS AND METHODS Three hundred and twenty(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)
