Visual impairment is one of the most common clinical manifestations of Multiple Sclerosis (MS), and is strongly related to overall health-related quality of life (HRQOL) in MS and other disorders. However, the assessment of vision-specific HRQOL in patients with MS has been limited. The purpose of this study was to examine self-reported visual dysfunction in a clinically heterogeneous MS cohort...

PURPOSE The aim of this study was to compare a new diffractive trifocal toric lens with an apodized diffractive bifocal toric lens in terms of refractive and visual acuity (VA) outcomes, including low-contrast VA (LCVA), as well as the patient's visual function 3 months after implantation. PATIENTS AND METHODS This is a randomized prospective study involving bilateral implantation of a trifoc...

OBJECTIVES Although it is known that the carotenoid lutein can affect visual performance, we still have much to learn about its effect in occupational populations, like drivers. The aim of this study was to examine the effect of lutein supplementation on visual function in healthy drivers with long-term light exposure. METHODS The study was a randomized, double-blind, placebo-controlled, 1-y ...

Background: Visual impairment is one of the independent risk factors for falling among the elderly. Functional disabilities caused by vision disorders are the most common problems affecting the quality of life in this population. Therefore, vision self-management program (VSM) may be helpful for patients in reducing impairment and improving the quality of life. Aim: The present study aimed to i...

PURPOSE To evaluate the correlation between quality of vision (QOV) and visual function in glaucoma patients. PATIENTS AND METHODS The relationship between QOV and visual function was investigated in 200 Japanese glaucoma patients. QOV was assessed using the Japanese version of the 25-item National Eye Institute Visual Function Questionnaire. The better eye and the worse eye were defined base...

BACKGROUND The aim of this study is to summarize the design and methodology of a prospective, longitudinal, observational cohort study to investigate how glaucoma affects patients' quality of life and visually-related function over a 4-year period. METHODS/DESIGN One hundred sixty-one (161) subjects were enrolled in this ongoing study. Patients between the ages of 21-85 years with a minimum 2...

PURPOSE To evaluate postoperative metamorphopsia in macula-off rhegmatogenous retinal detachment (RRD) and its association with visual function, vision related quality of life, and optical coherence tomography (OCT) findings. METHODS 45 patients with primary macula-off RRD were included. At 12 months postoperatively, data on metamorphopsia using sine amsler charts (SAC), best corrected visual...

BACKGROUND Impaired low-contrast visual acuity (LCVA) is common in multiple sclerosis (MS) and other neurological diseases. Its assessment is often limited to selected contrasts, for example, 2.5% or 1.25%. Computerized adaptive testing with the quick contrast-sensitivity function (qCSF) method allows assessment across expanded contrast and spatial frequency ranges. OBJECTIVE The objective of...

INTRODUCTION Retinitis pigmentosa (RP) is an inherited retinal disorder, characterized by photoreceptor degeneration inducing progressive vision loss. This study evaluates its impact on quality of life (QOL) and emotional states of patients affected by RP. METHODS A cross-sectional study was conducted on 60 RP patients diagnosed with rod-cone dystrophy and on 20 control subjects. The RP popul...
