In this article, we study skew cyclic codes over ring R = Fq + vFq + v 2 Fq, where q = p, p is an odd prime and v3 = v. We describe generator polynomials of skew cyclic codes over this ring and investigate the structural properties of skew cyclic codes over R by a decomposition theorem. We also describe the generator polynomials of the duals of skew cyclic codes. Moreover, the idempotent genera...

BACKGROUND The impact of strabismus on visual function, self-image, self-esteem, and social interactions might decrease health-related quality of life (HRQoL). This study aimed to evaluate the psychometric properties and clinical applications of two strabismus-specific HRQoL questionnaires in the cultural context of China. METHODS The Chinese versions of the Adult Strabismus Quality of Life Q...

PURPOSE To describe the clinical findings and long-term outcome of patients with chronic central serous chorioretinopathy (cCSC). MATERIALS AND METHODS This was a retrospective case series in 52 eyes of 36 patients with a follow-up period of at least 1 year. Extensive ophthalmic examination and a validated questionnaire concerning vision-related quality of life (National Eye Institute Visual ...

Purpose. Evaluate optimized fundus autofluorescence (FAF) imaging in early stages of diabetic retinopathy (DR) and relate findings with conventional colour fundus imaging and visual function in diabetic patients and control subjects. Materials and Methods. FAF and colour images were obtained using the CR-2 Plus digital nonmydriatic retinal camera in seven diabetic patients and thirteen control ...

PURPOSE Keratoconus is a chronic, noninflammatory disease of the cornea with onset in early adulthood. As these years are important to financial and social health, keratoconus may have more severe impact on quality of life than would be expected given its clinical severity. We examined the vision-related quality of life of patients in the Collaborative Longitudinal Evaluation of Keratoconus (CL...

PURPOSE To assess vision-related quality-of-life subscales with objective measurements of visual function in patients affected with retinitis pigmentosa of Bothnia type (BD). METHODS Forty-nine patients answered the NEI-VFQ-25 questionnaire. High- and low-contrast distance acuity (VA), near VA, and visual fields (VF) were measured. Weighted VA (WVA) and low-contrast (10%) VA (WLCVA), binocula...

BACKGROUND Although much research has been conducted on the impact of strabismus on the quality of life (QoL) of adults, the effect of this condition on teenagers has not been extensively studied. This study therefore aimed to assess the effect of strabismus on the vision-related QoL of Chinese teenagers. METHODS The Chinese version of the 25-item National Eye Institute Visual Function Questi...

Purpose To develop and validate the Functional Reading Independence (FRI) Index, a new patient-reported outcome measure assessing reading activities in individuals with geographic atrophy (GA) due to age-related macular degeneration. Methods The Index was developed through expert consultation and qualitative patient interviews. Reliability, validity, and responsiveness were tested with data f...
