“…Nineteen items assess difficulty in performing tasks in relation to distance, near, and color vision, and visual field, and an item on the child’s global self-assessment of vision. The Cardiff Visual Ability Questionnaire for Children (CVAQC) measures the visual disability of children 5–18 years old, and the Impact of Vision Impairment for Children (IVI_C) measures the impact of VI on QOL in 8–18 year olds (28, 29). The Vision-related Quality of Life of Young Children and Young People (VQoL_CYP) is limited for use in those who are 10–15 years of age (30).…”

Objective To determine the validity and reliability of a novel questionnaire to measure vision related quality of life (VRQOL) in children 8–18 years old for use in juvenile idiopathic arthritis-associated uveitis (JIA-U) –Effects of Youngsters’ Eyesight on Quality of Life (EYE-Q). Methods Several steps validated the EYE-Q. We interviewed experts and children on how vision affects a child’s activities. We developed new items and selected relevant items from existing instruments. We administered initial versions of the EYE-Q to normal-sighted children and those with JIA-U. For this study, children with various (or no) ocular conditions were recruited from a clinical population. Visual acuity (VA) and contrast sensitivity were performed, and the EYE-Q and Pediatric Quality of Life Inventory (PedsQL) were administered. The EYE-Q was repeated 10 days later. Patients, parents and physicians rated vision severity. Results Of 120 patients, 48% were female, 46.7% had no visual impairment (VI), and 52% had bilateral eye involvement. Mean age was 11.3 years. There were significant differences in the measures based on VA (p<0.001). Children with more severe VA and bilateral eye involvement had worse EYE-Q scores (p<0.001). There were significant associations between the EYE-Q and PedsQL (r = 0.375), repeat EYE-Q (r = 0.864), and clinical measures of ocular disease (r = −0.620). Conclusions Our study provides evidence of the validity and reliability of the EYE-Q in the measurement of VRQOL. The EYE-Q may complement clinical measures of VI and overall QOL and become an important tool in the assessment of QOL in JIA-U.

“…Some of the items may not apply to children in the US because of differences in the US, UK, and Australian educational structures and content. Therefore, our child-specific comprehensive EYE-Q may offer significant improvements over existing measures and also over tools for adults (14, 18, 19, 28, 29, 31). …”

“…However, some of the mechanical and dynamic responses are still not fully understood due to the non-linearity and viscoelasticity of the tissues [2]. The tissue of interest in this study is the cornea , which contributes significantly to the optical focusing power of the eye and a vital area in refractive surgeries [3]- [5]. The air puff test conducted by the Ocular Response Analyser (ORA; Reichert, Inc., Buffalo, NY), the CorVis-ST (Oculus Optikgerate GmbH, Wetzlar, Germany) [6]- [8] and others, is a noncontact tonometry method with direct interaction with the cornea used to estimate intraocular pressure that is necessary for glaucoma management [9]- [11].…”

Purpose: To improve numerical simulation of the non-contact tonometry test by using Arbitrary Eulerian-Lagrangian deforming mesh in the coupling between computational fluid dynamics model of an air jet and finite element model of the human eye. Methods: Computational fluid dynamics model simulated impingement of the air puff and consisted of 25920 wedge6 elements and employed Spallart-Allmaras model to simulate capture turbulence of the air jet. The time span of the jet wais 30 ms and maximum Reynolds number
