Purpose: To translate and validate the Adult Strabismus 20 (AS-20) questionnaire, a health-related quality of life questionnaire specifically devised for patients with strabismus.

Methods: The AS-20 was translated in accordance with the principles of good practice for the translation and cultural adaptation process for patient-related outcomes (PRO) according to the methodology recommended by the International Society for Pharmacoeconomics and Outcome Research (ISPOR). The translation, evaluation, and validation were performed in several steps.

Article Synopsis
  • Keratoconus (KC) is a condition causing the cornea to thin and bulge, leading to vision problems, and its causes, particularly for sporadic cases, are still not fully understood.
  • This study included 176 patients with sporadic KC and a control group of 418 individuals to analyze genetic variants linked to KC using DNA samples.
  • The research found significant links between specific genetic variants (SNPs) in the FOXO1 and BANP-ZNF469 genes and sporadic KC, supporting previous findings from other populations.

Purpose: To evaluate the effect of glaucoma on vision-related quality of life (VRQoL), lifestyle, physical factors and socioeconomic status in a 70-year-old population in Gothenburg, Sweden.

Methods: Responses to questionnaires (N = 1182) between groups with and without self-reported glaucoma were analysed. Questionnaires included National Eye Institute Visual Functioning Questionnaire (NEI VFQ-25), Short-Form Health Survey (SF-36), physical activity, socioeconomics, alcohol and tobacco consumption.

Purpose: To determine the prevalence of and risk factors for open-angle glaucoma in a population of 70-year-olds in Gothenburg, Sweden and to compare the visual function between the glaucoma population and the non-glaucoma population.

Methods: Of the entire cohort (n = 1203), 1182 participants responded a questionnaire on self-reported glaucoma and were tested for blood pressure (BP) and diabetes. In all, 560 participants underwent ophthalmic examination including best-corrected visual acuity (BCVA), intraocular pressure (IOP), central corneal thickness (CCT), contrast sensitivity (CS), perimetry and photos of the retina and lens.

Purpose: The study aimed at determining the prevalence and sex differences in cataract, pseudophakia, lens opacities and self-reported cataract in 70-year-old people in Gothenburg, Sweden. The purpose was also to identify correlations between lens opacities, visual acuity and subjective visual function, and to validate self-reported cataract and cataract surgery.

Patients And Methods: Population-based cross-sectional study where participants (n=1182) answered questions about self-reported diagnosis of cataract and cataract surgery.

Purpose: To investigate vision-related quality of life (VRQoL), visual function and predictors of poor vision in a population of 70-year-olds.

Methods: Self-reported ocular morbidity and responses to the National Eye Institute Visual Functioning Questionnaire-25 (NEI VFQ-25) in a cross-sectional population study (N = 1203) in Gothenburg, Sweden, were compared with results from ophthalmic examination (N = 560).

Results: The most common self-reported ophthalmic morbidities were cataract (23.
