The variable etiology of POAG poses significant challenges for treatment and rehabilitation. We analyzed a large POAG patient cohort during treatment to reveal possible causes of vision disorder, assess vision-related quality of life （VRQL）, and to evaluate the efficacy of rehabilitative treatments. Methods We analyzed the visional disturbances in 500 POAG patients （890 eyes） by regular ophthalmic examination and visual field examination using Humphrey 30-o perimetry. Appropriate rehabilitative treatments for POAG were prescribed based on results of clinical examination and included correction of ametropia, health education, counseling, and the fitting of typoscopes. VRQL was assessed before and after treatment by a VRQL self-assessment questionnaire. Results Scores on the VRQL self-assessment were significantly lower compared to healthy controls. The primary cause of the vision disturbances was ametropia （97.99%）, and 51.61% of the ametropia eyes had not received appropriate correction. The secondary causes of visual impairment were glaucomatous neurodegeneration （26.29%）, complicated cataract, or other accompanying eye diseases. The causes of the clinical low vision （44 patients） were glaucomatous neurodegeneration （32 eyes）, fundus diseases （23 eyes）, keratopathy （11 eyes）, and other eye diseases （10 eyes）. The VRQL scores of patients improved significantly after rehabilitation and the correction of ametropia （P 〈0.01）. Twenty-five patients with low vision were provided with typoscopes, and 21 （84%） experienced significant functional recovery, while the remaining low vision patients could see letter lines two or more levels lower （smaller） on visual charts in a near vision test. Conclusions Vision disorders in POAG patients are common and severe. Appropriate rehabilitation, especially the correction of ametropia, can significantly improve VRQL as revealed by the self-assessment of POAG patients.展开更多

文摘Pediatric uveitis is an inflammatory ocular disease that can lead to sight-threatening complications.Pediatric patients have distinct challenges in the diagnosis and management of uveitis,secondary to difficulties in performing ophthalmic examinations in young children,delayed diagnosis due to lack of adherence with recommended screening schedules,medication side-effects,and increased burden of disease into adulthood.Measurement of outcomes in pediatric uveitis has traditionally relied upon the ophthalmic examination and general quality of life(QOL)measures.However,the ophthalmic examination does not take into account the impact of uveitis on a child’s QOL and general QOL measures do not adequately assess the specific effects of vision.Several vision-related quality of life(VR-QOL)instruments have been used to measure outcomes in both adults and children including:the National Eye Institute Visual Function Questionnaire(NEI VFQ-25),Vision-related Quality of Life of Children and Young People(VQoL_CYP),the Children’s Visual Function Questionnaire(CVFQ),and the Effect of Youngsters’Eyesight on Quality of Life(EYE-Q).However,the NEI VFQ-25 is not a valid or applicable measure in children,and the VQoL_CYP and CVFQ are not uveitis specific and may not characterize disease specific burdens.The EYE-Q is the only uveitis-specific pediatric questionnaire that measures visual functioning and VR-QOL in 5-18 years old children and adolescents with uveitis.It has been shown to be a valid and reliable assessment tool in several cohorts of children with uveitis.A comprehensive assessment of the impact of uveitis on a child that includes a vision-specific measure,such as the EYE-Q,allows for better understanding of the true burden of uveitis in children.For this review,we describe traditional outcome measures in uveitis studies,general QOL measures and vision-specific measures in adults and in children.
