Study of the quality of life in patients with glaucoma

The purpose of the study was the assessment of the perception of the disease (glaucoma) and life quality (LQ) by a patient and interrelations between the objective parameters of visual functions and the self-assessment of the condition in patients with glaucoma. A total of 74 glaucoma patients were prospectively examined. The SF-36 russified version and adapted, by the authors, NEI-VFQ-25, 2000, method were made use of. Threshold testing 24-2 and Esterman's binocular screening test were used to detect any disorders in the peripheral vision. The study results are indicative of that the LQ parameters go down in patients with glaucoma according to both the results of the self-assessment of the health condition as a whole (SF = 36), and in relation with glaucoma (NEI-VFQ-25). The LQ parameters of NEI-VFQ-25 of glaucomatous patients are reliably lower as compared to the control group. A moderate statistically significant correlation was used to determine the LQ dependence on the peripheral vision changes virtually in all NEI-VFQ-25 scales. The LQ dependence on a degree of visual functions' disorders was found to be reliable; however, the LQ indices were notably reduced in glaucomatous patients without visual field defects, which was due to a changed psychological status.     

Utility values among glaucoma patients: an impact on the quality of life

AIM: To ascertain utility values and associated quality of life with different severity and duration of glaucoma among Indian patients. METHODS: Utility values of 105 consecutive patients with primary glaucoma of at least 12 months' duration were evaluated in a cross sectional study. Utility values were ascertained in five groups using both the time-trade off and standard gamble methods: group 1 (best corrected visual acuity in the better eye of 6/9 or better), group 2 (best corrected visual acuity in the better eye of 6/18 to 6/12), group 3 (best corrected visual acuity in the better eye of 6/36 to6/24), group 4 (best corrected visual acuity in the better eye of 3/60 to 6/60), and group 5 (best corrected visual acuity in the better eye of 3/60 or worse). RESULTS: The mean utility value for the glaucoma group as a whole was 0.64 (SD 0.69; 95% confidence interval (CI), 0.58 to 0.70) with the time-trade off method and 0.86 (SD 1.00; 95% CI, 0.81 to 0.90) with the standard gamble method for a gamble of death and 0.97 (SD 1.00; 95% CI, 0.94 to 0.99) for a gamble of blindness. The mean utility results by the time-trade off method were as follows: group 1 = 0.66, group 2 = 0.66, group 3 = 0.62, group 4 = 0.55, and group 5 = 0.61. The utility value was much lower (0.46) in those with no formal education or only primary education compared to those with postgraduate education (0.75) (p = 0.038). Those patients with glaucoma of less than 5 years' duration had a utility score of 0.62 while those with glaucoma for more than 10 years had a score of 0.74 (p = 0.40). CONCLUSIONS: Visual acuity loss occurring secondary to glaucoma is associated with a substantial decrease in patient utility value (and quality of life) in a developing country like India. The utility value is directly dependent on the degree of visual acuity loss associated with the disease and educational status and not on the duration of disease, the number of medications, or the visual field indices.     

Health-related quality of life in patients with cataract and glaucoma

The patient's perspective of his or her own health status as it relates to functioning and well-being is referred to as health-related quality of life. Various generic and ophthalmology-specific survey instruments have been used to gain an understanding of patient-oriented health status in patients with cataract or with glaucoma. Improvement in vision-targeted quality of life has been shown following cataract surgery; however, an improvement in self-perceived overall health status following cataract surgery has not been established. Increasing severity of glaucoma has been shown to be negatively related to vision-targeted quality of life; the relationship between increasing severity of glaucoma and overall self-perceived health status is inconclusive. Integration of the concepts of health-related quality of life into clinical practice will require the development of better measurement instruments that can demonstrate notable outcome advantages for patients.     

Evaluation of quality of life and priorities of patients with glaucoma

PURPOSE: To investigate the quality of life and priorities of patients with glaucoma. METHODS: Patients diagnosed with glaucoma and no other ocular comorbidity were consecutively recruited. Clinical information was collected. Participants were asked to complete three questionnaires: EuroQuol (EQ-5D), time tradeoff (TTO), and choice-based conjoint analysis. The latter used five-attribute outcomes: (1) reading and seeing detail, (2) peripheral vision, (3) darkness and glare, (4) household chores, and (5) outdoor mobility. Visual field loss was estimated by using binocular integrated visual fields (IVFs). RESULTS: Of 84 patients invited to participate, 72 were enrolled in the study. The conjoint utilities showed that the two main priorities were "reading and seeing detail" and "outdoor mobility." This rank order was stable across all segmentations of the data by demographic or visual state. However, the relative emphasis of these priorities changed with increasing visual field loss, with concerns for central vision increasing, whereas those for outdoor mobility decreased. Two subgroups of patients with differing priorities on the two main attributes were identified. Only 17% of patients (those with poorer visual acuity) were prepared to consider TTO. A principal component analysis revealed relatively independent components (i.e., low correlations) between the three different methodologies for assessing quality of life. CONCLUSIONS: Assessments of quality of life using different methodologies have been shown to produce different outcomes with low intercorrelations between them. Only a minority of patients were prepared to trade time for a return to normal vision. Conjoint analysis showed two subgroups with different priorities. Severity of glaucoma influenced the relative importance of priorities.     

Visual function and quality of life in Korean patients with glaucoma

The relationship between visual acuity, the level of visual field impairment, visual functioning, and the quality of life was evaluated in Korean patients with glaucoma. Forty-three consecutive glaucoma patients from the glaucoma service at Severance Eye and Ear Hospital were included in this study. Each subject underwent a vision-specific functional status questionnaire (VF-14), a modified VF-14 (VF'-14) and general quality-of-life questionnaires of the Medical Outcomes Study 36-Items Short Form Health Survey (SF-36). The visual acuity and visual field measurements with a Humphrey automated perimeter were taken within one month of the initial visit. The mean age of the subjects was 57.9 +/- 17.8. Among these patients, there were 23 males and 20 females. The mean deviation (MD) and the corrected pattern standard deviation (CPSD) by the automated perimeter in the eye with the better visual acuity were -5.87 +/- 5.16 dB and 3.92 +/- 2.74 dB respectively. The VF-14 and SF-36 scores were 41.28 +/- 14.56 and 52.39 +/- 6.61 respectively. There were significant correlations between the VF-14, VF'-14, and the MD of the better eye (p < 0.05). In Korean patients with glaucoma, the VF-14 and VF'-14 have significant relationship with the MD of the better eye in the visual field.     

Contribution of multiple glaucoma medications to visual function and quality of life in patients with glaucoma.

BACKGROUND: Previous studies examining the correlation between medical treatment and overall quality of life in patients with glaucoma assessed differences between a glaucoma population and a matched group (without glaucoma) and were not aimed specifically at detecting a relation between visual acuity, visual field status and medication use, and visual function and quality of life. We performed a study to determine this relation in patients with chronic open-angle glaucoma (COAG). METHODS: The study was cross-sectional. Of 235 English-speaking patients with a diagnosis of COAG, normal-pressure glaucoma or suspected glaucoma (receiving therapy) seen in a university-based glaucoma practice between Feb. 1 and Apr. 30, 1998, 224 (95.3%) agreed to participate. All subjects completed two questionnaires: the Visual Function Assessment and the EQ-5D, assessing health status (quality of life). Visual acuity, diagnosis, age, sex, country of birth, type and number of medications for topical and for oral use, dosage, and history of laser treatment and surgery were extracted from the medical record. Pearson rank correlation and multivariate analyses were performed. RESULTS: On univariate analysis visual function was correlated with age, visual acuity, number of glaucoma medications, number of applications of eyedrops, mean deviation in better eye, mean deviation in worse eye, and lower hemifield involvement in both eyes. On multivariate analysis only visual acuity and visual field status were independently associated with visual function. Univariate analysis showed that health status was correlated with age, visual function and number of medications for oral use; however, age failed to retain statistical significance in the regression analysis. INTERPRETATION: Our results suggest that the number of glaucoma medications is not predictive of quality of life.     

采用效用分析方法测量中国人青光眼患者的视觉相关生活质量

背景近年来关于青光眼对患者生活质量的影响日益受到临床工作者的关注,但调查结果表明各种视功能量表均存在一定的不足,准确、全面地评价影响青光眼患者生活质量的主观和客观因素值得深入研究。目的利用效用分析的方法测量青光眼患者视觉相关生活质量并初步分析其相关因素。方法收集北京同仁医院门诊确诊的青光眼患者,采用效用分析中的线性等级尺度（RS）法和时间交易（TTO）法进行问卷调查以获得反映青光眼患者疾病相关生活质量的效用值,比较RS法和TTO法所得效用值的差异和相关性,分析不同性别、年龄、受教育程度、工作状态、青光眼家族史、青光眼手术史、不同视功能损害程度以及不同青光眼类型对患者效用值的影响。结果研究共纳入青光眼患者86例,其中男62例,女24例;平均年龄44．67岁。RS法和TTO法测得青光眼患者的效用值分别为0．62±0．19和0．77±0．12,两种方法获得的效用值之间无显著相关关系（r=0．074,P=0．499）。RS法计算所得的效用值受日常生活视力、视野缺损程度以及青光眼手术史的影响,而TTO法测得的效用值主要与患者的年龄、工作状态以及受教育程度有关,与患者视力和视野损害的严重程度无相关性。校正了年龄、工作状态和受教育程度以后,较差眼视力≥0．3的青光眼患者其TTO效用值显著高于较差眼视力〈O．3者（P=0．029）。结论效用分析的方法简单、灵敏,可较好地被患者所接受。RS法所得效用值受日常生活视力、视野缺损程度以及青光眼手术史的影响,反映了患者对自身视觉状态的主观评价。TTO法测得的效用值主要与患者的年龄、工作状态以及受教育程度有关,反映了不同患病个体对自身视觉相关生活质量的主观评价。视功能的损害程度在青光眼患者的总体生活质量中不起决定性作用。     

Which quality of life score is best for glaucoma patients and why?

Background  

The glaucomas are generally asymptomatic diseases until they are very advanced. They affect 2% of the population over 40 years of age and therefore represent a significant public health issue. There have been a number of attempts to develop quality of life scales for the disease. This review discusses the pros and cons of these scales and suggests the best of the current ones for use in a clinical setting.

Quality of life in glaucoma patients

Glaucoma as a chronic and often asymptomatic disease in its early stages has a great influence on Quality of Life (QOL). Mostly because of disturbances in visual functions like damage to the visual field, lower visual acuity, the psychological impact of the diagnosis, side effects and the cost of treatment. Evaluation of QOL is very useful instrument which helps to decide about the ways of treatment. Especially if they are equally beneficial but have totally different psychological impact. Considering patients' needs, satisfying their expectations and education, there is a guarantee of keeping the therapeutic indications and high efficiency of treatment.
