Influence of continuous 4C nursing on quality of life and self-care ability of patients with diabetes retinopathy: An observational study.

This study aims to investigate the impact of continuous 4C nursing on patients with diabetes retinopathy (DR) and its influence on self-care ability. A total of 100 DR patients admitted to our hospital from October 2020 to October 2022 were randomly divided into a control group and an observation group, with 50 cases in each group. The control group received routine care, while the observation group received continuous 4C care. The nursing effects of both groups were compared. After nursing, the observation group showed a lower self-rating anxiety scale score and a higher self-care ability scale score compared to the control group (P < .05). The SQQL-VI scores for all social activities were also higher in the observation group (P < .05). Additionally, the observation group had lower levels of fasting blood glucose, 2-hour postprandial blood glucose, and glycated hemoglobin than the control group (P < .05). Moreover, the observation group had higher visual acuity and lower intraocular pressure than the control group (P < .05). The visual impairment rate was lower and the overall compliance rate was higher in the observation group compared to the control group (P < .05). After nursing, both groups showed improvements in symptoms, visual function, physical function, psychological and social activity scores, visual acuity, and patient satisfaction scores. The observation group showed greater improvements compared to the control group (P < .05). The application of continuous 4C nursing in DR patients has shown positive effects, including improved patient compliance and satisfaction, enhanced patient quality of life and visual acuity. These findings suggest that continuous 4C nursing should be widely promoted and applied in clinical practice.

Patients Perceptions of Artificial Intelligence in a Deep Learning-Assisted Diabetic Retinopathy Screening Event: A Real-World Assessment.

During an artificial intelligence (AI)-assisted diabetic retinopathy screening event, we performed a survey on patients´ perceptions on AI. Respondents were individuals with diabetes, mostly followed in primary healthcare with a low education level. While 49.6% of participants said they knew what AI was, only 14% reported good or expert knowledge of AI. The vast majority reported positive feelings towards AI in healthcare. We highlight the importance of understanding patients´ views regarding AI in health in a real-life situation and emphasize the importance of digital education.

THE IMPACT OF BILATERAL VISION STATUS ON VISION-RELATED QUALITY OF LIFE IN PEOPLE WITH DIABETES MELLITUS.

PURPOSE: To assess the impact of bilateral vision status on vision-related quality of life (VR-QOL) in patients with Type 2 diabetes in a Chinese cohort. METHODS: Patients with presenting visual acuity (PVA) and VR-QOL data from the Fushun Diabetic Retinopathy Cohort Study were included. Vision-related quality of life was assessed using the National Eye Institute Visual Function Questionnaire-25. Monocular PVA (Snellen) was categorized into three levels for both the better-seeing eye and worse-seeing eye: 1) high PVA (H, > 6/18); 2) moderate PVA (M, 6/18-6/60); and 3) low PVA (L, < 6/60). Based on the monocular PVAs, six categories of bilateral vision status were defined (H-H, H-M, H-L, M-M, M-L, and L-L). The parameters of VR-QOL were analyzed between the groups. RESULTS: A total of 1,717 patients were enrolled. For better-seeing eyes in the same PVA level, the Visual Function Questionnaire-25 composite score decreased significantly with declining PVA in the worse-seeing eye (H-M vs. H-L: 80.5 ± 17.9 vs. 73.6 ± 22.5, P = 0.01; M-M vs. M-L: 78.7 ± 19.6 vs. 69.1 ± 26.4, P = 0.01). Conversely, for worse-seeing eyes in the same PVA level, there was no significant difference in the Visual Function Questionnaire-25 composite score as PVA changed in the better-seeing eye (H-M vs. M-M, 80.5 ± 17.9 vs. 78.7 ± 19.6, P = 0.30; H-L vs. M-L: 73.6 ± 22.5 vs. 69.1 ± 26.4, P = 0.25). CONCLUSION: The PVA of the worse-seeing eye in bilateral vision has a greater impact on VR-QOL in diabetic patients. Priority treatment may be considered for the worse-seeing eye for diabetic patients with different bilateral vision statuses, to better improve VR-QOL.

The effect of psychotherapy on anxiety, depression, and quality of life in patients with diabetic retinopathy: A protocol for systematic review and network meta-analysis.

BACKGROUND: Diabetic retinopathy (DR) is one of the common microvascular complications in diabetic patients, which is characterized by progressive development and often leads to irreversible visual impairment. More seriously, DR patients suffer great psychological stress due to impaired visual function and reduced self-care ability such as anxiety and depression, which seriously affect the quality of life of patients. In recent years, various psychological therapies have been applied to alleviate anxiety, depression, and quality of life in DR patients, which have achieved positive results. However, the effectiveness and safety of different psychological therapies are unclear. This study aims to assess the effects of psychotherapy on anxiety, depression, and quality of life in DR patients through a network meta-analysis. METHODS: All randomized controlled trials (RCTs) on the effects of psychotherapy on anxiety, depression, and quality of life in patients with DR published before 30 November 30, 2021, will be searched in the PubMed, EMBASE, Cochrane Register of Controlled Trials, Web of Science, Chinese Scientific Journal Database, China National Knowledge Infrastructure Database, Wanfang, and China Biomedical Literature Database. There will have no restrictions on publication status and language. Two researchers will be independently responsible for RCT screening, data extraction, and quality evaluation. All statistical analyses will be performed using Stata 14.0 and R 4.1.2. RESULTS: The results of this meta-analysis will be submitted to a peer-reviewed journal for publication. CONCLUSION: This study will provide comprehensive and reliable evidence-based references for elucidating the efficacy of psychotherapy on anxiety, depression, and quality of life in DR patients. ETHICS AND DISSEMINATION: Ethical approval was not required for this study. The systematic review will be published in a peer-reviewed journal, presented at conferences, and shared on social media platforms. OSF REGISTRATION NUMBER: DOI 10.17605/OSF.IO/K8T27.

Screening for diabetic retinopathy with different levels of financial incentive in a randomized controlled trial.

AIMS/INTRODUCTION: To examine the impact of different levels of financial incentive in terms of fee subsidization on diabetic retinopathy screening in the private primary care setting in Hong Kong. MATERIALS AND METHODS: All general practitioners working in the private sector and registered in two electronic public databases were invited to participate. Consecutive patients with diabetes mellitus were then recruited by the participating practitioners. The recruited participants were randomly allocated to one of three screening groups with different fee levels (HK$0, HK$150 [US$19], HK$300 [US$39]) in a randomized controlled trial. Screening uptake and severity of diabetic retinopathy detected were compared. RESULTS: Out of 1,688 eligible practitioners, 105 participated and invited 402 patients, with 239 initially agreeing to participate (59.5%). After randomization, 78, 75 and 76 participants in the HK$0, HK$150 and HK$300 fee groups, respectively, reconfirmed their participation and were offered screening at the relevant fee. The uptake of screening was 79.5% (62/78), 81.3% (61/75) and 63.2% (48/76), in the HK$0, HK$150 and HK$300 groups, respectively (P < 0.018). Being in the HK$150 fee group was associated with higher uptake of screening than being in the HK$300 fee group (odds ratio 2.31, P = 0.039). No significant difference was found in the prevalence of any diabetic retinopathy (33.9%, 27.9% and 37.5%, P = 0.378) or sight-threatening diabetic retinopathy (4.8%, 8.2% and 16.7%; P = 0.092) among the groups. CONCLUSION: A screening fee of HK$150, representing approximately a half subsidy, appears to be as effective in maximizing uptake as a full subsidy (HK$0) and without deterring those at high risk of diabetic retinopathy from screening.

Association of Cognitive Function and Retinal Neural and Vascular Structure in Type 1 Diabetes.

CONTEXT: Cognitive dysfunction is a growing and understudied public health issue in the aging type 1 diabetic population and is difficult and time-consuming to diagnose. Studies in long duration type 1 diabetes have reported the presence of proliferative diabetic retinopathy was associated with cognitive dysfunction. OBJECTIVE: This study assessed whether structural and vascular abnormalities of the retina, representing an extension of the central nervous system, are associated with cognitive impairment and other complications of type 1 diabetes. METHODS: An observational cross-sectional study of individuals with 50 or more years of type 1 diabetes (Joslin Medalist Study) was conducted at a university hospital in the United States. The study included 129 participants with complete cognitive testing. Validated cognitive testing measures included psychomotor speed, and immediate, and delayed memory. Optical coherence tomography (OCT) and OCT angiography (OCTA) were performed to obtain neural retinal layer thicknesses and vascular density for superficial (SCP) and deep retinal capillary plexus (DCP). Multivariable modeling was adjusted for potential confounders associated with outcomes in unadjusted analyses. RESULTS: Decreased vessel density of the SCP and DCP was associated with worse delayed memory (DCP: P = .002) and dominant hand psychomotor speed (SCP: P = .01). Thinning of the retinal outer nuclear layer was associated with worse psychomotor speed both in nondominant and dominant hands (P = .01 and P = .05, respectively). Outer plexiform layer thickness was associated with delayed memory (P = .04). CONCLUSION: These findings suggest that noninvasive retinal imaging using OCT and OCTA may assist in estimating the risks for cognitive dysfunction in people with type 1 diabetes.

The prevalence of depressive symptoms and related risk factors among diabetic patients with retinopathy attending the Jordan University Hospital.

OBJECTIVES: To investigate the prevalence of depressive symptoms among diabetic patients suffering from retinopathy, and to identify crucial risk factors that affect patients' quality of life and whether social support mediates the relationship between retinopathy and depression. METHODS: The sample comprises 155 participants with diabetic retinopathy recruited from the Jordan University Hospital during the year 2017. Arabic versions of all study tools were employed as follows: the Beck Depression Inventory; the short form of the health survey; the Berlin social support scale; ophthalmic examinations; patients' records; and a demographic questionnaire. ANALYSES: Descriptive statistics, the Pearson correlation, linear regression using SPSS, and mediation analysis using the Sobel test were applied. In addition, the odds ratio analysis and qualitative analyses for the open-ended questions were included. RESULTS: In general, 13 (8.9%) of our patients did not manifest any symptoms of depression while 42 (27.1%) had a mild mood disturbance, 26 (16.8%) were on the borderline of clinical depression, 47 (30.3%) had moderate depression, 22 (14.2%) with severe depression, and 5 (3.2%) had extreme depression. The results indicate a nonsignificant positive correlation between social support and health-related quality of life and a nonsignificant positive relationship between retinopathy severity and depression. Meanwhile, our results revealed a significant negative relationship between depression and social support and a nonsignificant negative relationship between retinopathy severity and social support. CONCLUSION: Our findings suggest that diabetic patients with retinopathy have a higher risk of developing depression. Hence, psychological interventions are highly needed to meet the mental health needs of these patients.

Synergy between the pay-for-performance scheme and better physician-patient relationship might reduce the risk of retinopathy in patients with type 2 diabetes.

AIMS/INTRODUCTION: This study investigated whether participation by patients with type 2 diabetes in Taiwan's pay-for-performance (P4P) program and maintaining good continuity of care (COC) with their healthcare provider reduced the likelihood of future complications, such as retinopathy. MATERIALS AND METHODS: The analysis used longitudinal panel data for newly diagnosed type 2 diabetes from the National Health Insurance claims database in Taiwan. COC was measured annually from 2003 to 2013, and was used to allocate the patients to low, medium and high groups. Cox regression analysis was used with time-dependent (time-varying) covariates in a reduced model (with only P4P or COC), and the full model was adjusted with other covariates. RESULTS: Despite the same significant effects of treatment at primary care, the Diabetes Complications Severity Index scores were significantly associated with the development of retinopathy. After adjusting for these, the hazard ratios for developing retinopathy among P4P participants in the low, medium and high COC groups were 0.594 (95% confidence interval [CI] 0.398-0.898, P = 0.012), 0.676 (95% CI 0.520-0.867, P = 0.0026) and 0.802 (95% CI 0.603-1.030, P = 0.1062), respectively. Thus, patients with low or median COC who participated in the P4P program had a significantly lower risk of retinopathy than those who did not. CONCLUSIONS: Diabetes care requires a long-term relationship between patients and their care providers. Besides encouraging patients to participate in P4P programs, health authorities should provide more incentives for providers or patients to regularly survey patients' lipid profiles and glucose levels, and reward the better interpersonal relationship to prevent retinopathy.

Baseline Diabetes Knowledge Assessment Amongst Adults With Type 1 and Type 2 Diabetes Receiving Eye Care at a Tertiary Ophthalmic Centre in Canada.

OBJECTIVES: The aim of this work was to assess the current state of baseline knowledge of diabetes and diabetic retinopathy (DR) in new patients referred to a tertiary retina service from their primary eye care provider. METHODS: This single-centre, prospective, observational study included patients presenting to the retina clinic at the Hamilton Regional Eye Institute, a major tertiary referral centre, for their initial consultation for diabetes- or DR-associated complications. Upon recruitment into the study, patients were asked to complete a 35-item questionnaire regarding diabetes and associated complications. All data were coded and analyzed using statistical software. RESULTS: A total of 98 patients participated in the study, which included 50 men and 48 women. Seventy-eight patients (79.6%) were Caucasian. We found that 56.1% (n=55) of the patients did not know the meaning of "HbA1C" (glycated hemoglobin) and only 26.5% of patients sampled were aware of their DR status. Bivariate analysis revealed that patients who had postsecondary education (p<0.001) or those who had education on complications of diabetes (p<0.05) were more likely to know their DR status. More importantly, it was found that 56.1% of patients expressed interest in a future diabetes seminar. CONCLUSIONS: It is evident that a significant proportion of patients do not have adequate knowledge of diabetes or DR, and this is related to their level of education and lack of being taught about diabetes complications. Our findings may guide prevention initiatives by primary eye care providers and promote increased awareness about diabetes and DR for prevention of disease complications, including blindness.

Knowledge, attitudes and eye health-seeking behaviours in a population-based sample of people with diabetes in rural China.

AIMS: To assess knowledge of diabetes and acceptance of eye care among people with diabetes in rural China, to improve service uptake. METHODS: Population-based study of people in Guangdong, China, with glycosylated haemoglobin A1c≥6.5% and/or known history of diabetes. Between August and November 2014, participants answered a questionnaire (based on Delphi process/previous focus groups) on medical history, demographic characteristics, self-rated health and vision, knowledge about diabetes and diabetic retinopathy, quality of local healthcare, barriers to treatment, likely acceptance of eye exams and treatment, and interventions rated most likely to improve service uptake. Presenting visual acuity was assessed, fundus photography performed and images graded by trained graders. Potential predictors of accepting care were evaluated and confounders adjusted for using logistic regression. RESULTS: A total of 562 people (9.6% (256/5825), mean age 66.2±9.84 years, 207 (36.8%) men) had diabetes, 118 (22.3%) previously diagnosed. 'Very likely' or 'likely' acceptance of laser treatment (140/530=26.4%) was lower than for eye exams (317/530=59.8%, p<0.001). Predictors of accepting both exams and laser included younger age (p<.001) and prior awareness of diabetes diagnosis (p=0.004 and p=0.035, respectively). The leading barrier to receiving diabetes treatment was unawareness of diagnosis (409/454, 97.2%), while interventions rated most likely to improve acceptance of eye exams included reimbursement of travel costs (387/562, 73.0%), video or other health education (359/562, 67.7%) and phone call reminders (346/562, 65.3%). CONCLUSIONS: Improving diagnosis of diabetes, along with incentives, education and communication strategies, is most likely to enhance poor acceptance of diabetic eye care in this setting.

Implementation and sustainment of a statewide telemedicine diabetic retinopathy screening network for federally designated safety-net clinics.

CONTEXT: Diabetic retinopathy (DR) is the leading cause of incident blindness among working-age adults in the United States. Federally designated safety-net clinics (FDSC) often serve as point-of-contact for patients least likely to receive recommended DR screenings, creating opportunity for targeted interventions to increase screening access and compliance. STUDY DESIGN AND METHODS: With such a goal, we implemented and assessed the longitudinal performance of an FDSC-based telemedicine DR screening (TDRS) network of 22 clinical sites providing nonmydriatic fundus photography with remote interpretation and reporting. Retrospective analysis of patient encounters between February 2014 and January 2019 was performed to assess rates of pathology and referral. A generalized estimating equation logistic regression model was used for subset analysis from audits of pre- and post-implementation screening rates. Finally, patient surveys were conducted and assessed as a measure of intervention acceptability. RESULTS: Of the 13,923 individual telescreening encounters (4327 female, 4220 male, and 5376 unspecified; mean [SD] age, 54.9 [12.5] years) studied, 10,540 were of adequate quality to identify 3532 (33.5%) patients with ocular pathology: 2319 (22.0%) patients had some level of DR with 1604 (15.2%) requiring specialist referral, and 808 (7.7%) patients required referral for other ocular pathologies. The mean screening rate for audited clinics in the year prior to program implementation was 29.9% (641/2147), which increased to 47.7% (1012/2124) in the program's first year, doubling patients' odds of being screened (OR 2.2; 95% CI: 1.3-3.7; P = .003). These gains were sustained over four years following implementation (OR 1.9; 95% CI: 1.1-3.1; P = .018) despite varied clinic screening performance (4-year averaged range, 22.9-55.1%). Odds of early detection likewise doubled for patients with consecutive screenings (OR 2.2, 95% CI: 2.0-2.4; P < .001). Finally, surveyed patients preferred TDRS to specialist exams (82.5%; 776/941) and would recommend the service to friends (92.7%; 868/936). CONCLUSION AND RELEVANCE: A statewide, FDSC-centered TDRS network was successfully established and sustained in a medically underserved region of the United States. Our results suggest that large TDRS networks in FDSCs can increase screening access and compliance for otherwise unscreened populations, but outcomes can vary greatly among clinics. Further work to optimize program implementation is needed to maximize this model's impact.

Diabetic neuropathy and other diabetic complications at the Diabetic Neuropathy Center of the University of Debrecen / A diabeteses neuropathia és egyéb szövodmények elofordulása a Debreceni Egyetem Diabeteses Neuropathia Centrumában

INTRODUCTION: The prevalence of diabetes mellitus is significantly increasing worldwide. Distal sensorimotor neuropathy (DSPN) is the most common and the earliest detectable microvascular complication. Due to its diverse clinical appearance and atypical symptoms, DSPN is often recognized in an advanced stage. AIM AND METHOD: In our study, the data of 431 patients who were examined using the Neurometer® between 2011 and 2018 at the Diabetic Neuropathy Center of the University of Debrecen were processed and the correlations between cardiovascular and microvascular complications, laboratory parameters and the severity of DSPN were investigated. RESULTS: The average age of patients was 63.4 years, 62% of them were women, and 92% had type 2 diabetes mellitus. The average duration of diabetes was 13.7 years. Cardiovascular disease (CVD) was diagnosed in 42% of the patients. The incidence of retinopathy was 12%, persistent microalbuminuria was 16%. Despite DSNP complaints, neuronal damage could not be detected in 19%; in the examined patients 49% had mild, 19% moderate and 13% severe neuropathy. Diabetes-related neurological damage was more serious in the presence of both diabetic retinopathy (p<0.001) and microalbuminuria (p<0.001). The incidence of these microvascular complications and the severity of DSPN showed a significant positive correlation (p<0.001). There was no correlation between the severity of peripheral neuropathy and the development of CVD, and we did not find any correlations between the severity of DSPN and CVD. CONCLUSION: Based on our investigation, correlation between the progression of diabetic neuropathy and cardiovascular complications was not found, although the progression of diabetic neuropathy indicated the development of other microvascular diseases. Peripheral neurological examination using the Neurometer® is appropriate for controlling the DSPN status and the establishment of the severity of neuropathy determines the quality of life in diabetic patients. Among these patients, the risk of CVD can be assessed by Ewing's test for autonomic nervous system function. Orv Hetil. 2020; 161(30): 1243-1251.

Factors Associated with Adherence to Screening Guidelines for Diabetic Retinopathy Among Low-Income Metropolitan Patients.

In this retrospective analysis of patients with diabetes in an academic primary care clinic in St. Louis, attendance at ophthalmic screening appointments was recorded over a two-year observation window. Factors associated with adherence were analyzed by multivariable regression. Among 974 total patients included, only 330 (33.9%) were adherent within a two-year period. Multivariate analyses identified older age, female gender, primary language other than English, and attendance at ancillary diabetes clinic visits as factors associated with improved diabetic retinopathy screening adherence. Factors not associated with adherence included race and insurance status.

Expectations and fears of patients with diabetes and macular edema treated by intravitreal injections.

AIMS: Clinical outcomes of diabetic macular edema (DME) have been widely described, but data on diabetic retinopathy perceptions by diabetes patients are limited. The aim of this survey was to explore the lived experience, knowledge, fears and expectations about disease, and treatment in patients with diabetes and macular edema treated with intravitreal injections (IVTI) and to characterize patient profiles. METHODS: Cross-sectional survey including a preliminary qualitative phase (20 patients with DME, treated or treatment-naive, 5 female and 15 male, age 36-74 years) followed by a quantitative survey (116 patients treated with IVTI for DME). Data ASKIA Analyze (version 5.3.3.5) was used for descriptive statistics, and R software (version 3.4.1) for multiple correspondence analysis. RESULTS: The qualitative phase identified the wording used by patients and information helpful to propose modalities of response in the quantitative phase. In the quantitative survey (116 patients, mean age 66.6 years), most patients were treated with anti-vascular endothelial growth factor. Overall, 71.9% reported that the disease negatively affected their daily activities and 33.1% considered that regular visits to the ophthalmologist were disrupting their life. Treatment expectations differed significantly between patients in terms of disease experience (visit and injection schedules), fears and feelings, and relationship with physicians, allowing three patient profiles to be identified: "Worried" patients (n = 45) felt isolated and were worried about the need for repeated treatment and possible side effects. They were mainly active men aged < 60 with type I diabetes (T1D) and DME diagnosed for > 2 years; "Curious" patients (n = 21) experienced insufficient support and requested more information on their disease and existing treatments. They were mainly single women aged 60-69 years; "Passive" patients (n = 50) felt sufficiently informed by their ophthalmologist and were not concerned by DME. They were older (mean age: 70 years) and mainly type 2 diabetic men. CONCLUSIONS: Patients with diabetes and macular edema treated with IVTI form a heterogeneous group regarding fears and expectations. Different patient profiles were identified and need to be confirmed in larger studies. A better understanding of psychological profiles may optimize compliance of diabetic patients.

Validation of a novel diabetic retinopathy utility index using discrete choice experiments.

BACKGROUND/AIMS: To validate a preference-based Diabetic Retinopathy Utility Index (DRU-I) using discrete choice experiment (DCE) methods and assess disutilities associated with vision-threatening DR (VTDR: severe non-proliferative DR, proliferative DR and clinically significant macular oedema) and associated vision impairment. METHODS: The DRU-I comprises five quality-of-life dimensions, including Visual symptoms, Activity limitation/mobility, Lighting and glare, Socio-emotional well-being and Inconvenience, each rated as no, some, or a lot of difficulty. The DRU-I was developed using a DCE comprising six blocks of nine choice sets which, alongside the EuroQoL-5D (EQ-5D-3L) and Vision and Quality of Life (VisQoL) utility instruments, were interviewer-administered to participants. To ensure the DRU-I was sensitive to severe disease, we oversampled patients with VTDR. Data were analysed using conditional logit regression. RESULTS: Of the 220 participants (mean±SD age 60.1±11.3 years; 70.9% men), 57 (29.1%) and 139 (70.9%) had non-VTDR and VTDR, respectively, while 157 (71.4%), 20 (9.4%) and 37 (17.3%) had no, mild or moderate/severe vision impairment, respectively. Regression coefficients for all dimensions were ordered as expected, with worsening levels in each dimension being less preferred (theoretical validity). DRU-I utilities decreased as DR severity (non-VTDR=0.87; VTDR=0.80; p=0.021) and better eye vision impairment (none=0.84; mild=0.78; moderate/severe=0.72; p=0.012) increased. DRU-I utilities had low (r=0.39) and moderate (r=0.58) correlation with EQ-5D and VisQoL utilities, respectively (convergent validity). DISCUSSION: The DRU-I can estimate utilities associated with vision-threatening DR and associated vision impairment. It has the potential to assess the cost-effectiveness of DR interventions from a patient perspective and inform policies on resource allocation relating to DR.

Psychological, social and everyday visual impact of diabetic macular oedema and diabetic retinopathy: a systematic review.

AIMS: To synthesize the evidence on the impact of diabetic retinopathy and diabetic macular oedema from the patient perspective. METHODS: A systematic literature review was conducted using MEDLINE Complete, PsycINFO, EMBASE and AMED. We included articles investigating the impact of the condition on quality of life, symptoms, visual functioning, activities of daily living, well-being, social functioning, and financial status. The studies evaluated were observational, including cross-sectional, prospective cohort and retrospective cohort designs. Outcome data were extracted and synthesized. RESULTS: Searches yielded 5114 publications. After screening, 85 studies were included, measuring the following outcomes: visual functioning (n=46); quality of life (n=22); well-being (n=16); functional status (n=5); work (n=4); and visual task performance (n=2). Diabetic retinopathy has a considerable impact on visual functioning and this is greater in people with greater disease severity. Diabetic retinopathy significantly limits activities including working, driving, walking and reading, and has the potential to have a negative impact on psychological well-being. CONCLUSIONS: Diabetic retinopathy is associated with poor self-reported visual functioning, well-being, and health-related quality of life. Ability to perform basic everyday tasks appears to diminish with disease severity. Some studies suggest impaired mobility and problems with work, but there are gaps in this evidence.

Identification and Evaluation of Items for Vitreoretinal Diseases Quality of Life Item Banks.

Purpose: We are developing item banks assessing the impact of retinal and vitreoretinal diseases (excluding age-related macular degeneration, diabetic retinopathy, and retinal detachment, covered elsewhere) on quality of life (QoL) for adults. This study outlines the first two phases of the multi-stage process: content development and item evaluation.Methods: We grouped retinal and vitreoretinal diseases into hereditary and acquired. Development of the item banks involved two phases: item identification and item evaluation. The items were extracted from three sources: (1) 17 pre-existing PRO instruments, (2) 4 qualitative studies and (3) 79 semi-structured interviews. Item evaluation involved three stages namely, binning (grouping) and winnowing (reduction), expert panel opinion and cognitive interviews.Results: The item identification phase yielded 1,217 items. After three sessions of binning and winnowing, items were reduced to a minimally representative set (n = 411) across nine QoL domains namely, activity limitation, emotional, social, health concerns, symptoms, economic, mobility, convenience, and coping. The hereditary group had a total of 345 items and the acquired group had a total of 257 items. After 23 cognitive interviews items were amended for hereditary diseases resulting in a final set of 345 items and 3 items were amended for acquired diseases, resulting in a final set of 254 items. Overall across nine domains 189 items were common to hereditary and acquired retinal and vitreoretinal diseases.Conclusion: As most of the items were unique to hereditary versus acquired retinal and vitreoretinal disease groups separate item banks are required to capture the QoL impacts for hereditary and acquired retinal and vitreoretinal diseases.

The Eysenck Personality Profile in Selected Groups of Ophthalmological Patients.

Personality correlates in patients with eye diseases have bidirectional influence. It is possible that personality variables lead to behaviours that may influence the cause of eye problems, but the opposite is also possible, that eye problems could have a direct effect on personality. The aim of this study was to evaluate personality traits in patients with glaucoma, diabetic retinopathy and cataract using the Eysenck Personality Questionnaire. Obtained results showed similar personality profiles in patients with glaucoma, diabetic retinopathy and cataract. However, extraversion and neuroticism were higher in patients with diabetes, while the psychopathic traits are the highest in the group of cataract. Age and gender of patients do not influence the scores obtained on the questionnaire confirmed with one way ANOVA. Not significant difference in parameters (tested with Student t-test) was obtained between groups. It is proposed psychological evaluation to be included in the assessment of more serious eye diseases for helping patients to adjust and adapt to the condition and treatment.

Quality of life in subjects with type 2 diabetes mellitus with diabetic retinopathy: A case-control study.

AIMS: Diabetic retinopathy (DR) as a common complication of Type 2 Diabetes Mellitus (T2DM) affecting negatively quality of life (QoL). Assessing of QoL in patients with DR is a prerequisite for the evaluation of their needs and for understanding the perception of the patients themselves about their health status and how the disease affects their lives. Additionally, QoL indicators detect individual psychosocial problems that may impact therapeutic response. MATERIALS AND METHODS: A total of 70 subjects with T2DM and DR as well as 70 T2DM individuals without DR were included. For the evaluation of QoL we used (a) WHO QoL - BREF for the estimation of QoL, (b) Life Satisfaction Scale for the estimation of satisfaction from life, and (c) the special recording document for demographic, socioeconomic, and clinical data. At the same time, blood was collected for the measurement of glucose control and renal function. DR was diagnosed by dilated fundoscopy. RESULTS: Patients with DR had significantly worse scores in all scales of QoL and Life Satisfaction in comparison with those without DR. We found significant impact of the severity of DR in many domains of the QoL and Life Satisfaction. Multivariate logistic regression analysis demonstrated that DR was associated with worse QoL and Life Satisfaction scores as well as lower income, while no significant associations were found with education level, family, insurance and employment status as well as type of residence. CONCLUSION: DR affects QoL and Life Satisfaction and is associated with lower income.
