RESUMO
PURPOSE: To compare three health-related quality of life (HRQoL) instruments in detecting the effect of distance visual acuity (VA) on generic HRQoL in an adult population. METHODS: We used cross-sectional, population-based data from a nationwide health survey conducted in Finland in 2011-2012. It included three self-reported HRQoL instruments, EuroQol-5 Dimension (EQ-5D), 15D, and EUROHIS-QOL8, and a health examination in which habitual distance VA was measured binocularly. We assessed 3764 survey participants aged 30 years and older with information available on these parameters. The comparability and sensitivity of the instruments were evaluated using Pearson correlation coefficients and multivariable linear regression in different VA groups. RESULTS: EQ-5D and 15D index scores showed strong positive correlation (0.65-0.74) with each other regardless of distance VA, whereas EUROHIS-QOL8 index score showed moderate-to-strong correlation (0.46-0.79) with EQ-5D and 15D. All three instruments showed a negative trend with deteriorating VA, although EQ-5D and 15D showed better sensitivity than EUROHIS-QOL8. When adjusted for age, gender, and co-morbidities, adequate vision (VA 0.63-0.8), weak vision (VA 0.32-0.5), and impaired vision or worse (VA ≤ 0.25) were independently associated with declined EQ-5D and 15D, whereas declined EUROHIS-QOL8 was associated only with adequate and weak vision. CONCLUSION: All three instruments can be viable tools in evaluating the relation between vision and HRQoL. While 15D is preferred due to its wide coverage of dimensions, EQ-5D can be an equal alternative, as it has less respondent burden. The feasibility of EUROHIS-QOL8 on detecting differences between lower VA levels may require further evidence.

PURPOSE: To study the prevalence and incidence of the most common eye diseases and their relation to health-related quality of life (HRQoL), depression, psychological distress, and visual impairment in the aging population of Finland. METHODS: Our study was based on two nationwide health surveys conducted in 2000 and 2011. Eye disease status data were obtained from 7379 and 5710 individuals aged 30 + years, of whom 4620 partook in both time points. Both surveys included identical indicators of HRQoL (EuroQol-5 Dimension [EQ-5D], 15D), depression (Beck Depression Inventory [BDI]), psychological distress (General Health Questionnaire-12 [GHQ-12]), visual acuity, and self-reported eye diseases. We assessed the impact of known eye diseases on these factors, adjusted for age, gender, and co-morbidities. RESULTS: Prevalence of self-reported eye diseases was 3.1/2.7% for glaucoma, 8.1/11.4% for cataract, and 3.4/3.8% for retinal degeneration in 2000 and 2011, and the average incidence between 2000 and 2011 was 22, 109, and 35 /year/10,000 individuals, respectively. These eye diseases were associated with a significant decrease in EQ-5D and 15D index scores in both time points. BDI and GHQ-12 scores were also worsened, with some variation between different eye diseases. Impaired vision was, however, the strongest determinant of declined HRQoL. During the 11-year follow-up the effect of eye diseases on HRQoL and mental health diminished. CONCLUSION: Declined HRQoL associated with eye diseases is more related to impaired vision than the awareness of the disease itself, and this declining effect diminished during the follow-up. Therefore, information directed to the public on the risks and prevention of blindness can and should be strengthened to prevent the deleterious effects of visual impairment.

The aim of the study was to provide an overview on the relation between vision and generic health-related quality of life (HRQoL) in general populations worldwide. We conducted a systematic review to identify articles that have evaluated the relation of binocularly measured distance visual acuity (VA) and HRQoL in adults at population level around the world. Used search terms were related to visual acuity, vision loss, visual impairment and HRQoL. We identified 780 articles, of which 12 satisfied the eligibility criteria. The studies were conducted in the USA, Europe, Asia and Australia. Generic HRQoL was measured using EQ-5D, 15D, SF-36, SF-12 and/or WHOQoL. Nine studies reported a trend between decreasing VA and deteriorating HRQoL of at least some degree. Vision loss was mostly associated with dimensions related to physical health and capability, including self-care, mobility and usual activities. Mental dimensions - vitality and social functioning in particular - were also affected, although the results were inconsistent. Six studies compared the impact of different medical conditions on HRQoL, all of which reported that the impact of visual impairment was equal or stronger compared with other major medical conditions. In conclusion, generic HRQoL instruments are sensitive to detect the relation between vision and HRQoL, as they cover dimensions influenced by vision. Declining vision is associated with reduced functioning, which leads to dependence and isolation - both major factors in an individual's well-being. This phenomenon showed surprising similarity around the world and therefore emphasises the global burden of vision loss at both individual and societal level and encourages its prevention and treatment.

PURPOSE: To evaluate time trends in distance and near vision at the national and regional levels during 2000-2017 in Finland. METHODS: We used three cross-sectional, nationwide health examination surveys representing the Finnish adult population aged 30 years or older in 2000, 2011 and 2017. Bilateral, habitual distance and near visual acuity (VA) were measured in all three surveys. RESULTS: The prevalence of good distance vision (VA ≥ 1.0) increased from 76.7% to 81.3% during 2000-2017 while the prevalence of weak or worse distance vision (VA ≤ 0.5) decreased from 7.6% to 3.7%. The improvements were largest among those aged 85 years and older: the prevalence of distance VA ≤ 0.5 decreased from 71.8% to 28.3%. Near vision showed improvement to a lesser extent in the total population; nevertheless, among those aged 85 years and older the prevalence of weak or worse near vision (VA ≤ 0.5) decreased from 62.3% to 27.1%. A similar positive time trend was observed in all main regions of Finland, and differences between urban and rural regions were small. CONCLUSION: During the past two decades, the overall vision level has improved among the adult population. This is explained mostly by a positive shift from lower to higher vision levels among older age groups, indicating that people live longer with good or adequate vision. This positive trend showed remarkable similarity throughout different regions in Finland, highlighting the importance of equal and accessible eye care throughout the country.
RESUMO
PURPOSE: To evaluate the changes in visual impairment (VI) due to age-related macular degeneration (AMD) during the past 40 years and the impact of novel therapies at population level. METHODS: In this nationwide register-based study, we assessed the incidence, prevalence, severity, and onset age of VI due to AMD based on the Finnish Register of Visual Impairment data from 1980 to 2019. Our data included 30 016 visually impaired persons with AMD as the main diagnosis for VI. The number of persons treated with intravitreal injections in Finland was obtained from hospital data kept by the Finnish Institute for Health and Welfare. RESULTS: Between the 1980s and the 2010s, the incidence of reported VI doubled; however, this increase has stagnated in the 2010s. Since 2012, the prevalence of reported VI has decreased. The number of patients treated with intravitreal injections showed a 40-fold increase during 2005-2019. The severity of reported VI has decreased whereas the mean age at the onset of reported VI has increased during the 40 years. The age-adjusted incidence and prevalence of reported VI were significantly higher in females in comparison to males in all decades. CONCLUSION: Increase in the incidence and prevalence of VI due to AMD in the past decades has stagnated and shifted to older age in the 2010s when therapies for exudative class became commonly available. Furthermore, the prognosis of VI has improved during the past 40 years. These positive trends are likely contributable to improved diagnostic tools, earlier diagnoses, and new therapy options.

BACKGROUND: The estimations of the economic burden of glaucoma have focused on comparing different treatment modalities; hence, the total direct and indirect costs of glaucoma at population level are not well known. OBJECTIVE: To estimate the direct and indirect costs of glaucoma and its treatment in Finland. METHODS: Economic and glaucoma data were collected from the cross-sectional nationwide Health 2000 health examination survey linked to multiple national registers, which allowed a 13-year follow-up between 1999-2011 among survey participants. Direct costs covered eye- and non-eye-related hospitalizations and outpatient visits, outpatient health care services, and travel costs among participants aged 30 years or older, adjusted for age and sex. Indirect costs covered premature retirement and productivity losses among participants aged 30-64 years. Glaucoma patients (n = 192) were compared with non-glaucomatous population (n = 6,952). RESULTS: The annual additional total direct costs were EUR 2,660/glaucoma patient, EUR 1,769/glaucoma patient with medication, and EUR 3,979/operated glaucoma patient compared with persons without glaucoma. The respective additional total indirect costs were EUR 4,288, EUR 3,246, and EUR 12,902 per year. In total, the additional annual direct and indirect expenditures associated with glaucoma in Finland were EUR 202 million (0.86% of total expenditures of health care) and EUR 71 million (0.03% of the Finnish gross domestic product) arising mainly from non-eye-related hospitalizations and productivity losses, respectively. CONCLUSION: Glaucoma is associated with an increased health care consumption mainly due to non-eye-related health care, which can be explained by the vision loss as well as increased number of co-morbidities among glaucoma patients. Therefore, glaucoma constitutes a major economic burden for the health care system and society, highlighting the importance of early glaucoma interventions. The difference in direct and indirect costs between glaucoma treatment groups is explained by the uneven distribution of co-morbidities.

PURPOSE: To evaluate the prevalence of ocular surface disease (OSD) signs and symptoms of glaucoma patients in private clinics in relation to topical glaucoma treatment and to compare them to non-glaucomatous population. METHODS: A multicenter, cross-sectional study consisting of private ophthalmology clinic visits in southern Finland. Glaucoma patients had a diagnosis of primary open-angle glaucoma, pseudoexfoliation glaucoma, pigmentary glaucoma, or treated ocular hypertension. Control patients had no prior or current use of glaucoma medication. Recorded parameters included OSD signs and symptoms, used glaucoma medications during the past 6 months, and the product name, type, and duration of used antiglaucoma drugs. RESULTS: Glaucoma patients (n = 564) showed higher severity of OSD sign parameters excluding Schirmer's test, as well as increased dry eye sensation compared to controls (n = 51). Beta-blockers and preservative-free prostaglandins had the smallest effect on all parameters. The increasing number of active compounds and administered eye drops per day showed an association with increasing severity of OSD signs, as well as dry eye and foreign body sensation. Duration of glaucoma medication showed no significant association with OSD signs or symptoms. CONCLUSION: Glaucoma patients show higher prevalence of OSD signs and dry eye sensation compared to non-glaucomatous population. The use of preserved glaucoma medication, as well as high number of active compounds and eye drops increase the severity of these parameters. There are significant differences between the types of glaucoma medication used, and therefore the selection of them is important especially in patients suffering from OSD.
RESUMO
PURPOSE: To report the incidence and severity of reported visual impairment (VI) due to glaucoma and the changes in them during the past 40 years in Finland. METHODS: A register-based study, in which the data were collected from the Finnish Register of Visual Impairment between 1980 and 2019. These data included 5819 visually impaired glaucoma patients, of which 61% were female. Visual impairment (VI) was classified according to the Finnish national definitions. The number of treated glaucoma patients in Finland was calculated using glaucoma medication reimbursement data available between 1986 and 2019 from the Social Insurance Institution of Finland registers. RESULTS: The incidence of reported VI due to glaucoma per 100 000 persons had increased from 2.3 in the 1980s to 3.4 in the 2010s. During the same time period, the incidence of reported VI per 10 000 treated glaucoma patients had decreased from 32 in the 1980s to 21 in the 2010s. Primary open-angle glaucoma (45%) was the main subtype for reported VI due to glaucoma. During the 40 years, the proportion of mild VI and the age at the onset of reported VI had increased. CONCLUSION: The incidence of reported VI due to glaucoma has increased during the 40 years, but the risk of treated glaucoma patients becoming visually impaired has decreased. Visual impairment (VI) also occurs at an older age. This is likely due to the earlier diagnoses and improved therapy. To prevent the unfavourable development of VI due to glaucoma among the ageing population in the future, all attempts need to be made to improve glaucoma care.

OBJECTIVE: To evaluate changes in the incidence, prevalence, severity, and onset age of visual impairment (VI) due to diabetic retinopathy (DR) and compare these trends in the screening and treatment of diabetes during 40 years based on Finnish national register data. RESEARCH DESIGN AND METHODS: We included people with VI with nonproliferative DR (NPDR; n = 2,490, 73% women) or proliferative DR (PDR; n = 2,026, 53% women) as the main diagnosis for VI during 1980-2019 in the Finnish Register of Visual Impairment. The number of patients with treated diabetes during 1986-2019 was obtained from the Social Insurance Institution of Finland registers based on reimbursed medication data. RESULTS: The annual incidence of reported VI due to DR has decreased since it peaked in the 1990s: regarding NPDR, it decreased from 102.3 to 5.5 per 100,000 patients with treated diabetes between the 1990s and 2010s; regarding PDR, the respective change was from 39.9 to 7.4. The incidence of patients with diabetes treated for DR increased during this period. Annual prevalence of reported VI and differences between sexes steadily decreased in the 2000s and 2010s. The severity of reported VI has decreased, and the age at the onset of reported VI increased during the 40 years. CONCLUSIONS: Prevalence and incidence of VI due to DR have dramatically decreased and shifted to older age during the 40 years despite the increasing prevalence of diabetes. These positive trends highlight the successful development and effectiveness of screening and therapies for diabetes and DR.

PURPOSE: To evaluate the impact of glaucoma on health-related quality of life (HRQoL) and mental health in the ageing population of Finland. METHODS: Altogether 7380 and 5774 Finnish individuals aged 30 years and older with known eye disease status were studied in 2000 and 2011, respectively, in two population-based surveys, including an 11-year follow-up of 4683 participants. Data on HRQoL (EQ-5D-3L, 15D), depression (BDI), psychological distress (GHQ-12) and eye disease diagnoses were obtained from self-reported assessments. Information on glaucoma was complemented with the medication, diagnosis and eye surgery data obtained from the Finnish Health Registries. Distance visual acuity was assessed using the Snellen eye chart test. In logistic regression analyses, data were corrected for age, gender and the most common comorbidities. RESULTS: Glaucoma patients with verified diagnosis (n = 192 in 2000, n = 202 in 2011) and individuals with self-suspected glaucoma (n = 100 in 2000, n = 41 in 2011) showed a significant decrease in their HRQoL. Glaucoma was also associated with worsened overall mental health based on BDI and GHQ-12 results. Visual impairment associated with glaucoma is the major determinant of the reduced HRQoL and mental health. Neither glaucoma medication nor glaucoma surgery affected these parameters. The impact of glaucoma on HRQoL and mental health diminished between 2000 and 2011 in a cross-sectional setting. The newly diagnosed glaucoma during the 11-year follow-up had a minimal effect on them. CONCLUSION: Glaucoma patients show reduced HRQoL and mental health, which is associated with vision loss regardless of the awareness or treatment of the disease. However, this effect seems to be diminishing over time, and the newly diagnosed glaucoma did not show a significant effect on either HRQoL or mental health.

Purpose: To assess the impact of cataract in ageing population by evaluating the prevalence, incidence, and background factors of cataract and cataract surgery. Patients and Methods: Two health examination surveys representing Finnish population in 2000 and 2011 included 7380 and 5930 participants aged 30 years or older with cataract status known. An 11-year follow-up included 4840 persons who participated in both the surveys. The data include information on physician-made diagnoses, socio-demographic factors, and lifestyle factors based on self-reported assessment. Cataract diagnoses and surgeries recorded in the Finnish Care Register for Health Care were linked to the survey data. Cataract patients were compared to those without cataract using logistic regression. Differences in cataract surgery age were evaluated using linear regression. Univariable and multivariable models were included. Results: During 2000-2011, the prevalence of cataract increased from 8.8% to 13.6% and cataract surgery from 5.7% to 8.9% in a representative sample of the Finnish adult population. Cataract and cataract surgery were associated with age, smoking, and high alcohol consumption. Cataract was also associated with female gender and low income in 2000, but this association declined during the 11 years. Smoking and high alcohol consumption were associated with younger surgery age. Conclusion: The prevalence of cataract and cataract surgery is increasing with the ageing of the population. The increase in cataract surgery is likely also reflecting the improvements in eye care. The possibility to equally use health-care services throughout a country can reduce the impact of socio-demographic status. Healthy lifestyle delays the development of cataract, whereas smoking and high alcohol consumption are associated with earlier cataract development. Therefore, the availability of cataract services and promotion of healthy lifestyle will be the key to prevent the detrimental effects of cataract on patients and the society in countries where the population is rapidly ageing.
