RESUMO
BACKGROUND: Epidemiological studies describe the distribution of glaucoma and its risk factors in the general population. MATERIAL AND METHODS: Epidemiological findings from population-based studies were extrapolated for the situation in Germany, in order to estimate current and future prevalence of glaucoma by using official population statistics for Germany. RESULTS: The prevalence of glaucoma in the adult population above 40 years of age is currently 2.1%, resulting in 980 thousand subjects with glaucoma, plus at least one more million subjects with ocular hypertension (OHT). Two thirds of all glaucoma cases are above 70 years of age. By 2060, the prevalence of glaucoma will increase to 2.8%, due to the aging of the population. CONCLUSIONS: Despite a decrease in the population size, glaucoma will become more prevalent in the future.

BACKGROUND: Retinal diseases such as neovascular age-related macular degeneration (nAMD), diabetic macular edema (DME), or branch/central retinal vein occlusion (B/CRVO) have significant implications for patients' social and psychological well-being. The ALBATROS study aimed to assess the care situation of patients who received anti-VEGF (vascular endothelial growth factor) treatment. To gain a comprehensive understanding of patients' backgrounds and attitudes, we developed an exploratory, structured questionnaire, the Basic Care and Patient Satisfaction Questionnaire (BPZ-9). METHODS: The data collection took place at the beginning and after twelve months of anti-VEGF therapy. The BPZ-9 questionnaire comprises nine questions to evaluate patients' psychological and social situation and satisfaction with treatment. RESULTS: Data were collected from 1478 nAMD (mean 78 years), 445 DME (67 years), 233 BRVO (70 years), and 144 CRVO (71 years) patients at 102 study centers throughout Germany. One in four patients had difficulties walking, and one in five needed an accompanying person for treatment. Anxiety about losing vision was present in three out of four patients at the beginning, and it slightly decreased to two out of three patients over the 12-month treatment period. The distress of having a retinal disease was generally higher than the distress related to the treatment. Most patients reported high treatment satisfaction (73%) and felt well-informed (81%). CONCLUSIONS: There is a relevant social and psychological impact related to anti-VEGF treatment. The patients' perception, attitudes, and commitment need further investigation.
RESUMO
BACKGROUND: Glaucoma is a widespread ophthalmological disease. Knowledge about the spread of the disease in the population is necessary with respect to further questions on comorbidities, risk factors and the provision of care. OBJECTIVE: An analysis of the use of glaucoma medications and the prevalence of glaucoma in an urban adult population was carried out. MATERIAL AND METHODS: The Hamburg City Health Study (HCHS) is a prospective, long-term, population-based cohort study that includes a random sample of 45,000 participants aged between 45 and 79 years from the general population of Hamburg, Germany. Apart from various medical parameters, data include premedication and the medical history of the participants. The use of antiglaucomatous medication among the first 10,000 study participants was analyzed and the prevalence of glaucoma was estimated according to the use of medications as well as by the self-reported history of glaucoma. Descriptive analysis and logistic regression analysis were performed to analyze the data and to calculate correlations by age and gender. RESULTS: In the study population 319 persons were on medication to lower the intraocular pressure (IOP, mean age 67.1 years, SDâ¯= 7.57 years), which is equivalent to an estimated prevalence of 3.35% (95% confidence interval, CI 3.00-3.70%). A positive correlation was observed between age and the use of IOP-lowering medication, which is statistically highly significant (pâ¯= <â¯0.001). The analysis by gender showed a slightly higher prevalence among women, which was not statistically significant. The estimated prevalence according to glaucoma medication and history were only partly congruent. DISCUSSION: This estimated prevalence of glaucoma is comparable to other epidemiological studies. The study results cover not only patients with manifest glaucoma but also persons who were treated for ocular hypertension. The inconsistency between the prevalence of glaucoma medication and the diagnosis of glaucoma can be explained by different treatment strategies and also by information deficits.

The use of OCT to monitor intravitreal treatment varies in clinical practice and is not always mandatory. The ALBATROS data collection aimed to clarify the impact of routinely implemented OCT on clinical outcomes and its impact on vision-related quality of life (VRQoL). METHODS: An observational cohort study included patients with retinal diseases starting an intravitreal anti-vascular endothelial growth factor treatment in Germany. Treatment followed clinical practice except mandatory OCT examination during the 12-month observation period. VRQoL was assessed by NEI VFQ-25 and compared with respect to OCT examinations and number of intravitreal injections in the different diseases (nAMD, DME, BRVO, CRVO). RESULTS: 1478 patients (74.5 ± 10.9 years, 54.9% female) were included in the analysis. Patients had neovascular AMD (65.2%), DME (18.4%), BRVO (9.5%), or CRVO (6.9%). 8.8 ± 2.6 OCT examinations and 6.1 ± 3.2 intravitreal injections were performed within 12 months. VRQoL differed between indications at baseline, with substantially lower values for neovascular AMD and CRVO. After twelve months, an increase in visual acuity and visual functional scale was observed for nAMD, DME, and BRVO, while in DME only, there was an association between number of OCT examinations and VRQoL. CONCLUSION: Intravitreal treatment was able to maintain VRQoL over twelve months in a real-world setting. Regular OCT examinations were associated with higher gain in VRQoL in DME patients after 12 months.
RESUMO
BACKGROUND: The options for glaucoma treatment are quite diverse. The question therefore arises what is considered beneficial and feasible in daily practice. Our anonymized survey among members of the German Ophthalmological Society (DOG) and the Professional Association of Ophthalmologists in Germany (BVA) intends to explore treatment patterns and strategies in routine glaucoma care in Germany. OBJECTIVE: The current article reflects current opinions of German ophthalmologists regarding glaucoma care, therapeutic strategies, and the role of glaucoma surgery. MATERIALS AND METHODS: The survey was conducted using an online questionnaire with 26 questions (107 items) regarding care practice for glaucoma diagnosis and treatment. Complete responses were available from 1361 participants. RESULTS: A total of 84.8% of responders define a target pressure regularly. A systemic therapeutic approach is followed by 44.9%. Two thirds consider side effects of eye drops to impair quality of life. Most common are conjunctival hyperemia and burning. Non-adherence to treatment is estimated to occur in 32% of patients. Approximately 5-10% of glaucoma patients are treated surgically. Among interventional treatment options, 90% consider trabeculectomy beneficial, followed by minimally invasive glaucoma surgery (MIGS) and selective laser trabeculoplasty (SLT), which are, however, the most commonly performed procedures. CONCLUSION: The choice of treatment should intend a long-lasting reduction of intraocular pressure and yet to be reasonable and manageable. There is a demand for more overview and structured care.

OBJECTIVES: In order to better understand the continued barriers to the provision of vascular endothelial inhibitor therapy, this study aims to investigate patients' experiences with neovascular age-related macular degeneration (nvAMD) in Germany during the injection process and how they deal with it. DESIGN AND PARTICIPANTS: This analysis is part of the qualitative arm of a wider mixed-methods study. We recruited participants all over Germany via ophthalmologists, eye clinics, general practitioners, care bases and support groups between June 2018 and December 2020 and selected a subsample of study participants with nvAMD who were either undergoing or had previously undergone vascular endothelial growth factor inhibitor therapy. We conducted narrative, semistructured, face-to-face interviews at the participants' homes, which were audio-recorded. The interviews were thematically analysed. RESULTS: Twenty-two participants were included in this analysis. Experiencing neovascular macular degeneration was dominated by the injection experience. Study participants perceived the treatment with vascular endothelial inhibitor injections as uncomfortable, and they described undergoing varying levels of anxiety during the whole injection process. After some years of receiving multiple injections, the pain and not experiencing any positive effects made participants with significant vision loss want to discontinue therapy. Furthermore, they narrated negative injection experiences in association with their interactions with medical staff and doctors. CONCLUSION: Although time in the medical setting is limited, efficient and good doctor-patient relationships seem crucial for satisfying care experiences. A respectful and humane relationship may be one key to achieving treatment adherence.

BACKGROUND: Intravitreal drug delivery belongs to the most common medical procedures, with approximately 1.5 million treatments per year in Germany. However, for this enormous challenge to provision of proper care, there is a lack of empirical data regarding the treatment process and its clinical and subjective effect. MATERIALS AND METHODS: This publication presents the development and structure of the Hamburg register for intravitreal therapies (QIVOM). Patients undergoing intravitreal injection therapy were invited to join the register study. Patients were recruited from the Hamburg eye clinics in Heidberg-Nord and Barmbek as well as from the University Medical Center Hamburg-Eppendorf (UKE). Both subjective patient-reported information about the perception of their eye disease and its treatment as well as medical parameters were stored in a central electronic database. RESULTS: Of the first 162 study patients (aged 41-95 years), 64% suffered from wet age-related macular degeneration (AMD), 22% had a retinal vein occlusion, and 11% a diabetic macula edema. Disease severity and subjective impairment were heterogenous. Among these patients, 31.8% had a visual acuity above 10/20 on the treated eye compared to 79.1% on the other eye. The reduced ability to read was the most relevant limitation for more than one third of patients. However, 62% were able to drive a vehicle. An improvement of vision through intravitreal therapy was experienced by 45%. CONCLUSION: Collection of patient-reported as well as treatment-related data comprises the advantage of the newly created register. This extension of the data basis should deliver new findings in the future and contribute to quality assurance in intravitreal care.

BACKGROUND: Glaucoma care has extended enormously in recent years. We performed a survey among the members of the German Ophthalmological Society (DOG) and the Professional Association of Ophthalmologists in Germany (BVA) to explore treatment patterns, the importance of different diagnostic parameters as well as treatment guidelines in the daily practice of glaucoma care. OBJECTIVE: Assessment of the current practice of glaucoma care among German ophthalmologists, evaluation of key diagnostic parameters and their use in daily practice. MATERIAL AND METHODS: Our survey was conducted using an online questionnaire that consisted of 26 questions (107 items) about the treatment practice for the diagnosis and treatment of glaucoma. Complete responses were available from 1361 participants. RESULTS: Slit-lamp examination still remains the most important tool for diagnosis in glaucoma. A very high ranking was also achieved for optical coherence tomography (OCT) parameters. With respect to clinical interpretation and diagnostic certainty parameters analyzing the optic disc were ranked higher than others. Guideline-oriented care is being practiced by the vast majority of ophthalmologists according to self-reported results-two thirds perform perimetry two or more times and a structural analysis once in the first year after diagnosis. The importance of gonioscopy is controversial among the survey participants and is therefore being practiced with different intensity. DISCUSSION: The diagnosis of glaucoma is challenging. Different diagnostic parameters are of different values to the ophthalmologists. Morphometric tools have achieved a highly important role for the diagnosis of glaucoma and enable assisted, yet not automated diagnosis. Treatment guidelines and standards are requested and should be implemented in education and care practice.

Objectives: Little is known about the specific association of vision loss and psychosocial outcome measures in contrast to other health limitations. The aim of this study was to identify whether vision problems are associated with psychosocial outcomes among middle-aged and older adults and to compare it with the association between other chronic health conditions and psychosocial factors.Method: Cross-sectional data came from wave 5 (2014) of the German Ageing Survey which is a representative sample of non-institutionalized individuals ≥ 40 years in Germany. Psychosocial outcomes (life satisfaction, positive affect, negative affect, depressive symptoms, optimism, general self-esteem, and social isolation) were assessed using well-established and widely used scales. Self-rated trouble reading the newspaper due to vision problems and self-rated difficulties recognizing known people on the street due to vision problems were used as independent variables of interest.Results: Regressions showed that both 'vision problems: reading the newspaper' and 'vision problems: difficulties recognizing people' are consistently associated with worse psychosocial outcomes (decreased life satisfaction, decreased positive affect, increased negative affect, increased depressive symptoms, decreased optimism, decreased self-esteem and increased social isolation). In contrast, none of the physical illnesses was consistently associated with all psychosocial outcome measures.Conclusion: Adjusting for various potential confounders and in contrast to various chronic diseases, our findings emphasize an association between vision problems and worse psychosocial outcomes in middle-aged and older adults. Future longitudinal studies are needed to validate our findings.

BACKGROUND: The distribution of visual impairment is an indicator of the health status of the population and for the frequency of diseases of the eye. METHODS: The Gutenberg Health Study (GHS) is a population-based cohort study in Germany concerning adults aged 35 to 74. 15 010 subjects from the Mainz-Bingen region underwent general medical and ophthalmological examination, with measurement of the distance-corrected visual acuity in each eye separately. As per the World Health Organization criteria, visual impairment was defined as an acuity below 0.3 in the better eye, and blindness as an acuity below 0.05. All patients who were found to be visually impaired or blind underwent further individual study with clinical history-taking, split-lamp examination, and fundus photography. RESULTS: Data from 14 687 subjects were evaluated. The mean age of the partici- pants was 55.0 years (standard deviation, 11.1 years). The prevalence of visual im- pairment was 0.37% (95% confidence interval [0.28; 0.49]) (n = 55) and was higher in women (0.44%) than in men (0.31%). Blindness was present in 0.05% [0.03; 0.11] (n = 8) of the subjects. The prevalence of visual impairment from age 65 on- ward was 0.79%, three times higher than in the younger age groups. 54.5% of the visually impaired subjects had multiple underlying ophthalmological pathologies. CONCLUSION: The causes of visual impairment are manifold. Loss of vision is often the combined effect of multiple pathological factors. The etiology of visual impair- ment is thus a more complex matter than is commonly assumed.

PURPOSE: Most definitions of visual impairment focus on the status of the better-seeing eye only, but this approach might underestimate the influence of the worse-seeing eye on the vision-related quality of life (VRQoL). METHODS: We assessed distance-corrected visual acuity in both eyes and VRQoL using the "National Eye Institute 25-Item Visual Function Questionnaire" (NEI VFQ-25) in the German population-based Gutenberg Health Study. We calculated the Rasch-based visual functioning scale (VFS) and socioemotional scale (SES). We categorized the visual acuity of the better-seeing eye (BE) and worse-seeing eye (WE) as follows: (1) no visual impairment (VI) (< 0.32 logMAR)), (2) mild VI (0.32-0.5 logMAR), and (3) moderate to severe VI (> 0.5 logMAR). Next, the subjects were categorized as follows: both eyes with no VI (no/no), the better-seeing eye with no VI and the worse-seeing eye with mild VI (no/mild), no VI/severe VI (no/severe), both eyes with mild VI (mild/mild), light VI/severe VI (mild/severe), and both eyes with severe VI (severe/severe). We calculated the median scores for VFS and SES. We used linear regression to estimate the combined influence of BE/WE on VFS and SES. RESULTS: We included 11,941 participants (49.9% female, age range: 35-74 years) with information on VRQoL and visual acuity. The median VFS/SES scores were 90/100 (no/no VI group), 84/97 (no/mild group), 81/94 (no/severe group), 70/90 (mild/mild group), 67/74 (mild/severe group), and 63/76 (severe/severe group). These differences were supported by the regression analysis results. CONCLUSION: Relying on the function of the better-seeing eye considerably underestimates the impact of visual impairment on VRQoL.

The needs-based provision of medical services to the population represents a challenge for ophthalmology, not least as eye diseases become more frequent with age. Age-related macular degeneration, glaucoma, diabetic retinopathy and cataract occur particularly often. So far only few current population-based data have been available in Germany; however, this is currently changing with several ongoing population-based cohort studies, such as the Gutenberg Health Study, the National Cohort and the Rhineland Study. Preliminary data from the Gutenberg Health Study show that the expected increase in the prevalence of eye diseases with ageing has occurred and the development is comparable with international data from industrial countries. Over the last 15 years age-related eye diseases have increased by 15-34% due to demographic changes. The number of ophthalmologists increased during this period by 19%; however, as an ever increasing proportion do not work full time, the treatment time in ophthalmology only increased by 1%. Particularly in the working relationship of private practice employees, more ophthalmologists are now working than 15 years ago, the majority in part-time employment, whereas the number of self-employed ophthalmologists has declined. For ophthalmological care planning it is important to consider not only the age-related increase in patients but also the changes in treatment capacity, which cannot be solely derived from the absolute number of actively involved ophthalmologists.

Purpose: Effective glaucoma therapy relies to a great extent on the patients' ability to regularly self-administer eye drops. This study aimed to assess self-reported nonadherence and to identify potential barriers to adherence in glaucoma patients. Methods: Participants completed a 16-item questionnaire, designed to examine nonadherence rate and assess the therapy experience. Inclusion criteria stipulated treatment duration of at least 1 year. Nonadherence was defined as missing ≥5% of the prescribed pressure-lowering eye drops doses. Results: In total, 201 glaucoma patients aged 24-88 years were included. Mean treatment duration was 9.4 years. Nonadherence was reported by 30.3% of participants and 69.7% were reported to be adherent. Individuals who experienced side effects reported higher levels of nonadherence than those who did not (37.6% vs. 18.4%; P = 0.004). Eye drops with preservatives were used by 84.1% of participants, 11.9% were on combined preservative and preservative-free treatment, and 4.0% on preservative-free medication only. Self-reported nonadherence levels were 32.0%, 25.0%, and 12.5%, respectively, for each of these groups. Men reported higher rates of nonadherence than women (36.8% vs. 24.5%; P = 0.066). Age, social status, history of migration, severity of disease, and fear of blindness were not associated with significant differences in nonadherence levels. Conclusions: Nonadherence with glaucoma therapy is a significant barrier to therapeutic success for approximately one-third of patients. Nonadherence may be reduced if side effects are avoided. Preservative-free products may provide adherence benefits. The patient experience should be a key consideration when selecting appropriate treatments, to reduce nonadherence and optimize outcomes.

TOPIC: To estimate the prevalence of nonrefractive visual impairment and blindness in European persons 55 years of age and older. CLINICAL RELEVANCE: Few visual impairment and blindness prevalence estimates are available for the European population. In addition, many of the data collected in European population-based studies currently are unpublished and have not been included in previous estimates. METHODS: Fourteen European population-based studies participating in the European Eye Epidemiology Consortium (n = 70 723) were included. Each study provided nonrefractive visual impairment and blindness prevalence estimates stratified by age (10-year strata) and gender. Nonrefractive visual impairment and blindness were defined as best-corrected visual acuity worse than 20/60 and 20/400 in the better eye, respectively. Using random effects meta-analysis, prevalence rates were estimated according to age, gender, geographical area, and period (1991-2006 and 2007-2012). Because no data were available for Central and Eastern Europe, population projections for numbers of affected people were estimated using Eurostat population estimates for European high-income countries in 2000 and 2010. RESULTS: The age-standardized prevalence of nonrefractive visual impairment in people 55 years of age or older decreased from 2.22% (95% confidence interval [CI], 1.34-3.10) from 1991 through 2006 to 0.92% (95% CI, 0.42-1.42) from 2007 through 2012. It strongly increased with age in both periods (up to 15.69% and 4.39% in participants 85 years of age or older from 1991 through 2006 and from 2007 through 2012, respectively). Age-standardized prevalence of visual impairment tended to be higher in women than men from 1991 through 2006 (2.67% vs. 1.88%), but not from 2007 through 2012 (0.87% vs. 0.88%). No differences were observed between northern, western, and southern regions of Europe. The projected numbers of affected older inhabitants in European high-income countries decreased from 2.5 million affected individuals in 2000 to 1.2 million in 2010. Of those, 584 000 were blind in 2000, in comparison with 170 000 who were blind in 2010. CONCLUSIONS: Despite the increase in the European older population, our study indicated that the number of visually impaired people has decreased in European high-income countries in the last 20 years. This may be the result of major improvements in eye care and prevention, the decreasing prevalence of eye diseases, or both.

PURPOSE: To investigate whether myopia is becoming more common across Europe and explore whether increasing education levels, an important environmental risk factor for myopia, might explain any temporal trend. DESIGN: Meta-analysis of population-based, cross-sectional studies from the European Eye Epidemiology (E(3)) Consortium. PARTICIPANTS: The E(3) Consortium is a collaborative network of epidemiological studies of common eye diseases in adults across Europe. Refractive data were available for 61 946 participants from 15 population-based studies performed between 1990 and 2013; participants had a range of median ages from 44 to 78 years. METHODS: Noncycloplegic refraction, year of birth, and highest educational level achieved were obtained for all participants. Myopia was defined as a mean spherical equivalent ≤-0.75 diopters. A random-effects meta-analysis of age-specific myopia prevalence was performed, with sequential analyses stratified by year of birth and highest level of educational attainment. MAIN OUTCOME MEASURES: Variation in age-specific myopia prevalence for differing years of birth and educational level. RESULTS: There was a significant cohort effect for increasing myopia prevalence across more recent birth decades; age-standardized myopia prevalence increased from 17.8% (95% confidence interval [CI], 17.6-18.1) to 23.5% (95% CI, 23.2-23.7) in those born between 1910 and 1939 compared with 1940 and 1979 (P = 0.03). Education was significantly associated with myopia; for those completing primary, secondary, and higher education, the age-standardized prevalences were 25.4% (CI, 25.0-25.8), 29.1% (CI, 28.8-29.5), and 36.6% (CI, 36.1-37.2), respectively. Although more recent birth cohorts were more educated, this did not fully explain the cohort effect. Compared with the reference risk of participants born in the 1920s with only primary education, higher education or being born in the 1960s doubled the myopia prevalence ratio-2.43 (CI, 1.26-4.17) and 2.62 (CI, 1.31-5.00), respectively-whereas individuals born in the 1960s and completing higher education had approximately 4 times the reference risk: a prevalence ratio of 3.76 (CI, 2.21-6.57). CONCLUSIONS: Myopia is becoming more common in Europe; although education levels have increased and are associated with myopia, higher education seems to be an additive rather than explanatory factor. Increasing levels of myopia carry significant clinical and economic implications, with more people at risk of the sight-threatening complications associated with high myopia.

To estimate the prevalence of refractive error in adults across Europe. Refractive data (mean spherical equivalent) collected between 1990 and 2013 from fifteen population-based cohort and cross-sectional studies of the European Eye Epidemiology (E(3)) Consortium were combined in a random effects meta-analysis stratified by 5-year age intervals and gender. Participants were excluded if they were identified as having had cataract surgery, retinal detachment, refractive surgery or other factors that might influence refraction. Estimates of refractive error prevalence were obtained including the following classifications: myopia ≤-0.75 diopters (D), high myopia ≤-6D, hyperopia ≥1D and astigmatism ≥1D. Meta-analysis of refractive error was performed for 61,946 individuals from fifteen studies with median age ranging from 44 to 81 and minimal ethnic variation (98 % European ancestry). The age-standardised prevalences (using the 2010 European Standard Population, limited to those ≥25 and <90 years old) were: myopia 30.6 % [95 % confidence interval (CI) 30.4-30.9], high myopia 2.7 % (95 % CI 2.69-2.73), hyperopia 25.2 % (95 % CI 25.0-25.4) and astigmatism 23.9 % (95 % CI 23.7-24.1). Age-specific estimates revealed a high prevalence of myopia in younger participants [47.2 % (CI 41.8-52.5) in 25-29 years-olds]. Refractive error affects just over a half of European adults. The greatest burden of refractive error is due to myopia, with high prevalence rates in young adults. Using the 2010 European population estimates, we estimate there are 227.2 million people with myopia across Europe.

OBJECTIVE: To study the distribution of refractive errors among adults of European descent. DESIGN: Population-based eye study in Germany with 15010 participants aged 35-74 years. METHODS: The study participants underwent a detailed ophthalmic examination according to a standardised protocol. Refractive error was determined by an automatic refraction device (Humphrey HARK 599) without cycloplegia. Definitions for the analysis were myopia <-0.5 dioptres (D), hyperopia >+0.5 D, astigmatism >0.5 cylinder D and anisometropia >1.0 D difference in the spherical equivalent between the eyes. Exclusion criterion was previous cataract or refractive surgery. RESULTS: 13959 subjects were eligible. Refractive errors ranged from -21.5 to +13.88 D. Myopia was present in 35.1% of this study sample, hyperopia in 31.8%, astigmatism in 32.3% and anisometropia in 13.5%. The prevalence of myopia decreased, while the prevalence of hyperopia, astigmatism and anisometropia increased with age. 3.5% of the study sample had no refractive correction for their ametropia. CONCLUSIONS: Refractive errors affect the majority of the population. The Gutenberg Health Study sample contains more myopes than other study cohorts in adult populations. Our findings do not support the hypothesis of a generally lower prevalence of myopia among adults in Europe as compared with East Asia.

BACKGROUND: The aim of this study was to describe the sex- and age-specific prevalence of age-related macular degeneration (AMD) and its correlation with urban or rural residence in a large and relatively young European cohort. METHODS: We evaluated fundus photographs from participants in the Gutenberg Health Study (GHS), a population-based, prospective, observational, single-centre study in the Rhineland-Palatine region in midwestern Germany. The participants were 35-74 years of age at enrolment. The fundus images were classified as described in the Rotterdam Study and were graded independently by two experienced ophthalmologists (CK and UBK) based on the presence of hard and soft drusen, retinal pigmentary abnormalities, and signs of atrophic or neovascular age-related macular generation (AMD). RESULTS: Photographs from 4,340 participants were available for grading. Small, hard drusen (<63 µm, stages 0b and 0c) were present in 37.4% of participants (95% confidence interval [CI], stage 0b, 31.6% [30.3-33.7]; stage 0c, 5.8% [5.1-6.5]). Early AMD (soft drusen, pigmentary abnormalities, stages 1-3) was present in 3.8% of individuals in the youngest age group (35-44 years) (95% CI, stage 1a, 0.4% [0.3-0.5%]; stage 1b, 3.2% [2.9-3.5%]; stage 2a, 0.1% [0.1-0.2%]; stage 2b, 0% [0-0.0%]; stage 3, 0.1% [0.1-0.2%]), whereas late AMD (stages 4a and 4b) did not appear in the youngest age group. In all age groups, signs of early AMD were detected in 11.9% of individuals (stage 1a, 2.1% [1.7-2.6]; stage 1b, 8.0% [7.2-8.8]; stage 2a, 1.0% [0.7-1.3]; stage 2b, 0.5% [0.3-0.7]; stage 3, 0.3% [0.2-0.6]). Late AMD (geographic atrophy or neovascular AMD) was found in 0.2% of individuals (stage 4a, 0.1 % [0.0-0.2]; stage 4b, 0.1% [0.0-0.2]). AMD increased significantly with age (odds ratio [OR], 1.09; 95% CI, 1.08-1.10). Sex, iris colour, and residence (rural vs. urban) were not associated with different rates of AMD. CONCLUSIONS: In this study, the prevalence of AMD increased dramatically with age; however, although AMD is usually thought to occur after age 50, signs of early AMD were found in 3.8% of individuals in the youngest age group (younger than 45 years). This population-based sample is the first to provide substantial epidemiologic data from a large German cohort, including data on macular degeneration in younger age groups and incidence data after recall.

PURPOSE: To identify and describe the most relevant obstacles to carrying out ophthalmic research in Germany. METHODS: Two research methods were used to assess current problems in ophthalmic research. First, 55 expert interviews were conducted with major stakeholders in ophthalmic research, and key problems were identified. An online questionnaire was then sent to 3,080 German ophthalmologists, of whom 927 responded by evaluating the current research situation within ophthalmology in Germany. We devised a score to rank areas of concern by multiplying the responders' rate, ranging between -3 ('I disagree completely') and +3 ('I fully agree'), with the percentage of response frequencies. The maximum possible score was 300. RESULTS: The lack of opportunities to combine clinical work and research (score: 231.8) as well as unattractive career perspectives (175.7) were identified as the most relevant problems. Further barriers were difficulties in acquiring research funds (155.7), organizational problems at the local level (143.7) and a lack of support for women (24.1; among women: 122.3). Potential improvement was expected in particular from exemption from clinical work for scientific purposes; this was found to be more appealing than more prestigious awards for research achievements. A widely held position was that research projects should focus more closely on common eye diseases, and that vision research needs a more prominent profile among politicians and in the public arena. CONCLUSION: Our findings may help to initiate improvements in both research performance and outcomes.

MAIN OBJECTIVE: To evaluate the distribution of central corneal thickness (CCT) in a large German cohort and to analyse its relationship with intraocular pressure and further ocular factors. DESIGN: Population-based, prospective, cohort study. METHODS: The Gutenberg Health Study (GHS) cohort included 4,698 eligible enrollees of 5,000 subjects (age range 35-74 years) who participated in the survey from 2007 to 2008. All participants underwent an ophthalmological examination including slitlamp biomicroscopy, intraocular pressure measurement, central corneal thickness measurement, fundus examination, and were given a questionnaire regarding glaucoma history. Furthermore, all subjects underwent fundus photography and visual field testing using frequency doubling perimetry. RESULTS: Mean CCT was 557.3 ± 34.3 µm (male) and 551.6±35.2 µm in female subjects (Mean CCT from right and left eyes). Younger male participants (35-44 years) presented slightly thicker CCT than those older. We noted a significant CCT difference of 4 µm between right and left eyes, but a high correlation between eyes (Wilcoxon test for related samples: p<0.0001). Univariable linear regression stratified by gender showed that IOP was correlated with CCT (p<0.0001). A 10 µm increase in CCT led to an increase in IOP between 0.35-0.38 mm Hg, depending on the eye and gender. Multivariable linear regression analysis revealed correlations between gender, spherical equivalent (right eyes), and CCT (p<.0001 and p=0.03, respectively). CONCLUSIONS: We observed positive correlations between CCT and IOP and gender. CCT was not correlated with age, contact lens wear, positive family history for glaucoma, lens status, or iris colour.
