[Macular hole: Differential diagnosis, treatment options and new guideline recommendations]. / Makulaforamen: Differenzialdiagnose, Behandlungsoptionen und neue Leitlinienempfehlungen.

Full-thickness macular holes (FTMH) usually result in a pronounced reduction of visual acuity and represent one of the most frequent indications for retinal surgery. If diagnosed and treatment is initiated at an early stage, surgery has a high success rate with respect to both hole closure and improvement of visual acuity. Optical coherence tomography (OCT)-based staging and sizing enables an estimation of the surgical outcome. The differential diagnostic distinction from clinically similar disorders, such as lamellar macular holes, macular pseudoholes, and foveoschisis is clinically relevant as the pathogenesis, prognosis and treatment are significantly different. While vitrectomy with peeling of the inner limiting membrane (ILM) and gas tamponade is established as the standard treatment for FTMH, some aspects of treatment are handled differently between surgeons, such as the timing of surgery, the choice of endotamponade and the type and duration of postoperative positioning. For FTMH associated with vitreomacular traction, alternative treatment options in addition to vitrectomy include intravitreal ocriplasmin injection and pneumatic vitreolysis. The current clinical guidelines of the German ophthalmological societies summarize the evidence-based recommendations for diagnosis and treatment of FTMH.

Retinopathy of prematurity in Germany over 13 years: incidences, treatment preferences and effects of national guideline changes.

OBJECTIVE: Retinopathy of prematurity (ROP) is a leading yet avoidable cause of childhood blindness. Screening for ROP is highly effective in preventing blindness secondary to ROP. We provide epidemiological data on ROP screening and treatment in Germany since 2010 and evaluate the effects of recently adopted as well as potential future screening guideline adaptations. METHODS: Data sets of the German Quality Assurance Procedure in Neonatology, the ROP screening programme of two German university hospitals, and the German section of the EU-ROP Registry were analysed. RESULTS: Over the 13-year period from 2010 to 2022, 141 550 infants received ROP screening in Germany. Mean annual incidences of ROP were 3.5% (±0.2%) in premature infants and 19.6% (±2.3%) in screened infants. Of screened infants, 2.0% (±0.3%) received treatment for ROP. Treatment preferences shifted from laser coagulation (46.2% in 2015) to anti-vascular endothelial growth factor therapy (83.7% in 2022). A revision of national screening criteria in 2020 with a reduction of the gestational age limit from <32 to <31 weeks resulted in a decrease of the annual number of infants requiring screening by 25.8% (p<0.001). Infants with a birth weight ≥1500 g accounted for 35.2% of the screening population but only for 0.4% of ROP stage 3-5 cases. CONCLUSIONS: Collection of epidemiological data on ROP in national and international registries enables the continuous surveillance and adaptation of ROP screening and treatment criteria. In Germany, infants with a birth weight ≥1500 g have a very low risk of developing treatment-requiring ROP, supporting an upper birth weight limit for ROP screening.

Piloting Rasch model scoring of the National Eye Institute Visual Function Questionnaire in uveitis.

INTRODUCTION: The National Eye Institute Visual Function Questionnaire (NEI VFQ) is a common patient-reported outcome measure (PROM) in uveitis trials. Its psychometric properties using state-of-the-art scoring based on Rasch models, a latent trait model that improves accuracy of PROMs assessment, has not yet been investigated. METHODS: The study participants were recruited online from uveitis patient organizations, where individuals self-reported their uveitis diagnosis and visual acuity level. These participants then completed the NEI VFQ-25. The visual function (VF) and socioemotional (SE) subscales were psychometrically analysed in terms of item fit, targeting, internal consistency, dimensionality, and differential item functioning (DIF), using Rasch models. Criterion validity was examined based on associations between NEI VFQ person measures and recent visual acuity (VA) levels. RESULTS: Ninety-nine participants recruited online from uveitis patient organizations (68 women, 31 men; mean age 50 ± 15 years; 46.5% self-reported receiving systematic therapy for uveitis, 0.6% NEI VFQ-25 missing data) were included. The mean difficulty of items was lower than the average person ability. None of the items demonstrated misfit to an extent that would induce noise into the measurement. The consistency metrics person reliability and person separation index of the subscales were 0.85 and 2.34 (NEI VFQ-VF), 0.86 and 2.52 (NEI VFQ-SE), respectively. There was no evidence of multidimensionality and none of the items showed DIF by gender. The differences between item and person measures were 1.44 (NEI VFQ-VF) and 1.03 (NEI VFQ-SE). NEI VFQ-25 person measures were significantly lower in participants with visual impairment (all p values ≤ 0.007). CONCLUSION: Rasch model-based scoring of the re-engineered NEI VFQ-25 demonstrates acceptable internal consistency, item fit and construct validity for assessing two key domains of quality of life in individuals self-reporting uveitis. The PROM was targeted at a higher level of difficulty than present in our heterogeneous sample.

Outcomes of short- versus long-acting gas tamponades in vitrectomy for rhegmatogenous retinal detachment.

BACKGROUND: In vitrectomy for rhegmatogenous retinal detachment, long-acting gas tamponades (LGT) such as C3F8 or C2F6 may improve surgical success rate due to their prolonged effect compared to a short-acting gas tamponade (SGT) with SF6. On the other hand, SGT allow a significantly faster visual rehabilitation after surgery and may reduce the risk of gas-related complications. As comparative data in retinal detachment surgery is limited, we assessed the outcomes of vitrectomies using either LGT or SGT. METHODS: We retrospectively analyzed 533 eyes of 524 consecutive patients diagnosed with primary rhegmatogenous retinal detachment not complicated by proliferative vitreoretinopathy (PVR) and treated by vitrectomy at two clinical sites. Depending on the site the patients presented at, they received either preferentially LGT (study site 1) or SGT (study site 2). Retinal re-detachment rates during a period of 6 months following surgery were analyzed. RESULTS: At study site 1, 254 of 278 eyes (91.4%) were treated by LGT (C3F8 72.3%; C2F6 19.1%), whereas at study site 2, 246 of 255 eyes (96.5%) received SGT (SF6). Rates of retinal re-detachment in the LGT- and SGT-treated groups were similar with 23 of 254 eyes (9.1%) and 24 of 246 eyes (9.8%), respectively (p = 0.9). Median time to re-detachment was 5.7 weeks in the LGT-treated group and 4.4 weeks in the SGT-treated group (p = 0.4). CONCLUSION: In rhegmatogenous retinal detachment repair by vitrectomy, the use of SGT results in comparable rates of successful retinal re-attachment as LGT. Given the faster visual rehabilitation with SGT, these results suggest SGT as a sensible alternative to LGT in surgery of retinal detachment without PVR.

[Late sequelae of retinopathy of prematurity in infancy]. / Spätfolgen der Frühgeborenenretinopathie im Kindesalter.

BACKGROUND: Retinopathy of prematurity (ROP) is one of the most frequent causes of severe visual impairment or blindness in childhood and can lead to severe late complications in children even after the initial disease has resolved. PURPOSE: The present study summarizes possible late effects in childhood after treated and untreated ROP. A special focus is on the development of myopia, retinal detachment, as well as neurological and pulmonary development after anti-vascular endothelial growth factor (VEGF) treatment. MATERIAL AND METHODS: This work is based on a selective literature search on late effects in childhood of treated or untreated ROP. RESULTS: Preterm infants have an increased risk of developing high-grade myopia. Interestingly, several studies indicate that the risk of myopia is reduced following anti-VEGF treatment. With anti-VEGF treatment, however, late recurrences after initial response are possible even after several months, making long-term and frequent follow-up examinations essential. Controversy exists regarding the possible negative effects of anti-VEGF treatment on neurological and pulmonary development. After both treated and untreated ROP, rhegmatogenous, tractional or exudative retinal detachment, vitreous hemorrhage, high myopia and strabismus are possible late complications. DISCUSSION: Children with a history of ROP with or without treatment have an increased risk for late ocular sequelae, such as high myopia, retinal detachment, vitreous hemorrhage and strabismus. A seamless transition from ROP screening to pediatric and ophthalmological follow-up care is therefore essential for timely detection and treatment of possible refractive errors, strabismus, or other amblyogenic changes.

Prevalence and Incidence of Registered Severe Visual Impairment and Blindness Due to Uveitis in Germany.

PURPOSE: To assess prevalence and incidence of severe visual impairment (VI) and blindness due to uveitis in Northrhine, Germany. METHODS:  A random sample of 5088 out of 20 390 cases of the blindness registry in Northrhine was evaluated. The number of cases of severe VI and blindness were projected up to the year 2030. RESULTS: The prevalence of registered severe VI and blindness due to uveitis was 1123.9 (95% CI: 1059.5 to 1191.2) per 100 000 in our study cohort and 550.31 (95% CI: 365.98-794.38) per 100 000 in Northrhine, respectively. The incidence of registered severe VI and blindness due to uveitis was 311.8 per 100 000 PYs (95% CI: 149.6-572.7) in our study cohort and 11.1 per 100 000 (95% CI: 5.6-19.8) in Northrhine, respectively. CONCLUSIONS: We report prevalence and incidence of severe VI and blindness due to uveitis in a large German cohort.

[Retinopathy of Prematurity - Update on Classification, Screening, and Therapy]. / Frühgeborenenretinopathie.

Retinopathy of prematurity (ROP) is a leading cause of preventable childhood blindness. This proliferative retinal vascular disease affects only prematurely born infants. Major risk factors include low gestational age and prolonged postnatal oxygen supplementation. ROP screening allows for timely identification of treatment-requiring infants and thus significantly reduces the risk of severe visual impairment and blindness from ROP. Current treatment options comprise retinal laser coagulation and intravitreal anti-vascular endothelial growth factor (VEGF) therapy. We provide a review of scientific data and current treatment recommendations, with special attention to the updated German guideline on ROP screening, the statement of the German ophthalmological societies on anti-VEGF therapy of ROP, and the new third edition of the International Classification of Retinopathy of Prematurity (ICROP3).

Incidence, progression and risk factors of age-related macular degeneration in 35-95-year-old individuals from three jointly designed German cohort studies.

OBJECTIVE: To estimate age-related macular degeneration (AMD) incidence/progression across a wide age range. METHODS AND ANALYSIS: AMD at baseline and follow-up (colour fundus imaging, Three Continent AMD Consortium Severity Scale, 3CACSS, clinical classification, CC) was assessed for 1513 individuals aged 35-95 years at baseline from three jointly designed population-based cohorts in Germany: Kooperative Gesundheitsforschung in der Region Augsburg (KORA-Fit, KORA-FF4) and Altersbezogene Untersuchungen zur Gesundheit der Universität Regensburg (AugUR) with 18-year, 14-year or 3-year follow-up, respectively. Baseline assessment included lifestyle, metabolic and genetic markers. We derived cumulative estimates, rates and risk factor association for: (1) incident early AMD, (2) incident late AMD among no AMD at baseline (definition 1), (3) incident late AMD among no/early AMD at baseline (definition 2), (4) progression from early to late AMD. RESULTS: Incidence/progression increased by age, except progression in 70+-year old. We observed 35-55-year-old with 3CACSS-based early AMD who progressed to late AMD. Predominant risk factor for incident late AMD definition 2 was early AMD followed by genetics and smoking. When separating incident late AMD definition 1 from progression (instead of combined as incident late AMD definition 2), estimates help judge an individual's risk based on age and (3CACSS) early AMD status: for example, for a 65-year old, 3-year late AMD risk with no or early AMD is 0.5% or 7%, 3-year early AMD risk is 3%; for an 85-year old, these numbers are 0.5%, 21%, 12%, respectively. For CC-based 'early/intermediate' AMD, incidence was higher, but progression was lower. CONCLUSION: We provide a practical guide for AMD risk for ophthalmology practice and healthcare management and document a late AMD risk for individuals aged <55 years.

Treatment Exit Options for Non-infectious Uveitis (TOFU): Study Protocol for a Prospective Clinical Registry.

PURPOSE: Currently, there is limited evidence regarding clinical management of non-anterior non-infectious uveitis including treatment outcomes of disease-modifying anti-rheumatic drugs (DMARDs) and their combinations. Treatment guidelines or recommendations on preferred choice of DMARD combinations and reduction and/or discontinuation strategies in quiescent uveitis are lacking. The TOFU (Treatment exit options for non-infectious uveitis) registry aims to document disease courses and to provide recommendations on DMARD treatment exit strategies. METHODS: The registry is an observational, non-commercial, and non-interventional study and targets patients who are ≥18 years of age with non-infectious uveitis of the posterior segment or retinal vasculitis on or starting DMARD treatment. Data are entered prospectively at study sites through a web-based interface into electronic case report forms (eCRF) implemented in the electronic data capture software RedCap (Version 9, Vanderbilt University, USA). The collated data include ophthalmological, general medical history and patient-reported outcomes (PROs). Assessment of uveitis classification and activity follows the international Standardization of uveitis nomenclature (SUN) criteria. Patient appointment and treatment decisions remain at the discretion of the managing physician and are completely independent of participation in the registry. The study follows the tenets of the declaration of Helsinki. CONCLUSIONS: The TOFU registry captures real-life data of patients with non-infectious uveitis of the posterior segment, involving both medical personnel and patients. The study adheres to international standards and will provide important evidence and guidance in the development of guidelines.

Uveitis in Tumor Patients Treated with Immunological Checkpoint- and Signal Transduction Pathway-Inhibitors.

PURPOSE: New tumor therapies like immune checkpoint inhibitors and small molecule inhibitors of MEK and BRAF have increased the patient's survival rate but can be burdened with severe side-effects including uveitis. Here, we show the spectrum, treatment, and outcome of uveitis types induced by tumor treatment. METHODS: In this retrospective study, we have included 54 patients from different centers who were developing uveitis under tumor therapy. A 16-item questionnaire was analyzed for type, treatment, and outcome of uveitis and type of tumor treatment, which we have correlated here. RESULTS: Irrespective of the tumor treatment, most patients developed anterior uveitis. All patients received corticosteroids and some additional immunosuppressive treatments. Cessation of tumor therapy was necessary only in a minority of cases. CONCLUSIONS: Ocular autoimmunity should be differentiated from toxic effects of cancer treatment and timely recognized since it can be generally well controlled by anti-inflammatory treatment, preserving the patient's vision without cessation of the tumor treatment.

[The Treatment Exit Options for Uveitis (TOFU) Registry: Involving Patients in the Generation of Evidence]. / Das Treatment Exit Options for Uveitis (TOFU) Register: Einbindung von Patienten in die Evidenzgenerierung.

Uveitis comprises a group of rare diseases characterised by intraocular inflammation which may cause vision impairment and blindness and mostly affects people of working age. Non-infectious uveitis involving the posterior pole or the entire eye is often treated with different immunomodulating or disease-modifying anti-rheumatic drugs (DMARDs). However, the evidence on long-term management strategies and reduction/termination of treatment is limited. To help develop treatment exit strategies for patients with quiescent uveitis on long-term DMARD treatment, the Treatment Exit Options for Non-infectious Uveitis registry was initiated by the German ophthalmological society. A key aspect of the registry is active participation of patients (patient-reported outcomes, PROs). In a pilot study involving members of patient organizations, a combination of questionnaires covering vision- and general health-related quality of life, adherence to treatment, productivity and effects of treatment were evaluated. As the pilot study showed coverage of relevant patient-related aspects of the disease and its effect on daily life, the evaluated questionnaires were implemented in the registry's patient module. The registry including the patient module uses the electronic data capture (EDC) software REDCap (Version 9, Vanderbilt University, USA). By involving patients in both conceptualization and ongoing data collection, the TOFU registry emphasizes the patients' perspectives, and the inclusion of patient-relevant evidence for such as the development of guidelines and treatment recommendations is ensured.

Structural Endpoints and Outcome Measures in Uveitis.

Most uveitis entities are rare diseases but, taken together, are responsible for 5-10% of worldwide visual impairment which largely affects persons of working age. As with many rare diseases, there is a lack of high-level evidence regarding its clinical management, partly due to a dearth of reliable and objective quantitative endpoints for clinical trials. This review provides an overview of available structural outcome measures for uveitis disease activity and damage in an anatomical order from the anterior to the posterior segment of the eye. While there is a multitude of available structural outcome measures, not all might qualify as endpoints for clinical uveitis trials, and thorough testing of applicability is warranted. Furthermore, a consensus on endpoint definition, standardization, and "core outcomes" is required. As stipulated by regulatory agencies, endpoints should be precisely defined, clinically important, internally consistent, reliable, responsive to treatment, and relevant for the respective subtype of uveitis. Out of all modalities used for assessment of the reviewed structural outcome measures, optical coherence tomography, color fundus photography, fundus autofluorescence, and fluorescein/indocyanine green angiography represent current "core modalities" for reliable and objective quantification of uveitis outcome measures, based on their practical availability and the evidence provided so far.

[Screening for retinopathy of prematurity-the most important changes in the new German guidelines 2020]. / Screening auf Frühgeborenenretinopathie ­ die wichtigsten Änderungen in der neuen deutschen Leitlinie 2020.

BACKGROUND: Due to improvements in neonatal care of premature infants and the development of novel treatment options for retinopathy of prematurity (ROP), the requirements for screening for ROP have changed since publication of the last version of the German ROP screening guideline in 2008. Based on results of recent studies, the guideline has been extensively revised in 2020 and published in an updated version. OBJECTIVE: This article summarizes the most important changes in the new guideline. RESULTS: The age limit for screening inclusion was lowered to a gestational age of below 31 weeks for infants without additional risk factors. The minimum duration of oxygen supplementation necessitating screening inclusion in preterm infants was increased to more than 5 days. Treatment for ROP in zone II can now be given at any stage 3 with plus disease, regardless of the number of clock hours affected. Criteria for the frequency and duration have been defined for follow-up examinations after anti-vascular endothelial growth factor (VEGF) treatment. The binding document for these and other new recommendations is the guideline itself. CONCLUSION: The guideline recommendations enable a reliable identification of infants at risk for ROP for screening inclusion and a timely detection of advanced disease stages for treatment initiation, thus preventing blindness from ROP.

Silicone oil tamponade for persistent macular holes.

BACKGROUND: A variety of treatment strategies have been proposed for macular holes that persist or recur after surgery, and the debate about the best re-treatment approach is ongoing. To allow for a comparison with alternative surgical therapies, we assessed the anatomical and functional outcome of a temporary tamponade with conventional silicone oil in persistent or recurrent full-thickness macular holes. METHODS: We retrospectively investigated consecutive patients with full-thickness macular holes that persisted or recurred following vitrectomy with internal limiting membrane peeling and gas tamponade. All patients received re-treatment by temporary tamponade of silicone oil and were allowed free postoperative positioning. Anatomical closure rate was assessed by optical coherence tomography, and change of best-corrected visual acuity (BCVA) was analyzed. RESULTS: A total of 33 eyes of 33 consecutive patients were included. Macular hole closure following silicone oil tamponade was achieved in 30 of 33 eyes (90.9%). Median BCVA improved from 1.00 logMAR (interquartile range, 0.60-1.00) to 0.65 logMAR (0.49-1.00; p = 0.010) after silicone oil removal. In patients with macular hole closure, 61.3% exhibited functional improvement with median BCVA changing from 1.00 logMAR (0.70-1.00) to 0.60 logMAR (0.49-1.00; p = 0.0005). Mean minimal linear diameter of macular holes before primary surgery was 391.0 µm (±137.8; range 133-630), and 48.5% of macular holes were >400 µm in diameter. CONCLUSIONS: Treatment of persistent or recurrent full-thickness macular holes by temporary conventional silicone oil tamponade without postoperative positioning results in a high closure rate and a significant mean improvement of visual acuity.

Prevalence and incidence of age-related macular degeneration in Europe: a systematic review and meta-analysis.

BACKGROUND/AIMS: Age-related macular degeneration (AMD) is the main cause of visual impairment and blindness in Europe. A further increase in the number of affected persons is expected and current European data are needed for healthcare resource planning. METHODS: We performed a systematic review on the prevalence and incidence of AMD based on the meta-analysis of observational studies in epidemiology guideline. Meta-analysis and meta-regression on time-trends, age, countries, regions, sex and classification systems for AMD were performed. Based on Eurostat population projections, the pooled prevalence estimates were extrapolated to the year 2050. RESULTS: Twenty-two prevalence and four incidence studies published since 1996 were included. Our pooled prevalence estimate of early or intermediate AMD and any late AMD in those 60 years and older was 25.3% (95% CI 18.0% to 34.4%) and 2.4% (95% CI 1.8% to 3.3%), respectively. A significant increase in prevalence was seen in older populations. In the meta-analysis of incidence, the pooled annual incidence of any late AMD was 1.4 per 1 000 individuals (95% CI 0.8 to 2.6). Overall, the number of EU inhabitants with any AMD is expected to increase from 67 to 77 million until 2050. Incident late AMD is estimated to increase from 400 000 per year today to 700 000 per year in 2050. CONCLUSIONS: Approximately 67 million people in the EU are currently affected by any AMD and, due to population ageing, this number is expected to increase by 15% until 2050. Monitoring and treatment of people with advanced disease stages will require additional healthcare resources and thorough healthcare planning in the years and decades to come.

Prevalence, incidence and future projection of diabetic eye disease in Europe: a systematic review and meta-analysis.

To examine the prevalence and incidence of diabetic eye disease (DED) among individuals with diabetes in Europe, a systematic review to identify all published European prevalence and incidence studies of DED in individuals with diabetes managed in primary health care was performed according to the MOOSE and PRISMA guidelines. The databases Medline, Embase and Web of Science were searched to 2 September 2017. Meta-analyses and meta-regressions were performed. The pooled prevalence estimates were applied to diabetes prevalence rates provided by the International Diabetes Foundation atlas and Eurostat population data, and extrapolated to the year 2050. Data of 35 prevalence and four incidence studies were meta-analyzed. Any diabetic retinopathy (DR) and diabetic macular edema (DME) were prevalent in 25.7% (95% CI 22.8-28.8%) and 3.7% (95% CI 2.2-6.2%), respectively. In meta-regression, the prevalence of DR in persons with type 1 diabetes was significantly higher compared to persons with type 2 diabetes (54.4% vs. 25.0%). The pooled mean annual incidence of any DR and DME in in persons with type 2 diabetes was 4.6% (95% CI 2.3-8.8%) and 0.4% (95% CI 0.5-1.4%), respectively. We estimated that persons with diabetes affected by any DED in Europe will increase from 6.4 million today to 8.6 million in 2050, of whom 30% require close monitoring and/or treatment. DED is estimated to be present in more than a quarter of persons with type 2 diabetes and half of persons with type 1 diabetes underlining the importance of regular monitoring. Future health services need to be planned accordingly.

Non-contact smartphone-based fundus imaging compared to conventional fundus imaging: a low-cost alternative for retinopathy of prematurity screening and documentation.

Retinopathy of prematurity (ROP) is a frequent cause of treatable childhood blindness. The current dependency of telemedicine-based ROP screening on cost-intensive equipment does not meet the needs in economically disadvantaged regions. Smartphone-based fundus imaging (SBFI) allows for affordable and mobile fundus examination and, therefore, could facilitate cost-effective telemedicine-based ROP screening in low-resources settings. We compared non-contact SBFI and conventional contact fundus imaging (CFI) in terms of feasibility for ROP screening and documentation. Twenty-six eyes were imaged with both SBFI and CFI. Field-of-view was smaller (ratio of diameters, 1:2.5), level of detail was equal, and examination time was longer for SBFI as compared to CFI (109.0 ± 57.8 vs. 75.9 ± 36.3 seconds, p < 0.01). Good agreement with clinical evaluation by indirect funduscopy was achieved for assessment of plus disease and ROP stage for both SBFI (squared Cohen's kappa, 0.88 and 0.81, respectively) and CFI (0.86 and 0.93). Likewise, sensitivity/specificity for detection of plus disease and ROP was high for both SBFI (90%/100% and 88%/93%, respectively) and CFI (80%/100% and 100%/96%). SBFI is a non-contact and low-cost alternative to CFI for ROP screening and documentation that has the potential to considerably improve ROP care in middle- and low-resources settings.

Impact of visual impairment on physical activity in early and late age-related macular degeneration.

BACKGROUND: Modifiable risk factors for age-related macular degeneration (AMD) include smoking, nutrition and likely physical activity (PA). Levels of PA, however, are impacted by any visual impairment which makes the assessment of any association with AMD difficult. PURPOSE: To assess the impact of visual impairment under both high and low luminance conditions on levels of PA in early and late AMD. METHODS: Ninety participants with early to late AMD underwent a clinical assessment including conventional best-corrected visual acuity, low luminance visual acuity, contrast sensitivity and the Moorfields acuity test. PA was recorded using a wrist-worn accelerometer (GENEActiv, Activeinsights) on seven consecutive days. Patient characteristics were compared with the Wilcoxon rank-sum test and determinants of moderate-to-vigorous-PA (MVPA) were assessed using linear regression models. RESULTS: Mean age was 73.9 ± 8.5 years (range 50-89) and 47 subjects (52.2%) were women. Average MVPA time was longer in the early (355.1 ± 252.0 minutes/week) compared to the late AMD group (162.2 ± 134.6 minutes/week; p<0.001). Using linear regression, age [ß = -0.25; 95% confidence interval (CI): -12.9; -0.8, p = 0.028] and AMD stage (ß = -0.28; 95% CI: -230.9, -25.0; p = 0.015) but not visual impairment on any of the employed tests were associated with MVPA (minutes/week). CONCLUSIONS: We found late AMD to be associated with reduced PA. As performance on any of the visual tests was not associated with PA, this association cannot entirely be explained by functional impairment. More research is needed to further explore the association of PA and AMD as PA may be a potentially modifiable risk factor.

Incidence of Rhegmatogenous Retinal Detachment in Europe - A Systematic Review and Meta-Analysis.

PURPOSE: To examine the prevalence and incidence of rhegmatogenous retinal detachment (RRD) in Europe. METHODS: A systematic review of the prevalence and incidence of RRD in Europe according to the meta-analyses of observational studies in epidemiology (MOOSE) guidelines was performed using the databases PubMed, Embase, and Web of Science followed by a meta-analysis of incidence data. RESULTS: 658 studies were identified, 76 full-text articles were assessed, and 5 studies were eligible for meta-analysis. Random-effects pooled mean annual incidence of RRD in Europe was 13.3 cases per 100,000 inhabitants (95% CI: 11.3-15.6) based on the examination of 95,765 individuals from the 5 incidence studies. No European studies reporting prevalence of retinal detachment were identified. CONCLUSION: Published articles on the prevalence and incidence of RRD in Europe are limited. Further epidemiological research is needed for adequate healthcare planning.
