- Abstract
We report on the hot-wall MOCVD growth of Mg-doped AlxGa1-xN layers with an Al content as high as x similar to 0.85. After subjecting the layers to post-growth in-situ annealing in nitrogen in the growth reactor, a room temperature resistivity of 7 k Omega cm was obtained indicating an enhanced p-type conductivity compared to published data for AlxGa1-xN layers with a lower Al content of x similar to 0.70 and a room temperature resistivity of about 10 k Omega cm. It is believed that the enhanced p-type conductivity is a result of reduced compensation by native defects through growth conditions enabled by the distinct hot-wall MOCVD system.

- Abstract
Purpose: The aim of the study is to analyze the swept source-optical coherence tomography angiography (SS-OCTA) characteristics of polypoidal lesions in Caucasian patients., Methods: In this retrospective observational case series, 43 polypoidal lesions in 32 eyes of 32 patients were diagnosed using indocyanine green angiography (ICGA) and compared to SS-OCTA at a tertiary medical retina center (Clinic Landstra ß e, Vienna Healthcare Group, Austria) between June 2017 and March 2020. Vascularity was identified by color-coded B-scan SS-OCTA while morphology was described as revealed by en face SS-OCTA after alignment with ICGA-confirmed findings., Results: In total, SS-OCTA detected all polypoidal lesions, as identified by ICGA. On B-scan SS-OCTA, circumscribed flow was detected in 33 (76.7%) polypoidal lesions and diffuse flow in 10 (23.3%) lesions. On en face SS-OCTA, polypoidal lesions appeared morphologically as 19 tangled vessel balls (44.2%), 6 tangled vessel balls next to dilated vessels (13.9%), 8 vascular dilatations (18.6%), and 8 ill-defined vascular networks (18.6%), leaving 2 lesions (4.6%) undetected. Circumscribed flow was significantly associated with tangled vessel balls ( p = 0.005)., Conclusion: This study highlights the importance of a multimodal imaging approach, including SS-OCTA, for the evaluation of polypoidal lesions. Our findings suggest a morphological heterogeneity of vascular patterns in Caucasian patients with polypoidal lesions, as pictured by SS-OCTA., Competing Interests: The authors declare that there are no conflicts of interest., (Copyright © 2023 Daniel Ahmed-Balestra et al.)

- Abstract
Introduction: We aimed to evaluate visual and anatomical outcomes among eyes with neovascular age-related macular degeneration (nAMD) that were persistent to intravitreal aflibercept therapy compared to those that were nonpersistent to therapy., Methods: We audited 648 treatment-naïve eyes of 559 patients regarding visual acuity (VA) given as the logarithm of the minimum angle of resolution (logMAR) and anatomic outcomes at baseline and at each subsequent follow-up visit for up to 5 years. Nonpersistence was defined as a visit-free interval of > 6 months., Results: Among the enrolled eyes, 405 were persistent to the therapy and 243 (37%) were nonpersistent, of which 161 (66%) eyes returned for further therapy after a gap of clinical care. In the nonpersistent group, we observed a decline from 0.58 ± 0.35 to 0.92 ± 0.57 logMAR (p = 0.01) after 60 months. Compared with the persistent group, the nonpersistent group had worse visual outcomes at their 33-month (p = 0.03), 42-month (p = 0.01), 51-month (p = 0.001) and 60-month (p = 0.01) visits. Additionally, 5/405 (1.2%) eyes in the persistent group and 8/161 (5.0%) eyes in the nonpersistent group developed an end-stage disease with a subfoveal fibrosis during the observational period (p = 0.013)., Conclusion: We found that eyes with nAMD that were nonpersistent to intravitreal aflibercept therapy experienced statistically significantly worse VA compared to eyes persistent to therapy within 3 years. Moreover, eyes in the nonpersistent group had a four-fold higher risk of developing a fovea-involving fibrosis. Considering the potential irreversible deterioration with respect to best-corrected VA within nAMD, strategies need to be developed for patients at risk of nonpersistence to therapy., (© 2022.

- Abstract
Introduction: To evaluate the effect of a 9-week treatment deferral due to healthcare restrictions caused by Austria's first governmental lockdown associated with the coronavirus disease 2019 (COVID-19) pandemic on visual acuity (VA) in eyes compromised by exudative neovascular age-related macular degeneration (nAMD) after 1 year., Methods: Retrospective data collection of 98 eyes (98 patients) with a treatment discontinuation at a tertiary eye care center (Clinic Landstraße, Vienna Healthcare Group, Austria) between March 16 and May 4, 2020. Prior to the lockdown, patients received multiple intravitreal injections (IVI) of anti-vascular endothelial growth factor with a personalized treatment interval for 3 years on average and at least three IVI after the lockdown., Results: When the treatment interval doubled to 117.6 ± 31.4 days in spring 2020, patients lost 2.2 ± 4.6 ETDRS letters (p = 0.002) on average before reinitiating therapy. In total, 4.1 ± 8.1 letters (p < 0.0001) were lost despite continuous individual re-treatment over the course of the next year. In a univariate analysis, the extended interval time remained statistically significant (p < 0.0001), indicating a larger VA reduction within intervals with increasing interval time in days., Conclusion: The short-term treatment interruption had a persistent negative impact on the VA course of eyes under therapy after 1 year. Continuous therapy independent of the underlying treatment regimen remains of utmost importance in exudative nAMD. Our data should create awareness to regulators regarding future decisions despite the global pandemic., (© 2021. The Author(s).)

- Abstract
The purpose was to demonstrate the diagnostic and therapeutic feasibility of swept source-optical coherence tomography angiography (SS-OCTA) by picturing neovascular changes secondary to a rare white dot syndrome following long-term intravitreal ranibizumab (IVR). A 28-year-old Caucasian myopic female presented with visual loss in her right eye only. The clinical examination and multimodal imaging including spectral domain (SD)-OCT, blue-peak autofluorescence, fluorescein, and indocyanine green angiography (HRA Spectralis, Heidelberg Engineering; Heidelberg, Germany) as well as SS-OCTA (DRI Triton, Topcon; Tokyo, Japan) led to the diagnosis of idiopathic punctate inner choroidopathy with secondary subfoveal choroidal neovascularization (CNV). In addition to oral corticosteroids, a pro re nata regimen with IVR was initiated and guided by repeated SD-OCT and SS-OCTA. Six IVR were administered based on functional SS-OCTA en face scans illustrating vessel transformation and downsizing of the CNV area while SD-OCT B-scans were inconclusive as indirect signs of activity were absent throughout the follow-up period. SS-OCTA provided new possibilities for monitoring vessel development. IVR was managed based on vessel density as displayed by SS-OCTA., Competing Interests: The authors have no conflicts of interest to declare., (Copyright © 2021 by S. Karger AG, Basel.)

- Abstract
Objectives This study aimed to investigate whether change from the construction industry to work in other industries at age 45-55 years lowered risks of disability benefits (DB) later in life (60-64 years of age). We hypothesized that risks would be lowered the most among those changing from the heaviest occupations. Methods The study included men employed in the construction industry during 1971-1993. We selected workers from the largest occupational groups in heavy (concrete workers and painters) and less heavy (drivers, electricians and foremen) occupations. The occurrence of DB in 1990-2015 was retrieved from national registers. Regression analyses were used to calculate relative risks (RR) of DB at 60-64 years, comparing those working in other industries to those still in the construction industry at the age of 45, 50 and 55 years. Results Shifting out of from the construction industry was related to lowered DB risks at 60-64 years in all selected occupations. Effects were most pronounced among those who, at 55 years of age, worked in an industry other than construction, with significantly reduced RR for DB among concrete workers [RR 0.63, 95% confidence interval (CI) 0.51-0.77], electricians (RR 0.61, 95% CI 0.47-0.77) and foremen (RR 0.78, 95% 0.63-0.96). Conclusions Risks for DB at 60-64 years of age were reduced among those who changed from construction work to other industries. Notable reductions were observed among workers originating from both heavy and less heavy occupations, and future studies should explore other factors, in addition to heavy workload, as motivators for leaving the construction industry.

- Abstract
Purpose: To compare the lesion sizes of macular neovascularization (MNV) imaged with spectral-domain (SD) and swept-source (SS) optical coherence tomography angiography (OCTA) as well as indocyanine green angiography (ICGA)., Methods: In this prospective, observational case series, patients showing a secured diagnosis of MNV on ICGA or Fluorescein Angiography, were imaged by SD-OCTA and SS-OCTA on the same day. Lesion size was measured on 3 × 3-mm
2 and 6 × 6-mm2 scans using the Maestro 2 SD-OCTA (Topcon Corporation, Tokyo Japan) and the Triton SS-OCTA device (Topcon Corporation, Tokyo Japan) and compared to ICGA (Spectralis HRA, Heidelberg, Germany)., Results: Twenty eyes from 20 patients (11 females, 55%) were enrolled. The neovascularization area measured on 6 × 6-mm2 SD-OCTA was lower compared to that outlined on SS-OCTA, however, not reaching statistical significance (p = 0.094). Regarding 3 × 3-mm2 measurements, the median lesion sizes between the two OCTA devices were comparable (p = 0.492). Indocyanine green angiography depicted a larger lesion area than both OCTA devices, however, not reaching statistical significance., Conclusion: SD-OCTA tends to show smaller areas of MNV extension than SS-OCTA regarding 6 × 6 mm2 scans. The lesion size of MNV can be very well compared between the different devices, emphasizing the use of OCTA for monitoring neovascular area. Lesion measurements on SS-OCTA correlate better with ICGA than SD-OCTA., (© 2020 Acta Ophthalmologica Scandinavica Foundation. Published by John Wiley & Sons Ltd.)- Published

- Abstract
Purpose: To evaluate the capability of swept source-optical coherence tomography angiography (SS-OCTA) in the detection and localization of treatment-naive macular neovascularization (MNV) secondary to exudative neovascular age-related macular degeneration (nAMD)., Methods: In this prospective, observational case series, 158 eyes of 142 patients were diagnosed with exudative nAMD using fluorescein (FA) and indocyanine green angiography (ICGA) and evaluated by SS-OCTA in a tertiary retina center (Rudolf Foundation Hospital Vienna, Austria). The main outcome measure was the sensitivity of SS-OCTA compared to the standard multimodal imaging approach. Secondary outcome measure was the anatomic analysis of MNV in relation to the retinal pigment epithelium., Results: En-face SS-OCTA confirmed a MNV in 126 eyes (sensitivity: 79.8%), leaving 32 eyes (20.2%) undetected. In 23 of these 32 eyes (71.9%), abnormal flow in cross-sectional SS-OCTA B-scans was identified, giving an overall SS-OCTA sensitivity of 94.3%. Eyes with a pigment epithelium detachment (PED) ≥ 300 μ m had a smaller probability for correct MNV detection ( p =0.015). Type 1 MNV showed a trend ( p =0.051) towards smaller probability for the correct detection compared to all other subtypes. Other relevant factors for the nondetection of MNV in SS-OCTA were image artifacts present in 3 of 32 eyes (9.4%). SS-OCTA confirmed the anatomic localization of 93 in 126 MNVs as compared to FA (sensitivity: 73.8%). There was no influence of age, gender, pseudophakia, visual acuity, central foveal thickness, or subfoveal choroidal thickness on the detection rate of MNV., Conclusions: SS-OCTA remains inferior to dye-based angiography in the detection rate of exudative nAMD consistent with type 1 MNV and a PED ≥300 µ m. The capability to combine imaging modalities and distinguish the respective MNV subtype improves its diagnostic value., Competing Interests: All authors declare no conflicts of interest related to this submission., (Copyright © 2021 Daniel Ahmed et al.)

- Abstract
Diabetic maculopathy (DM) is a microvascular dysfunction clinically characterized by microaneurysms (MA) leading to edema and central visual deprivation. This prospective explorative study investigated 27 eyes of 17 patients with DM by fluorescein/indocyanine green angiography (FA/ICGA; SPECTRALIS HRA-OCT, Heidelberg Engineering) and by swept source-optical coherence tomography angiography (SS-OCTA; DRI-OCT Triton Plus, Topcon) to identify clinically relevant MAs. The SS-OCTA cubes were split into the superficial capillary plexus (SCP) and the deep capillary plexus (DCP) according to the automated segmentation. The images of all modalities were superimposed for alignment by an Early Treatment Diabetic Retinopathy Study grid overlay and compared to each other. In total, the mean number of MAs in FA was 33.4 ± 22 (standard deviation) (median 27.5 [q1:21.75;q3:38.25]), in ICGA 24.9 ± 16.9 (17.5 [14;35]), in the SCP 6.5 ± 3.7 (5.5 [3.75;9.25]) and in the DCP 18.1 ± 10.5 (18.5 [10.75;23.5]). Mixed effects models between ICGA and the DCP were borderline significant (p = 0.048; 95% confidence interval 0.21 to 13.49), whereas all other imaging methods differed significantly. Quantitative analysis of MAs in DM showed a plausible agreement between ICGA and the DCP in SS-OCTA. These findings contribute to the imaging methodology in DM.

- Abstract
Background: Type 2 macular neovascularization (MNV) is supposed to be a rare condition in age-related macular degeneration (AMD). The main purpose of this study was to assess accompanying factors of type 2 MNV in AMD., Methods: Retrospective data analysis of eyes previously diagnosed with neovascular AMD in a tertiary eye care center (Medical Retina Unit, Rudolf Foundation Hospital, Vienna, Austria) between June 2008 and December 2017. Drusen subtypes, fibrosis, atrophy and subfoveal choroidal thickness (SFCT) of both eyes in patients with type 2 MNV lesions were categorized based on multimodal imaging., Results: Type 2 MNV was diagnosed in 27 (3.2%) of 835 eyes (749 patients). Drusen characteristics in type 2 MNV were observed as followed: drusen < 63 μm in 2 eyes (7.4%), drusen ≥63 μm in 10 eyes (37%), subretinal drusenoid deposits (SDD) in 8 eyes (29.6%), cuticular drusen in 2 eye (7.4%) and no drusen were evident in 10 eyes (37%). Drusen distribution in 23 fellow eyes was detected as followed: drusen < 63 μm in 2 eyes (8.7%), drusen ≥63 μm in 9 eyes (39.1%), SDD in 5 eyes (21.7%), cuticular drusen in 1 eye (4.3%) and no drusen were evident in 9 eyes (39.1%). Mean SFCT was 140 ± 49 μm in affected eyes and 152 ± 41 μm in the fellow eyes. Patients with drusen or SDD were significantly younger (mean 70.88 ± 6.85, p = 0.04) than patients without deposits (mean 77.40 ± 5.74)., Conclusions: Type 2 MNV remains a rare entity in AMD. It was frequently seen in the absence of drusen, a hallmark of AMD. These findings contribute to the heterogeneity of phenotypes related to pure type 2 lesions.

- Abstract
Purpose: To evaluate normalized short-wavelength fundus autofluorescence (SW-FAF) imaging changes over time as a predictive parameter for the retinal pigment epithelium (RPE) function in eyes compromised by acute central serous chorioretinopathy (CSCR) after indocyanine green angiography-guided verteporfin (Visudyne®, Novartis Pharma, Basel, Switzerland) photodynamic therapy (PDT) with a half-fluence rate (25 J/cm
2 )., Methods: Quantitative data of SW-FAF grey values (SW-FAF GV) from a 350 μ m (SW-350) and 1200 μ m (SW-350) and 1200 t -test was calculated to explore the differences of SW-350 and SW-1200 between one month and the long-term follow-up., Results: Mean differences (95% CI) in SW-FAF GV between 1 month and 7 years after half-fluence PDT were 0.07 ± 0.11 for SW-350 ([95% CI: -0.002; 0.14], p =0.06) and 0.11 ± 0.15 for SW-1200 ([95% CI: 0.01; 0.21], p =0.06) and 0.11 ± 0.15 for SW-1200 ([95% CI: 0.01; 0.21], p =0.06) and 0.11 ± 0.15 for SW-1200 ([95% CI: 0.01; 0.21], p =0.06) and 0.11 ± 0.15 for SW-1200 ([95% CI: 0.01; 0.21]., Conclusion: After 7 years, normalized SW-FAF GV were significantly lower in eyes with resolved acute CSCR treated with reduced-fluence PDT compared to the follow-up after 1 month without correlation to explicit pattern changes or structural damages. Half-fluence PDT remains a safe and considerable treatment option in acute CSCR., Competing Interests: The authors declare that they have no conflicts of interest., (Copyright © 2020 Martin Stattin et al.)- Published

- Abstract
Purpose: To evaluate 7-year visual and anatomical outcomes of intravitreal injections (IVI) with antivascular endothelial growth factor (anti-VEGF) for neovascular age-related macular degeneration (nAMD) based on a personalized pro re nata (PRN) regimen., Methods: Anonymized data of 124 consecutive eyes in 121 patients with treatment-naïve nAMD were initially collected in 2010. Of those, 45 received anti-VEGF IVI at least every 6months until 2017 in one single center in Austria and hence were retrospectively analyzed. All eyes had been initiated on a loading dose of 3 monthly IVI with different anti-VEGF agents followed by a PRN regimen in the first year. At year 2, monitoring as well as therapeutic intervention could be prolonged every 2weeks up to intervals of 3months without capping treatment. Primary outcome measure was the change of visual acuity (VA) assessed by Early Treatment Diabetic Retinopathy Study charts at 4 meters (ETDRS) in letters-counting every correctly read letter-and converted to Snellen. Secondary outcome measures were number of injections and change of central retinal thickness (CMT) from baseline., Results: Mean baseline VA was 20/63 + 1 (0.63 ± 0.26 ETDRS) and declined to 20/100 + 2 (0.45 ± 0.33) with an overall loss of 9 letters ETDRS after 7years ( p = 0.001). An average of 3.5 ± 1.9 IVI was given per year and eye. Mean CMT at baseline was 322 ± 95 μ m, decreased by 52 μ m, decreased by 52 μ m, decreased by 52 μ m, decreased by 52 μ m to 270 ± 70 μ m within the first year, and remained below baseline at year 7 (271 ± 106 μ m; p = 0.001). An average of 3.5 ± 1.9 IVI was given per year and eye. Mean CMT at baseline was 322 ± 95 μ m, decreased by 52 μ m to 270 ± 70 μ m within the first year, and remained below baseline at year 7 (271 ± 106 μ m; p < 0.001)., Conclusions: Our data confirm an absolute vision loss in eyes compromised by nAMD after 7 years of continuous VEGF inhibition. The visual decline was significantly related to baseline VA as well as the number of injections. We suggest following patients thoroughly independent of the initial VA and a greater incentive for the physician to treat., Competing Interests: The authors declare that there are no conflicts of interest regarding the publication of this article., (Copyright © 2020 Martin Stattin et al.)

- Abstract
Purpose: To assess the relationship between signs of activity in exudative neovascular age-related macular degeneration (nAMD) following anti-vascular endothelial growth factor (anti-VEGF) treatment and morphology of choroidal neovascularization (CNV) based on neovascular density as imaged using swept source-optical coherence tomography angiography (SS-OCTA) in a qualitative manner., Methods: A single-cohort retrospective data analysis from one tertiary eye care center. Seventy-seven eyes of 72 patients were included and their charts reviewed which had been started on intravitreal injections with anti-VEGF for nAMD at least one year prior to enrollment. Clinically active disease was evaluated by slit-lamp fundus examination and spectral domain-OCT B-scans. Morphological appearance in SS-OCTA was characterized based on 5 different criteria and subsequently divided into 3 groups: predominantly hyperdense, minimally hyperdense, and hypodense lesions., Results: Fifty-eight eyes (75%) were considered clinically active and 19 eyes (25%) clinically inactive. CNV was depicted in 71 eyes (92%) by SS-OCTA and separated accordingly into predominantly hyperdense (32%), minimally hyperdense (34%), and hypodense lesions (34%). A borderline significant difference in the probability of neovascular activity for predominantly hyperdense lesions compared to hypodense lesions was detected ( p =0.05)., Conclusions: Hyperdense choroidal neovascularization based on qualitative assessment of flow density showed a significant relation to active disease. Inactivity could not be matched adequately. This study demonstrated the potential usefulness of SS-OCTA for guidance of treatment in age-related macular degeneration.

- Abstract
This case illustrates that hematologic disorders must be considered as a potentially life-threatening cause for vision loss. Proper laboratory workup and timely interdisciplinary approach are essential to ensure the best possible care for ophthalmic patients. Historically, before the use of bone marrow biopsy, the ophthalmologist was often asked to assist in the diagnosis of leukemia. Since ophthalmological symptoms may be the initial presenting signs of leukemia as highlighted in this case, the ophthalmogist is still of crucial importance.

- Abstract
Purpose: Placental growth factor (PlGF) has been implicated as a contributor to resistance against anti-VEGF therapy. The purpose of the present study was to analyze the systemic levels of PlGF, VEGF-A, and VEGF-B in patients with neovascular age-related macular degeneration (AMD) after treatment with aflibercept, ranibizumab, or bevacizumab., Methods: Totals of 19 patients were treated with intravitreal aflibercept, 19 with ranibizumab, and 18 with bevacizumab. The cytokine levels were measured by ELISA just before the injection, and 7 days and 1 month thereafter. Age- and sex-matched participants (n = 22) served as controls., Results: The median PlGF plasma concentration at baseline was <12.0 pg/mL in the control group as well as in all three anti-VEGF treatment cohorts. After intravitreal aflibercept injection, a significant upregulation of systemic PlGF could be observed in all treated patients (38.0 [31.0-44.0] pg/mL after 1 week [P < 0.001] and 16.0 [0.0-19.0] pg/mL [P = 0.005] after 4 weeks). No significant effects on plasma PlGF concentrations could be detected in those treated with ranibizumab and bevacizumab. The systemic VEGF-A levels were significantly reduced 1 and 4 weeks after intravitreal aflibercept (P < 0.001, P < 0.001) and bevacizumab (P < 0.001, P < 0.01) injections. No significant effects on plasma cytokine concentrations could be observed in the ranibizumab cohort. No significant effects on systemic VEGF-B could be observed in any of the treatment groups., Conclusions: In this study, we report a significant systemic upregulation of the proangiogenic cytokine PlGF after intravitreal administration of aflibercept. This might represent a counter-regulatory response to antiangiogenic therapy.

- Abstract
Objectives: The objective of this study was to investigate the occurrence of disability pensions over time among workers with physically demanding jobs., Methods: The occurrence of disability pension was prospectively studied between 1980-2008 among 325 549 Swedish construction workers. The risks for disability pension and years lost of working life were compared among 22 occupational groups, adjusting for age, body mass index, height, and smoking habits., Results: The risk varied considerably among blue-collar workers. For example, rock workers had double the risk of disability pension [relative risk (RR) 2.16, 95% confidence interval (95% CI) 1.96-2.39] compared to electricians. Most working years lost due to disability pensions (about 75%) were found among men >50 years, mainly due to musculoskeletal and cardiovascular diseases. The years of working life lost due to disability pension varied from 0.7 (salaried employees) to 3.2 years (rock workers) among occupational groups., Conclusion: Work environment is an important predictor for disability pension among construction workers with those in physically heavy jobs having the highest burden of disability. If the purpose is to increase labor force participation for workers with heavy jobs, strategies to reduce physical demands at work among elderly workers are important.

25. Analysis of structurally sensitive loss in GaN-based VCSEL cavities and its effect on modal discrimination.

- Abstract
Lateral loss causes optical energy to leave the laser cavity in the transverse, lateral, direction, and is sometimes neglected to simplify the numerical simulations. However, in contrast to outcoupling and absorption losses, we show that the lateral loss can change drastically with only nanometer-sized changes of the cavity structure, from being virtually zero to becoming the major source of cavity loss, since the cavity becomes antiguiding. This can be explained as the opening of a channel of efficient resonant lateral leakage of optical power at a certain oblique propagation angle. A number of different realizations of current apertures and top mirror designs in GaN-based VCSEL cavities, which have been suggested for realization of microcavity lasers emitting in the blue wavelength range, are simulated. Many of these are shown to lead to unintentional antiguiding, which can more than double the threshold gain for lasing. Notably, for strong enough antiguiding the resonant lateral leakage decreases so that the threshold gain values might again be tolerable. This regime has been suggested for robust single-mode operation since earlier predictions, building on analogies with slab waveguides, hinted at a very strong suppression of higher order modes. However, our simulations indicate that for the VCSEL cavities the derived formulas grossly overestimate the modal discrimination.

- Abstract
Objectives: The aim of this study was to get insight into the role of poor health, unhealthy behaviors, and unfavorable work characteristics on exit from paid employment due to disability pension, unemployment, and early retirement among older workers., Methods: Respondents of the longitudinal Survey of Health, Ageing, and Retirement in Europe (SHARE) in 11 European countries were selected when (i) aged between 50 years and the country-specific retirement age, (ii) in paid employment at baseline, and (iii) having information on employment status during the 4-year follow-up period (N=4923). Self-perceived health, health behaviors, and physical and psychosocial work characteristics were measured by interview at baseline. Employment status was derived from follow-up interviews after two and four years. Cox proportional hazards regression analyses were used to identify determinants of unemployment, disability pension, and early retirement., Results: Poor health was a risk factor for disability pension [hazard ratio (HR) 3.90, 95% confidence interval (95% CI) 2.51-6.05], and a lack of physical activity was a risk factor for disability pension (HR 3.05, 95% CI 1.68-5.55) and unemployment (HR 1.84, 95% CI 1.13-3.01). A lack of job control was a risk factor for disability pension, unemployment, and early retirement (HR 1.30-1.77)., Conclusions: Poor health, a lack of physical activity, and a lack of job control played a role in exit from paid employment, but their relative importance differed by pathway of labor force exit. Primary preventive interventions focusing on promoting physical activity as well as increasing job control may contribute to reducing premature exit from paid employment.

- Abstract
The study analyses whether and to what degree specific routes into retirement affect older people, i.e. the relationship between heterogeneous exit patterns and post-retirement health and wellbeing. We used longitudinal data from two points in time; data related to t
0 were collected in 1993, 1994, 1995 and 1996 and data related to t1 were collected in 2002 and 2003 ( N = 589). We focused on older people (55+ at t1 ) who were employed at t0 and retired at t1 . We used confirmative factor analysis to identify identical measures of health and wellbeing at both t0 and t1 . Hence, we were able to control for pre-retirement health and wellbeing when evaluating the effects of different exit routes. These routes were defined as dependence on incomes from sickness benefit, disability pension, part-time pension, unemployment insurance and active labour market programmes. Our initial structural equation model showed a clear relation between exit routes and post-retirement wellbeing. People who prior to retirement were pushed into social benefit programmes related to health and unemployment were significantly worse off as retirees, especially those with health-related benefits. However, these relationships disappeared once pre-retirement wellbeing was added to the model. Our main conclusion is that post-retirement wellbeing first and foremost is a consequence of accumulation of advantages and disadvantages during the life course. Both labour market exit routes and post-retirement wellbeing can be seen as outcomes of this process. There are no independent effects of the retirement process. Judging from our findings, there is no reason to believe that involvement in social security programmes allowing early retirement on health grounds has any additional negative consequences for health and wellbeing.- Published
