Abstract
This study aimed to analyze the clinical significance of signal shadowing during intraoperative optical coherence tomography (iOCT)-assisted vitreoretinal surgery caused by vitreoretinal instruments, tissue dyes, and vitreous substitutes, and to objectively quantify its impact on iOCT imaging. This is a retrospective observational study of postoperative image analysis from one hundred seventeen (117) patients who underwent iOCT-assisted vitrectomy. The image data were divided into three groups: vitreoretinal instruments, tissue dyes, and vitreous substitutes. The data was then processed using graphic software to measure the grade of picture quality distortion and compared to paired image controls without clinically perceptive interference, then analyzed statistically. The intraocular portion of all studied vitreoretinal instruments caused a high average gray level interference compared to controls ranging from 32 to 68% reduction, obscuring the area of interest significantly. The tips of the instruments produced low-grade shadowing, allowing the underlying tissue to be distinguished. The analyzed dyes demonstrated a wide interference range: ICG (- 75.12%), and triamcinolone (- 26.13%) showed dose-dependent high shadowing, while VITREODYNE™ (49.3%) and brilliant blue G (14.06%) exhibited no perceived distortions whilst increasing average gray levels. All analyzed vitreous substitutes (air, SF6, C3F8, PFCL, and silicone oil) showed an insignificant shadowing effect on iOCT. Certain dyes and vitreous substitutes produce a negligible shadowing effect compared to controls and other dyes, providing an advantage during real-time iOCT imaging. All analyzed vitreoretinal instruments showed a significant interference that should prompt the development of new imaging techniques or the implementation of materials with low-grade interference to overcome a clinically relevant shadowing effect on iOCT, maximizing the technology's visual accuracy and surgical diagnostic aid proficiency.

Abstract
PURPOSE To derive a Delphi method-based consensus for the surgical management of Full Thickness Macular Hole (FTMH) and Lamellar Macular Hole (LMH). METHODS 37 expert VR surgeons from 21 mainly European countries participated in Delphi method-based questionnaire for diagnosis and treatment of FTMHs and LMHs. RESULTS A total of 36 items were rated in round 1 by 37 participants, of which 10 items achieved consensus: intraoperative verification of PVD; clinical superiority of OCT-based FTMH classification; practical ineffectiveness of ocriplasmin; circular 360° ILM peeling for small macular holes; use of regular surgical technique for the size of the hole in concomitant retinal detachment; performing complete vitrectomy; SF6 gas as preferred tamponade; cataract surgery if crystalline lens is mildly/moderately opaque; removal of both ILM and LHEP in LMH surgery. In round 2, 18 items with moderate consensus (45-70% agreement) in round 1 were rated by 35 participants. Final consensus was reached in 35% of questions related to both diagnosis and surgical procedures. CONCLUSIONS This Delphi study provides valuable information about the consensus/disagreement on different scenarios encountered during FTMH and LMH management as a guide tosurgical decision-making. High rate of disagreement and/or variable approaches still exist for treating such relatively common conditions.

Abstract
The structure of the vitreous body, its interaction with the retinal surface and tractive alterations of the vitreoretinal interface may play a role in the pathogenesis and the development of age-related macular degeneration (AMD). From clinical trials it can be concluded that posterior vitreous detachment (PVD) or vitreous removal may protect against the development of neovascular AMD. Vitreomacular adhesions may promote neovascular AMD and may have an impact on the efficacy and frequency of intravitreal vascular endothelial growth factor (VEGF) inhibition. Therefore, vitreomacular surgery may be considered as a treatment option in selected cases. Peeling of epimacular membranes and the internal limiting membrane (ILM) may contribute to stabilizing visual acuity and reducing the treatment burden of current intravitreal pharmacotherapy. At present, surgical interventions in AMD are mainly performed in cases of submacular hemorrhage involving the fovea. The treatment is not standardized and consists of liquefaction of the blood using recombinant tissue plasminogen activator (rTPA) and its pneumatic displacement, potentially combined with VEGF inhibition. Other submacular surgical strategies, such as choroidal neovascularization (CNV) extraction, macular translocation or transplantation of retinal pigment epithelium (RPE) are currently limited to selected cases as a salvage treatment; however, the development of these submacular surgical interventions has formed the basis for new approaches in the treatment of dry and neovascular AMD including submacular or intravitreal gene and stem cell therapy.

Abstract
Age-related changes in vitreous molecular and anatomic morphology begin early in life and involve two major processes: vitreous liquefaction and weakening of vitreo-retinal adhesion. An imbalance in these two processes results in anomalous posterior vitreous detachment (PVD), which comprises, among other conditions, vitreo-macular adhesion (VMA) and traction (VMT). VMA is more common in patients with neovascular age-related macular degeneration (nAMD) than age-matched control patients, with the site of posterior vitreous adherence to the inner retina correlating with location of neovascular complexes. The pernicious effects of an attached posterior vitreous on age-related macular degeneration (AMD) progression involve mechanical forces, enhanced fluid influx and inflammation in and between the retinal layers, hypoxia leading to an accumulation of vascular endothelial growth factor (VEGF) and other stimulatory cytokines, and probably an infiltration of hyalocytes. It has been shown that vitrectomy not only mitigates progression to end-stage AMD, but existing choroidal neovascularization regresses after surgery. Thus, surgical PVD induction during vitrectomy or by pharmacologic vitreolysis may be considered in non-responders to anti-VEGF treatment with concomitant VMA.

Abstract
BACKGROUND Intravitreal anti-vascular endothelial growth factor (VEGF) is the standard treatment for exudative age-related macular degeneration (AMD). The constitution of the vitreomacular interface varies greatly in cases of attached (with or without traction) or detached vitreous body, which can impact the effectiveness of the anti-VEGF treatment. OBJECTIVE Based on the current literature this article displays the current state of the science on whether the constitution of the vitreous body has an effect on the anti-VEGF treatment. MATERIAL AND METHODS The published data extracted from current trials and post hoc analyses concerning this topic are presented and put into the clinical context. RESULTS The presence of a vitreomacular adhesion reduces the efficacy of anti-VEGF treatment of exudative AMD. Posterior vitreous body detachment represents a positive prognostic factor concerning the efficacy of anti-VEGF treatment but not necessarily the prognosis for visual acuity. CONCLUSION Patients with attached vitreous body need a more intensive treatment monitoring compared to patients with detached vitreous body. Therefore, in eyes with initial posterior vitreous body detachment receiving a treat and extend regimen, the interval between anti-VEGF injections can be extended to 4 instead of 2 weeks without endangering the success of treatment.

Abstract
Background Since the beginning of the Coronavirus disease 2019 (COVID-19) pandemic, there have been obstacles in the proper diagnosis and management of many diseases. We evaluated the changes in retinal detachment (RD) presentation and surgery during the COVID-19 pandemic and propose solutions to minimize the detrimental effects of lockdown on RD diagnosis. Materials and methods PubMed, Embase, Scopus, Web of Science, and Google Scholar were searched for relevant articles with the keywords “Retinal detachment” AND “Coronavirus OR COVID-19 OR SARS OR MERS.” Results The COVID-19 lockdown was associated a 53–66% reduction in RD presentation. The decrease in the rate of macula-on RD, the increase in the mean duration of symptoms, and the rise in the number of patients with proliferative vitreoretinopathy were all suggestive of a delayed presentation of RD. Moreover, a drop of 56–62% in RD repair surgeries was observed. However, the most frequently performed ophthalmic surgery changed from cataract surgery in April 2019 to RD repair in April 2020. Using phacovitrectomy instead of vitrectomy alone can reduce the number of operations in ophthalmology centers, decrease the use of personal protective equipment by 50%, and cut costs per patient by 17–20%. Also, developing a well-organized telemedicine system can decrease unnecessary visits and delayed presentations. Conclusion Delay in RD presentation and surgery is associated with a poorer prognosis. Optimizing the guidelines of RD management and developing a well-organized telemedicine system can minimize the impact of lockdown on RD management.

Abstract
Purpose To study the efficacy of a novel needle for intravitreal injection (IVI) in comparison to the conventional needle under experimental conditions. Methods The newly designed 30-gauge (G) needle (NDN) (EP 18158 542.3, patent pending) with occluded outer orifice and a side port for drug delivery was compared to the conventional standard hypodermic 30 G needle for IVI (SHN). An animal study to obtain needle tip aspirates was performed on 10 albino rat eyes. During IVIs, cellular content, which was cut by the needle tip, was aspirated. Cellular material was studied in regard to cell types and their quantity. The injection stream was studied using trypan blue dye in vitro and pig cadaver eyes. The penetration force was tested on polyurethane Testing Foil Strips PU 04 (Melab, Leonberg, Germany) by applying a velocity of 100 mm/min. The results were analyzed using descriptive statistics, correlation matrices and t-test methods with p<0.05 as statistically significant. Results Cytological analysis of the needle aspirates showed the presence of cellular content in each case. The amount of conjunctival, ciliary body epithelial cells and granulated basophilic protein sediments (sign of cellular damage) in the case of the NDN tips was significantly lower compared to the SHN. The average penetration force of the NDN was 0.791 N, and in the case of the SHN was 0.566 N. The injection stream study revealed a difference in the initial injection phase between the two needle types, although the diffuse filling of the vitreous area which surrounded the needle tip appeared to be similar. Discussion The NDN demonstrated superior performance with regard to a significantly reduced number of cells being captured by the needle tip. Delivery of the injected fluid into the vitreous cavity was comparable. In order to investigate superior properties of the NDN needle design, further studies with improved prototypes would be necessary.

Abstract
Biometric technologies have become the main focus in the design of state-of-the-art border security solutions. While respective research in the field of multimedia vision has been centred around improving quality and accuracy of identity recognition, the impact of such technologies upon society and legal regulations still remains a topic unaddressed, specifically within the engineering community. Research in technology can and in some respect must include collaboration with social sciences and social practice. Building on participation in the EU funded research project PERSONA [18] (Privacy, Ethical, Regulatory and SOcial No-gate crossing point solutions Acceptance), authors of this paper look at the challenges associated with biometrics-based solutions in no-gate border crossing point scenarios. This included the procedures needed for the assessment of their social, ethical, privacy and regulatory acceptance, particularly in view of the impact on both, the passengers and border control authorities as well as the potential pitfalls of biometric technology due to fraudulent activities. In consultation with the collaborating border control authorities, the paper reports on the formal assessment of biometric technologies for real-world acceptance to cope with the increasing demand of global travellers crossing state borders.

Abstract
Photodynamic therapy (PDT) uses photosensitive substance to provoke a cytotoxic reaction causing a cell damage or cell death. The substances, photosensitizers, are usually derivates of porphyrine or phtalocyanine. Photosensitizers must be activated by light in order to produce reactive oxygen species, mainly singlet oxygen. Sonodynamic therapy (SDT) utilizes ultrasound to enhance a cytotoxic effects of compounds called sonosensitizers. In this study we investigated photodynamic and sonodynamic effect of chloraluminium phtalocyanine disulfonate (ClAlPcS(2)) on HeLa cells. DNA damage, cell viability and reactive oxygen species (ROS) production were assessed to find whether the combination of PDT and SDT inflicts HeLa cells more than PDT alone. We found that the combined therapy increases DNA fragmentation, enhances ROS production and decreases cell survival. Our results indicate that ClAlPcS(2) can act as a sonosentitiser and combined with PDT causes more irreversible changes to the cells resulting in cell death than PDT alone.

Abstract
BACKGROUND Rhegmatogenous retinal detachment (RRD) is a separation of neurosensory retina from the underlying retinal pigment epithelium. It is caused by retinal tears, which let fluid pass from the vitreous cavity to the subretinal space. Pars plana vitrectomy (PPV), scleral buckling surgery and pneumatic retinopexy are three accepted management strategies whose efficacy remains controversial. Pneumatic retinopexy is considered in a separate Cochrane Review. OBJECTIVES The primary objective of this review was to assess the efficacy of PPV versus scleral buckling for the treatment of simple RRD (primary RRD of any extension with up to two clock hours large break(s) regardless of their anterior/posterior localisation) in people with (phakia) or without (aphakia) a natural lens in the eye, or with an artificial lens (pseudophakia). A secondary objective was to assess any data on economic and quality-of-life measures. SEARCH METHODS We searched CENTRAL, which contains the Cochrane Eyes and Vision Trials Register; MEDLINE; Embase; LILACS; the ISRCTN registry; ClinicalTrials.gov and the WHO ICTRP. The date of the search was 5 December 2018. SELECTION CRITERIA We included randomised controlled trials (RCTs) comparing PPV versus scleral buckling surgery with at least three months of follow-up. DATA COLLECTION AND ANALYSIS We used standard Cochrane methodology. Two review authors independently extracted the data and study characteristics from the studies identified as eligible after initial screening. We considered the following outcomes: primary retinal reattachment, postoperative visual acuity, final anatomical success, recurrence of retinal detachment, number of interventions needed to achieve final anatomical success, quality of life and adverse effects. We assessed the certainty of evidence using GRADE. MAIN RESULTS This review included 10 RCTs (1307 eyes of 1307 participants) from Europe, India, Iran, Japan and Mexico, which compared PPV and scleral buckling for RRD repair. Two of these 10 studies compared PPV combined with scleral buckling with scleral buckling alone (54 participants). All studies were high or unclear risk of bias on at least one domain. Five studies were funded by non-commercial sources, while the other five studies did not report source of funding.There was little or no difference in the proportion of participants who achieved retinal reattachment at least 3 months after the operation in the PPV group compared to those in the scleral buckling group (risk ratio (RR) 1.07, 95% confidence intervals (CI) 0.98 to 1.16; 9 RCTs, 1261 participants, low-certainty evidence). Approximately 67 in every 100 people treated with scleral buckling had retinal reattachment by 3 to 12 months. Treatment with PPV may result in 4 more people with retinal reattachment in every 100 people treated (95% confidence interval (CI) 2 fewer to 11 more).There was no evidence of any important difference in postoperative visual acuity between participants in the PPV group compared to those in the scleral buckling group (mean difference (MD) 0.00 logMAR, 95% CI -0.09 to 0.10, 6 RCTs, 1138 participants, low-certainty evidence).There was little or no difference in final anatomical success between participants in the PPV group and scleral buckling group (RR 1.01, 95% CI 0.99 to 1.04, 9 RCTs, 1235 participants, low-certainty evidence). There were 94 out of 100 people treated with control (scleral buckling) that achieved final anatomical success compared to 96 out of 100 in the PPV group.Retinal redetachment was reported in fewer participants in the PPV group compared to the scleral buckling group (RR 0.75 (95% CI 0.59 to 0.96, 9 RCTs, 1320 participants, low-certainty evidence). Approximately 28 in every 100 people treated with scleral buckling had retinal detachment by 3 to 36 months. Treatment with PPV may result in seven fewer people with retinal detachment in every 100 people treated (95% CI 1 to 11 fewer).Participants treated with PPV on average needed fewer interventions to achieve final anatomical success but the difference was small and data were skewed (MD -0.20, 95% CI -0.34 to -0.06, 2 RCTs, 682 participants, very low-certainty evidence).Very low-certainty evidence on quality of life suggested that more people in the PPV group were "satisfied with vision" compared with the scleral buckling group (RR 6.22, 95% CI 0.88 to 44.09, 1 RCT, 32 participants).All included studies reported adverse effects, however, it was not always clear whether they were reported as number of participants or number of adverse effects. Cataract development or progression was more prevalent in the PPV group (RR 1.71, 95% CI 1.45 to 2.01), choroidal detachment was more prevalent in the scleral buckling group (RR 0.19, 95% CI 0.06 to 0.65) and new/iatrogenic breaks were observed only in the PPV group (RR 8.21, 95% CI 1.91 to 35.21). Estimates of the relative frequency of other adverse effects, including postoperative proliferative vitreoretinopathy, postoperative increase in intraocular pressure, development of cystoid macular oedema, macular pucker and strabismus were imprecise. Evidence for adverse effects was low-certainty evidence. AUTHORS' CONCLUSIONS Low- or very low-certainty evidence indicates that there may be little or no difference between PPV and scleral buckling in terms of primary success rate, visual acuity gain and final anatomical success in treating primary RRD. Low-certainty evidence suggests that there may be less retinal redetachment in the PPV group. Some adverse events appeared to be more common in the PPV group, such as cataract progression and new iatrogenic breaks, whereas others were more commonly seen in the scleral buckling group such as choroidal detachment.

Abstract
PURPOSE To assess the position of intraocular lenses (IOLs) at the end of standard phacoemulsification with intraoperative spectral-domain optical coherence tomography (SD-OCT). SETTINGS Department of Ophthalmology, Rudolf Foundation Hospital, Vienna, Austria. DESIGN Prospective case series. METHODS Standard phacoemulsification with IOL implantation was performed. The Rescan 700 SD-OCT system was used for intraoperative imaging. The anterior segment of the eye was scanned using SD-OCT at the end of the surgery. The distance from the IOL optic center and the IOL optic edge to the posterior capsule was measured postoperatively using graphic software. RESULTS The study comprised 74 patients (101 eyes). The mean axial length was 23.97 mm (range 21.43 to 28.61 mm). The mean IOL power was 20.39 diopters (D) (range 6.5 to 27.5 D). Contact between the IOL and posterior capsule was absent in 88 cases (87.13%), and partial or full contact was present in 13 cases (12.87%). The mean distance between the IOL central optic and posterior capsule was 0.71 pixel (range 0.06 to 1.38 pixels) in 99 cases (98.02%). In 42 cases (57.53%), partial contact between the IOL edges and the posterior capsule was noticed. The mean distance between the IOL edge and posterior capsule was 0.21 pixel (range 0.04 to 0.92 pixel). CONCLUSIONS Intraoperative SD-OCT facilitated the imaging of IOL position during standard phacoemulsification. Contact between the IOL central optic and posterior capsule at the end of the surgery occurred rarely. Improved IOL design should be considered. FINANCIAL DISCLOSURE Drs.

Abstract
Zusammenfassung
Hintergrund
Durch die Einführung der Pars plana Vitrektomie ist eine Vielzahl von vitreoretinalen Erkrankungen behandelbar geworden. Kontinuierliche Verbesserungen der Geräte, Instrumente und zusätzliche Hilfsmittel sowie neue Techniken kennzeichnen den enormen Fortschritt der vitreoretinalen Chirurgie.
Methoden
In einer Literaturübersicht werden die Operationstechniken verschiedenster vitreoretinaler Eingriffe analysiert. Sofern aufgrund aktueller Entwicklungen verschiedene Optionen in der Operationstechnik bestehen, werden Experten auf dem Gebiet der vitreoretinalen Chirurgie über ihre Erfahrung und ihre Empfehlung befragt.
Ergebnisse
Die 20 Gauge Pars plana Vitrektomie wurde größtenteils durch die Verwendung von Trokaren (23, 25 und 27 Gauge) mit entsprechenden Instrumenten mit kleinerem Durchmesser abgelöst. Die Pars plana Vitrektomie ist nahtlos möglich, trotzdem kann es notwendig sein, eine zusätzliche Sicherung der Wunde mit einer Naht durchzuführen, um Leckage und Hypotonie zu vermeiden. Die Visualisierung des Glaskörpers erfolgt zunehmend mit Triamcinolon, epiretinale Gliosen und die Membrana limitans interna werden routinemäßig mit Vitalfarbstoffen dargestellt. Bei der Operationstechnik beim Makulaforamen und bei der Ablatio retinae zeigen sich sowohl bei aktuellen Publikationen als auch unter den Experten Variationen.
Schlussfolgerungen
Die Pars plana Vitrektomie hat sich aufgrund der Weiterentwicklung speziell im Bereich der Trokar Systeme, Vitrektome, der Weitwinkel-Beobachtungssysteme sowie dank neuer Techniken zu einer essentiellen OP-Methode für ein weites Indikationsspektrum entwickelt. Dies ist die Basis der Behandlung verschiedenster vitreoretinaler Erkrankungen mit immer weniger Operationstrauma, weniger intraoperativen und postoperativen Komplikationen und gutem Therapieerfolg. Unterschiedliche Operationsvarianten, neue Techniken und die Weiterentwicklung der Geräte und Instrumente sind die Basis für einen auch zukünftigen Fortschritt der Pars plana Vitrektomie.

Abstract
BACKGROUND The pathogenesis of non-rhegmatogenous retinal detachment (non-RRD) associated with morning glory syndrome (MGS) is not established, as well as best surgical approach to treat RD. Our purpose was to analyse intraoperative optical coherence tomography data (iOCT) in all steps of pars plana vitrectomy (PPV) for non-RRD in MGS, in order to follow pathophysiological aspects of the disease and to understand the tissues behaviour during surgical workflow. CASE PRESENTATION Intraoperative spectral domain optical coherent tomography (iSD-OCT) assisted PPV using Rescan 700 (Carl Zeiss Meditech, Jena, Germany) with epiretinal membrane (ERM) and internal retinal membrane (ILM) peeling, and air endotamponade was performed on the only eye of a 21 years old female with non-RRD associated with MGS. BCVA, pre-, intra- and postoperative OCT were performed along with standard ocular examination. iOCT video and snapshots were analysed intra- and postoperatively using post-processing approach using graphic software. The progression of non-RRD resulted in best corrected visual acuity (BCVA) decrease from 0.8 to 0.2. Triamcinolone enhanced iOCT imaging revealed strong vitreous traction and adhesion above the macula and optic disc. Internal limiting membrane was peeled under iOCT control to prevent the peeling of inner layers of the retinal schisis. No retinal break was detected, and only air endotamponade was performed. The retina reattached during first 4 weeks of follow-up with gradual resolution of intraretinal- and subretinal fluid, and remained stable in 12 months. BCVA improved to 0.8. CONCLUSION Based on iSD-OCT findings we assume that non-RRD in this case of MGS is caused primarily by the vitreous traction with further possible formation of the retinal breaks. Retinal reattachment reached only with air endotamponade strongly advocates the tractional component of non-RRD and retinal schisis assotiated with MGS. Early PPV for central non-RRD and retinal schisis with the use of iOCT can be performed in more safe and controlled manner and has to be considered to reduce the risk of retinal break formation and to prevent the central vision loss.

Abstract
PURPOSE The surgery of choice for primary retinal detachment (RD) has shifted towards primary vitrectomy (PPV) in recent years. In this study, 2 cohorts of consecutive patients, treated by 8 retinal surgeons within a 7-year time span were compared. METHODS Baseline demographic data, surgical procedure, and outcome of patients with primary RD surgery between January 2007 and December 2008 (group 1, G1) and January 2012 and December 2013 (group 2, G2) were compared. Statistical analysis included univariate comparisons (Wilcoxon rank-sum test and χ2 test) and ANCOVA (analysis of covariance) models. RESULTS The most common primary procedure was scleral buckling (n = 92, 66%) in G1 and PPV (n = 252, 85%) in G2 (p < 0.0001). Primary anatomical success rates were comparable (89%). The percentage of eyes with best corrected visual acuity (BCVA) equal or better than 0.3 logMAR (6/12) at final follow-up was significantly higher in G2 (61%, n = 156) compared to 49% (n = 68) in G1 (p = 0.0223). CONCLUSIONS Within 7 years, a complete trend reversal could be observed shifting the primary surgical approach for RD towards PPV. Primary and final anatomical success rates were comparable, yet the later group experienced a significantly higher gain in BCVA, which approves the change in treatment regimen.

Abstract
BACKGROUND AND OBJECTIVE A retrospective, single-center case-series was initiated to evaluate initial clinical experience with the first commercially available intraoperative optical coherence tomography system (iOCT). PATIENTS AND METHODS The Rescan 700 iOCT (Zeiss, Oberkochen, Germany), a spectral-domain OCT system integrated into a surgical microscope, was used in 40 consecutive cases. A standardized review was used to assess whether iOCT imaging resulted in additional information and/or altered decision-making. RESULTS The iOCT system was usable in conjunction with common chromovitrectomy dyes and tamponades. The surgeons reported that iOCT imaging provided additional information in 74.1% of the posterior and combined surgical cases, which resulted in altered decision-making in 41.9% of the cases. The iOCT imaging time, on average, amounted to 167 seconds. In anterior procedures, the surgeons reported gaining additional information in 22.2% of all cases, but no cases of altered decision-making were reported. Hereby, the iOCT imaging time amounted to 117 seconds, on average. CONCLUSION The demonstrated results suggest iOCT has the potential to improve the quality of posterior and anterior segment surgery.

Abstract
PurposeTo evaluate the results of indocyanine green angiography (ICGA)-guided verteporfin photodynamic therapy (PDT) with half-fluence rate combined with intravitreal application of anti-VEGF in treating choroidal neovascularization (CNV) in chronic central serous chorioretinopathy (CSCR).Patients and methodsIn this retrospective cohort study 17 consecutive patients with secondary CNV due to chronic CSCR had their diagnosis verified with fluorescein angiography (FA) and ICGA at baseline. All eyes received either intravitreal ranibizumab (IVR) or bevacizumab (IVB). On the consecutive day following the initial IVR/IVB treatment, ICGA-guided verteporfin (6 mg/m(2)) PDT with half-fluence rate (25 J/cm(2)) was performed on every patient. IVR or IVB was rescheduled on a pro re nata regimen. Main outcome measures were changes in visual acuity (VA) according to the ETDRS letter score and changes in the central foveal thickness (CFT).ResultsBest-corrected VA at baseline was 65.6 letters (±6.7; n=17) according to the ETDRS letter score. At 12 months, mean ETDRS letter score improved to 71.2 letters (P=0.34). CFT was 309 μm and decreased to 216 μm at month 12 control (P=0.0004). Nine eyes (52.9%) received additional treatment with IVR/IVB due to recurrence of subretinal fluid, with an overall mean number of IVR/IVB treatment of 1.8±3.6 per patient with no systemic side effects during 12 months' follow-up.ConclusionsIVR or IVB combined with ICGA-guided half-fluence PDT with verteporfin is effective in treating CNV in chronic CSCR, with choroidal hyperpermeability in ICGA, resulting in stable vision and significant reduction of CFT.

Abstract
PURPOSE To evaluate the influence of the needle size used for intravitreal (IVT) injections on patients' pain experience in a randomized, double-armed, single-blinded, clinical trial. METHODS Patients included were randomized to have an IVT injection performed with a 27-gauge needle (group 1) or with a 30-gauge needle (group 2). The topical anaesthesia before the injection was standardized. Immediately after the injection, patients were asked to grade their pain using the visual analogue scale (VAS) and the Wong-Baker FACES scale. The main outcome measure was the pain score assessment. Cofactors analysed were patients' demographics (age and gender) and clinical characteristics (such as the number of previous IVT injections). In addition, scaled surgeon's questionnaires to assess the IVT injection procedure were evaluated. For statistical analysis, a regression model was used. RESULTS The data of 208 patients (group 1: 104 patients; group 2: 104 patients) were analysed. There was no significant difference in the VAS pain scores (p > 0.18) and in the Wong-Baker pain scores (p > 0.59) between both treatment groups. Gender (p = 0.0288) and the number of previous IVT injections (p = 0.0028) significantly influenced the VAS pain scores (p < 0.05). Female patients and patients with a history of previous IVT injections had higher pain scores. The surgeon's questionnaire showed an overall preference towards the use of a 30-gauge needle for IVT injections. CONCLUSION The use of a 30-gauge needle for IVT injections showed no significant effect in pain relief compared to the use of a 27-gauge needle. However, a 30-gauge needle was preferred by all surgeons.

Abstract
PURPOSE Previous studies have indicated that the immune system is involved in the pathogenesis of the AMD. Increased visceral fat, in addition, has a pro-inflammatory effect on the organism by producing or influencing different kinds of inflammatory factors. The aim of this study is to determine the relationship of body fat distribution in patients with age-related macula degeneration in comparison to a control group in the Austrian population. METHODS In this case-control study, body weight and height, and body mass index (BMI) were measured for each subject in 54 patients with exudative AMD and compared to 46 gender- and age-matched healthy control subjects. Body composition and abdominal fat areas were measured using dual-energy X-ray absorptiometry (DEXA). Data on age, gender distribution, smoking history and systemic diseases, respectively, were compared. The inflammatory markers CRP, tumour necrosis factor-alpha (TNF-alpha), leptin, amyloid A, amyloid beta and interleukin-6 (IL-6) were assayed by ELISA (R&D). RESULTS DEXA revealed central-abdominal-to-total body fat ratio of 0.073 +/- 0.011 in AMD patients compared to 0.061 +/- 0.013 in the controls (p <0.001; d = 0.98). The calculation of BMI has provided a significant result (p =0.045). U-test results for Aß1-42, IL-6, SAA and CRP each were significant (p < 0.05), with higher values in AMD patients. Leptin, TNF-alpha and Aß1-40 showed no significant differences between the groups. CONCLUSION Our results suggest that abdominal fat distribution is significantly associated with age-related macular degeneration. Analysis of patients with exudative AMD revealed higher levels of CRP, amyloid ß1-42, IL-6 and amyloid alpha.

Abstract
PURPOSE To compare pars plana vitrectomy and 360° endolaser therapy with pars plana vitrectomy and an encircling scleral buckle for the treatment of primary rhegmatogenous retinal detachments in a randomized pilot study including 60 patients. METHODS Main outcome measures were single-surgery anatomic success rate and final best-corrected visual acuity at 6 months follow-up. Cofactors analysed were complication rates, patients' comfort, refractive outcome and macula status assessed using a spectral-domain optical coherence tomography. RESULTS With differences between both treatment groups regarding type of the retinal detachment, localization of retinal tears (p = 0.0085) and the choice of the intraocular tamponade (p < 0.0202), there were no significant differences between the single-surgery anatomic success rate (93.33% both groups, p = 1.0) and the visual acuity at final follow-up (≤0.3 logMAR [logarithm of minimum angle of resolution] in 66.67% in the endolaser group versus 40.0% in the scleral buckle group, p = 0.0514). Questionnaire responses showed lower levels of patients' discomfort in the endolaser group. A significant difference between both groups was found in the refractive error change after surgery (-0.20 ± 0.51 dioptres in the endolaser group versus -0.88 ± 0.88 dioptres in the scleral buckle group, p = 0.0003). CONCLUSION Primary vitrectomy combined with 360° endolaser therapy seems to be as effective as vitrectomy combined with an encircling scleral buckle in patients with rhegmatogenous retinal detachment, with possible benefits of an improved patients' comfort and a more stable refractive status after surgery.

Abstract
We present the first ab initio construction of valence-space Hamiltonians for medium-mass nuclei based on chiral two- and three-nucleon interactions using the in-medium similarity renormalization group. When applied to the oxygen isotopes, we find experimental ground-state energies are well reproduced, including the flat trend beyond the drip line at (24)O. Similarly, natural-parity spectra in (21,22,23,24)O are in agreement with experiment, and we present predictions for excited states in (25,26)O. The results exhibit a weak dependence on the harmonic-oscillator basis parameter and reproduce spectroscopy within the standard sd valence space.

Abstract
We study the electronic screening mechanisms of the effective Coulomb on-site repulsion in hole-doped Sr(14)Cu(24)O(41) compared to undoped La(6)Ca(8)Cu(24)O(41) using polarization dependent high-resolution resonant inelastic x-ray scattering at Cu M edges. By measuring the energy of the effective Coulomb on-site repulsion and the spin excitations, we estimate superexchange and hopping matrix element energies along rungs and legs, respectively. Interestingly, hole doping locally screens the Coulomb on-site repulsion reducing it by as much as 25%. We suggest that the increased ratio of the electronic kinetic to the electronic correlation energy contributes to the local superexchange mediated pairing between holes.

Abstract
PURPOSE To analyze choroidal, Sattler's, and Haller's layer thickness maps in age-related macular degeneration (AMD) patients having eyes with bilateral large drusen and pigment changes (intermediate AMD), in patients having intermediate AMD eyes with neovascular fellow eyes (nAMD), and in healthy subjects using three-dimensional (3D) 1060-nm optical coherence tomography (OCT). METHODS Automatically generated choroidal thickness (ChT), retinal thickness, and Sattler's and Haller's layer thickness maps were statistically analyzed in 67 subjects consisting of intermediate AMD (n = 21), intermediate AMD (n = 22) with fellow nAMD eyes (n = 22), and healthy eyes (n = 24) with no age and axial eye length difference between groups of eyes (P > 0.05, ANOVA). Eyes were imaged by a prototype high-speed (60,000 A-scans/s) spectral-domain 3D 1060-nm OCT over a 36° × 36° field of view. RESULTS The mean ± SD (μm) subfoveal ChT for healthy subjects and for bilateral intermediate AMD, unilateral intermediate AMD, and their nAMD fellow eyes was 259 ± 95 and 222 ± 98, 149 ± 60, and 171 ± 78, respectively. Choroidal thickness maps demonstrated significant submacular thinning in unilateral intermediate AMD in comparison to healthy and bilateral intermediate AMD eyes (P < 0.001, ANOVA, post hoc P < 0.001 and P < 0.05, respectively). Sattler's and Haller's layers were thinnest in intermediate AMDs that presented with nAMD fellow eyes (Kruskal-Wallis test P < 0.01). For the choroid and its sublayers, there was no difference between the intermediate AMD eyes and their fellow nAMD eyes (paired testing, P < 0.05). CONCLUSIONS The 3D 1060-nm OCT choroidal imaging visualized significant changes in choroidal, Sattler's, and Haller's layer thickness in relation to the progression of AMD. This may be important for understanding the choroidopathy in the pathophysiology of AMD.

Abstract
Objectives To examine the feasibility of automatically segmented choroidal vessels in three-dimensional (3D) 1060-nmOCT by testing repeatability in healthy and AMD eyes and by mapping Haller's and Sattler's layer thickness in healthy eyes Methods Fifty-five eyes (from 45 healthy subjects and 10 with non-neovascular age-related macular degeneration (AMD) subjects) were imaged by 3D-1060-nmOCT over a 36°x36° field of view. Haller's and Sattler's layer were automatically segmented, mapped and averaged across the Early Treatment Diabetic Retinopathy Study grid. For ten AMD eyes and ten healthy eyes, imaging was repeated within the same session and on another day. Outcomes were the repeatability agreement of Haller's and Sattler's layer thicknesses in healthy and AMD eyes, the validation with ICGA and the statistical analysis of the effect of age and axial eye length (AL) on both healthy choroidalsublayers. Results The coefficients of repeatability for Sattler's and Haller's layers were 35% and 21% in healthy eyes and 44% and 31% in AMD eyes, respectively. The mean±SD healthy central submacular field thickness for Sattler's and Haller's was 87±56 µm and 141±50 µm, respectively, with a significant relationship for AL (P<.001). Conclusions Automated Sattler's and Haller's thickness segmentation generates rapid 3D measurements with a repeatability correspondingto reported manual segmentation. Sublayers in healthy eyes thinnedsignificantly with increasing AL. In the presence of the thinned Sattler's layer in AMD, careful measurement interpretation is needed. Automatic choroidal vascular layer mapping may help to explain if pathological choroidal thinning affects medium and large choroidal vasculature in addition to choriocapillaris loss.
