Retinal Layer Thinning After Optic Neuritis Is Associated With Future Relapse Remission in Relapsing Multiple Sclerosis
Retinal Layer Thinning After Optic Neuritis Is Associated With Future Relapse Remission in Relapsing Multiple Sclerosis
Remission of relapses is an important contributor to both short- and long-term prognosis in relapsing multiple sclerosis (RMS). In MS-associated acute optic neuritis (MS-ON), retinal layer thinning measured by optical coherence tomography (OCT) is a reliable biomarker of both functional recovery and the degree of neuroaxonal damage. However, prediction of non-ON relapse remission is challenging. We aimed to investigate whether retinal thinning after ON is associated with relapse remission after subsequent non-ON relapses.
Changes in Visual Function and Correlations with Inner Retinal Structure in Acute and Chronic Leber's Hereditary Optic Neuropathy Patients after Treatment with Idebenone
Changes in Visual Function and Correlations with Inner Retinal Structure in Acute and Chronic Leber's Hereditary Optic Neuropathy Patients after Treatment with Idebenone
Progressive impairment and degeneration of retinal ganglion cells (RGC) and nerve fibers in Leber's hereditary optic neuropathy (LHON) usually cause permanent visual loss. Idebenone is currently the only approved treatment. However, its therapeutic potential in different stages of LHON has not been definitely clarified. We aimed to investigate the changes in visual function and correlations with retinal structure in acute and in chronic LHON patients after treatment with idebenone. Twenty-three genetically confirmed LHON patients were followed during treatment using logMAR charts, automated perimetry and optical coherence tomography (OCT). Mean visual acuity improved significantly in acute patients treated within 1 year from onset (-0.52 ± 0.46 logMAR from nadir), in early chronic patients who started after 1-5 years (-0.39 ± 0.27 logMAR from baseline), and in late chronic patients with treatment initiation after >5 years (-0.33 ± 0.28 logMAR from baseline, < 0.001 all groups). In acute and in chronic patients, strong correlations between OCT and visual function parameters were present only after treatment. This and the sustained visual recovery after treatment may indicate a reactivated signal transduction in dysfunctional RGC that survive the acute phase. Our results support previous evidence that idebenone has therapeutic potential in promoting visual recovery in LHON.
Systematic ultrastructural comparison of swept-source and full-depth spectral domain optical coherence tomography imaging of diabetic macular oedema
Systematic ultrastructural comparison of swept-source and full-depth spectral domain optical coherence tomography imaging of diabetic macular oedema
Optical coherence tomography (OCT) is commonly used to diagnose and assess diabetic macular oedema (DME). Swept-source OCT (SS-OCT) promises improved imaging depth and more independence from media opacities. Heidelberg Spectralis full-depth imaging (FDI) combines details at different depths to one representation. The aim of this study was to determine the comparability of the imaging methods concerning DME ultrastructure.

Comparison of Spectralis and Cirrus spectral domain optical coherence tomography for the objective morphometric assessment of the neuroretinal rim width
Comparison of Spectralis and Cirrus spectral domain optical coherence tomography for the objective morphometric assessment of the neuroretinal rim width
The assessment of cup-disc ratio as a surrogate parameter for the neuroretinal rim width (NRW) of the optic nerve is well established, but prone to human error and imprecision. Objective assessment of the NRW is provided by spectral domain optical coherence tomography (SD-OCT). This study is the first to systematically compare NRW measurements acquired with the Carl Zeiss Meditech Cirrus HD-OCT 5000 and the Heidelberg Engineering Spectralis SD-OCT.

A comparison of the performance of the two OCT machines was made.
Early ultrasonographic tumor regression after linear accelerator stereotactic fractionated photon radiotherapy of choroidal melanoma as a predictor for metastatic spread
Early ultrasonographic tumor regression after linear accelerator stereotactic fractionated photon radiotherapy of choroidal melanoma as a predictor for metastatic spread
During extended follow-up (of up to 15 years), approximately fifty percent of patients with choroidal melanoma will develop metastatic disease and eventually die. Thus, continuing research on prognostic factors, early detection and treatment is necessary. Height regression rates both after plaque brachytherapy and proton beam irradiation have been shown to have prognostic value. The purpose of this study was to analyze the influence of early tumor regression rate after treatment of choroidal melanoma with LINAC stereotactic fractionated radiotherapy (SFRT) as an independent risk factor for metastasis.

Antivascular endothelial growth factors in age-related macular degeneration
Antivascular endothelial growth factors in age-related macular degeneration
Age-related macular degeneration (AMD) is the leading cause of irreversible vision loss in adults aged over 50 years in developed countries. Until recently, argon laser photocoagulation and photo-dynamic therapy (PDT) were the only treatments available for the neovascular form of AMD. The introduction of new intravitreally injectable inhibitors of vascular endothelial growth factor (VEGF) revolutionized the management of the wet form. Pegaptanib was the first anti-VEGF agent to be approved by the US Food and Drug Administration (FDA) for use in neovascular AMD. The VISION study showed that patients receiving pegaptanib lost vision in a smaller rate than those treated with conventional care. Bevacizumab is a full-length recombinant humanized monoclonal antibody which binds to all isoforms of VEGF-A. It is licensed for the intravenous administration for the treatment of malignant solid tumors and is available for off-label use in the treatment of AMD-related CNV. Numerous retrospective studies have shown beneficial effects of bevacizumab in patients with neovascular AMD. Ranibizumab is a recombinant, humanized antibody antigen-binding fragment (Fab) that binds to all known active forms of VEGF-A. The US FDA approved ranibizumab for treatment of all subtypes of choroidal neovascularization secondary to AMD. VEGF trap is a pharmacologically engineered protein that binds VEGF with higher affinity than pegaptanib or ranibizumab and thus prevents VEGF binding to its cellular receptor offering a theoretically longer interval between necessary treatments. A number of studies have shown that OCT imaging allows identification of functionally relevant factors like subretinal fluid or retinal thickness, which are important for the establishment of optimized individual dosing regimen during anti-angiogenesis therapies.
OphthalNet Vienna: constructive quality assurance and resource optimization in ophthalmology
OphthalNet Vienna: constructive quality assurance and resource optimization in ophthalmology
Significant improvements in the field of diagnostic methods and therapeutic options achieved during the last decade allow the early diagnosis, accurate follow-up and individual indication for the treatment with highly efficacious therapeutic agents in a wide range of ophthalmological pathologies. The burden on health care systems is extremely high, as treatment and diagnostic follow up has to be repeated in a regular manner. Whereas the treatment can only be applied in tertiary care centers (eye clinics), follow-up and management mainly depends on the OCT technology, which is becoming available at many field ophthalmologists' practices. This article describes the OphthalNet project, a network which optimizes collaboration between eye clinics and field ophthalmologists based on medical guidelines, workflow support and the future use of electronic infrastructure.
Connecting cloud-based personal health records with an XDS affinity domain to provide additional information at the point-of-care
Connecting cloud-based personal health records with an XDS affinity domain to provide additional information at the point-of-care
Due to the increasing use of Electronic Health Records by healthcare providers and the trend towards the use of Personal Health Records by patients the potential need to integrate these two types of medical documentation emerged. The introduction of the ELGA (Elektronische Gesundheitsakte, EHR) during the next few years is reason enough to propose possibilities to directly involve the patient into the data acquisition process in form of generating personal health data (e.g. vital signs, etc.) at home. In particular patients with chronic diseases will benefit from this integrated architecture. Furthermore, patients could archive all documents for their own use and responsibility. This article reviews literature about integration possibilities for personal and electronic health records and proposes an architecture which integrates data from patient-side into an affinity domains' XDS document repository.
Clinical Decision Support for the Classification of Diabetic Retinopathy: A Comparison of Manual and Automated Results
Clinical Decision Support for the Classification of Diabetic Retinopathy: A Comparison of Manual and Automated Results
The management of diabetic retinopathy, a frequent ophthalmological manifestation of diabetes mellitus, consists of regular examinations and a standardized, manual classification of disease severity, which is used to recommend re-examination intervals. To evaluate the feasibility and safety of implementing automated, guideline-based diabetic retinopathy (DR) grading into clinical routine by applying established clinical decision support (CDS) technology. We compared manual with automated classification that was generated using medical documentation and an Arden server with a specific medical logic module. Of 7169 included eyes, 47% (n=3373) showed inter-method classification agreement, specifically 29.4% in mild DR, 38.3% in moderate DR, 27.6% in severe DR, and 65.7% in proliferative DR. We demonstrate that the implementation of a CDS system for automated disease severity classification in diabetic retinopathy is feasible but also that, due to the highly individual nature of medical documentation, certain important criteria for the used electronic health record system need to be met in order to achieve reliable results.
