Long-term effects of doping with anabolic steroids during adolescence on physical and mental health.

BACKGROUND: Systematic doping programs like in the GDR were applied in adolescent competitive athletes to induce supramaximal athletic performance. The substances had adverse somatic and psychological effects. The psychological development of the young athletes was impaired and they suffered in adulthood from long-term effects and secondary diseases even years after the doping period. METHOD: The study compared three groups: competitive athletes with doping (I), competitive athletes without doping (II) and persons with no sports activities (III). Somatic and psychological diseases were analyzed to identify the adverse effects of doping in the most vulnerable phase of development in adolescence. Participants were asked to supply a patient history and completed a questionnaire with standardized psychological tests. RESULTS: The doping cohort had a higher rate of somatic diseases, psychological disorders and social and professional difficulties. The differences were gender-specific with males more often having impaired liver function, depression, tumors and difficulties associated with the workplace . The doping group reported more emotional and physical neglect during childhood. They proved to be less optimistic but more pessimistic, to perceive less social support and to be more depressive. The study identified less extraversion and more neuroticism. Posttraumatic stress disorder (PTSD) occurred in a small number of participants in the doping group. Doping is associated with psychiatric variables. Predictors were the subscale identifying feelings of the Toronto alexithymia scale 20 (TAS-20), the sense of coherence and the Beck depression inventory 2 (BDI-II) and the Beck depression inventory (BDI). CONCLUSION: Physical and psychosocial effects imply correlation with the application of doping substances but might not only be due to the side effects of these substances but also caused by the system, which exerts great psychological pressure and stress during adolescence, a highly vulnerable phase.

[Effect of low-dose PDT on perfusion of the choriocapillaris in cCSCR : An OCT-angiography-based study]. / Effekt der "low-dose PDT" auf die choriokapilläre Perfusion bei cCRCS : Eine OCT-Angiographie-gestützte Studie.

BACKGROUND: In patients with chronic central serous chorioretinopathy (cCSCR) it is assumed that low-dose photodynamic therapy (PDT) induces short-term hypoperfusion of the choriocapillaris, which leads to long-term choroidal vascular remodeling and subsequent reduction of vascular hyperpermeability and leakage; however, it remains unclear whether the hypoperfusion completely returns to normal. The main aim of the retrospective study was to analyze the choroidal flow signal after treatment with low-dose PDT by optical coherence tomography-angiography (OCT­A). PATIENTS AND METHODS: In this study 16 eyes with a total of 19 treated areas were included. Aside from visual acuity and metamorphopsia checks, all patients underwent enhanced depth imaging-OCT (EDI-OCT) and OCT­A in the areas treated with low-dose PDT. In the present study, the flow signal in the choriocapillaris and choroidal thickness were measured retrospectively both in the PDT-treated area and in a non-treated reference area located in close proximity with similar eccentricity to the center of the fovea. RESULTS: The study found a mean reduction of 33% (p < 0.001) of the choroidal flow signal in the treated area compared to the reference area and an average decrease in choroidal thickness of 71 µm (p = 0.001). In the long term 7 out of 10 patients suffered from metamorphopsia despite the low-dose PDT; however, visual acuity was improved in almost half of the patients by the treatment. CONCLUSION: Using OCT­A it could be shown that at the choriocapillaris level, hypoperfusion persists in spite of low-dose PDT. Thus, the choroidal vascular remodeling is not able to completely compensate for the hypoperfusion induced by thrombosis.

[Large macular hole-Always a poor prognosis?] / Großes Makulaforamen ­ immer eine schlechte Prognose?

BACKGROUND: Age, preoperative visual acuity and macular hole size have been reported to be prognostic markers for the postoperative outcome in patients with full thickness macular holes (FTMH). OBJECTIVE: A retrospective observational clinical study was performed in order to compare the postoperative course after conventional internal limiting membrane peeling (c-ILM) and inverted flap ILM peeling (i-ILM). Patients with i­ILM peeling had preoperatively a significantly larger macular hole MATERIAL AND METHODS: In this study 45 consecutive patients with a full thickness macular hole (FTMH) were divided into two groups (c-ILM vs. i ILM) and evaluated with respect to the postoperative best corrected visual acuity (BCVA) and retinal morphology. Using spectral domain optical coherence tomography (SD-OCT) the integrity of the outer retinal layers, external limiting membrane (ELM), ellipsoid zone (EZ) and outer photoreceptor outer segments (OS) were analyzed postoperatively for at least 6 months. RESULTS: The preoperative aperture in the i­ILM group was significantly larger (i-ILM = 408.4 µm, SD = 157.5 µm; c­ILM = 287.4 µm, SD = 104.9 µm; p = 0.01). The preoperative BCVA and postoperative BCVA after 1 month were significantly better in the group with c­ILM peeling (p = 0.03 and p = 0.001). The postoperative BCVA after at least 6 months showed no significant difference between the two groups (p = 0.24). The ELM was the first of the outer retinal layers to show postoperative recovery in both groups. CONCLUSION: Using the i­ILM peeling technique in this consecutive series it seemed to be possible to achieve a similar postoperative visual outcome in patients with a large FTMH as for patients with a smaller FTMH operated on with the c­ILM peeling technique.

[MEK inhibitor-associated retinopathy under binimetinib treatment for cutaneous malignant melanoma]. / MEK-Inhibitor-assoziierte Retinopathie unter Binimetinib-Therapie bei kutanem malignem Melanom.

The treatment options for patients with metastatic melanoma (MM) have been dramatically expanded in recent years with the approval of new drugs. The MEK (mitogen-acitvated protein kinase kinase) and BRAF (serine/threonine-protein kinase B-Raf coding gene) inhibitor combination therapy is currently part of the standard of care for stage IIIC/IV of BRAF mutant melanoma. The MEK inhibitor-associated retinopathy (MEKAR) is observed in patients with MM who are treated (or have been treated) with such a combination therapy. This article reports the case of a 72-year-old male patient, who suffered from such a pathological condition under treatment with binimetinib in combination with nivolumab. This case study illustrates the importance of interdisciplinary collaboration in the treatment of MM patients.

MMP-9 mediated Syndecan-4 shedding correlates with osteoarthritis severity.

OBJECTIVE: Osteoarthritis (OA) is a degenerative joint disease inducing the degradation of the articular cartilage. Syndecan-4 (Sdc4) is a heparan sulfate proteoglycan, expressed under inflammatory conditions and by chondrocytes during OA. Little is known about Sdc4 shedding and its regulation in OA. Therefore, we investigated the regulation of Sdc4 shedding and underlying shedding mechanisms under OA conditions. DESIGN: Articular cartilage, serum, synovial fluid and synovial membrane from OA patients with different radiological severity were analyzed. ELISA, RT-qPCR and IHC for Sdc4, MMP-2 and -9 were performed. MMP inhibitors and siRNA were evaluated for their effect on Sdc4 shedding by ELISA and on IL-1 signaling by western blot (pERK/ERK). RESULTS: Shed Sdc4 was increased in synovial fluid of OA patients, but not in the serum and is a good predictor (AUC = 0.72) for OA severity with a sensitivity of 67.5% and specificity 65.2%. MMP-9, but not MMP-2, was increased in cartilage and synovial membrane at mRNA levels and in the synovial fluid at protein levels. Shed Sdc4 correlated with the amount of MMP-9 in synovial fluid. Further, the inhibition and knock-down of MMP-9 decreased the amount of shed Sdc4 in vitro. Increased Sdc4 shedding resulted in less phosphorylation of ERK upon IL-1ß stimulation. CONCLUSION: Shed Sdc4 might be a good prognostic biomarker for OA mediated cartilage degradation. MMP-9 seems to be the relevant sheddase for Sdc4 under OA conditions, desensitizing chondrocytes towards IL-1 signaling.

[Microstructural retinal changes after pharmacological vitreolysis with ocriplasmin-an SD-OCT supported analysis]. / Mikrostrukturelle retinale Veränderungen nach pharmakologischer Vitreolyse mit Ocriplasmin ­ eine SD-OCT-gestützte Analyse.

PURPOSE: Ocriplasmin (Jetrea®) is a therapeutic option for patients with focal vitreomacular traction (VMT) with or without small full thickness macular holes (FTMH) < 400 µm. Retinal alterations after injection with ocriplasmin have been described. The purpose of this essay was to determine Ocriplasmin-associated side-effects and changes in the retinal microstructure. METHODS: We included 70 patients with ocriplasmin treatment in our study. On all patients SD-OCT (spectral-domain optical coherence tomography) scans were performed prior to injection with Ocriplasmin. If present, adverse events were registered. The OCT scans were then evaluated taking the following into account: macular hole (MH) size, macular edema, subretinal fluid (SRF), changes in the ellipsoid zone (EZ) and the external limiting membrane (ELM). RESULTS: Twenty of the 70 examined patients showed a preoperative FTMH. One week after ocriplasmin IVI (intravitreal injection) 8 of the 20 FTMHs were already closed. Overall 12 patients showed a FTMH closure and 4 patients developed a FTMH after ocriplasmin IVI. Twelve of the 24 MH (macular hole) patients still required an operative closure of the FTMH. We noticed a resolution of the VMT on 51 patients. Three patients developed a retinal detachment. Furthermore, after ocriplasmin IVI we detected changes in the EZ and ELM on 8 patients. CONCLUSIONS: Ocriplasmin is a substantial minimal invasive option in the therapy of VMT with or without small FTMH. Nevertheless, there seem to be some specific ocriplasmin-associated risks, although usually transient. Severe complications like retinal detachment are rare but exist. Therefore, every indication of ocriplasmin should be considered carefully.

[Real-time optical coherence tomography-assisted high-precision vitreoretinal surgery in the clinical routine]. / Echtzeit-optische Kohärenztomographie-assistierte Hochpräzisionsvitreoretinalchirurgie in der klinischen Routine.

The complete integration of spectral domain optical coherence tomography (SD-OCT) into an operating microscope now enables targeted, high-resolution imaging-guided vitreoretinal surgery. This provides real-time visualization of retinal layers, vitreous body and instrument-tissue interactions, which can be used for intraoperative decision making. Compared to conventional surgical microscopes, intraoperative OCT enables a greatly enhanced precision of vitreoretinal surgical maneuvers and is an essential prerequisite for the implementation of real-time guided surgical techniques at the micrometer level.

[Diagnostic criteria: OCT angiography for retinal angiomatous proliferation (RAP lesions, type 3 neovascularization)]. / Diagnostische Kriterien: OCT­Angiographie bei retinalen angiomatösen Proliferationen (RAP­Läsionen, Typ­3-Neovaskularisationen).

BACKGROUND: Multimodal imaging of retinal angiomatous proliferation (RAP) lesions (type 3 neovascularization) and the diagnostic significance of optical coherence tomography angiography (OCT-A). MATERIAL AND METHODS: Confirmation of the diagnosis in six case reports with fundus photography, optical coherence tomography (OCT), fluorescein angiography (FLA), indocyanine green angiography (ICGA) and optical coherence tomography angiography (OCT­A). RESULTS AND CONCLUSION: The use of OCT­A is helpful for the diagnosis and follow-up examinations of RAP lesions (type 3 neovascularization). It enables the detailed visualization of intraretinal and choroidal microcirculation. Furthermore, it is possible to evaluate the progression, classify the stages and comprehend the treatment strategy.

[Bartonella neuroretinitis : An atypical manifestation of cat scratch disease]. / Bartonellenneuroretinitis : Eine atypische Manifestation der Katzenkratzkrankheit.

Cat scratch disease (CSD) typically manifests as a febrile lymphadenopathy and is caused by a Bartonella henselae infection after contact with cats. This article describes the case of an atypical presentation of CSD in a 52-year-old patient with acute unilateral loss of vision and headache without fever or lymphadenopathy. Funduscopic examination showed an optic disc swelling and macular star exsudates, pathognomonic for infectious neuroretinitis. A Bartonella henselae infection was confirmed serologically. Systemic antibiotic combination therapy was initiated with doxycycline and rifampicin for 6 weeks resulting in good morphological and functional results. A Bartonella neuroretinitis should be considered in the differential diagnosis of patients with loss of vision and papilledema, even in the absence of fever or lymphadenopathy. Immediate serological testing and initiation of antibiotics are important for the outcome.

[Intraoperative optical coherence tomography in explorative vitrectomy in patients with vitreous haemorrhage-a case series]. / Intraoperative optische Kohärenztomographie bei explorativer Vitrektomie an Patienten mit Glaskörperblutung ­ eine Fallserie.

BACKGROUND: High-resolution spectral domain optical coherence tomography (SD-OCT) is a gold standard technique for diagnosis, management and monitoring of patients with vitreoretinal diseases. Preoperative diagnostics for evaluation of intraocular and retinal status in patients with vitreous haemorrhage are limited, thus final therapeutic decisions can only be made during explorative vitrectomy. We evaluated the use of intraoperative SD-OCT (iSD-OCT) as a real-time additional diagnostic tool during explorative vitrectomy in patients with vitreous haemorrhage. METHODS: We report on 9 patients (11 eyes) with vitreous haemorrhage. Preoperative ultrasound was performed to evaluate intraocular status. Subsequently, an explorative 23G pars plana vitrectomy was performed under visualisation with the OPMI Lumera 700 surgical microscope (Carl Zeiss Meditec, Jena, Germany) equipped with a fully integrated iSD-OCT device (Rescan 700, Carl Zeiss Meditec, Jena, Germany) as a real-time diagnostic tool. RESULTS: In all patients, intraoperative iSD-OCT allowed real-time evaluation of the preretinal, intraretinal and subretinal structures in addition to the intraoperative en face image. The further surgical strategy, i. e. necessity for peeling of epiretinal membranes (ERM) or of the inner limiting membrane (ILM), application of intravitreal medication and selection of the appropriate tamponade, was based on and optimised according to the iSD-OCT images. CONCLUSION: Intraoperative iSD-OCT is highly useful as an additional intraoperative diagnostic tool in patients with vitreous haemorrhage. In addition to the en face microscope image, it facilitates intraoperative real-time diagnosis and aids therapeutic decision-making during surgery.

[Vitrectomy and iOCT-assisted inverted ILM flap technique in patients with full thickness macular holes]. / Vitrektomie mit iOCT-assistierter invertierter ILM-Flap-Technik bei großen Makulaforamina.

BACKGROUND: In large full thickness macular holes (FTMH) the closure rate after vitrectomy and conventional internal limiting membrane (ILM) peeling is less than 90%. The aim of this study was to examine the visual acuity and anatomical success rate with high-resolution optical coherence tomography (OCT) after transconjunctival sutureless 23-gauge pars plana vitrectomy as well as intraoperative OCT (iOCT) and Brilliant Peel (BP)-assisted ILM peeling using the inverted ILM flap technique in patients with large FTMHs. METHOD: In this retrospective study 25 eyes of 25 consecutive patients with large FTMH were treated by 23-G vitrectomy with BP and iOCT-assisted ILM peeling using the inverted ILM flap technique followed by gas tamponade. In all patients best corrected visual acuity (BCVA) and the maximum diameter, base and height of the FTMH as well as intraretinal alterations were measured preoperatively using high-resolution spectral domain OCT (SD-OCT, Spectralis, Heidelberg Engineering, Germany). The BCVA was measured after 1, 3, and 6 months. Additionally, the closure rate and the microstructural integrity of the outer retinal layers, e.g. external limiting membrane (ELM), ellipsoid zone und photoreceptor outer segment (OS) were registered in the SD-OCT and correlated with the results of BCVA after macular hole surgery. RESULTS: In all surgical procedures with the inverted ILM flap technique the application of iOCT enabled a good visualization and a controlled positioning of the ILM flaps. At baseline mean BCVA was 0.2 (0.7 logMAR) and improved significantly after 1, 3 und 6 months to 0.4 (0.4 logMAR), 0.5 (0.3 logMAR) and 0.63 (0.2 logMAR), respectively. The closure rate of the FTMHs was 100%. Microstructural integrity of the outer retinal layers was evaluated semiquantitatively and showed good correlation with BCVA. CONCLUSION: Vitrectomy with BP and iOCT-assisted ILM peeling using the inverted ILM flap technique in patients with large FTMH is a very controlled and safe microsurgical strategy and shows good functional and anatomical results. The morphology of the FTMH, the ILM flap and the position of the inverted ILM flap under air was well visualized by IOCT. The microstructural integrity of the outer retinal layers is displayed in detail on SD-OCT and represents an important predictive parameter for BCVA after macular hole surgery.

[A young patient with full visual acuity, small visual field defects, and normal fluorescence angiogram]. / Eine junge Patientin mit vollem Visus, kleinen Gesichtsfelddefekten und normalem Fluoreszenzangiogramm.

A 28-year-old female patient came to our clinic complaining of small central visual field defects in both eyes, without any impairments of visual acuity. She reported recent flu-like symptoms and work-related stress associated with high caffeine intake. Dark reddish cloverleaf-shaped lesions were noted in the macular region with red-free fundoscopy, and alterations of the external retinal layers were observed in spectral domain optical coherence tomography (SD-OCT). The visual field test (Octopus, program 32) revealed small central scotoma on both eyes. The fluorescein angiograms were normal. A suspected diagnosis of acute macular neuroretinopathy (AMNR) was made and the patient was scheduled for follow-up 4 weeks later. The follow-up examination showed persisting central scotoma as well as persistence of the lesions in the external retinal layers in OCT. The best-corrected visual acuity was still 20/20. In OCT angiography (OCT-A), a reduced correlation signal and therefore perfusion was detected in the outer retinal capillary plexus within the area of the fundoscopic macular lesions. Multimodal imaging, including SD-OCT and A­OCT, plays a pivotal role in the diagnosis of acute macular neuroretinopathy. Even though no serious impairments of visual acuity are reported, patients should be informed about the possibility of permanent central scotoma.

Ceramic prosthesis surfaces induce an inflammatory cell response and fibrotic tissue changes.

Aims: Early evidence has emerged suggesting that ceramic-on-ceramic articulations induce a different tissue reaction to ceramic-on-polyethylene and metal-on-metal bearings. Therefore, the aim of this study was to investigate the tissue reaction and cellular response to ceramic total hip arthroplasty (THA) materials in vitro, as well as the tissue reaction in capsular tissue after revision surgery of ceramic-on-ceramic THAs. Patients and Methods: We investigated tissue collected at revision surgery from nine ceramic-on-ceramic articulations. we compared our findings with tissue obtained from five metal-on-metal THA revisions, four ceramic-on-polyethylene THAs, and four primary osteoarthritis synovial membranes. The latter were analyzed to assess the amount of tissue fibrosis that might have been present at the time of implantation to enable evaluation, in relation to implantation time, of any subsequent response in the tissues. Results: There was a significant increase in tissue fibrosis with implantation time for all implant types tested. Interestingly, the tissue fibrosis in ceramic-on-ceramic THAs was significantly increased compared with metal-on-metal and ceramic-on-polyethylene. Additionally, we found ceramic wear particles in the periprosthetic tissue of ceramic implants. Fibroblasts responded with expression of cytokines when cultured on alumina-toughened zirconia (ATZ) and zirconia-toughened alumina (ZTA) ceramic surfaces. This response was more pronounced on ATZ ceramics compared with ZTA ceramics. The same inflammatory response was observed with peripheral blood mononuclear cells (PBMCs) cultured on ZTA and ATZ. Conclusion: Our findings therefore, corroborate the previous findings that ceramic-on-ceramic periprosthetic revision tissue is fibrous and offer an explanation for this observation. We detected a long-term inflammatory response of PBMCs and an inflammatory response of fibroblasts to ATZ and ZTA ceramic. These findings partially explain the fibrotic tissue change in periprosthetic tissue of ceramic-on-ceramic bearings. Cite this article: Bone Joint J 2018;100-B:882-90.

Targeting ß-catenin dependent Wnt signaling via peptidomimetic inhibitors in murine chondrocytes and OA cartilage.

OBJECTIVE: The canonical Wnt signaling pathway has been shown to be involved in regulating chondrocyte hypertrophic differentiation during Osteoarthritis (OA). The aim of this study was to test the therapeutic potential of two stapled peptide canonical Wnt inhibitors - SAH-Bcl9 and StAx-35R - in preventing Wnt induced cartilage changes in OA. METHODS: Primary neonatal murine chondrocytes and cartilage explants from OA patients undergoing total joint replacement for knee OA, were used for microscopy to determine matrix and cell penetrating capacity of fluorescein isothiocyanate FITC-tagged SAH-Bcl9 and StAx-35R peptides. T cell factor/lymphoid enhancer-binding factor (TCF/LEF) reporter assays were used to monitor the inhibition of Wnt3a induced ß-catenin signaling by each peptide. Changes in chondrocyte phenotypic marker gene expression were analyzed by qRT PCR. RESULTS: Both peptides localized intercellular in primary murine chondrocytes and cartilage explants. They inhibited Wnt3a induced TCF/LEF promoter activity in primary murine chondrocytes. Both inhibitors did not rescue Wnt3a altered expression of chondrocyte phenotypic genes (Sox9, Col2a1, Acan) and hypertrophy marker gene (Col10a1) at high doses (100 ng/ml). Upon application of 10 ng/ml Wnt3a, StAx-35R partially reversed the Wnt effect on Sox9 and Col2a1 gene expression. Both peptides, however, reversed the downregulation of SOX9 and aggrecan (ACAN), and decrease of COL10A1 gene expression in preserved human OA cartilage explants. CONCLUSION: These data indicate that blockade of canonical Wnt signaling might be a therapeutic strategy to treat early OA cases and protect further cartilage degradation by preventing chondrocyte hypertrophic differentiation.

The effect of irrigation time and type of irrigation fluid on cartilage surface friction.

It is known that fluid irrigation used during arthroscopic procedures causes a wash-out of lubricating substances from the articular cartilage surface and leads to increased friction. It was the goal of this study to investigate whether this effect depends on the time of irrigation and type of fluid used. Rabbit hind legs were used for the tests. The knees were dissected and the friction coefficient of the femoral cartilage measured against glass in a boundary lubrication state. To determine the influence of irrigation time and fluid, groups of 12 knees received either no irrigation (control), 15, 60 or 120min of irrigation with lactated Ringer's solution or 60min of irrigation with normal saline or a sorbitol/mannitol solution. The time of irrigation had a significant effect on the static and kinetic coefficient of friction (CoF), as had the type of fluid. Longer irrigation time with Ringer's solution was associated with increased friction coefficients (relative increase of the kinetic CoF compared to the control after 15, 60 and 120min: 16%, 76% and 88% respectively). The sorbitol/mannitol solution affected the static and kinetic CoF significantly less than either Ringer's or normal saline. The washout of lubricating glycoproteins from the cartilage surface and the associated increase of friction can be effectively influenced by controlling the time of irrigation and type of fluid used. The time of exposure to the irrigation fluid should be as short as possible and monosaccharide solutions might offer a benefit compared to salt solutions in terms of the resultant friction.

[Maculopathy with optic nerve pits : Morphological criteria in SD-OCT]. / Makulopathie bei Grubenpapille : Morphologische Kriterien im SD-OCT.

PURPOSE: Optic pit is a congenital anomaly with malformation similar to coloboma of the optic disc. The cause of optic pit maculopathy is controversial. We used high resolution OCT to investigate changes in the vitreoretinal and vitreopapillary transition within optic pit eyes. METHODS: The vitreoretinal and vitreo-papillary transition of 12 eyes was accurately analyzed using SD-OCT. We registered the following criteria: liquefaction of prepapillary vitreous, papillary vitreous traction, discontinuity within the hyaloid cortex and communication spaces between pit and retinal edema. RESULTS: Communication gaps between pit and retinal edema were identified in 8 eyes. 4 eyes had a papillary vitreous traction. 4 showed a discontinuity in the hyaloid cortex. 2 of the 12 patients showed no maculopathy in SD-OCT. Those patients had an adjacent papillary vitreous without prepapillary liquefaction. However all eyes showed vitreous liquefaction at some stage premacullary or prepapillary. CONCLUSION: Yet the cause of optic pit maculopathy is not clearly understood. High resolution OCT imaging provides a very detailed assessment of the vitreoretinal transition prepapillary and premacullary, however with limited penetration depth and analyzation of deeper lying structures. Our observations suggest that prepapillary liquefaction and pressure gradients within cerebrospinal and intraokular pressure could be key factors.

[Fluorescein, indocyanine green and optical coherence tomography angiography in patients with native exudative age-related macular degeneration]. / Fluoreszein­, Indocyaningrün- und optische Kohärenztomographie-Angiographie bei Patienten mit nativer exsudativer altersabhängiger Makuladegeneration.

INTRODUCTION: The newly developed optical coherence tomography angiography (OCT-A) has provided new means to depict the vascular plexus in neovascular age-related macular degeneration (nAMD). If these images are to be used as a basis for therapeutic decisions, it is of vital importance to classify choroidal neovascularization (CNV) as either classical or occult. This study aimed at comparing the findings in OCT-A imaging of CNV with the traditional multimodal imaging through fluorescein angiography (FLA) and indocyanine green angiography (ICGA). METHODS: For this investigation 13 eyes from 13 patients with CNV on the basis of untreated nAMD were studied using FLA, ICGA, spectral domain OCT and OCT-A. All CNV were classified on the basis of SD-OCT and OCT-A images by two independent raters. Thereafter FLA and ICGA images were analyzed to set the gold standard for the classification and the ratings were compared to the previous SD-OCT and OCT-A results. RESULTS: 88% of eyes were correctly classified as either classical or occult CNV on the basis of SD-OCT and OCT-A images. Based on the CNV subgroups, 93% of classical CNV were identified using OCT-A images. In contrast occult CNV was correctly classified in 83% of patients. The interrater agreement was 77%. In general it was noted that the more the retina was pathologically altered, e. g. by edema or vascular pigment epithelium detachment, the harder it became to correctly classify the CNV. DISCUSSION: These results show that OCT-A can be used as an interesting addition in the diagnosis of CNV in nAMD. All CNV could be visualized using OCT-A and especially classical CNV could be clearly recognized in most cases. In contrast occult CNV could be identified in slightly fewer cases.

[Multimodal imaging in Goldmann-Favre syndrome]. / Multimodale Bildgebung beim Goldmann-Favre-Syndrom.

Case report of a 23-year-old male patient suffering from Goldmann-Favre syndrome. The patient reported bilateral visual loss since 10 years of age and difficulties with dark adaptation for 2 years. Until recently a final diagnosis was not found. Multimodal imaging using multicolor fundus imaging (MCFI), optical coherence tomography (OCT), fundus autofluorescence (FAF), fluorescein angiography (FLA), electroretinography (ERG) and visual evoked potential (VEP) confirmed the diagnosis. We describe multimodal imaging of this rare hereditary retinal dystrophy. For diagnosis of Goldmann-Favre syndrome a multimodal examination is helpful. To confirm the diagnosis a genetic analysis is necessary.
