Retina Summit Karlsruhe 2009

2009

During the this year´s Retina Summit Karlsruhe, an international expert faculty of 20 highly renowned retina specialists and more than 300 participants found their way to Karlsruhe to share their knowledge of the latest trends in surgical technology and pharmacology. After an angiography course on Friday, the 1-day symposium of almost 40 short lectures covered recent developments in age-related macular degeneration and diabetic macular edema, and the implications and challenges associated with microincision vitrectomy surgery, new devices and advances in imaging technologies.

Analysis of the Peripapillary and Macular Regions Using OCT Angiography in Patients with Schizophrenia and Bipolar Disorder

2021

Purpose: To measure RNFL and vasculature around the optic disc and in the macula in patients with schizophrenia (SZ) and bipolar disorder (BD) using optical coherence tomography angiography (OCTA). Methods: 24 eyes of patients with SZ and 16 eyes of patients with BD as well as 30 eyes of healthy subjects were examined with OCTA. The radiant peripapillary capillary (RPC) density and RNFL thickness were measured in the peripapillary area. Moreover, macular thickness and vessel density were measured in both superficial and deep layers. Results: Significantly decreased values of vessel density in the macular deep vascular complex were found in the eyes of patients with SZ, compared to BD and th…

Relevance of lactate level detection in migrane and fibromyalgia

2019

The aim of this study was to determine the blood lactate levels in healthy and pathological subjects, particularly with migraine and fibromyalgia. Moreover we investigated the possible correlation between lactate concentration, postural stability and balance disorders; the composition of the groups were: migraine (n = 25; age 49.7 +/- 12.5), fibromyalgia (n = 10; age 43.7 +/- 21.2), control group (n = 16 age 28.52 +/- 2.4). The results showed that patients with fibromyalgia (FG) had higher lactate levels compared to migraine (MG) and control group (CG) (mean +/- sd: FG = 1.78 +/- 0.9 mmol/L; MG = 1.45 +/- 1 mmol/L; CG = 0,85 +/- 0,07 mmol/L). The same situation was highlighted about the swa…

Recognition of rapid-eye-movement sleep from single-channel EEG data by artificial neural networks: a study in depressive patients with and without a…

1996

An automatic procedure for the online recognition of REM sleep appears to be a necessary tool for selective REM sleep deprivation in depressive patients. To develop such a procedure we applied an artificial neural network to preprocessed single-channel EEG activity. EOG and EMG information was purposely not provided as input to the network. A generalized back-propagation algorithm was used for computer simulation. The sleep profile scored manually according to Rechtschaffen and Kales served as the desired output during the training period and as standard for the judgement of the network output during working mode. Polysomnographic recordings from 5 healthy subjects were pooled to train the …

Langzeitverlauf und angiographische Befunde bei serpiginöser Choroiditis

2006

Background: Long-term follow-up and angiographic findings of serpiginous choroiditis, a chronic disease with recurrences of unknown origin, are reported. Patients and Methods: A retrospective analysis of the data of 4 patients with serpiginous choroidopathy, who were treated in the eye clinic of Mainz in the past 10-18 years was made. Progression of disease was documented by photography, as well as fluorescein and indocyanine green angiography. Patients with acute lesions were treated with steroids per os for some weeks. Results: All 8 eyes developed 2 - 7 recurrences with progression of the chorioretinal scars. In cases of macular involvement the functional results were worse. No choroidal…

MindBEAGLE — A new system for the assessment and communication with patients with disorders of consciousness and complete locked-in syndrom

2017

Patients with disorders of consciousness (DOC) cannot reply to questions or clinical assessments using voluntary motor control, and therefore it is very difficult to assess their cognitive capabilities and conscious awareness. Patients who are locked-in (LIS) are instead fully conscious, and they can communicate with their preserved eye movements. However, when the residual oculomotor activity is also lost (e.g., patients with amyotrophic lateral sclerosis disease of very long duration), the locked-in status becomes complete (CLIS). In CLIS patients, detection of conscious awareness may become very challenging, similarly to the subjects with DOC. mindBEAGLE has a physiological testing batte…
