PURPOSE There is evidence that altered optic nerve head (ONH) blood flow may play a role in the development and progression of glaucoma. In the present study, the baseline characteristics were examined in a study population participating in a clinical trial in which the ocular hemodynamic effects of timolol and dorzolamide were compared. METHODS One(More)
AIM Conventional time-domain OCT technology for detection of retinal nerve fibre layer (RNFL) neurodegeneration suffers from technical inaccuracy owing to a lack of exact scan centring around the optic disc as well as a true follow-up possibility. In this study, the authors evaluated a novel high-resolution spectral-domain OCT device (SD-OCT) with an(More)
PURPOSE To evaluate long-term local tumor control, visual acuity, and survival after hypofractionated linear accelerator-based stereotactic photon radiotherapy in patients with choroidal melanoma. METHODS AND MATERIALS Between 1997 and 2007, 212 patients with choroidal melanoma unsuitable for ruthenium-106 brachytherapy or local resection were treated(More)
BACKGROUND Recently the reduction of the retinal nerve fibre layer (RNFL) was suggested to be associated with diffuse axonal damage in the whole CNS of multiple sclerosis (MS) patients. However, several points are still under discussion. (1) Is high resolution optical coherence tomography (OCT) required to detect the partly very subtle RNFL changes seen in(More)
The aim of the present study was to investigate the association between ultrasound Doppler measurements of resistive index (RI) in the central retinal artery and retinal vascular resistance (R) assessed with laser Doppler velocimetry, vessel size measurement, and calculation of ocular perfusion pressure (PP) in healthy subjects. An increase in vascular(More)
We report an 8-year-old Caucasian boy who presented with steroid-resistant nephrotic syndrome. Renal biopsy showed the cellular variant of focal segmental glomerulosclerosis (FSGS). Within 1 year he received a series of therapies that have induced remission in other patients with this disease, all to no avail (conventional-dose cyclosporin A,(More)
Between January 1996 and September 1999, 13,650 serum samples from 12,337 patients were examined for antibodies to Mycoplasma pneumoniae at the Institute of Hygiene, University Hospital Vienna in the course of routine diagnosis. Antibody determination was performed by means of the microparticle agglutination assay Serodia Myco II. Overall, positive results(More)
OBJECTIVE To monitor the venous volumes in plaques of patients with multiple sclerosis (MS) compared to an age-matched control group over a period of 3.5 years. METHODS Ten MS patients underwent an annual neurological examination and MRI. Susceptibility-weighted imaging (SWI) combined with fluid-attenuated inversion recovery (FLAIR) or FLAIR-like contrast(More)
PURPOSE To evaluate long-term safety and efficacy of hypofractionated stereotactic photon radiotherapy with 5 five fractions at 10 Gy each in patients with centrally located choroidal melanoma. MATERIALS AND METHODS Ninety-one patients with centrally located choroidal melanoma were treated stereotactically at a linear accelerator with 6 MV photon beams(More)
PURPOSE To evaluate side effects of hypofractionated stereotactic photon radiotherapy for patients with choroidal melanoma. PATIENTS AND METHODS Two hundred and twelve patients with choroidal melanoma unsuitable for ruthenium-106 brachytherapy or local resection were treated stereotactically at the Medical University of Vienna between 1997 and 2007 with a(More)
