Preliminary in vivo positional analysis of a posterior chamber phakic intraocular lens by optical coherence tomography and its correlation with clini…
2012
Purpose: To analyze by spectral-domain optical coherence tomography the anatomical relationship of a specific type of posterior chamber phakic intraocular lens (pIOL) implanted in cases of high to moderate myopia with the adjacent intraocular structures and to correlate it with clinical outcomes. Methods: Prospective observational case series including 18 eyes with high to moderate myopia (spherical equivalent between −5.88 and −15.75 D) of 9 patients (age range, 29–49 years) undergoing bilateral Phakic Refractive Lens (PRL, Zeiss) implantation. Postoperative visual acuity, refraction, contrast sensitivity (CS), and ocular higher order aberrations (HOA) were evaluated. Furthermore, the in v…
The "sandwich technique" for iris-fixated phakic intraocular lens implantation.
2006
ABSTRACT PURPOSE: To describe a new technique of implantation of the Artisan/Verisyse phakic intraocular lens (PIOL). METHODS: After PIOL insertion into the anterior chamber, a bolus of a high viscosity ophthalmic viseosurgical device (OVD) is placed over the optic, separating it widely from the endothelium. RESULTS: The technique decreases the chance of endothelial damage during enclavation. CONCLUSIONS: A bolus of a high viscosity OVD placed on the anterior surface of the Artisan/Verisyse PIOL may make enclavation safer. [J Refract Surg. 2006;22:96-98.]
Pseudomelanome der Aderhaut
2007
BACKGROUND: The aim of this study was to evaluate what are the most frequent ocular diseases that were suspected for choroidal melanoma (”pseudo melanoma”). PATIENTS AND METHODS: The data of all patients who were seen in the University Hospital of Mainz under the suspicion of choroidal melanoma between 1.1.1994 and 1.1.2004 and underwent ultrasound examination, fluorescein angiography or fundus photography, were analysed retrospectively. Among 458 examined eyes a choroidal melanoma was diagnosed in 212 cases. In 246 cases the diagnosis was “pseudomelanoma”. RESULTS: The most frequent ocular diseases suspected for choroidal melanoma were “suspicious nevi” in 31 % of the cases and “disciforme…
Anterior chamber depth measurement in teenagers. Comparison of two techniques
2013
Purpose: The aim of this study is to determine the anterior chamber depth (ACD) in teenagers using two different devices: partial coherence interferometry IOLMaster (Carl Zeiss Meditec) and anterior segment optical coherence tomography (Visante TM OCT, Carl Zeiss Meditec) and to evaluate the degree of agreement between ACD measurements carried out by both instruments. Methods: In this prospective study 68 eyes of 34 emmetropic Caucasic patients (18 girls and 16 boys) were analysed. ACD was measured from the anterior corneal surface to anterior surface of the crystalline lens. For each age the ACD size was calculated and the difference between IOLMaster and Visante-OCT measurements was analy…
Assessment of the Short-Term Effects after High-Inductive Electromagnetic Stimulation of Pelvic Floor Muscles: A Randomized, Sham-Controlled Study
2020
Background: Physiotherapy should be performed by patients with stress or mixed urinary incontinence (SUI and MUI) to increase the strength and endurance of the pelvic floor muscles (PFMs). A method that can positively affect the pelvic floor is stimulation with high-inductive electromagnetic stimulation (HIES). The aim of the study was to evaluate the PFMs after the application of HIES in women with SUI and MUI by using surface electromyography (sEMG). Methods: This was a prospective, randomized, single-blind study with a sham intervention group. The participants were randomly assigned to the HIES group or sham group. The outcomes were features of the bioelectrical PFM activity assessed usi…
Giant right atrial myxoma: A rare cause of cardiovascular collapse
2019
We report the case of a patient with a giant right atrial myxoma that remained clinically silent until it almost completely obliterated the right atrium, prolapsed into the right ventricle and obstructed the tricuspid valve inflow. This case illustrates the importance of rapid surgical intervention in the setting of acute heart failure caused by tumor masses obliterating heart valves or cardiac chambers.
Long-Term Effects of Mind-Body Exercises on the Physical Fitness and Quality of Life of Individuals With Substance Use Disorder—A Randomized Trial
2020
Background: Mind-body exercises (MBE) are sequences of low to medium-intensity activities that benefit healthy performers physically and mentally. In contrast to the unmodified application of traditional tai chi, qi gong, or yoga in the healthy population, MBEs are typically tailored for individuals with substance abuse disorder (SUD). Despite numerous applications in practice, the detailed effects of tailor-made MBEs for SUD are unclear.Objectives: This study aimed to analyze and compare changes in the physical fitness and quality of life of individuals with SUD that underwent conventional or tailor-made MBEs.Methods: A total of 100 subjects obtained from the Shanghai Mandatory Detoxificat…
Cognitive screening tests as experienced by older hospitalised patients: a qualitative study
2011
Older people admitted to geriatric wards in hospitals are often screened for cognitive impairments. The validity and diagnostic concerns of cognitive screening tests have been subjected to comprehensive research. However, the qualitative knowledge available on how older patients themselves experience these screening tests is limited. The aim of this study is to explore the cognitive screening test experience from the older patients' perspective. Drawing on fieldwork, qualitative interviews were performed with 18 older patients who had completed cognitive screening tests while hospitalised. Data from the interviews were analysed according to a phenomenological approach. The results were supp…
P-Wave Indices: Derivation of Reference Values from the Framingham Heart Study
2010
P wave indices constitute an intermediate, phenotype reflecting the impact of ischemic, metabolic and inflammatory insults on atrial electrophysiology and morphology. Measured from the surface electrocardiogram (ECG), they reflect dimensions of atrial depolarization and are modified by conditions that alter atrial conduction, atrial refractoriness, or may result in a proarrhythmic substrate. The P wave indices of duration and dispersion have most commonly been measured. An array of studies have utilized these P wave indices to distinguish subjects with diverse cardiovascular and non-cardiovascular conditions and diseases from healthy reference groups.(1) Computerized software has more recen…
