Patients with multiple sclerosis (MS) and clinically isolated syndrome (CIS) may show alterations of retinal layer architecture as measured by optical coherence tomography. Little is known about changes in the vascular network during MS.To characterize vessel structures patients MS CIS to test for associations disease activity.In all, 42 or 50 healthy controls underwent tomography angiography (OCT-A) analysis superficial deep plexuses choriocapillaries. We tested OCT-A parameters volumes,...
Subretinal injection is a delicate and complex microsurgery. The main surgical difficulties come from the surgeon's hand tremor, dexterous motion, insufficient visual feedback. In order to begin addressing these challenges, this article presents robot system for subretinal insertion integrated with intraoperative optical coherence tomography (OCT). workflow using consists of two parts. first part manual control, which aims target before approaching retinal surface, while considering remote...
Intravitreal injections are used extensively to treat retinal diseases. Performing an intravitreal injection increases intraocular volume by the amount of fluid brought into eye. Whether this influences pressure (IOP) was investigated here.A biomechanical model relying on 3-dimensional elasticity theory developed determine short-term effect changes IOP. We calculated for 0.1 ml in myopic, emmetropic and hyperopic eyes. Our calculations were compared with IOP measurements obtained immediately...
This paper introduces the design and development of a new robotic system to assist surgeons performing ophthalmic surgeries. The robot itself is very compact similar an average human hand in size. Its primary application intraocular micromanipulation order overcome existing challenges treatment diseases like Retinal Vein Occlusion (RVO). novel hybrid mechanism designed for this allows microscale motions stable presence vibrations common operation room (OR). can be easily integrated into...
Abstract. Purpose: To evaluate the efficacy of intravitreal dexamethasone implants in eyes with cystoid macular oedema (CME) secondary to branch retinal vein occlusion (BRVO) or central (CRVO) clinical everyday practice, examine effects early retreatment and compare results GENEVA study. Methods: The charts 102 patients (102 eyes) CME BRVO ( n = 54) CRVO 48) treated Ozurdex at 8 centres were retrospectively reviewed. examined monthly over a 24‐week period. Slit‐lamp biomicroscopy,...
Neuromyelitis optica spectrum disorders (NMOSD) are neuroinflammatory diseases of the central nervous system. Patients suffer from recurring relapses and it is unclear whether relapse-independent disease activity occurs this clinical relevance.To detect disease-specific alterations retinal vasculature that reflect during NMOSD.Cross-sectional analysis 16 patients with NMOSD, 21 relapsing-remitting multiple sclerosis, healthy controls using optical coherence tomography (OCT), angiography...
This paper presents the kinematic and dynamic analysis of a robot for 6 Degrees Of Freedom (DOF) micromanipulation. is designed performing intraocular manipulation but its application not limited to ophthalmic surgery. The novel hybrid parallel-serial mechanism this enables microscale motions with high stiffness sufficient output forces. portable can be easily integrated into standard biomedical environments does require any modification conventional surgical tools. contribution work design...
Ophthalmic microsurgery is known to be a challenging operation, which requires very precise and dexterous manipulation. Image guided robot-assisted surgery promising solution that brings significant improvements in outcomes reduces the physical limitations of human surgeons. However, this technology must further developed before it can routinely used clinics. One problems lack proper calibration between robotic manipulator appropriate imaging device. In letter, we flexible framework for...
Escherichia coli is a common inhabitant of the gastrointestinal tract most animals. Like pathogenic E. coli, avian isolates cannot be distinguished biochemically from normal commensals inhabiting birds. Using molecular approach, we were able to identify genetic differences among by restriction fragment length polymorphism (RFLP) and random amplification polymorphic DNA (RAPD) polymerase chain reaction (PCR). Several different RFLPs observed using probes for 16S ribosomal RNA genes (rrn)...
Abstract Purpose To investigate morphological and functional outcomes of the inverted internal limiting membrane (I-ILM) flap technique in large (≥ 400 μm) idiopathic full-thickness macular holes (FTMH) over a follow-up period 12 months. Methods In this retrospective study, 55 eyes 54 consecutive patients were enrolled. Best-corrected visual acuity (BCVA) spectral-domain optical coherence tomography (SD-OCT, Heidelberg, Spectralis) performed preoperatively as well 1, 3, 6, 9, months...
To investigate whether vaccination against SARS-CoV-2 is associated with the onset of retinal vascular occlusive disease (RVOD).In this multicentre study, data from patients central and branch vein occlusion (CRVO BRVO), artery (CRAO BRAO), anterior ischaemic optic neuropathy (AION) were retrospectively collected during a 2-month index period (1 June-31 July 2021) according to defined protocol. The relation any previous was documented for consecutive case series. Numbers RVOD COVID-19...
O Art. 26 do Código Penal dispõe sobre circunstâncias que tratam da exclusão de culpabilidade em determinadas situações associadas às condições mentais e psicológicas indivíduo no momento prática ato criminoso, como insanidade mental e/ou transtornos mentais, logo o presente trabalho tem objetivo principal realizar uma análise crítica artigo citado aplicado a casos associados à psicológicas. Levando consideração necessidade se avaliar capacidade agente ação, buscamos descrever analisar...
To assess whether there were any differences in patient presentation, morphological and functional features as well surgical treatment for full-thickness macular holes (FTMH) during the lockdown periods amidst COVID-19 pandemic compared to previous year. A retrospective analysis was conducted on all patients with FTMH who received at a large tertiary center from March 16 June 16, 2020, December 9, 6, 2021 (35 eyes, mean age 66 years). Corresponding year chosen control group (41 71 The...
Aflibercept, 8 mg, is an anti-vascular endothelial growth factor (VEGF) formulation for neovascular age-related macular degeneration (nAMD) and diabetic edema (DME). While clinical trials report a comparable safety profile as aflibercept, 2 practice setting (so-called real-world) data on the incidence of intraocular inflammation (IOI) should be value. To determine IOI after intravitreal injection nAMD DME. This retrospective case series involved review medical records at single tertiary care...
This report concerns a patient with cardiac manifestation of Whipple's disease. For the first time, gene that encodes 16s rRNA Tropheryma whippelii was identified in native aortic valve by means polymerase chain reaction technique. DNA amplification gives evidence as causative organism infective endocarditis.
This paper presents the virtual fixture control methods for a hybrid parallel-serial micromanipulator, which is designed assisting ophthalmic surgeons. Virtual fixtures are features of surgical robotic setups to improve quality surgery and reduces operation risk. In domain lack in manual operations has limited, sometimes even blocked, treatment options. The contribution this concept analysis implementation flexible novel mechanism experimentally evaluation concept. using enables user adjust...
