NCT ID: NCT05730218 Completed - Clinical trials for Rhegmatogenous Retinal Detachment - Macula Off

A Phase 2 Study to Assess the Safety and Efficacy of Intravitreal ONL1204 Ophthalmic Solution in Subjects With Mac-off Retinal Detachment

Start date: April 4, 2023
Phase: Phase 2
Study type: Interventional

The goal of this Phase 2 clinical trial is to learn about ONL1204 Ophthalmic Solution in terms of safety and how well the drug works in patients that have a macula-off (central point of vision) rhegmatogenous retinal detachment (RRD). The main questions it aims to answer are: - Does ONL1204 improve vision in macula-off RRD patients when used before retinal detachment repair surgery compared to patients that have surgery alone? - Is ONL1204 safe to use as an add-on drug before retinal repair surgery? Researchers will observe patients that receive two different dosages of ONL1204 Ophthalmic Solution (50 µg or 200 µg) compared to current standard therapy (no treatment) to see if there are differences in vision and safety outcomes.

NCT ID: NCT05531760 Completed - Clinical trials for Pseudophakic Bullous Keratopathy

Predictive Factors of Graft Detachment Following Dmek

PDF DMEKDETACH
Start date: March 1, 2022
Phase:
Study type: Observational

The aim of this study was to identify the predictive factors of graft detachment after Descemet Membrane Endothelial Keratoplasty (DMEK) surgery. This retrospective study was conducted on patients aged 18 years, with Fuchs' dystrophy (FECD) or pseudophakic bullous keratopathy (PBK), who were scheduled for DMEK or triple-DMEK (combined phacoemulsification and DMEK surgery). Patients with a history of surgery other than cataract surgery were excluded. The study was conducted between 2014 and 2022 and follow-up was for 3 months. The characteristics of patients with and without graft detachment following surgery were compared using logistic regression.

NCT ID: NCT05519748 Completed - Dissociation Clinical Trials

Effectiveness of an Online Psychoeducation Program for Improving Coping in People With a High Level of Dissociative Symptoms: A Pilot Randomized Waitlist-controlled Trial

Start date: September 1, 2022
Phase: N/A
Study type: Interventional

Subject Population Our study's target population is people with pathological dissociation in the community. Research Design A pilot randomized waitlist-controlled trial will investigate the effects of an online psychoeducation program on coping, symptom management, and self-efficacy of people with pathological dissociation immediately (posttest-1) and 2-month (posttest-2) post-intervention. Supplementary semi-structured interviews will be conducted for process evaluation. The analysis and reporting of the trial will strictly follow the CONSORT guidelines. Instrument The primary outcome of our study is the coping ability of individuals with pathological dissociation, which will be assessed by the Brief Coping Orientation to Problems Experienced Inventory (Brief-COPE). The secondary outcome measures are dissociative symptoms, emotional regulation, and self-efficacy, which would be assessed by the Dissociative Experiences Scale-Taxon (DES-T), the Emotion Regulation Questionnaire (ERQ), and the General Self-Efficacy Scale (GSES) accordingly. Procedure The online psychoeducation program is developed based on an integrative theoretical framework that integrates the Stress and Coping model, Cognitive-Behavioural Theory, Bandura's self-efficacy theory, and findings of our previous feasibility studies on this psychoeducational program. Participants will be recruited via posting on social media and online forums. A 16-session online psychoeducation program will be delivered to the participants in eight weeks.

NCT ID: NCT05377606 Completed - Clinical trials for Rhegmatogenous Retinal Detachment

Primary Vitrectomy With Silicone Oil or SF6 for Rhegmatogenous Retinal Detachment

Start date: December 23, 2021
Phase: N/A
Study type: Interventional

Rhegmatogenous retinal detachment (RRD) is the separation of the neurosensory retina from the retinal pigment epithelium caused by the presence of a break that leads to the passage of fluid from the vitreous cavity into the potential subretinal space. It is a sight threatening disease, affecting largely people 50 years or older, with an annual incidence varying between 6.3 and 17.9 people per 100,000 population, and is unfortunately increasing. Although other surgical options do exist for the repair of primary RRD, pars plana vitrectomy (PPV) has clear advantages and is certainly effective in the treatment of these patients. Several agents are used for intraocular tamponade following PPV for RRD. These agents are either silicone oil (SO) or gases like air, perfluoropropane (C3F8), sulfur hexafluoride (SF6), or perfluoroethane (C2F6). In addition to the complications uniquely peculiar to using SO, research has found out that a reduction in retinal sensitivity on microperimetry was greater in SO tamponade in comparison with gas, as well as poorer visual outcome, microvasculature damage and affection of retinal layers including ganglion cell complex (GCC) in the SO group. Even though many studies were done to compare between SO and intraocular gas tamponades with respect to many aspects, only one study compared the effects SO had on macular vasculature and anatomy in comparison with air and no study at all to date has compared the SO to SF6 gas in terms of retinal vascular changes, correlating them to thinning of GCC and macular sensitivity, which is precisely the main aim of the current study.

NCT ID: NCT05357131 Completed - Healthy Volunteers Clinical Trials

Neurophysiological Correlates of Dissociation Induced by Virtual Reality Hypnosis.

Start date: June 8, 2022
Phase: N/A
Study type: Interventional

Hypnosis and virtual reality are potential tools in treating acute pain. Nevertheless, the neurophysiological correlates of such tools used together, i.e. 'virtual reality hypnosis' (VRH) (Patterson et al., 2004) remain mostly understudied. This study aims to improve our knowledge and understanding of the dissociation (i.e., a mental separation of components of behaviours that normally would be processed together) occurring during VRH. This is a randomized controlled study that will be conducted on healthy participants. As the final goal is to propose such a tool in the clinical context, a clinical application will also be carried out subsequently. Thus the principal outcome is to study dissociation in the context of VRH from a behavioral and neurophysiological point of view. Secondary objectives aim at identifying factors that influence the dissociative effect seen in VRH, as well as measuring traits of hypnotisability, absorption, immersive abilities, dissociation trait and state, pain, and anxiety levels that might impact the effectiveness of such a tool.

NCT ID: NCT05305014 Completed - Conversion Disorder Clinical Trials

Contribution of Inflammation and Neuronal Integrity Markers in Patients With First-episode Conversive Motor Disorder

HYCOIN
Start date: April 1, 2022
Phase:
Study type: Observational

Conversion disorders, also called "dissociative disorders" (ICD-10), or "functional neurological disorders" (DSM-5), are a common condition, with a prevalence of 1-10% in medical and surgical inpatients (Toone 1990), and 10-30% in neurology patients (Carson et al. 2000). They are characterized by the presence of symptoms or deficits affecting voluntary motor, sensory, or sensory functions suggestive of a neurological or general medical condition in combination with psychological factors. Functional neurological disorder is currently a diagnosis of elimination and its treatment remains uncodified. A better understanding of the pathophysiology of this disorder is needed to improve the diagnostic and therapeutic approach to this condition. Identifying new biological markers associated with motor symptoms occurring during the course of the functional neurological disorder would allow clinicians to acquire new diagnostic methods, to improve therapeutic means and their specificity and to highlight possible predictive factors of the clinical evolution of this pathology. At the same time, the identification of biological markers associated with motor symptoms will allow the patient to better understand and accept the diagnosis, and thus to better adhere to the proposed treatment.

NCT ID: NCT05249413 Completed - Cataract Clinical Trials

Early Vitrectomy for Endophthalmitis After Cataract Surgery

Start date: January 2, 2015
Phase:
Study type: Observational

Post-operative infectious endophthalmitis is devastating condition that causes a diffuse intraocular inflammation and may lead to blindness. Acute post-operative endophthalmitis usually presented within 6 weeks of intraocular procedure and diagnosis is confirmed by clinical examination and by the aid of B-scan ultrasonography.
