Secondary objectives: To evaluate the level of agreement between the NOTAL-OCT V2.5 and a commercial OCT in the presence of fluid as identified in the OCT images, in the central 10 degrees of the macula in DME (Diabetic Macular Edema) patients. To evaluate patient experience when self-operating the Notal-OCT V2.5.

The visual prognosis of optic neuritis not related to multiple sclerosis is unknown, both in terms of functional recovery and evolution. This prospective cohort study aim to assess the ophthalmological evolution of patients presenting an episode of optic neuritis (NO) not related to a multiple sclerosis or to a clinically isolated syndrome.

The main hypothesis is that exposure to repeated shocks is associated with a greater decrease in the thickness of optical nerve fibres. In order to show a association between the occurrence of concussions (in number and severity) and the variation in the thickness of the retinal nerve fibre layer, all participating rugby players will have an ophthalmologic examination (OCT and (retinophotography) at the beginning and end of the Rugby season.

Chronic kidney disease (CKD) affects 8-16% of the world's population, and is independently associated with cardiovascular disease (CVD). As renal function declines, rates of major adverse cardiovascular events, cardiovascular and all-cause mortality increase. In addition to hypertension, increased arterial stiffness is characteristic of CKD, a marker of CVD risk, and an independent predictor of mortality in CKD patients. The endothelium is an important regulator of arterial stiffness, and endothelial dysfunction is a feature of CKD and a predictor of CVD. Current treatment of CKD is limited and aims to reduce blood pressure and proteinuria through the use of angiotensin ...

NSTE-ACS patients are more likely to exhibit high-risk plaque characteristics in non-culprit lesions. Both IVUS and OCT imaging techniques interact in a complementary manner to provide morphological characterization of the atherosclerotic coronary plaques and help identification of high-risk vulnerable plaques. Using morphological parameters obtained from OCT and IVUS, a new plaque vulnerability score will be established for more precise definition of the most vulnerable plaques that carry the greatest risk of rupture and subsequent detrimental clinical outcomes in the future. Such score might help in targeting these plaques with certain therapeutic interventions aiming to their stabilization.

Optical Coherence Tomography Angiography (OCT-A) is a noninvasive imaging technique that allows one to see blood vessels in the retina. The investigating team used this approach in patients with acute, recurrent and persistent subtypes of Central Serous Chorioretinopathy (CSC) to check for possible Choriocapillaris hypoperfusion. The presence or absence of these microvascular changes was explored in both eyes of the patients and compared to a control group of healthy volunteers. The possibility of a correlation between Choriocapillaris flow deficits, age and spontaneous resolution of serous retinal detachment was also evaluated. This study was conducted in an effort to improve one ...

This study will compare by swept-source optical coherence tomography (SS-OCT) the retinal morphology after inverted internal limiting membrane (I-ILM) flap vitreoretinal surgery for medium-to-large macular holes using infracyanine green (IFCG) vs brilliant blue G (BBG) dyeing. It is a single-center prospective, randomized study. One group of patients will undergo I-ILM vitrectomy with IFCG staining, the other vitrectomy with BBG staining. Postoperative six-month corrected distance visual acuity, macular hole closure rate, and SS-OCT parameters will be compared and statistically analyzed. The aim of the study is to verify if these parameters can be negatively affected by toxicity related to the use ...

True-false-true occurred during wire penetration in coronary CTO procedure. Subintimal stenting influences vascular response. Intravenous ultrasound confirmed wire position in the procedure. Then stenting procedure was performed. Optical coherence tomography was used for exploring long-term vascular response and healing profile after successful coronary stenting in CTO lesions.

The objective is to find if there is a relationship between the Fractal Dimension, the gap, vascular density (VD), the surface, the span ratio and the status of the choroidal neovessels to adjust the interval between 2 intravitreal injections nor on the qualitative aspect of Optical Coherence Structural Tomography but also on quantified quantitative and objective values.

Surgical outcome of patients with macular drusen and co-existing abnormalities of the vitreoretinal interface, who routinely undergo pars plana vitrectomy with membrane peeling, is evaluated. Best corrected visual acuity as well as optical coherence tomography data are compared at baseline and last follow up. The rate of development of choroidal neovascularization postoperatively is noted.

Diabetic retinopathy (DR) is a leading cause of vision loss in working-age Americans. Capillary damage from hyperglycemia causes vision loss through downstream effects, such as retinal ischemia, edema, and neovascularization (NV). Proper screening and timely treatment with laser photocoagulation and anti-vascular endothelial growth factor (VEGF) injections can minimize morbidity. In the last decade, clinicians have been able to use objective structural data from optical coherence tomography (OCT) to guide the treatment of diabetic macular edema. Other aspects of care, however, still largely depend on subjective interpretation of clinical features and fluorescein angiography (FA) to determine the disease severity and treatment ...

Large vessel vasculitis (LVV) causes blood vessel inflammation leading to pain, fatigue and complications such as aneurysm formation and stroke. Treatments used can have significant side-effects. Doctors find it difficult to determine when to start and stop treatment, often leading to over- or under-treatment. A new test is required to determine disease activity that will guide treatment more accurately. This study will recruit participants with active LVV from throughout Scotland in order to assess the ability of two new types of scan - positron emission tomography with magnetic resonance imaging (PET/MR) and retinal optical coherence tomography (OCT) - to determine disease ...

The purpose of this study is to be able to describe optical coherence angiography (OCTA) patterns of disease activity and quiescence in eyes that have received treatment. Our target population group is patients that have neovascular age-related macular degeneration and have had treatment with aflibercept for this condition. This is a single-site study and does not involve any masking or treatment allocation.

This is a prospective clinical study that will be conducted at one clinical site located in the United States to assess two grids.

The investigator's study includes two groups of patients, each consists of 25 eyes, group 1 (cataract group)includes patients who are planned for cataract extraction without any other preexisting retinal or optic nerve pathology that may affect the RNFL thickness, while group 2 (combined cataract and glaucoma group) includes patients who are diagnosed with POAG controlled on medical treatment with cataract and planned for cataract extraction only. The OCT scans with complete ophthalmological examination are done before surgery and 6 weeks after uneventful cataract extraction (phacoemulsification with intraocular lens implantation

Optical Coherence Tomography (OCT) machines are non-contact instruments that can provide micrometer scale imaging of biological tissue. Applying the image processing allows us to automatically measure the choroidal thickness with good interclass correlation coefficient to the manual measurements.

The objective of this study is to evaluate the imaging capabilities and image analysis performance of the PhotoniCare TOMi Scope in pediatric patients undergoing tympanostomy tube placement for otitis media. In this observational study, results of TOMi Scope imaging will not affect patient standard of care.

Surgical standard for treating traumatic burn injury scarring is to wait one year following the initial assault prior to beginning treatment. This study investigates the use of fractional ablative CO2 laser when begun within 3 months of a traumatic burn injury and it's impact on scar formation compared to the control. We hypothesized that early intervention would substantially mitigate the formation of scar tissue and help restore more normal appearing skin.

The purpose of this study is to collect measurements of anatomical structures of the posterior pole of the eye based on OCT scans in subjects without clinical signs of pathology.

Survival and functional outcome of stroke is strongly depending on the occurence of pneumonia (stroke-associated pneumonia, SAP). Early diagnose and treatment of SAP is paramount in the treatment of stroke patients. While dysphagia strongly contributes to its pathogenesis, recent years have also shown a strong risk-modulation by CNS injury induced immunosuppression, making stroke patients more susceptible to SAP. Additionally, murine models of stroke showed changes in mucociliary clearance as possible contributors to SAP. It remains unclear, whether structural integrity and mucociliary clearance of the respiratory epithel change in stroke patients, and whether these changes might contribute to the occurence of ...

In the realm of cosmetics, skin care accounts for a significant share accounting for 35.3% of the global market, creating a $121 billion industry. While many of the products claim to have unique, natural formulations that boost skin care, many products contain chemicals that are potentially damaging to skin. Such ingredients include preservatives, parabens, fragrances, and formaldehyde, which can cause skin irritation and inflammation. Although these ingredients help to preserve the stability and longevity of products, it is plausible to achieve efficacy and improve skin structure without risking unnecessary damage. The condition and health of the dermis rely largely ...
