Abstract Background Widespread use of retinal optical coherence tomography angiography (OCT-A) imaging in population-based studies requires methodological and analytical consensus to ensure reproducible accurate results. Objective Development a framework for assessment OCT-A image quality working with OCT-A-derived variables population studies. Methods Criteria were developed fovea-centered, 3x3-mm images acquired three commercially available devices. Inter- intragrader agreements overall...
We present a compact multi-modal and multi-scale retinal imaging instrument with an angiographic functional extension for clinical use. The system integrates scanning laser ophthalmoscopy (SLO), optical coherence tomography (OCT) OCT angiography (OCTA) modalities provides fields of view. For high resolution, lateral resolution in particular, cellular correction aberrations by adaptive optics (AO) is employed. entire has design the head mounted on motorized translation stages that enable 3D...
Abstract This study tested if a high-resolution, multi-modal, multi-scale retinal imaging instrument can provide novel information about structural abnormalities in vivo. The examined 11 patients with very mild to moderate non-proliferative diabetic retinopathy (NPDR) and 10 healthy subjects using fundus photography, optical coherence tomography (OCT), OCT angiography (OCTA), adaptive optics scanning laser ophthalmoscopy (AO-SLO), OCTA (AO-OCT(A)). Of 21 eyes of patients, had NPDR, 8 2 1 no...
Motion artefacts from involuntary changes in eye fixation remain a major imaging issue optical coherence tomography (OCT). This paper reviews the state-of-the-art of retrospective procedures to correct retinal motion and axial OCT imaging. Following an overview induced correction strategies, chronological survey approaches since introduction until current days is presented. Pre-processing, registration, validation techniques are described. The review finishes by discussing limitations...
To develop and assess an automatic procedure for classifying staging glaucomatous vascular damage based on optical coherence tomography angiography (OCTA) imaging.OCTA scans (Zeiss Cirrus 5000 HD-OCT) from a random eye of 39 healthy subjects 82 glaucoma patients were used to new classification algorithm multilayer multisector information. The averaged circumpapillary retinal nerve fiber layer (RNFL) thickness was also collected. Three models, support vector machine (SVM), forest (RF),...
The Continuous bright light conditions to which premature infants are subjected while hospitalized in Neonatal Intensive Care Units (NICU) can have deleterious effects terms of growth and development. This study evaluates the benefits a light/darkness cycle (LDC) weight early hospital discharge from NICU. Subjects were recruited three participating institutions Mexico. Eligible patients (n = 294) who low-risk high-risk neonatal units classified as stable. subjects randomized experimental...
Conjunctival hyperemia or conjunctival redness is a symptom that can be associated with broad group of ocular diseases. Its levels severity are represented by standard photographic charts visually compared the patient’s eye. This way, diagnosis becomes nonrepeatable task depends on experience grader. To solve this problem, we have proposed computer-aided methodology comprises three main stages: segmentation conjunctiva, extraction features in region based colour and presence blood vessels,...
Abstract Background: Rucaparib is a poly(ADP-ribose) polymerase inhibitor approved in Europe as maintenance therapy for recurrent platinum-sensitive (Pt-S) ovarian cancer (OC). The Access Programme (RAP) was designed to provide early access rucaparib the above-mentioned indication, well patients with BRCA -mutated Pt-S or platinum-resistant (Pt-R) OC and no therapeutic alternatives. Methods: In this observational, retrospective study we analysed efficacy safety of within RAP Spain. Hospitals...
This paper presents a novel image analysis strategy that increases the potential of macular Optical Coherence Tomography (OCT) by using speckle features as biomarkers in different stages glaucoma. A large pool (480) were computed for subset OCT volumes Leuven eye study cohort. The dataset contained 258 subjects divided into four groups based on their glaucoma severity: Healthy (56), Mild (94), Moderate (48), and Severe (60). categorized statistical properties, distributions, contrast,...
Abstract Background Acute Retinal Pigment Epitheliitis (ARPE, Krill’s disease) is a rare inflammatory retinal disorder commonly affecting young adults. It often presents unilaterally with central vision disruption, and typically resolves restoration within 6 to 12 weeks. The pathogenesis of ARPE remains subject ongoing debate. Adaptive Optics Flood Illumination Ophthalmoscopy (AO-FIO) imaging has emerged as valuable tool capable detecting early cone photoreceptor changes recovery. This case...
Hyperemia is the occurrence of redness in a certain tissue. When it takes place on bulbar conjunctiva, can be an early symptom different pathologies, hence, importance its quick evaluation. Experts grade hyperemia as value continuous scale, according to severity level. As subjective and time consuming task, automatisation priority for optometrists. To this end, several image features are computed from video frame that shows patientâs eye. Then, these transformed grading scale by means...
