Robust detection of microaneurysms for sight threatening retinopathy screening [PDF]

, 2008
Diabetic retinopathy is one of the major causes of blindness. However diabetic retinopathy does not usually cause a loss of sight until it has reached an advanced stage.

Dissecting the angiogenic mechanism of pachychoroid polypoidal choroidal vasculopathy

iMeta, EarlyView.
A prognosis‐oriented classification system was established to distinguish Pachy PCV from Non‐pachy PCV using a large multicenter dataset. Comparative plasma multi‐omics profiling of Pachy PCV, Non‐pachy PCV, and normal controls revealed unique upregulation of the fluid shear stress and atherosclerosis (FSS‐AS) and HIF‐1 signaling pathways in Pachy PCV.

Mean curvature and texture constrained composite weighted random walk algorithm for optic disc segmentation towards glaucoma screening

Healthcare Technology Letters, 2018
Accurate optic disc (OD) segmentation is an important step in obtaining cup-to-disc ratio-based glaucoma screening using fundus imaging. It is a challenging task because of the subtle OD boundary, blood vessel occlusion and intensity inhomogeneity.

Analysis of High‐Risk Factors for Failure of Bleeding Control in Enhanced Myometrial Vascularity Treated With Uterine Artery Embolization

Journal of Clinical Ultrasound, EarlyView.
Enhanced Myometrial Vascularity (EMV) is a serious gynecological condition that often leads to abnormal uterine bleeding. Malformation size and involvement of the uterine fundus are significant risk factors. If EMV diameter > 3.85 cm, the bleeding of the patient is more likely to result in failure in UAE treatment.

Visualization of the Persistent Avascular Retina with Ultra-Widefield Green Reflectance Imaging

Diagnostics
Objectives: The aim of this study was to determine which color imaging facilitated easier detection of the persistent avascular retina (PAR) in ultra-widefield (UWF) fundus imaging in children undergoing retinopathy of prematurity (ROP). Methods: A total

Case report of a gastric bezoar causing anterograde gastroduodenal intussusception requiring surgical intervention in a 15‐year‐old female

JPGN Reports, EarlyView.
Abstract Gastroduodenal bezoars are masses of indigestible material that accumulate within the stomach and may lead to obstruction. We present a young female who presented with abdominal pain, nausea, and vomiting, and was found to have a large gastric bezoar extending into the duodenum, resulting in gastroduodenal intussusception.

Group ingestion of high‐powered magnets in children—A clinical and public health challenge

JPGN Reports, EarlyView.
Abstract High‐powered magnets are a preventable cause of serious gastrointestinal injury in children, with ingestion often resulting in hospitalization and occasionally surgery. We report six classmates, aged 5–6 years, who ingested high‐powered magnets during a single school day after mistaking them for candy. All presented to our emergency department

Beyond Skin and Eyes: The Medical and Social Burden of Oculocutaneous Albinism in Africa: A Narrative Review

JEADV Clinical Practice, EarlyView.
ABSTRACT Oculocutaneous albinism (OCA) is a genetic disorder found worldwide, but its impact is particularly pronounced in the African continent. This results from both a higher prevalence and the persistent myths and superstitions surrounding the condition in many African communities.

Automated Tessellated Fundus Detection in Color Fundus Images

Proceedings of the Ophthalmic Medical Image Analysis Third International Workshop, 2016
In this work, we propose an automated tessellated fundus detection method by utilizing texture features and color features. Color moments, Local Binary Patterns (LBP), and Histograms of Oriented Gradients (HOG) are extracted to represent the color fundus image. After feature extraction, a SVM classifier is trained to detect the tessellated fundus. Both
