Clinician-Driven AI: Code-Free Self-Training on Public Data for Diabetic Retinopathy Referral.

Importance: Democratizing artificial intelligence (AI) enables model development by clinicians with a lack of coding expertise, powerful computing resources, and large, well-labeled data sets.

Objective: To determine whether resource-constrained clinicians can use self-training via automated machine learning (ML) and public data sets to design high-performing diabetic retinopathy classification models.

Design, Setting, And Participants: This diagnostic quality improvement study was conducted from January 1, 2021, to December 31, 2021.

Image quality assessment of retinal fundus photographs for diabetic retinopathy in the machine learning era: a review.

This study aimed to evaluate the image quality assessment (IQA) and quality criteria employed in publicly available datasets for diabetic retinopathy (DR). A literature search strategy was used to identify relevant datasets, and 20 datasets were included in the analysis. Out of these, 12 datasets mentioned performing IQA, but only eight specified the quality criteria used.

Diabetic retinopathy classification for supervised machine learning algorithms.

Background: Artificial intelligence and automated technology were first reported more than 70 years ago and nowadays provide unprecedented diagnostic accuracy, screening capacity, risk stratification, and workflow optimization. Diabetic retinopathy is an important cause of preventable blindness worldwide, and artificial intelligence technology provides precocious diagnosis, monitoring, and guide treatment. High-quality exams are fundamental in supervised artificial intelligence algorithms, but the lack of ground truth standards in retinal exams datasets is a problem.

Clinician-driven artificial intelligence in ophthalmology: resources enabling democratization.

Purpose Of Review: This article aims to discuss the current state of resources enabling the democratization of artificial intelligence (AI) in ophthalmology.

Recent Findings: Open datasets, efficient labeling techniques, code-free automated machine learning (AutoML) and cloud-based platforms for deployment are resources that enable clinicians with scarce resources to drive their own AI projects.

Summary: Clinicians are the use-case experts who are best suited to drive AI projects tackling patient-relevant outcome measures.

Nanostructured faujasite zeolite as metal ion adsorbent: kinetics, equilibrium adsorption and metal recovery studies.

The hydrothermal synthesis of nano-faujasite has been successfully performed and the effects of some crystallization parameters were investigated, along with the use of this material as a heavy-metal ion adsorbent. X-ray diffraction patterns have shown that the structure of the nano-faujasite is strongly dependent on both the crystallization time and the alkalinity of the synthesis medium. According to N physisorption, X-ray fluorescence, SEM/EDS, and solid state Si and Al NMR data, the produced nano-faujasite consists of a solid with low molar Si/Al ratio (1.

VALUE OF CLINICAL, LABORATORY PARAMETERS AND ANALYSIS OF RETINAL VASCULARIZATION IN PEDIATRIC PATIENTS WITH PORTAL HYPERTENSION.

Background: Portal hypertension is one of the complications of cirrhosis and is associated with numerous systemic manifestations, including renal, brain, pulmonary, cardiac and vascular changes. In routine ophthalmological examinations performed at our service, we observed that some children diagnosed with portal hypertension had increased retinal vascular tortuosity.

Objective: 1.

New perspectives on macular hole surgery at three years of follow-up.

Purpose: The aim of this study was to determine the functional and anatomical success rates as well as the safety of sutureless combined surgery involving vitreous base removal and internal limiting membrane peeling after Brilliant Blue G (0.5 mg/mL) staining for the management of idiopathic macular holes after three years.

Methods: Forty-six eyes of 46 patients with an idiopathic macular hole were enrolled in this retrospective study.

INTRAVITREAL DEXAMETHASONE IMPLANT MIGRATION INTO THE ANTERIOR CHAMBER: A Multicenter Study From the Pan-American Collaborative Retina Study Group.

Purpose: To establish the prevalence and risk factors for intravitreal dexamethasone implant migration into the anterior chamber in eyes with macular edema.

Methods: This was a multicenter, retrospective, observational chart review of data that included patients with macular edema who had been treated with at least one intravitreal dexamethasone injection. Patients with incomplete chart information during the follow-up period were excluded.

Analysis of Anthocyanins Extracted from the Acai Fruit (): A Potential Novel Vital Dye for Chromovitrectomy.

Purpose: To classify and quantify anthocyanins in a vital dye extracted from the acai fruit (), adjust pH and osmolarity, and perform lyophilization to develop a new chromovitrectomy dye.

Methods: Three dye concentrations 10%, 25%, and 35% (equivalent to 100, 250, and 350 mg of lyophilized acai fruit pulp extract samples) were evaluated when diluted in 1 ml of phosphate-buffered solution (pH 7 and 300 mOsm). The dye was analyzed by mass spectrometry and high-performance liquid chromatography (HPLC) to identify and quantify anthocyanins molecules.
