Article Synopsis
  • Myopia, or nearsightedness, is becoming more common in children, and its potential link to lack of sleep is being explored, though results have varied.
  • A systematic review of 657 articles narrowed down to 40 studies and found that insufficient sleep significantly increases the prevalence of myopia and high myopia in children.
  • The study suggests that ensuring children get enough sleep, along with encouraging outdoor activities and limiting close-up work, is important for reducing the risk of developing myopia.

Accurate detection and timely care for patients with high myopia present significant challenges. We developed a deep learning (DL) system enhanced by a self-supervised learning (SSL) approach to improve the automatic diagnosis of myopic maculopathy (MM). Using a dataset of 7,906 images from the Shanghai High Myopia Screening Project and a public validation set of 1,391 images from MMAC2023, our method significantly outperformed conventional techniques.

Article Synopsis
  • Excessive screen exposure is linked to health concerns, particularly affecting aging in middle-aged and elderly individuals, as studied among adults over 45 in Shanghai.
  • The study found that longer screen time correlated with an increased retinal age gap, meaning that greater screen use made people's eyes appear older than their actual age.
  • Sleep onset time played a crucial role in this relationship, suggesting that delaying sleep due to screen use worsened the impact on retinal aging; hence, reducing screen time, especially before bed, could help mitigate these effects.

Visual impairments and blindness are major public health concerns globally. Effective eye disease screening aided by artificial intelligence (AI) is a promising countermeasure, although it is challenged by practical constraints such as poor image quality in community screening. The recently developed ophthalmic foundation model RETFound has shown higher accuracy in retinal image recognition tasks.

Article Synopsis
  • The study evaluated the accuracy and consistency of self-service fundus photography versus traditional fundus photography done by experienced professionals.
  • Conducted with 65 participants in Shanghai, the research ensured subjects had no eye conditions that could affect imaging quality and used statistical methods to analyze the results.
  • Findings showed no significant difference in imaging repeatability between the two methods, suggesting that self-service fundus photography could be effective for large-scale eye disease screening.

Article Synopsis
  • Researchers developed a deep learning-based AI tool for diagnosing diabetic retinopathy (DR) in patients with cataracts using infrared fundus images at Shanghai General Hospital.
  • The study involved analyzing over 10,000 images from diabetic patients, successfully achieving impressive accuracy rates, including 100% for DR grading and diagnosis.
  • The AI software demonstrated high sensitivity (96.3%) and specificity (90.0%), proving its potential to enhance DR screening efficiency in clinical and community contexts.

Given the high incidence and prevalence of myopia, the current healthcare system is struggling to handle the task of myopia management, which is worsened by home quarantine during the ongoing COVID-19 pandemic. The utilization of artificial intelligence (AI) in ophthalmology is thriving, yet not enough in myopia. AI can serve as a solution for the myopia pandemic, with application potential in early identification, risk stratification, progression prediction, and timely intervention.

Myopia is a significant global health concern and affects human visual function, resulting in blurred vision at a distance. There are still many unsolved challenges in this field that require the help of new technologies. Currently, artificial intelligence (AI) technology is dominating medical image and data analysis and has been introduced to address challenges in the clinical practice of many ocular diseases.

Isoegomaketone is a water-soluble natural ketone compound that is commonly present in and . At present, it is known that isoegomaketone has a wide range of pharmacological activity, but there has been no thorough investigation of its potential targets. As a result, we examined the potential targets of isoegomaketone using the network pharmacology approach.
