Background: Age-related macular degeneration (AMD), a condition of multifactorial origin, is a major cause of irreversible vision loss in industrialized countries. The dry late stage of the disease, known as geographic atrophy (GA), is characterized by progressive loss of photoreceptor cells and retinal pigment epithelial cells in the central retina. An estimated 300 000 to 550 000 people in Germany suffer from GA.

Introduction: This study aimed to compare changes in retinal oxygen saturation 1 month after femtosecond-assisted laser in situ keratomileusis (FS-LASIK) in Chinese adults with myopia using retinal oximetry.
Methods: In this prospective, observational, single-center cohort study, Chinese adults aged 18-45 years with myopia were categorized into four groups according to spherical equivalent (SE), with 66 eyes characterized as low myopia (LM -3.00D < SE ≤ -0.

Polarization is a property of light that describes the oscillation of the electric field vector. Polarized light can be detected by many invertebrate animals, and this visual channel is widely used in nature. Insects rely on light polarization for various purposes, such as water detection, improving contrast, breaking camouflage, navigation, and signaling during mating.

Background Studies have explored the application of multimodal large language models (LLMs) in radiologic differential diagnosis. Yet, how different multimodal input combinations affect diagnostic performance is not well understood. Purpose To evaluate the impact of varying multimodal input elements on the accuracy of OpenAI's GPT-4 with vision (GPT-4V)-based brain MRI differential diagnosis.
