A Sneaky Culprit: Secondary Infectious Keratitis Due to Brevundimonas diminuta.
Eye Contact Lens
January 2025
Medical College of Wisconsin, Milwaukee, WI.
Purpose: To describe a rare case of infectious keratitis secondary to Brevundimonas diminuta, a gram-negative bacillus with fluoroquinolone resistance and rare clinical isolation.
Methods: A 50-year-old man with contact lens overuse presented with a large corneal ulcer and hand motion visual acuity. Initial treatment with fortified topical tobramycin and vancomycin yielded slow improvement, and initial culture grew Staphylococcus epidermidis, Staphylococcus hominis, and Corynebacterium bovis.
Identification of diabetic retinopathy lesions in fundus images by integrating CNN and vision mamba models.

Department of Radiology, Yantaishan Hospital, Yantai, Shandong, China.
Diabetic retinopathy, a retinal disorder resulting from diabetes mellitus, is a prominent cause of visual degradation and loss among the global population. Therefore, the identification and classification of diabetic retinopathy are of utmost importance in the clinical diagnosis and therapy. Currently, these duties are extensively carried out by manual examination utilizing the human visual system.

Retinopathy with Vitamin E Deficiency (RVED) is a familial disease in the English Cocker Spaniel (ECS) dog breed. Ophthalmic abnormalities observed in RVED-affected ECS include lipofuscin granule deposition within the tapetal fundus and subsequent retinal degeneration resulting in visual deficits. Affected dogs may also exhibit neurological signs that include ataxia and hindlimb proprioceptive deficit.

Polarization optical coherence tomography optoretinography: verifying light-induced photoreceptor outer segment shrinkage and subretinal space expansion.
Neurophotonics
January 2025
University of Illinois Chicago, Department of Biomedical Engineering, Chicago, Illinois, United States.
Significance: Stimulus-evoked intrinsic optical signal (IOS) changes in retinal photoreceptors are critical for functional optoretinography (ORG). Optical coherence tomography (OCT), with its depth-resolved imaging capability, has been actively explored for IOS imaging of retinal photoreceptors. However, recent OCT studies have reported conflicting results regarding light-induced changes in the photoreceptor outer segments (OSs), with both elongation and shrinkage being observed.
