Imaging diagnosis plays a fundamental role in avian medicine. However, there are few publications regarding its use in ophthalmology. Seabirds, in particular, present a peculiar ecology since their lives take place in very diverse environments: the aquatic, the terrestrial, and the aerial. This fact implies a series of adaptations at a visual level that are necessary for adequate interaction with the environment. Therefore, knowledge of eye particularities is of great importance for the scientific community since it allows us to deepen our understanding of the ocular anatomy and biology of these animals, which are increasingly present in veterinary and wildlife centers. In our study, we performed a morphometric analysis of the ocular bulb and its internal structures in the puffin ) using advanced imaging techniques such as CT.

Reaching the back of the eye without invasive intraocular injections is still nowadays challenging. Luckily, the nanotechnology can help in improving the effectiveness and the patient compliance and, ultimately, the therapeutic success rate. The development and characterization of ophthalmic (nano)formulations benefit from the implementation of ex vivo models, that allow to disclose the formulation behaviour once in contact with biological tissues and consequently its optimization.

Background: Magnetic resonance imaging (MRI) is a crucial tool for visualizing orbital structures and detecting eye pathologies. However, manual segmentation of orbital anatomy is challenging due to the complexity and variability of the structures. Recent advancements in deep learning (DL), particularly convolutional neural networks (CNNs), offer promising solutions for automated segmentation in medical imaging.

Occupational silicosis caused by long-term inhalation of silica is a serious public-health problem in the world and is known to be a risk factor for the development of dementia. However, the progression of silicosis, including its impact on the brain and its relationship with β-Amyloid (Aβ), the early biomarker of Alzheimer's disease, remains unclear. In this study, we categorized silicosis into four stages in a mouse model and employed [F] AV45 PET imaging to quantify Aβ deposition across 19 cerebral sub-regions.

In modern small-gauge vitreoretinal surgery, the surgeon navigates the occutome and a rigid optical fiber endo-illuminator into the posterior segment. Effective endo-illumination is crucial for minimizing surgical risks and ensuring optimal outcomes by enhancing the visibility of ocular structures. Traditionally, endo-illuminators in vitreoretinal surgery have relied on xenon light sources provided by the vitrectomy system.

Purpose: We present a case of transmuscular migration of a solid encircling silicone band through all four rectus muscles.
Observations: A 33-year-old male with high myopia presented with a progressively worsening subclinical peripheral rhegmatogenous retinal detachment in his left eye. An encircling silicone band (#240) was placed anterior to the equator, and 5-0 polyester sutures (Ethicon, Inc.
