Right-angle microprisms inserted into the mouse neocortex allows for deep imaging of multiple cortical layers with a viewpoint typically found in slice. One-millimeter microprisms offer a wide field-of-view (~900 μm) and spatial resolutions sufficient to resolve dendritic spines. We demonstrate layer V neuronal imaging and neocortical vascular imaging using microprisms.

Here, we show how to analyze dendritic routing of Drosophila medulla neurons in columns and layers. The workflow includes a dual-view imaging technique to improve the image quality and computational tools for tracing, registering dendritic arbors to the reference column array and for analyzing the dendritic structures in 3D space.

This article demonstrates how to culture Arabidopsis thaliana seedlings in a two-layer microfluidic platform that confines the main root and root hairs to a single optical plane. This platform can be used for real-time optical imaging of fine root morphology as well as for high-resolution imaging by other means.

FAQs
The boundary becomes discernible through differences in optical behavior between adjacent corneal tissues. In vivo confocal microscopy and anterior-segment optical coherence tomography use optical sectioning to isolate depth-specific information, while tissue reflectivity helps distinguish Bowman’s layer from the epithelium and stroma. This combination supports noninvasive evaluation rather than relying only on clinical surface appearance.
Thickness, continuity, and surface integrity provide different structural readouts. Thickness measurements characterize the layer quantitatively, whereas continuity and surface integrity indicate whether its interface remains uninterrupted or altered. Examining these features together gives imaging a broader role than locating Bowman’s layer alone, because the resulting structural profile can be related to corneal organization and optical clarity.
Although imaging does not directly measure biomechanics, structural assessment of Bowman’s layer provides information about an interface that contributes to corneal structure. Relating its thickness, continuity, and surface integrity to conditions such as keratoconus or corneal ectasia can help researchers examine how structural changes accompany differences in corneal biomechanics and optical performance.
A focused assessment examines three features: the layer’s measured thickness, its continuity across the imaged region, and the integrity of its surface. These observations can be interpreted together to characterize structural changes rather than treating the boundary as a simple landmark. Repeating the assessment may help identify disease progression or changes after treatment.
Both modalities provide high-resolution assessment, but the overview does not assign them identical measurement strengths or clinical roles. Their shared contribution is depth-resolved visualization based on optical sectioning and tissue reflectivity. Accordingly, either approach can support noninvasive distinction of Bowman’s layer and evaluation of its structural features in appropriate corneal investigations.
Clinical use is especially relevant when corneal structure may be abnormal, including keratoconus, corneal ectasia, scarring, or changes following refractive surgery. Assessing Bowman’s layer in these settings can add structural information to the evaluation of the cornea. The findings may support diagnosis while also providing a basis for comparing disease-related or postsurgical changes.
Serial imaging allows investigators or clinicians to compare Bowman’s layer across examinations using features such as thickness, continuity, and surface integrity. Changes in these measurements can contribute to monitoring corneal disease progression or treatment response. This longitudinal perspective also supports research into how alterations at the layer relate to broader changes in corneal structure and optical clarity.
