Perseus Specular Microscope: Automated and Non-Contact Endothelial Analysis
The Perseus specular microscope stands out for its ability to provide detailed and precise analysis of the corneal endothelium in a fully automated manner. This modern device is designed to offer maximum comfort for patients and remarkable ease of use for eye care professionals. Equipped with the latest hardware and software technologies, the Perseus is a top choice for reliable and rapid assessment of corneal health.
Comfort and Ease of Use
The Perseus is characterized by its low light intensity, ensuring optimal comfort for patients during the examination. Its ergonomic design is enhanced by a user-friendly interface, controlled via an intuitive touchscreen. This interface simplifies alignment and examination parameter management, allowing users to focus on results without being distracted by complex manipulations.
Automated Analysis and Precision
The Perseus specular microscope enables non-invasive and automated endothelial analysis, with an impressive capability of counting up to 400 cells per image. Thanks to auto-alignment and vertex-based analysis, the Perseus produces exceptionally clear endothelial images within seconds. The advanced technologies used in the development of this device include a high-quality CCD camera and a sophisticated software algorithm to ensure perfectly focused images. Additionally, an advanced processing tool is available for images from severely damaged eyes.
Wide Measurement Area and Detailed Analysis
The Perseus offers a wide measurement area that facilitates the counting of a large number of cells from a single acquisition. The analysis is conducted across seven distinct zones, including a central point and six peripheral points, allowing a comprehensive and detailed view of the corneal endothelium. The high magnification function enables detailed examination of each cell, with zoom capabilities for in-depth visualization of cell boundaries. This feature is particularly useful for manual editing of cells when the image quality is not perfectly recognized by the system.
Advanced Software Features
The Perseus software is designed to evaluate all relevant endothelial data, including:
Total number of cells counted
Cell density (number of cells per mm²)
Average cell size analyzed
Standard deviation of cell size
Coefficient of variation
Statistical distribution of cell sizes (polymegathism) and shapes (pleomorphism)
Data management is integrated within the Perseus software, with options to share data via a network with existing archives or transfer it to a DICOM (Digital Imaging and Communications in Medicine) compatible server.
Pachymetry Assessment
In addition to endothelial analysis, the Perseus performs non-invasive pachymetry with each image acquisition. This feature adds an extra dimension to corneal evaluation, essential for detecting and monitoring changes in corneal thickness.
Additional Features
The Perseus is also equipped with fixation targets to facilitate measurements in the peripheral areas of the cornea, which is particularly useful for detailed assessments in cases of specific corneal pathologies. The system also allows for the creation of image mosaics when acquisitions are made from different positions, providing a comprehensive overview of the corneal endothelium.
