(K-402) Design and Fabrication of a Synchronously Updated 3-D Source for Retinal Electrodiagnostic Testing

Introduction:: Our research focuses on the design, fabrication, and evaluation of Illuminex, a groundbreaking Synchronously Updated 3-D Source for Retinal Electrodiagnostic Testing. The current landscape of retinal electrodiagnostic testing poses challenges in In patient access. Current ERG test requires separate dedicated stimulus source for each type of ERG. This raises costs for healthcare facilities & lowers patient throughput. Illuminex aims to address these limitations by employing a modular design that can perform several ERG test, such as ffERG, mfERG, fERG, PERG, PPERG, PhNR ERG, Sectoral PhNR ERG, as well as eventually a “Clicker Free” Visual Field. This study aims to validate the effectiveness of Illuminex modules in improving testing accuracy, efficiency, and patient experience.

Materials and Methods:: In the design phase, we utilized computer-aided design (CAD) software to develop the modular structure of Illuminex. The design incorporated light diffusers, and an optimized light guide system in one hexagonal module. Fabrication was carried out using fused deposition modeling (FDM) 3D printing, allowing for rapid prototyping and iterative improvements. To evaluate the performance of Illuminex, we conducted extensive luminance testing using a calibrated complementary metal oxide semiconductor sensor and image analysis with MATLAB. The coefficient of variance in luminance across the entire viewing surface was quantified to assess uniformity.

Results, Conclusions, and Discussions::

Discussion: Through iterative design and fabrication, we have successfully inched forward towards the development of the Illuminex system, achieving significant advancements in retinal electrodiagnostic testing. Our findings demonstrate improved uniformity and precision in luminance measurement compared to previous methods. The modular design of Illuminex enables ease of assembly, modification, and scalability. Additionally, our evaluations have highlighted the system's potential to simplify testing procedures, reduce manual labor, and enhance diagnostic accuracy.

Conclusion: The design, fabrication, and evaluation of Illuminex have yet yielded promising results in the field of retinal electrodiagnostic testing. By addressing the limitations of existing methods, Illuminex offers a more efficient and reliable approach for assessing retinal function. Further validation and clinical studies are warranted to establish its effectiveness in diagnosing retinal conditions and monitoring disease progression. Illuminex has the potential to revolutionize the field of ophthalmology and improve patient care by providing a standardized, user-friendly, and accurate testing platform.
