Photostress Testing Device for Diagnosing Retinal Disease

Blog Article

Retinal diseases such as Age-Related Macular Degeneration (ARMD) affect nearly one in three elderly patients.ARMD damages the central vision photoreceptors in the fovea.The Photostress Test is a simple technique for testing Soft toys for the early effects of ARMD.Here, the illumination sources in a novel self-administered Photostress Testing device were modeled for safety and distribution in illumination software.

After satisfying the design constraints in the model, a prototype of the illumination system was fabricated and tested to confirm the modeling results.The resultant prototype can be used to aid in the diagnosis of Tanks/Jerseys retinal disease and is well within retinal safety levels.
