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 for the early effects Necklace of ARMD.Here, the illumination sources in a novel self-administered Photostress Testing device were modeled for safety and distribution in illumination software.After Candles 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 retinal disease and is well within retinal safety levels.
