Presentation Transcript

  1. How to interpret the HRT Vellore Parthasarathy

  2. Overview • Scanning LASER Ophthalmoscopy • Numerical values • Technological assumption - Reference plane Contour line Good quality images

  3. Reference plane Papillomacular bundle • 350-356 degrees • 50 nm from retinal surface

  4. What to look for first? • Image centration • Contour line • Topographic standard deviation • Other clues blood vessels image borders, illumination.

  5. Topographic progression analysis • Red for progression • Green for anterior displacement

  6. Summary Image Quality Top 5 parameters Moorfield’s Regression Trend report

  7. Remember ! The name of the game

  8. Follow up over time Thank you !
