2. Introduction Principle Types Procedure and analysis Clinical applications Limitation

3. Principle

4. Types

5. Procedure Explain the procedure Patient should be seated comfortably for a good scan. NON Contact- blink C ontact- topical anesthesia coupling fluid used Internal fixation target is used to keep eye straight

6. Image analysis

7. Clinical applications

8. To study the normal endothelium morphology. To diagnose and study pathological changes in corneal endothelial diseases. Eye banking- assessment of donor cornea status. Pre operative endothelial health – surgery decision making. Research and monitoring of epithelium in below

9. Corneal endothelial disorders F uch’s endothelial dystrophy Posterior polymorphous dystrophy Iridocorneal endothelial disorder Lattice corneal dystrophy DM tear

10. Fuch’s endothelial corneal dystrophy

11. Ice syndrome

12. Lattice stromal dystrophy

13. DIABETICS

14. Surgery Endothelial cell loss PHOCOEMULSIFICATION 5-8% in 6 months 10.5% at 1 year SICS 4.21% at 6 weeks PKP 11%+-20% at 6 months 20% at 1 year DALK 14.2%+-11.7% at 1 month 8.6% at 1 year DSAEK 34%-+22% at 6 months Same at 1 year DMEK 35% at 6 months 38% at 1year PPV 9%+-14.6% at 3 months TRABECULAECTOMY 7%

15. summary Explain the procedure to the patient Image the region 3x at the same sitting Use same analysis method during follow-up To obtain maximum efficacy count 75-100 cells or more
