Optical coherence tomography
- 1. Optical Coherence Tomography OCT Dennis M. West, CRA
- 15. Fast OCT 3 scan The same eye scanned with maximum resolution
- 22. The over-all retinal profile
- 24. a pigment epithelial detachment is causing the convexity
- 25. Aside from the retinal detachment, notice the underlying concave curvature of the retina, suggesting the long eye of a significant myope
- 28. Macular cyst
- 29. Macular hole, stage 2
- 30. Macular hole, stage 3
- 31. Macular hole, stage 4, operculum suspended by the hyaloid membrane
- 34. Serous retinal pigment epithelial detachment (PED)
- 37. Cystoid macular edema cause by diabetic maculopathy
- 52. Each of the six scans can be reviewed by clicking on the slider bar to the left, and any or all of them can be printed out for the patient's record
- 79. When you click on the thumbnail at the bottom, the current set of scans is displayed in the windows above.
