      Drusen Volume as a Predictor of Disease Progression in Patients With Late Age-Related Macular Degeneration in the Fellow Eye
      Purpose : Increasing drusen volume was proposed to be a predictor of disease progression in age-related macular degeneration (AMD). In patients with late AMD in one eye, the fellow eyes without neovascularization are known to be at higher risk of developing exudative AMD. We evaluated the relationship between drusen volume in these fellow eyes and their progression to late AMD. Methods : A retrospective analysis included fellow eyes with drusen associated with ...

    1. With CIRRUS FastTrac, I can place a highest resolution 20x B-Scan precisely on the area I am treating at each successive visit to see the fine details of the patient’s response to treatment...It’s also very helpful for removing any eye motion from the larger cube scans without disturbing my patient flow because it works so quickly. My initial experience is that FastTrac is about 30 percent faster than other tracking methods I have used.
