High-Resolution Ultrasound Imaging of the Retina and Choroid for Detection on Age Related Macular Degeneration

NCT00277784 · Status: COMPLETED · Type: OBSERVATIONAL · Enrollment: 40

Last updated 2008-03-07

No results posted yet for this study

Summary

The macula is the site of central vision within the retina. The retina is oxygenated by the underlying choroid. These tissues are less than 1 mm thick in total. While optical techniques can reveal much about the structure of the retina, ultrasound allows imaging of the choroid and deeper tissues. This study will investigate use of high frequency (20 MHz) ultrasound for imaging of the retina and choroid in patients with age-related macular degeneration, a prime cause of blindness. The investigation will involve use of novel post-processing methodologies to achieve maximum resolution of the fine tissue structures involved in this disease.
