Annular Array Ultrasound in Ophthalmology

Summary

The objective of this research is to improve the care of ocular disease and disorders, in particular the changes in the eye associated with diabetes, by providing clinicians with dramatically improved ultrasonic images of the entire eye. The research combines advanced high-frequency, high-resolution ultrasonic annular arrays transducers with new processing techniques designed to overcome several limits that have been reached with conventional high frequency ultrasound systems. The investigators propose that diagnosis of eye diseases using annular arrays can be more effective than the conventional ultrasound images by at least 50%; i.e., that for every 2 posterior vitreous detachments detected conventionally, 3 will be detected with the annular arrays.

Interventions

PROCEDURE

annular array ultrasound exam

For this research study you will be asked to sit in a chair. You will be given 2 drops of a numbing solution. The ultrasound camera will be enclosed in a sterile membrane and will be placed gently upon your eye. You may be asked to gaze at a light source while measurements are being made. The procedure will last about 10-15 minutes from start to finish.
