Brief Summary:
This study attempts to test capillary responses to various challenges without the need for iontophoresis (electrical current).

Condition or disease Intervention/treatment
Diabetes Retinopathy Vascular Pathology Device: Laser Doppler Flowmetry with topical acetylcholine and nitroglycerin

Detailed Description:
Studies of microvascular responsiveness often employ iontophoresis to fascilitate drug absorption. Iontophoresis is a confounding stimulus in such studies, and we are attempting to create tests of the microvasculature that do not require iontophoretic drug delivery.

Study Type : Observational
Estimated Enrollment : 20 participants
Observational Model: Defined Population
Primary Purpose: Screening
Time Perspective: Cross-Sectional
Time Perspective: Prospective
Official Title: Transdermal Application of Acetylcholine and Nitroglycerin Without Iontophoresis.
Study Start Date : June 2005
Estimated Study Completion Date : September 2005
