This clinical trial studies anal human papillomavirus (HPV) tests in screening for cell changes in the anus in patients with human immunodeficiency virus (HIV). Screening tests may help doctors find cancer cells early and plan better treatment for anal cancer. Completing multiple screening tests may help find the best method for detecting cell changes in the anus.
NCT01546766
The basic objective of this project is to test a modification of existing technology for monitoring the responses of the pupil to light as a method for detecting regional losses of function of the retina. The "instrument" consists of a commercially available set of goggles that monitor the eye positions and pupils using infrared light and small cameras. The signals from the monitoring cameras are collected in a computer that records how their pupils have responded to each lighting condition. Because diabetics develop damage initially to certain parts of the retina before they have more serious damage, the ultimate goal of this research is to develop a simple, noninvasive, rapid method for widespread screening of diabetics in order to identify those who may require medical attention and/or therapy for diabetic retinopathy.
