Federal University of São Paulo

Status: Completed

Conditions: HIV Infections; Acquired Immunodeficiency Syndrome

BRA-713/06

Details and patient eligibility

About

The purpose of this study is to assess retinal nerve fiber layer thickness and macular thickness measured with optical coherence tomography (OCT) on patients infected by HIV virus without ocular manifestations and to correlate these results with perimetric findings assessed by frequency doubling technology perimetry (FDT).

Enrollment: 90 estimated patients

Sex: All

Ages: 21 to 60 years old

Volunteers: Accepts Healthy Volunteers
