Optical Coherence Tomography Angiography Features in Patients with Untreated Obstructive Sleep Apnea

Department(s) or Division(s)


The purpose of this study is to assess and characterize the retinal blood vessels (vasculature) in patients with untreated Obstructive Sleep Apnea (OSA), using a noninvasive imaging system called the optical coherence tomography angiography (OCTA).

Obstructive sleep apnea (OSA) is a sleep disorder associated with other chronic systemic diseases such as heart disease and diabetes, as well as several eye conditions such as wet age related macular degeneration (AMD) and diabetic macula edema.  Color fundus photography involves noninvasive capturing of a picture of the back of the eye without the use of dye. Few studies have attempted to evaluate the retinal vasculature in patients with OSA using color fundus photos, with mixed results.

The optical coherence tomography angiography (OCTA), is a quick, non contact imaging technique which does not require the injection of any dye, to look at the structural and blood flow of the retina.

Patients may qualify to take part in this research study because it is suspected that they have undiagnosed OSA or are an otherwise healthy individual.
