Pitt Optical Coherence Tomography Laboratory

The Pi group at the University of Pittsburgh is dedicated to the advancement and application of Optical Coherence Tomography (OCT) in ophthalmology. Our focus is on developing and improving OCT technology to improve the detection, diagnosis, and treatment of ocular diseases, ultimately leading to better patient outcomes and quality of life. 

OCT has become an indispensable tool due to its ability to offer non-invasive, micron-resolution, dye-free, and 3D imaging in vivo. As a result of its ability to provide detailed and accurate images of the eye, OCT is widely used in clinics and research to image living animals and humans. It has revolutionized the diagnosis and management of various ocular conditions such as glaucoma, age-related macular degeneration, and diabetic retinopathy. 

The emerging extensions of OCT encompass OCT angiography (OCTA), polarization-sensitive OCT (PS-OCT), Doppler OCT, full-field OCT (FF-OCT), and OCT oximetry. These advancements have broadened the scope and applications of OCT across various fields, including ophthalmology, cardiology, dermatology, neuroscience, and other fields.


We are currently looking for highly motivated individuals from diverse backgrounds to join our team as students, technicians, and postdocs. We offer a dynamic and collaborative environment that provides opportunities for growth and development, as well as access to cutting-edge technology and resources. 

If interested, please contact us with your CV to discuss potential opportunities.

Visible-light OCT (Vis-OCT)


Dr. Pi published a first-author paper in IOVS

April 15, 2023

We used vis-OCT to image rat retinas before and after ONT and characterized the neurodegenerative and vascular impairments by studying retinal layer thickness, blood vessel density, and blood oxygen saturation.
