Purpose 

Theia Imaging is developing easy-to-use, compact, portable eye imaging systems for use in infants, children and those unable to cooperate for conventional tabletop clinical eye diagnostics.

Our mission is to bring access to advanced ophthalmic imaging diagnostics to populations unable to access conventional tabletop clinical imaging. This spans the range of human eye disease from: retinopathy of prematurity to diabetic retinopathy, glaucoma, age-related macular degeneration, as well as inherited retinal diseases.

Beyond retinal diagnostics, our advanced imaging technologies also provide non-invasive access to neurological information. The eye is often referred to as the “window to the brain”, as retina and optic nerve head are direct extensions of brain tissue. Thus, the microanatomy and microvascular flow within the eye can provide valuable information about brain development and brain disease.

Theia’s proprietary imaging technology enables access to structural and angiographic images of retina in populations that were previously unreachable, providing access to data that will revolutionize the diagnosis and monitoring of retinal and neurological diseases in these populations.

Introducing the T1 Investigational System

  • Faster: Leveraging next-generation swept source technology, the T1’s 300kHz A-scan rate provides an order of magnitude reduction in image acquisition time, simplifying image capture and enabling dense volume sampling, even with squirming subjects.
  • Lighter: At under 350 grams (12 oz), the T1 imaging probe weighs in at less than a quarter of the weight of competitive devices, eliminating hand fatigue and providing an extra factor of safety for imaging delicate subjects.
  • Easier: The T1’s revolutionary ergonomic design and an integrated pupil camera with NIR illumination simplify image alignment without a bright, uncomfortable stimulus.

Example images from the T1 device:
peripheral scan (A), macular scan (B), en face retina view (C) and pupil camera view (D).

Leadership

Theia Imaging was formed in the Spring of 2020 by three founders with pioneering expertise in translational research, pediatric eye care and ophthalmic diagnostics.

Hafeez Headshot

Hafeez Dhalla, PhD, MBA

Founder & Chief Executive Officer

  • PhD in Biomedical Engineering, Duke University
  • Postdoctoral Fellowship, Massachusetts Institute of Technology
  • MBA, Quantic School of Business and Technology

Dr. Dhalla’s expertise spans the academic, research and commercial worlds of biomedical optics and medical imaging. Before co-founding Theia Imaging, he lead the development of multiple FDA-cleared ophthalmic devices as an engineer and consultant. Dr. Dhalla also holds an academic appointment in Biomedical Engineering at Duke University.  His commercial and academic research has lead to 11 issued and pending patents.
