An OCT method to improve scleral lens fitting

Summary The current technology allows for accurate and objective 3-dimensional (3D) mapping of the external limbus, which could ultimately improve the process of scleral lens fitting. Technology Overview Rigid scleral lenses are difficult to fit to patients because they must rest on the eye but vault over the cornea and the limbus, which is the transition...

Postprocessing algorithms to minimize fixed pattern artifact and reduce trigger jitter in swept source OCT

Summary OHSU developed post-processing algorithms which could minimize fixed pattern artifact and reduce trigger jitter in swept source optical coherence tomography (SS-OCT). Technology Overview Swept-source OCT has advantages of less fringe washout and faster imaging speeds compared to conventional spectraldomain detection. Therefore, it is attractive...

Quantification of vascular abnormality with OCT angiography

Summary Current OCT techniques are limited in their ability to accurately detect vasculature changes, and patients with retinal vascular diseases often require more invasive intravenous contrast dye-based angiography procedures. The current technology is an OCT-based non-injection, dye-free method that allows for 3D visualization of superimposed structural...

Forward scanning vitrectomy OCT microprobe

Summary The practical employment of OCT probes in surgeries of solid organs or internal cavities has been limited by the lack of miniature forward-scanning probes. Dr. David Huang and colleagues have developed a small forward-scanning OCT vitrectomy probe that would allow for the incorporation of OCT into probe-guided procedures for a variety of organs. Technology...

Visual field simulation using OCT and OCT angiography

Summary Preventing glaucoma disease progression requires regular monitoring and timely treatment. However, current assessment of visual field loss is subjective and can be unreliable for monitoring small progressive vision loss. Accordingly, Dr. David Huang et al. developed an OCTA test that produces simulated visual fields. The test provides a more...
