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...

Software for deep learning-based inference of biomarker distribution in cancer samples

Summary Multiplexed tissue imaging (MTI) is a powerful tool for cancer pathology, but it is also expensive, which has limited its availability for underserved communities, particularly in the developing world. The current software uses hematoxylin & eosin (H&E) staining, which is more widely available, to predict oncology biomarker distribution,...

Cell-permeant and water-soluble rhodamine dyes for quantitative imaging applications

Summary Rhodamines are a class of fluorescent proteins (FP) that stand out for their higher photostability and brightness as well as easier synthesis compared to other FPs; however, classic rhodamines generally have poor water solubility and tend to aggregate in an aqueous environment. Oregon Health & Science University researchers have developed...

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...
