OCT-based artificial intelligence for irregular cornea classification
Summary ­The current technology provides for an OCT-based artificial intelligence (AI) algorithm to improve classification and diagnosis between common corneal shape abnormalities including forme fruste (pre-clinical) keratoconus (FFK), contact lens related warpage, dry eye disease, and Fuch’s endothelial dystrophy. Technology Overview Keratoconus...

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
SummaryThe 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...

Aqueous Cell Differentiation in Anterior Uveitis Using OCT
Uveitis is the third leading cause of blindness in developed countries. The differential diagnosis of patients presenting ocular inflammatory conditions, such as anterior uveitis, is broad and includes infectious etiologies, systemic autoimmune disease, and malignancy. Currently, treatment is guided by clinical characteristics of the uveitis. (For...
