OCT Angiography Opens Eyes

Facebook X LinkedIn Email
The U.S. ophthalmology market over the past year has seen the first wave of commercial optical coherence tomography angiography systems, but this technology must overcome certain limitations before reaching ‘gold standard’ status.

Dr. Daniela Ferrara, an assistant professor of ophthalmology at Tufts University School of Medicine in Boston, began researching retinal diseases in 1998. Age-related macular degeneration (AMD), a leading cause of blindness in elderly individuals of European descent, has been a recurring topic in her research. However, it was not until about two years ago — when Ferrara started testing prototype optical coherence tomography angiography (OCT-A) devices — that she saw just how much at the back of her patients’ eyes had been escaping her own eyes. For example, Ferrara...Read full article

    ophthalmology
    Ophthalmology is a branch of medicine that focuses on the anatomy, physiology, and diseases of the eyes and visual system. Ophthalmologists are medical doctors who specialize in the diagnosis, treatment, and prevention of eye disorders and diseases. They are trained to provide comprehensive eye care, including medical, surgical, and optical interventions. Key areas within ophthalmology include: General eye care: Ophthalmologists perform routine eye examinations to assess visual acuity,...
    optical coherence tomography angiography
    Also known as OCT-A, optical coherence tomography angiography is an imaging technique that uses light waves to measure changes in the reflectance characteristics, enabling the the quantitative analysis of vasculature. Primarily used in ophthamology, OCT-A is a noninvasive alternative to dye-based techniques for blood vessel imaging, such as indocyanine-green angiography and fluorescein angiography.
    optical coherence tomography
    Optical coherence tomography (OCT) is a non-invasive imaging technique used in medical and scientific fields to capture high-resolution, cross-sectional images of biological tissues. It provides detailed, real-time, and three-dimensional visualization of tissue structures at the micrometer scale. OCT is particularly valuable in ophthalmology, cardiology, dermatology, and various other medical specialties. Here are the key features and components of optical coherence tomography: Principle of...
