Ophthalmic imaging is an integral part of diagnostic procedures evaluating eye conditions. It enables ophthalmologists to image actual living tissue deep in the human eye at microscopic resolution and thus provides the basis for treatments of eye diseases. Optical coherence tomography, or OCT, is the method of choice for ophthalmologists […]
OCTA Tutorial: How does OCT Angiography Work? OCTA, also known as OCT angiography, is a non-invasive and dye-free imaging technique that can be used to visualize blood flow in tissues in 3D. It is a variant of optical coherence tomography (OCT), an optical imaging modality first applied in ophthalmology. OCT […]
Expedition into the Eye >> Learn how OCT is transforming our understanding of the eye, from tear film to photoreceptors. The eye is a delicate yet intricate structure, making it challenging territory to explore. With the emergence of optical coherence tomography (OCT) over the past 25 years, researchers and […]
OCT as Optical Biopsy in Dermatology Skin is the largest organ of the body, possessing an amazing ability to heal itself even after considerable damage. As our primary barrier against microbes and the elements, it is key that we understand the dermal repair process and how to speed it. OCT […]
