optical coherence tomography system (OCT)

OCTA brings understanding to managing diabetic eye diseaseOptical coherence tomography angiography (OCTA) is a promising new approach for visualizing retinal vascular pathology in eyes with diabetic eye disease that can be expected to have even greater utility in the future pending further enhancements.
Diagnosing and treating MacTel degenerative retinal diseaseIdiopathic macular telangiectasia (MacTel) is bilateral condition characterised by ectatic capillaries of the macula and atrophy of the neurosensory retina. Familiarity with the distinctive intraretinal cavitation on SD-OCT in type 2, the most common type, is key for correct diagnosis.
OCT imaging yields better visualizationFuture increases in imaging speed will improve performance and functionality for OCT and OCT angiography (OCTA), said James Fujimoto, PhD.
How wide-field SS-OCT expands spectrum of normal peripheral retinaWide-field retinal imaging can be performed using a commercially available swept-source optical coherence tomography (SS-OCT) platform (DRI OCT Triton, Topcon) and only the internal fixation light for patient navigation provided detailed images of both normal and pathologic peripheral retinal findings.
How adaptive optics will change retinal imaging
How adaptive optics will change retinal imagingAdaptive optics could allow clinicians to monitor the progression of retinal diseases cell-by-cell, according to Jacque Duncan, MD.
Multifunctional OCT system approval simplifies imagingA newly approved system (3D OCT-1 Maestro, Topcon) combines a high-resolution, color, non-mydriatric retinal camera with the latest spectral-domain optical coherence tomography (OCT) technology, and stands out for its versatility as well as its quality and ease of use.
Multimodal imaging approach useful in treatment of uveitisSuccessful imaging for the group of diseases known as uveitis depends on the specific underlying etiology. Tailoring the imaging approach using a variety of imaging methods, which are often complementary, can yield the maximum amount of information. This approach is useful not only for diagnosis and management of patients, but increasingly in clinical trials.
New technology takes invisibility cloak off in retinal imaging
New technology takes invisibility cloak off in retinal imagingNew imaging technologies, such as ultra-wide-field fluorescein angiography and optical coherence tomography angiography, are providing more details about retinal diseases than previous imaging technologies, leading to better understanding of disease processes.
The case of the blurred disc marginsA 16-year-old female was scheduled for her periodic ophthalmic evaluation to update her spectacle lens prescription. At the visit, she reported a history of migraines, but the remainder of her personal and family medical history was non-contributory. She took no medications and had a history of low hyperopic refractive correction.
Handheld polarizing filter augments corneal imaging with simple approachUse of a handheld circular polarizing filter to intercept afferent and efferent light from a slit lamp or operating microscope highlights corneal structures that are otherwise invisible or barely seen.
