optical coherence tomography system (OCT)

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.
Getting ready for ARVO 2017: New president, special OCT issueLearn about the latest updates from The Association for Research in Vision and Ophthalmology for 2017 and beyond.
Signal strength important factor when analyzing OCT scansOptical coherence tomography scans can be useful to follow glaucoma, but clinicians should be aware of scan quality.
Imaging, 27-gauge systems capture retina surgeons’ focusRetina surgeons considered 2015 to be an exciting time in the subspecialty in all areas and pointed to the availability and increased use of 27-gauge instrumentation as one of the real highlights of surgical retina.
Improvements in detecting and measuring glaucoma round out 2015As 2015 progressed, researchers reported better ways to detect glaucoma, measure the damage it is causing, and understand how that damage is affecting their patients’ lives. No single innovation revolutionized the profession, but a wide range of technologies became more available to clinicians.
Year brings advances in retinal imaging, screening, and gene/drug therapiesThe topics of special interest to retina specialists during 2015 include optical coherence tomography angiography (OCTA) and screening for retinopathy of prematurity (ROP). Important research is taking place to determine the etiology of angiogenesis, possibly leading to targeting therapies in age-related macular degeneration (AMD), ROP, and diabetic retinopathy.
