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 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.
Ebola may leave retinal scarThe Ebola virus may leave a retinal scar specific to the disease, according to researchers. “The distribution of these retinal scars or lesions provides the first observational evidence that the virus enters the eye via the optic nerve to reach the retina in a similar way to West Nile virus,” said Dr Paul Steptoe of the Royal Liverpool Hospital, in a press release.
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.
New concepts about macular edema emerge from modern imaging studiesVolume-rendered optical coherence tomography (OCT) imaging allows new insight into retinal vascular flow and morphological changes in eyes with macular edema (ME), and the information obtained is the basis for new ideas about the pathogenesis of ME and therapeutic intervention, according to Richard F. Spaide, MD, Vitreous Retina Macula Consultants of New York.
How OCT innovations are changing glaucoma careOptical coherence tomography (OCT) is swiftly improving the diagnosis of glaucoma, according to Joel S. Schuman, MD, who helped invent the technology.
Introducing 3-D OCT to live surgery
Introducing 3-D OCT to live surgeryThe advent of three-dimensional optical coherence tomography to live surgery may bring greater clarity to how ophthalmologists visualize structures and how they operate.
