Imaging/Diagnostics News

Ellex Medical Lasers launched Eye Prime diagnostic ultrasound technology for evaluating pathology of the eye, according to a press release.

VANCOUVER, British Columbia — Using good-quality macular-centered fundus photographs and serum samples, a newly designed deep learning system could accurately estimate hemoglobin A1c levels, according to a speaker here.

Eyenuk has launched its EyeScreen Human + AI Diagnostic Service for diabetic retinopathy, according to a press release.

Purchasing a stand-alone laser system or a laser system with a slit lamp adaptable delivery system is a choice that is specific to your practice. Having worked with both types, it really comes down to cost, space and office workflow in determining what will work best for you.

OCT is based on the principle of Michelson interferometry. It uses a near infrared wavelength source for visualization of ocular structures. There are two different types of OCT systems based on type of processing: time domain and spectral domain. SD-OCT provides faster acquisition and higher resolution as compared with TD-OCT. It takes 26,000 A-scans per second with a rate of 256 to 1,024 frames per second. The depth resolution in tissue is 5 µm, and the transverse resolution is 15 µm. There have been various indications for SD-OCT in ophthalmology. The pupil can be assessed by SD-OCT, but there have not been any reports on this. We utilized SD-OCT to visualize the pupil after single-pass four-throw pupilloplasty, as seen in Figure 1.

FORT LAUDERDALE, Fla. — A subanalysis of the DISCOVER study showed intraoperative OCT integration with 3-D digital surgical visualization is feasible and posed ergonomic and surgical visualization efficiency advantages over conventional microscope systems, according to a speaker here.

FORT LAUDERDALE, Fla. — The development of a no-contact, handheld OCT-A probe has allowed the first images to be captured of nonsedated infants, according to a speaker here.

FORT LAUDERDALE, Fla. — Patients with intermediate age-related macular degeneration treated with intravitreal aflibercept injections did not experience improved rates of non-conversion to neovascular age-related macular degeneration after 12 months of treatment, according to a speaker here.

ATHENS, Greece — Greece has more than 200 inhabited islands, poorly connected with the mainland, where prevalently older people live to an advanced age. Many of them could benefit from an invention of Iordanis Chatziangelidis, MD: a remotely controlled slit lamp that will allow islanders to be examined by an ophthalmologist at a distance, saving on expensive and cumbersome traveling.

Swept-source OCT with the Topcon DRI Triton system provides high-resolution imaging of the choroid, allowing visualization of previously unknown disease manifestations, according to one researcher. The combination of high speed and longer wavelength ensures better, deeper penetration and fast, clear image acquisition, resulting in near-histologic resolution of the choroidal structures.
