OCT

A study suggests that small hyperreflective retinal foci (HRF) on OCT images, linked to activated microglial cells, could serve as a valuable marker for monitoring neuroretinal inflammation and progression in age-related macular degeneration.

The NHS is expanding the use of optical coherence tomography to enhance diabetic eye care, aiming to improve early detection of diabetic retinopathy and reduce the backlog of hospital appointments.

A recent cohort study revealed low adoption of FDA-approved AI-based diabetic retinopathy detection, with less than 5% of diabetic patients receiving ophthalmic imaging. Researchers emphasize the need for improved awareness, cost-effectiveness, and integration to increase diabetic retinopathy screening rates.

Peking University researchers have developed a deep learning-based, noninvasive choroidal angiography method that enables detailed 3D visualization of choroidal vessels from OCT scans. This technique could improve diagnostics for retinal diseases like macular degeneration, offering a safer alternative to traditional methods.

Researchers find a strong link between Alzheimer's disease and retinal thinning

In a study, a team of UCLA investigators detail a deep-learning model pre-trained on 2D scans that accurately predicts disease-risk factors from 3D medical-scan modalities.

The award from the National Institutes of Health will enable a team of researchers to investigate Alzheimer and Parkinson progression through the eye.

Ophthalmologists can use OCT to find the early signs of disease

The study helped identify predisposing factors for severe SANS in astronauts.

A team of researchers in China examined the difference and relationship between optical coherence tomography and optical quality analysis system parameters induced by compound electrolyte intraocular irrigating solution or Ringer lactate solution during uncomplicated cataract surgery.

The nOCT allows for detailed visualization of the brain's vascular anatomy.

Researchers train deep learning model on OCT scans to ID patients eligible for GA trials.

The company’s Spectralis OCTA module with SHIFT technology offers a tool for the diagnoses and management of retinal diseases.

Scientists from the International Centre from Translational Eye Research used multiwavelength laser Doppler holography to assess blood flow in various layers of the human retina in vivo, which may impact the diagnosis of circulatory disorders.

The mapping method revealed prominent microscopic abnormalities consistent with diabetic retinopathy.

The company noted its OCT reference database now offers a library of 870 healthy eyes, more than tripling the previous versions.

A team of researchers are unraveling the mysteries of ocular pathologies by visualizing the fiber structure of the sclera, the outermost eye layer.

Joseph Izatt was a skilled researcher and inventor who played a foundational role in the development of optical coherence tomography.

The collaboration will bring automated, AI-powered OCT segmentation to MICRON Software Suite.

Contrary to the traditional understanding that this disorder remains stable, long-term structural changes were observed through spectral-domain optical coherence tomography (SD-OCT) imaging.

Electrophysiologic testing combined with structural imaging to zero in on issues.

Structural and vascular changes detected in RVO-affected eyes and unaffected fellow eyes

Chao Zhou, PhD, a professor of biomedical engineering in the McKelvey School of Engineering at the university, and team received the award from the Advanced Research Projects Agency for Health (ARPA-H).

To speed care, Mount Sinai’s Department of Ophthalmology launched an Eye Stroke Service and developed a treatment protocol for patients.

Elodie Bousquet, MD, PhD, and international researchers studied type 3 macular neovascularization (T3 MNV) using optical coherence tomography. In 64.5% of 31 eyes with T3 MNV, it developed over soft drusen, showing drusen growth and outer layer thinning before T3 MNV.

Studies aim to develop a clinically useful biomarker of retinal capillary changes to monitor the development of a prevalent form of systemic vascular disease and cerebrovascular disease.

The kidney and eye are structurally and functionally similar, and the diseases of the organs may present similarly and via common pathways.

The system hopes to use optical coherence tomography (OCT), while at the same time, leverage air and ultrasonic pulses to excite the mechanical waves in the cornea, enabling the detection of normotensive glaucoma.

The company has come into agreement with IQVIA Services Japan G.K. as well as AUROLAB.

Technology is an option for evaluating, documenting certain types of retinal pathology.
