OCT

A machine learning approach based on eye scans was employed by researchers to diagnose multiple sclerosis (MS) in children with up to 80% accuracy. Optical coherence tomography (OCT) scans also provided enough data to diagnose other demyelinating diseases with 75% accuracy. OCT is an imaging tool that uses…

After a relapse involving optic neuritis, or inflammation in the nerves connecting the eyes and brain, measurements of retinal thinning may predict the likelihood of full recovery from future relapses in people with multiple sclerosis (MS), a study suggests. The measurement could identify subclinical nerve cell damage that remains…

Physician-researchers at Cedars-Sinai Medical Center, in California, are developing brain and eye imaging techniques to improve the diagnosis and management of multiple sclerosis (MS). MS is characterized by the progressive loss of myelin, the fatty protective sheath around nerve fibers, in the brain and spinal cord due to abnormal…

An imaging technique called optical coherence tomography (OCT) could be useful for monitoring nervous system damage in people with multiple sclerosis (MS), especially early on in the disease, a study in patients reports. The study, “Optical coherence tomography in multiple sclerosis: A 3-year prospective multicenter study,”…

Measurements of the thickness of the eye’s retina — the layer of nerve cells lining the back of the eye — could be used to predict disability progression and relapses in people with multiple sclerosis (MS), a real-world study from Austria suggests. “Our study shows that both crossectional and…

A non-invasive retina imaging technique known as optical coherence tomography (OCT) provided evidence of the neuroprotective effect of ibudilast (MN-166) — an oral medication designed to reduce the body’s inflammatory responses —  in people with progressive forms of multiple sclerosis (MS). The data also…

Compared to low-efficacy disease-modifying therapies (DMTs), high-efficacy medications are more effective at slowing the loss of nerve cells making up different layers of the retina — the region at the back of the eye that enables one to see — in patients with relapsing-remitting…

Inflammation drives the loss of brain volume and thinning of the eye’s retina in the first five years of a multiple sclerosis (MS) diagnosis, an imaging study demonstrates.  The findings support a therapeutic strategy of halting inflammatory activity during this initial period. …

The thickness of two layers of nerve cells forming the back of the eye, or retina, can be used to distinguish patients with progressing forms of multiple sclerosis (MS) from those with stable disease, a study suggests. The study, “Macular ganglion cell–inner plexiform layer…

People with progressive forms of multiple sclerosis (MS) have faster and disease-modifying therapy (DMT)-resistant retinal atrophy (thinning), compared to those with relapsing-remitting MS (RRMS), a study shows. Data also highlighted that the thickness of deeper layers of the retina could be used as potential biomarkers of neurodegeneration in…

Mutations in genes related to the immune system’s first line of defense are associated with a greater likelihood of more severe forms of multiple sclerosis (MS) linked to faster vision loss, a team led by Johns Hopkins Medicine researchers report. Combining high-resolution eye scans and genetic tests,…

Treating relapsing multiple sclerosis (MS) patients with Ocrevus (ocrelizumab) is not associated with retinal thinning — unlike treatment with Rebif (interferon beta-1a), according to two Phase 3 trials. The findings also showed a link between retinal thinning and brain volume loss. The study, “…

Imaging techniques that measure damage to the brain, in addition to those that detect lesions, may be useful in predicting likely disease progression in people with clinically isolated syndrome (CIS), a study found. The study, “Early imaging predictors of longer term multiple sclerosis risk and severity…

Structural changes of the eye retina are a common feature among multiple sclerosis patients with a clinical history of optic neuritis, a Danish study finds. Loss of the myelin protective layer of optic nerve cells due to inflammation causes optic neuritis. About 20 percent of MS have it, and optic neuritis is a symptom of disease progression in about 40 percent of patients. In most cases, symptoms persist, leading to visual impairment or blindness, along with pain. Non-invasive optical coherence tomography can help evaluate neurodegeneration of optic nerve cells. This imaging technique allows a three-dimensional evaluation of internal eye structures, including the thickness of the retina nerve fiber layer. Previous studies have shown that MS patients may present progressive RNFL loss, but this can also be caused by optic neuritis. The use of OCT has been proposed to distinguish MS subtypes and evaluate disease activity. However, little clinical data is available to validate OCT's accuracy and potential as a diagnostic tool. To find out more, a Danish research team conducted a long-term evaluation of structural and functional visual outcomes in MS patients with and without a history of optic neuritis. Researchers observed that patients with a history of optic neuritis had significantly more RNFL thickness loss than those without optic neuritis. They linked reduced RNFL thickness with a 1.56 times higher risk of optic neuritis development. Nevertheless, the team did not find any association between optic neuritis and functional impairment of visual acuity or color vision. Use of high-resolution OCT devices coupled with up-do-date analysis software can improve the diagnostic efficacy of this imaging technique in MS patients, said researchers, who urged more studies to address the relevance of structural changes in MS.

Two presentations at the European Committee for Treatment and Research in Multiple Sclerosis (ECTRIMS) 2016 Congress, now underway in London, underscored the value of measures of neurodegeneration in the eye in predicting a patient’s future disability. Peter Calabresi with the Johns Hopkins School of Medicine opened the session with the presentation, “Tools for…

Genes that encode what are called “complement” immune factors are linked to the breakdown of the retina in multiple sclerosis (MS) patients — a measure that, in turn, predicts brain damage and loss of eyesight. The study, a joint effort between researchers from Johns Hopkins School of Medicine,…

Researchers at Johns Hopkins University in Baltimore found that visual function in multiple sclerosis (MS) patients correlates with cognitive function ands suggests that disease severity and outcomes of neuroprotective therapies in MS patients may be assessed through visual function measurements. The findings were recently presented in the oral presentation “…
