CCM can determine nerve harm in sufferers with lengthy COVID, new research finds

New analysis, launched by a workforce based mostly in Turkey, Qatar, and the UK, has indicated {that a} specialised eye examination can be utilized to determine lengthy COVID.

Revealed within the British Journal of Ophthalmology, the analysis discovered that corneal confocal microscopy (CCM) – a non-invasive eye check that conducts real-time imaging of corneal nerve fibres – may also probably be used to verify suspected instances of lengthy COVID by figuring out particular nerve harm.

CCM can also be used to determine different situations, similar to diabetic neuropathy, Parkinson’s illness, a number of sclerosis, and dementia.


Penned by researchers from Turkey’s Necmettin Erbakan College, Weill Cornell Medication-Qatar (WCM-Q), and the UK’s College of Manchester, the research said that CCM “identifies corneal small nerve fibre loss and elevated DCs [dendritic cells] in sufferers with lengthy COVID, particularly these with neurological signs.”

In consequence, “CCM could possibly be used to objectively determine sufferers with lengthy COVID.”

The paper added: “Lengthy COVID is characterised by a variety of doubtless debilitating signs which develop in at the least 10% of people that have recovered from acute SARS-CoV-2 an infection.”

Signs of lengthy COVID embrace headache, tingling and/or numbness, neuropathic ache, a loss or change within the senses of style and scent, and so referred to as “mind fog”.


In accordance to a press release by WCM-Q, “nerve harm noticed within the corneas utilizing CCM might be reliably used as an indicator of nerve harm in different components of the physique.

“CCM’s worth as a diagnostic instrument is elevated by a variety of essential elements: the check takes just a few minutes, is totally non-invasive, causes nearly no discomfort for sufferers, utilises current and broadly out there ophthalmic tools, and might be achieved within the clinic.”


“The predominance of neurologic signs in individuals with lengthy COVID prompted us to analyze whether or not CCM could possibly be used to objectively determine nerve harm in sufferers with the illness,” mentioned Rayaz Malik, professor of drugs and assistant dean for medical investigations at WCM-Q. “We’re the primary group on the earth to report a really sturdy affiliation between nerve harm noticed utilizing CCM and lengthy COVID. 

“Though the vast majority of individuals had gentle COVID, sufferers with extra extreme illness had proof of larger corneal nerve harm, suggesting that the severity of nerve harm could also be associated to the severity of illness at presentation.

“We imagine CCM has the potential to function a particularly precious instrument for use by physicians to assist diagnose and assess the evolution of lengthy COVID and to find out the severity in particular person instances. The identification of underlying nerve harm additionally permits us to consider this situation as a neurodegenerative illness, which can be amenable to remedy.”
