Predictive value of retinal atrophy for cognitive decline across disease duration in multiple sclerosis.

Listen folks, we’ve done a fantastic study here, a really great study. We looked at the connection between changes in retinal thickness and cognition in people with MS. We used this incredible tool, optical coherence tomography (OCT), to measure neuroaxonal damage. We had a big group, 207 people with MS, and we divided them based on how long they’ve had the disease.
We found something amazing, something really big. Changes in retinal thickness over 3.2 years were linked to changes in cognitive scores. This was true for the whole group and especially for those with the disease for more than 5 years. Now, if you’ve had MS for less than 5 years, the changes in cognition were more related to less use of disease-modifying drugs, not OCT metrics.
But here’s the kicker, a retinal nerve fibre layer (pRFNL) of 88 µm or less was linked to earlier cognitive disability and a higher risk of cognitive deterioration. Now, a ganglion cell-inner plexiform layer (GCIPL) of 77 µm or less wasn’t linked to a higher risk of cognitive decline, but we saw a trend at 91.5 µm in people with longer disease.
So, what does this all mean? It means that retinal thinning is connected to cognitive decline. It shows that cognitive dysfunction is a late result of neuroaxonal damage. And measuring the pRFNL? It’s a great way to identify people at risk of cognitive dysfunction. It’s a big deal, folks, a really big deal.
