A Danish study has revealed that 11 and 12-year-olds whose mothers smoked during pregnancy have a 5% deficit in retinal nerve fibre layer (RNFL) thickness compared to the children of non-smoking mothers.
Objective: To determine the relationship between mean axial length and mean peripapillary retinal nerve fibre layer (RNFL) thickness using spectral domain optical coherence tomography (SD OCT) in healthy subjects.
This damages the myelin and disrupts messages travelling along nerve fibres - they can slow down, become distorted, pass from one nerve fibre to another, or not get through at all.
The research debunks the theory that the nervous system should have mainly very short nerve fibre connections between nerve cells, or neurons, to function.
If successful, it will open the door to treating conditions including spinal injuries, the most severe strokes and blindness and deafness caused by nerve fibre injury
This triad of U/L high myopia, peripapillary myelinated nerve fibre and amblyopia has been presented for its rarity.
The loss of myelin in the brain prevents nerve fibres from sending signals properly and will eventually lead to the loss of the nerve fibre itself.
The study found long nerve fibre connections are just as vital as short ones, rebuffing the theory the nervous system should have mainly very short nerve fibre connections between nerve cells to function.
Nerve fibre damage is typically assessed through invasive tests, including nerve and tissue biopsies.
