Aortic regurgitation

Aortic regurgitation occurs when the aortic valve (linking the left ventricle to the aorta) does not close properly when the heart contracts. This means blood leaks back into the left ventricle, which then has to work harder to pump the extra blood away from the heart to the rest of the body. This can lead to the enlargement and thickening of the ventricle wall.

Myelomeningocele

Myelomeningocele is a type of spina bifida. This is when the neural tube has failed to close and the neural tissue is exposed on the baby’s back. The myelomeningocele will look like a sac sticking out from a baby’s back. 

Optic neuritis

Optic neuritis (ON) is an attack of inflammation (swelling) of the optic nerve. The optic nerve is important in sending information from the eye to the brain about what we are seeing. ON is caused by the body’s immune system becoming mis-programmed and activating immune cells to attack the healthy myelin covering the optic nerve.
