Oli is just a little quirky

Sometimes you need to look at Life from a different perspective.

As the first few days of Oli’s life turned into the first few weeks, results began to trickle in from Oliana’s many tests.  And I do mean trickle. Sometimes it seemed to take forever to hear anything back.  I guess I can sum up what most of those tests found by saying, they were pretty normal, except… not completely.

 My sweet Oli is just kind of quirky.

The cardiologist said that her echo was normal except for a few things.  Oli’s first quirk.  The right ventricle in her heart was a little larger than normal and there was a small hole in her heart that should have closed when she was born, except that it didn’t.  It was very minor.

She had a repeat pelvic ultrasound to check her kidneys.  They still had extra fluid in them and then the doctor threw in a bonus quirk.  She had 2 uterus's. 

What?  I’d never heard of that either. 
I was starting to think that I should have paid more attention in nursing school.

Of course, as soon as I got home I Googled “two uteruses”.  

Have I mentioned how much I love Google?

Apparently this is not all that uncommon. 
Google told me that the there were two draw backs.
Sometimes when a woman with two uterus's gets pregnant the baby can be born preterm because the uterus's do not stretch to the size of one normal uterus.  The baby runs out of room.

The second draw back was that it is possible for a woman to get pregnant at two different times and have pseudo twins.  A baby in each uterus.

Well, Google.  I’d say those are pretty big drawbacks!!!

A trip to the endocrinologist revealed that her pituitary labs were normal, except her pituitary gland did not look normal on the MRI.  He said that her posterior pituitary gland was ectopic.  Which just means that it wasn’t in the spot that it was supposed to be.  Oli has had a few more MRI’s since then and I have heard many different opinions about how her pituitary looks. 

Is it moving? Changing? Mutating?  I have no idea. 

I don’t think anyone really has a definitive answer as to what is wrong with the appearance of that gland. 

I told you she was quirky.

The rest of the MRI results were normal except….(Yep. You guessed it) for a few things.

Apparently she did not have an optic chiasm or a pineal gland.

Are those important? 

Here is what Google tells me about these VERY important pieces of her body.

The optic chiasm or optic chiasma (Greek χίασμα, "crossing", from the Greek χιάζω 'to mark with an X', after the Greek letter 'Χ', chi) is the part of the brain where the optic nerves (CN II) partially cross. The optic chiasm is located at the bottom of the brain immediately below the hypothalamus.[1]


[edit] Pathways

The images on the nasal sides of each retina cross over to the opposite side of the brain via the optic nerve at the optic chiasm. The temporal images, on the other hand, stay on the same side. This allows the images from either side of the field from both eyes to be transmitted to the appropriate side of the brain, combining the sides together. This allows for parts of both eyes that attend to the right visual field to be processed in the left visual system in the brain, and vice versa. This is linked to skin sensation which also reaches the opposite side of the body, after reaching the diencephalon (rear forebrain). This decussation (crossing) is an adaptive feature of frontally oriented eyes and therefore having binocular vision. (Some animals, with laterally positioned eyes, have little binocular vision, so there is a more complete crossover of visual signals.)
Beyond the optic chiasm, with crossed and uncrossed fibers, the optic nerves become optic tracts. The signals are passed on to the lateral geniculate body, in turn giving them to the occipital cortex (the outer matter of the rear brain).[2]

The pineal gland (also called the pineal body, epiphysis cerebri, epiphysis, conarium or the "third eye") is a small endocrine gland in the vertebrate brain. It produces the serotonin derivative melatonin, a hormone that affects the modulation of wake/sleep patterns and seasonal functions.[1][2] Its shape resembles a tiny pine cone (hence its name), and it is located near the centre of the brain, between the two hemispheres, tucked in a groove where the two rounded thalamic bodies join.

The MRI also showed that her optic nerves are so extremely small that they can hardly be visualized.  In a few years, they weren’t visualized at all.

And that folks is one reason why my girl does not see and a BIG reason why she does not sleep!
