Sorry to hear about your daughter. It is hard to know the cause without all the test results at the current time, especially the MRI, as this seems to be something less common. If she looks well in other aspects (except for the vision loss), and has already been evaluated by a pediatrician, ophthalmologist, and a pediatric neurologist, you are doing everything you can, and it seems that everything necessary is being done. Vision requires normal eyes, normal optic nerves connecting the eyes to the brain, and normal function of the visual cortex of the brain, and of course normal response to vision requires good function of the rest of the brain. Generally most problems affecting the eyes affect only one eye at a time, and can be seen by the ophthalmologist (either anterior chamber problems such as cataracts or posterior chamber issues such as retinoblastoma). Problems affecting the optic nerves (e.g optic neuritis) are more often seen in older kids (e.g with multiple sclerosis) and are very rare at 15 months. Rarely, there can be problems near where the optic nerves come together just behind the eyes (optic chiasma) when masses (eg. craniopharyngioma)/cysts push on them and can cause visual loss. It is also rare for things to affect the visual cortex of the brain. I suspect that the MRI will be of help. If it does find something, it might need other specialists (e.g. neurosurgeon) to provide further information on management.
1 year old sudden loss of visionOn Thursday, my 15 month olds babysitter noticed that she wasnt making eye contact like normal. At home, I noticed the same thing. Normally, if I look at her and smile she smiles back. But it looked like she was looking right past me. Along with that, she was not tracking objects with her eyes.I took her to the pediatrician on Friday who was concerned and wanted her to see an ophthalmologist right away. So we did that, she had a full eye exam with her eyes dilated and there was nothing wrong (like far sightedness or strabismus etc) with her eyes. The ophthalmologist was concerned too and called a neurologist who wanted us to go to the ER so we could be admitted into neurology over the weekend.The ER did a lot of blood work, a spinal tap for fluid (I cant remember the name- Im sorry.) and the doctors there just generally said they were stumped.We are on day 2 of being in the pediatric neurology unit. Shes having an EEG done for 24 hours and hopefully an MRI today. The neurologist says hes fairly confident she isnt having seizures but wants to cover everything.I hope one or both of those things gives us an answer but in the mean time all I have to do is think. What could possibly have caused this loss of vision seemingly overnight? She responds to sounds but not objects. Shes had hundreds of lights (from nurses doctors etc) flashed right in her eyes and she does nothing like youd expect. They shined a light in my eyes to show me how abnormal it was that she did nothing because I instinctively moved my eyes.Also... no falls, no high fevers, no recent illness, her birth was normal, shes developmentally normal.Does anyone have any idea of what this could be?
