The retina is the light-sensitive film at the back of the eye. A diagnosis of functional diplopia should not be entertained based simply on the absence of gross ocular misalignment, because sometimes very subtle misalignment of the ocular axes, which are difficult to elucidate at the bedside, may require more sensitive tests. They have otherwise normal eyes, and no neurological problems - their eyes just "like to shake." Their vision is usually mildly blurry, and this usually remains stable over time. Macular hole A macular hole is a small gap that opens at the centre of the retina, in an area called the macula. So what about the final category, motor nystagmus? Patients with this type of nystagmus have had the first two types ruled out. Lizards can have both, and so can snakes. For patients in whom neurological nystagmus is suspected, magnetic resonance imaging (MRI) scans of the brain are often ordered, and the child's primary care provider may consult a neurologist for assistance. Turns out it is, but now I cant find any explanation on why some animals have one kind of pupil and others have the other. Children with neurological nystagmus often have other medical issues as well, such as delays in meeting their childhood milestones. There are many different areas within the brain that help control steady, normal eye movements, and problems with each of them can cause different types of nystagmus.
Other people have nystagmus due to a neurological problem. Weed are well-equipped to figure out whether your child's nystagmus is due to an ocular condition. Ocular causes of nystagmus include childhood cataracts, optic nerve developmental problems, and genetic retinal diseases like Leber congenital amaurosis, albinism, retinitis pigmentosa, or achromatopsia, among others. People with nystagmus due to eye problems have abnormal vision, and this decreased visual ability causes the eyes to shake. Nystagmus in children is caused by three different categories of disease: Nystagmus itself is not a diagnosis - it is a sign of another disease. The movements may be very subtle, very prominent, or somewhere in between. These involuntary movements may be horizontal, vertical, or sometimes even rotational. Nystagmus is a medical condition in which the eyes move involuntarily, often shaking back and forth.
