Nystagmus is not usually a stand-alone disease and can be combined with ophthalmic or systemic pathologies. There are two main categories.
I. From the ophthalmological point of view, there are the following categories.
1. albinism, the
2. congenital cataracts.
3. Optic nerve dysplasia.
4. macular degeneration.
5, retinitis pigmentosa, Wang Yuan, Beijing Children’s Hospital Ophthalmology Department
6, congenital glaucoma
7, corneal leukoplakia and other diseases that seriously affect vision can cause nystagmus.
8.Nystagmus of unknown etiology
Second, special types of nystagmus.
1.Vertical nystagmus.
2.Upward jumping nystagmus.
3.Downward-jumping nystagmus.
4. Seesaw-like nystagmus.
5. Periodic nystagmus
The above nystagmus is caused by central lesions in the brain, such as occupational lesions, inflammation, hemorrhage, etc. These diseases must be seen in the neurology department of a specialized hospital to avoid delays and treatment.
Why are albino children afraid of light?
Usually we see many children with albinism are afraid of sunlight, why is this? This foreign nystagmus experts study many, albino fundus is a group of monogenic recessive genetic disease related to melanin biosynthesis, manifested as eye, skin, hair melanin deficiency. In addition to ocular pigment deficiency and associated ocular symptoms, patients with oculocutaneous albinism have significant pigment deficiency in both skin and hair, such as fair skin and white, blond or brown hair. The lack of melanin can cause a range of abnormal ocular manifestations, with children having light or absent iris and retina color, significant photophobia, iris translucency, lack of fundus coloration, nystagmus, high refractive error, low vision, poor stereo vision, and other clinical manifestations. The iris of albinos is usually blue or gray, and in some children with iris pigment deficiency, the iris can appear purple when exposed to direct light. The translucency of the iris not only makes light entering the eye scattered, causing difficulty in focusing, but also allows a large amount of light to enter the eye, causing the patient to be particularly sensitive to light, known as “photophobia”.
For these children, we can fit them with contact lenses that are transparent in the middle and opaque on the periphery, just like the “pupil” glasses that some of our young girls wear today. These contact lenses are like the “contacts” that some of our young girls wear today.
