Is ophthalmoplegia a genetic disorder?

When the nuclear genes POLG, TWNK, RRM2B, or SLC25A4 are involved, progressive external ophthalmoplegia is usually inherited in an autosomal dominant pattern , which means one copy of the altered gene in each cell is sufficient to cause the disorder.

What causes external ophthalmoplegia?

CPEO can be caused by genetic changes in any of several genes, which may be located in mitochondrial DNA or nuclear DNA. It has different inheritance patterns depending on the gene involved in the affected individual.

What is CPEO disease?

Chronic progressive external ophthalmoplegia (CPEO), also known as progressive external ophthalmoplegia (PEO), is a disorder characterized by slowly progressive paralysis of the extraocular muscles.

Can ophthalmoplegia be cured?

The term “supranuclear” refers to the part of the brain that is affected, an area above the nuclei. Supranuclear ophthalmoplegia also may be called progressive supranuclear ophthalmoplegia to reflect the fact that the condition is progressive — that means the condition gets worse over time and there is no cure.

Who treats ophthalmoplegia?

Ophthalmoplegia is most often a symptom of another syndrome or disease. But regular trips to the eye doctor may aid in early detection. Even if you have normal vision, it’s recommended that you visit an eye specialist about every two years.

Is ophthalmoplegia curable?

Does ophthalmoplegia go away?

Treatment of ophthalmoplegia is directed at correcting any underlying disorders, if possible. In many cases, isolated nerve palsies resolve on their own over time, and treatment consists of patching the affected eye to alleviate any transient double vision.

How do you fix ophthalmoplegia?

Is CPEO a muscular dystrophy?

Important differential diagnoses of CPEO are oculopharyngeal muscular dystrophy (OPMD) and ocular myasthenia. OPMD typically manifests after age 40 years, whereas CPEO typically starts before that age.

How is CPEO treated?

There is no cure for CPEO, but treatment can control your symptoms. Special glasses with fine metal bars (ptosis props) can help to lift up drooping eyelids. If these are unacceptable, and the ptosis is severe, surgery may be done to lift the eyelids. Some patients find that hearing aids may improve hearing.
