History
Brinzolamide/brimonidine was approved for medical use in the United States in April 2013, and in the European Union in July 2014. References

The patients history might also exhibit kidney problems, such as proximal nephron dysfunction. There may also be endocrine conditions, such as diabetes or hypoparathyroidism. The patient might have also had a gastrointestinal condition which could have been due to liver disease, as well as episodes of nausea or vomiting. Multiple lipomas in the skin, sideroblastic anemia and pancytopenia in the metabolic system, or short stature might all be examples of patients with possible symptoms of MERRF disease. Treatment
Like many mitochondrial diseases, there is no cure for MERRF, no matter the means for diagnosis of the disease. The treatment is primarily symptomatic. High doses of coenzyme Q10, B complex vitamins, and L-Carnitine are used for the altered metabolic processing that results in the disease. There is very little success with these treatments as therapies in hopes of improving mitochondrial function. The treatment only alleviates symptoms, and these do not prevent the disease from progressing. Patients with concomitant disease, such as diabetes, deafness, or cardiac disease, are treated in combination to manage symptoms. Research
The Journal of Child Neurology published a paper that discusses possible new methods to test for MERRF and other mitochondrial diseases through a simple swabbing technique. This is a less invasive technique which allows for an analysis of buccal mitochondrial DNA, and showed significant amounts of the common 5 kb and 7.4 kb mitochondrial DNA deletions, which are also detectable in blood.
