Skeletal muscle stained for both cytochrome oxidase (COX) and succinic dehydrogenase (SDH), two mitochondrial respiratory chain enzymes. Fibers that stain only for SDH and are COX-negative appear blue. Original magnification X 50.
Bilateral ptosis and external ophthalmoplegia. Top: patient looking straight ahead. Below: patient is being asked to look in the direction of the arrow in each case. Restriction of eye movements in each direction is demonstrated.
Modified Gomori Trichrome stain showing ragged red fibres. These show red staining round the periphery as well as within the sarcoplasm, giving a speckled appearance. Of the two affected muscle fibres pictured here, the one on the right shows a more extreme degree of mitochondrial proliferation and also some degeneration/vacuolation than the one on the left.
