Overview. Coenzyme Q10 (CoQ10) is a substance that helps convert food into energy. CoQ10 is found in almost every cell in the body, and it is a powerful antioxidant. Antioxidants fight damaging particles in the body known as free radicals, which damage cell membranes, tamper with DNA, and even cause cell death.
Chapter 4 - Extraocular movement. Eye movements are controlled by muscles innervated by cranial nerves III, IV and VI. In this chapter, the testing of these cranial nerves will be discussed. The most common symptom of damage to these nerves is double vision.
Pressure on parts of the brain or cranial nerves (which connect the brain directly to various parts of the head, neck, and trunk) can affect eye movements. People may have double vision or be unable to move their eyes in certain directions, or the eyes may move involuntarily in certain ways (called nystagmus).
