Movement
A deficiency in vitamin B-1, also known as thiamine, might cause eye muscle weakness and trembling called a nystagmus. These movements might range from up and down, side to side or circular wobbling, and the person with the deficiency cannot control these motions. In rare instances, a deficiency in vitamin B-12 might also result in eye movement disorders.
