internal ophthalmoplegia, ophthalmoplegia interna
Paralysis affecting only the sphincter muscle (ringlike band of muscle fibers) of the eye pupil and the ciliary muscle (smooth muscle).
lagophthalmia, lagophthalmos
A morbid condition in which the eye stands wide open, giving a peculiar staring appearance.

A squint, squinting; a condition in which the lines of sight of the two eyes cannot be directed at the same point of fixation under normal conditions; therefore, oblique vision.

It is normal in newborn babies, but it should stop by the time the baby is six moths old. Loxophthalmus beyond the newborn period may be caused by a blow on the head, disease, heredity, or other conditions.
