Anisocoria is a condition in which the two pupils of the eye are different sizes; in other words one pupil is larger than the other. In some cases, the abnormal pupil may be the one that is smaller and in other cases the abnormal pupil may be the one that is larger.

The variety of reasons for such occurrences are beyond the scope of a Quora answer. Both pupils fully dilated and non reactive to light indicates death.
