What is the meaning/usage of 瞶?


I am reading a movie scenario magazine and came across the kanji 瞶 that I
cannot understand.

The scenes involved are basically relationship moments between the two main
characters.

Two examples with some context:

WWWJDIC does not match this kanji, though in Edict (via JWPce or Rikaichan) it
says:  
キ see everything

Checking various other references were a dead end.

I realize this is probably non-standard literary usage, but please help me
understand why it may have been used and any deeper meaning.  
Are there better examples of the usage of this kanji?

「瞶る＝みつめる」です。

また、「凝っと＝じっと」だと思われますが、こちらも普通の辞書には見当たりません。

私は61歳の普通の日本人ですが、この二つの漢字は初めて見ました。
