BOW -- Delaney Spain-Kelly was diagnosed at 18 months with an inoperable brain tumor in her hypothalamus.

Despite multiple rounds of chemotherapy aimed at controlling the tumor's growth, the malignancy began to press against Delaney's optic cavity, leading to severe vision loss.

She has light perception in her right eye and a quarter of her field of vision in her left.

Delaney is 9 years old. Doctors have predicted she will lose her sight completely by the time she reaches adulthood.
