Chemosurgery goes directly to tumor.

Trying a more focused way to attack a rare eye cancer

For all the technology at Shields' disposal, her most reliable instruments were her own trained eyes. Because of the blood, she couldn't clearly see the tumor, or tell whether it had sloughed clumps of cells into the vitreous, the clear gel that fills the eyeball.

Removing the bloody gel with microsurgery would risk spreading the cancer. Better to proceed with chemosurgery and hope the blood went away naturally over three to five months.

"We see bleeding in about 10 percent of [chemosurgery] patients," Shields said. "In half of them, it resolves."

Story continues below.

The rest, she said, have to be enucleated, just to be safe.

 

Continuing uncertainly

Three months later, on June 1, the three chemosurgeries were done, but the uncertainty continued.

Shields told the Sanzones that, based on ultrasound, the tumor was "a dead scar." However, Tyler had fresh bleeding in the vitreous.

Four months of close follow-up would tell if he could safely keep his right eye.

Still, Shields said, "there is much to be thankful for."

Tyler was now 7 months old, sprouting adorable curls. The only outward sign of his ordeal, a slight eyelid droop, would likely go away. He could perceive light with the eye, although the retina had not reattached. And his left eye remained fine, suggesting his mutation was a fluke, not heritable.

Shields foresaw "a wonderful, full life" for him.

So did his parents.

"We are humbled and have a deep sense of gratitude as Ty has turned a corner in this journey," Emily e-mailed relatives, friends, and doctors that night. "He has taught us at a young age to realize that each day is a gift and to live life to the fullest."
