Camera flashes saved an infant's life by detecting a rare form of eye cancer that appeared in snapshots of the Arizona baby. The tot's mother noticed last December that the camera's flash caused a white "glow" in the left eye of 4-month-old Ryder Temarantz.

Baby Ryder's mother is 36-year-old Andrea Temarantz. She told ABC News she thought there was a problem with the camera phone.

However, Temarantz then used a new Nikon D3300 DSLR camera she had been given as a Christmas gift. After the white glow showed up again in photos she took Ryder to get a checkup at his doctor's office.

Baby Ryder was diagnosed on January 5 with retinoblastoma cancer in his left eye. A white cancerous tumor in the back of the infant's eye was causing the glow when light from the camera flashes reflected off it, according to ABC News.

Temarantz and her husband then decided to take their baby to Memorial Sloan Kettering Cancer Center in New York City. It is has the world's largest team of retinoblastoma-treating doctors.

Dr. David H. Abramson is chief of Ophthalmic Oncology Service at Memorial Sloan Kettering. He explained that the tumor in Ryder's eye had not spread to other important organs, such as the brain.  Ryder will have 3 to 6 rounds of chemosurgery.  

The New York physician explained that a very thin catheter is threaded through the body's stomach, chest, and neck. It sends a small dose of chemotherapy into the cancer tumor.  

The medical procedure is the best option for young patients because regular chemotherapy has many strong side effects. It also could have increased the risk of the cancer spreading, according to New York Daily News.  

Ryder's NYC doctor explained that his chance of recovering from the eye cancer is 99 percent. He will also still have some vision in his left eye.

Abramson noted that it was important that Ryder's mom noticed the white glow in the photos. Last year half of all children worldwide with retinoblastoma died.

Temarantz informed ABC News that Ryder is still active and alert. She is thankful for Abramson and his medical team.
