How my boy’s eye ‘wobbling’ ended up being a BRAIN TUMOUR: Mother shares shock symptom that left her 11-year-old visually impaired

When Zac Eckworth’s eye started to “wiggle,” his parents never expected doctors to blame a brain tumor.

Yet that is exactly what happened when he was only 14 months old.

More than a decade later, karate-loving Zac, now 11, is still battling the slow-growing masses.

Zac, visually impaired from his optic nerve glioma, is currently enrolled in a trial of a “life-changing” drug, which he has been taking since he was five.

His mother Miriam, from Basingstoke, praises the drug for ‘giving him the chance to lead a relatively normal life’.

Zac Eckworth, from Hampshire, has been battling cancer for ten years after his parents noticed his eye was wobbly and rushed him to hospital when he was just 14 months old

Zac “couldn’t be a kid” growing up as he had to undergo grueling chemotherapy while his peers played.

Doctors hope dabrafenib, the drug Zac is taking, can keep his tumor at bay.

They’ll check to see if the mass — located on the nerve that connects the eye to the brain — responds once treatment stops in the next few years.

Discussing her son’s struggles, Miriam, 46, said: “It was hard for Zac, and it was hard for us to see that he couldn’t be a kid.”

But she said he has a good quality of life, which allows him to “recover emotionally from what he’s been through.”

His parents remembered his symptoms and said they noticed his eye “wiggling.”

Miriam and her husband, Colin, took Zac straight to the doctor.

He was referred to an eye clinic, where he was then sent straight to Princess Alexandra Hospital in Harlow for an MRI scan.

After an overnight stay in the hospital, medics then diagnosed Zac with an optic nerve glioma.

The masses make up about 5 percent of all childhood brain tumors, data suggests.

Early symptoms affect vision given the tumor’s location in the brain. Children with the tumor may have squinting, double vision, blind spots, or a tilted head. Others may get “flickering eyes,” like Zac.

A week after his diagnosis, Zac was referred to specialists at Great Ormond Street Hospital. There he underwent several rounds of chemotherapy.

Tests showed that it remained stable after the first batch.

But after nine months it continued to grow and Zac had to undergo more chemotherapy.

Zac's parents say his quality of life hasn't diminished despite his battle with cancer and his visual impairment - he has several hobbies and even has a black belt in karate

Miriam, who works as a dog behaviourist, said: ‘This has been a very difficult time for the family.

“Our daughter had also just been born and we knew the difficulties chemotherapy would entail for Zac.

Doctors eventually discovered that Zac’s tumor carried a mutation that made him a candidate for dabrafenib, an experimental drug.

It works by targeting certain proteins made by the genetic idiosyncrasy that promote the growth of masses, effectively preventing it from increasing in size.

Zac responded well to the treatment, which his mother described as “life-changing.”

Miriam said, “It’s given Zac the chance to live a relatively normal life.

“We are grateful for research that allows Zac to do so many things as 11-year-old boys.”

However, his tumor does not stop him.

Nearly black belted in karate, he plays the keyboard, enjoys DJing and playing video games in his spare time. He also enjoys playing target ball – a sport for the visually impaired.

His school supports him a lot, he learns braille and they provide him with large print.

What is an optic nerve glioma? The slow-growing tumor that usually affects children

Optic nerve glioma, also known as optic nerve glioma (OPG), is a slow-growing tumor that usually affects children.

The tumor originates in or around the optic nerve, which connects the eye to the brain and, as it progresses, presses on the optic nerve, causing vision problems.

Three quarters of optic nerve glioma cases are diagnosed in children and teens rather than adults.

Optic nerve gliomas account for 5 percent of all childhood brain tumors.

It’s not known what causes a brain tumor in general, but research has shown that about 50 percent of optic nerve gliomas diagnosed in children and teens are related to a genetic condition called neurofibromatosis 1 (NF1).

A blood test can determine if a patient has NF1. This can be inherited from a parent, but in about 50% of cases the child will be affected first in the family.

What are the symptoms of an optic nerve glioma?

  • Deterioration of vision
  • Reading becomes more difficult
  • squint
  • Flickering eyes
  • Double vision
  • Blind spots
  • Tilt head
  • Eye protruding

If there is increased pressure in the head due to the size of the tumor, the following symptoms may appear:

  • Nausea and vomiting
  • Lethargy and irritability
  • Headache

How is an optic nerve glioma treated and diagnosed?

Optic nerve gliomas are usually diagnosed by CT and MRI scans, ophthalmitis assessment, or endocrine assessments.

Treatment may include chemotherapy with the aim of shrinking and stabilizing the tumor, and radiotherapy which is usually offered to patients after chemotherapy – except those who test positive for NF1, where the risk of secondary tumors after radiotherapy is considered too high.

Surgery is another treatment option, but it’s not always used for optic nerve gliomas because of the risk of damage in sensitive areas.
