Sydney teen diagnosed with stage four uveal melanoma after blurred vision at 14

A Sydney mechanic has been diagnosed with stage four metastatic uveal melanoma after first noticing blurred vision in one eye aged 14, and is now receiving experimental treatment after the cancer spread to his liver.

Jack Clement, 19, first experienced sudden blurring in his right eye while at school. He was later diagnosed with ocular melanoma, which doctors found had caused a retinal detachment. Radiation, injections and laser treatments followed, but this June scans showed the cancer had metastasised to his liver and he was given a prognosis that, without treatment, would likely be about 12 months and with treatment perhaps up to two years, he said in an interview.

Clement said the news left him stunned. "I was just… numb," he told the Daily Mail. "What else can you do? You've got to keep going." He is now on an experimental therapy that doctors have put in place indefinitely; the treatment leaves him exhausted and unable to work full time.

Family has been central to his care. Clement's partner, Ariana, who has been with him since school, gave up her job as a preschool teacher to move in with him, his mother and his eight-year-old sister, Amelia. Clement said his partner helps with daily needs and that the family have shielded the younger child from the full details of the diagnosis. "Ariana's very helpful, always looking after me, making sure I'm keeping my fluids up, eating right, sticking to my diet," he said. "My friends and my family have been more than I could ever ask for, support-wise. Everyone's staying strong for me. I've just got to keep going."

Clement has adopted a strict diet and continues light activity, such as short walks and visits to colleagues. His family has launched a GoFundMe to help cover medical, travel and living costs as they adjust to the financial impact of treatment and reduced work.

Uveal melanoma, sometimes called ocular melanoma, is the most common primary eye cancer in adults but remains rare. It develops in the uvea, the middle layer of the eye that produces pigment, and differs from skin melanoma. Because tumors form inside the eye and often produce no symptoms until they affect vision, many cases are detected during routine eye exams rather than through patient complaints.

When uveal melanoma metastasises, the liver is the most frequent site, occurring in as many as 95 percent of cases where the cancer spreads. Doctors explain that cancer cells can travel through the bloodstream and are trapped in the liver, which filters blood, making the disease significantly harder to treat once it has spread.

Early symptoms of uveal melanoma can be subtle and are sometimes dismissed, particularly in younger people. Common signs include sudden or persistent blurring in one eye, loss of peripheral vision, small floaters or flashes of light, dark patches on the white of the eye and changes in pupil shape. Medical experts recommend regular eye checks because optometrists can identify abnormalities long before symptoms become severe.

Though uveal melanoma is more frequently diagnosed in older adults, clinicians say Clement's case underscores that it can occur at any age. Physicians cited in accounts of the case noted potential contributing factors, including individual eye pigmentation and prolonged ultraviolet exposure. They advise people not to ignore vision changes and to seek prompt assessment if they experience persistent blurring, flashes or other visual disturbances.

Clement and his family have sought to balance ongoing care with preserving daily life. He said he tries to remain active despite treatment-related fatigue: "I don't really want to be rotting in bed. You just gotta keep active in this sort of situation." The family has limited discussion of the diagnosis with the youngest member to protect her from the emotional burden while they focus on treatment and support.

Health authorities recommend routine eye examinations every two years for most people, and more frequently for those with a family history of melanoma or significant sun exposure. Early detection, clinicians say, can make a critical difference between treatment options confined to the eye and disease that has spread to other organs.
