Rare Eye Cancer Diagnosis Highlights Importance of Routine Exams

A routine eye exam can be life-saving, as demonstrated by the experience of Elaine O’Callaghan, a woman from Cork, Ireland, who received a diagnosis of ocular melanoma, a rare form of eye cancer, in 2018. Her case underscores the critical role of regular eye check-ups and the potential for early detection.

The Unexpected Diagnosis

O’Callaghan’s journey began with a scheduled eye examination at Specsavers in Portlaoise as part of her two-year check-up. During the exam, she mentioned a “flicking” sensation in her right eye to the optician. This prompted the optician to recommend an Optical Coherence Tomography (OCT) scan, which was performed immediately. The scan results led to a recommendation for an urgent appointment at either a hospital in Dublin or the Whitfield Clinic in Waterford.¹

After seeking a second opinion at the Whitfield Clinic, further scans revealed a detached retina. An MRI was then ordered to determine the cause. O’Callaghan was quickly connected with Mr. Noel Horgan, an ocular cancer specialist at the Royal Eye and Ear Hospital in Dublin, as he is the only doctor in Ireland specializing in this type of cancer.¹

Understanding Ocular Melanoma

Ocular melanoma is a rare cancer affecting approximately five in 10,000 people in Europe.¹ However, Ireland and other countries in Northern Europe have a higher incidence of the disease. While the exact cause is unknown, it appears to be more common in individuals with blue eyes, fair skin, and a tendency not to tan.¹

Symptoms can include a shadow in the field of vision, flashing lights, reduced vision, or the condition may be discovered incidentally during a routine eye exam.¹

Treatment and Ongoing Monitoring

The most common treatment for ocular melanoma is brachytherapy, a targeted radiation therapy delivered through a minor plate surgically attached to the eye.¹ St. Luke’s Hospital in Dublin is the only facility in Ireland offering this treatment.¹

In O’Callaghan’s case, the brachytherapy was successful in reducing the tumor size, and her eye was preserved. However, she experiences a gradual decline in vision in the affected eye, a potential side effect of the radiation.¹

Due to the risk of ocular melanoma spreading to the liver, O’Callaghan undergoes regular liver scans with an oncologist at St. Vincent’s Hospital in Dublin. Initially, scans were performed every three months, and now, eight years post-treatment, they are conducted annually.³

The Importance of Support and Awareness

O’Callaghan acknowledges the anxiety associated with ongoing monitoring and the “survivor’s guilt” she feels after learning that two other women from her support group at St. Luke’s Hospital have passed away.¹

To cope and offer back, she established a cancer support group at her workplace, Pfizer, to provide a space for employees and their families affected by cancer to share experiences and offer support.³ She also actively participates in Daffodil Day events, inviting representatives from the Irish Cancer Society to speak to employees.¹

Key Takeaways

• Routine eye exams are crucial for early detection of eye cancer.
• An OCT scan can be a life-saving diagnostic tool.
• Ocular melanoma, while rare, has a higher incidence in Northern Europe.
• Early diagnosis and treatment, such as brachytherapy, can be highly effective.
• Ongoing monitoring is essential to detect potential spread of the cancer.
• Support groups can provide valuable emotional support for patients and their families.

Elaine O’Callaghan’s story serves as a powerful reminder of the importance of proactive healthcare and the potential for positive outcomes with early detection and treatment of even rare cancers.
