Australia has the world's highest rates of skin cancer,a direct consequence of high UV exposure and pale skin in a population that evolved in lower-UV latitudes. Less widely known is that UV radiation also causes cancers of the eye and surrounding structures. For outdoor workers who accumulate decades of UV exposure without eye protection, the risk is meaningful and worth understanding.
Types of UV-Related Eye Cancer
Conjunctival Carcinoma
Squamous cell carcinoma of the conjunctiva is the most common form of eye surface cancer. It typically appears as an elevated, slightly opaque, or vascularised growth on the conjunctiva or limbus (the junction between cornea and conjunctiva). It is strongly associated with UV exposure and is more common in men with outdoor occupational histories. It is locally invasive and can spread to adjacent structures if untreated.
Ocular Melanoma (Uveal Melanoma)
The most common primary eye cancer in adults. Unlike skin melanoma, it arises from the uveal tract,the choroid, ciliary body, or iris,rather than the eye surface. The relationship with UV is less direct than conjunctival carcinoma, but UV exposure is considered a contributing risk factor. Ocular melanoma may cause no symptoms in its early stages, which is why routine retinal examination matters.
Eyelid Skin Cancers
Basal cell carcinoma (BCC) and squamous cell carcinoma (SCC) commonly occur on the eyelids and periorbital skin,areas that receive high cumulative UV exposure and are often missed during skin cancer checks. Outdoor workers should specifically ask their GP or dermatologist to examine eyelid skin.
Warning Signs
- A new, elevated or fleshy growth on the white of the eye or eyelid margin
- A dark spot or pigmented area on the iris or white of the eye that appears to be growing
- Unexplained vision disturbance,floaters, flashes, or reduced peripheral vision
- A non-healing lesion on the eyelid
How We Monitor
Dr Tahiri performs detailed anterior segment and posterior segment examination at every comprehensive eye test. OCT imaging allows detailed retinal examination to detect uveal melanoma changes. Any suspicious conjunctival or eyelid lesion is photographed, monitored, and referred appropriately. Annual eye testing is especially important for long-term outdoor workers over 40.
