In younger patients, the clinical priority is excellent baseline documentation and a clear monitoring plan, because a longer lifetime horizon makes long-term surveillance more relevant. ²
For iris naevi, age ≤40 years is part of the ABCDEF framework for higher risk of growth into melanoma (in a tertiary ocular oncology cohort). ¹ That does not mean most young patients develop melanoma, it means clinicians should be meticulous about:
- slit-lamp photography (size, margins, configuration)
- checking for hyphema, ectropion uveae, diffuse spread, or angle involvement
- documenting change over time
For choroidal naevi, many lesions discovered in younger adults are benign. The key is to avoid both extremes: dismissal without imaging and over-referral without risk features. Photography and OCT help detect subtle fluid or retinal change, and ultrasound can quantify thickness when needed. ³
At Blue Fin Vision®, young patients are managed with structured imaging, explicit documentation of risk features, and follow-up intervals based on objective findings rather than reassurance alone.
