Follow-Up Intervals and Imaging Plans Follow-up for a choroidal naevus should be risk-based, not one-size-fits-all. A small, flat lesion with no symptoms and no high-risk imaging features is often monitored less frequently after stability is confirmed. ¹ In contrast, naevi with one or more risk factors (for example thickness approaching/over 2 mm, subretinal fluid, orange pigment, suspicious ultrasound features, or documented change) are typically reviewed more frequently and may need ocular oncology input. ² What makes follow-up meaningful is repeatable imaging: - Colour fundus photography to compare size/shape over time - Optical coherence tomography (OCT) to detect subtle subretinal fluid and retinal disruption ³ - Ultrasound when thickness/internal reflectivity needs objective measurement This is why monitoring should produce a clear written plan: baseline measurements, which tests will be repeated, the recall interval, and what change triggers escalation. Patients should not be left with "come back if worried" as the only strategy. ¹ ² **References** 1. Chien JL, Sioufi K, Surakiatchanukul T, Shields JA, Shields CL.
