A very small number of naevi that show growth or other suspicious features would need treatment. Fundus photographs (photographs of the retina) are helpful in monitoring changes, although not all naevi require regular eye clinic monitoring. The presence of these specific features would require a further referral to a regional centre (Sheffield) for further assessment.

There are specific rare features of naevi which can be a warning sign of the possible development of early Choroidal Malignant Melanoma. Generally, typical naevi are left well alone, but suspicious lesions are monitored as a very small percentage of naevi can develop into a malignant (cancerous) lesion known as Choroidal Malignant Melanoma (CMM). Naevi tend to be incidental findings when you have an eye examination at the opticians or ophthalmic Department for other eye problems. Just like in the skin, the eyes contain cells which produce pigment and these cells can cause these “moles” to develop inside the eye and are present in about 5 in 100 of the general population, most commonly in people with dark features.
COLORDIAL NEVUS SKIN
They are similar to skin naevi (moles) that are present in other parts of the body and are probably present at birth, growing mainly in childhood and rarely beyond puberty. They are pigmented (darkly coloured) patches seen in the retina at the back of the eye. If after reading it you have any concerns or require further explanation, please discuss this with a member of the healthcare team. It is not intended to replace the discussion between you and the healthcare team, but may act as a starting point for discussion. Most of your questions should have been answered by this leaflet.
