| Summary: |
Naevi are the most common
melanocytic lesions of the choroid, usually found during
routine ophthalmic examination. Typically, a choroidal
naevus is flat or slightly raised, dark in colour and
circumscribed. Chronic naevi may lead to degeneration of
the retinal pigment epithelium overlying the naevus .
Sometimes secondary retinal changes may appear and
although most naevi are benign all require
differentiation from malignant melanoma, photographic
documentation and regular observation.
Optical coherence tomography is a non-invasive imaging
technique, which uses optical scanning and is especially
useful in the assessment of the retina and the adjacent
part of the vitreous body. Because of poor penetration
of the light beam into the choroid OCT can not give any
in vivo information on the histology of choroidal lesion.
On the other hand, it is possible to assess the status
and morphology of the overlying retina, which is very
important for the diagnosis and distinguishing the
naevus from a malignant melanoma, especially if the
lesion is small. |
