A Case of Choroidal Naevus in a Child
Choroidal naevus is the most common benign intra-ocular tumour. It originates from neural crest derived cells. This lesion is of clinical significance due to risk of visual loss especially if located near the foveola and risk of transformation into malignant melanoma. Traditionally choroidal naevus has been assessed using ultrasound and fluorescein angiography. With advent of new imaging modalities like optical coherence tomography (OCT), fundus autofluorescence (FAF) and OCT angiogram (OCTA) they are being more commonly used to assess naevus. Low risk naevus is defined as one that is unlikely to transform into melanoma. Features of low-risk naevi are thickness <2mm, presence of drusen, absence of subretinal fluid, absence of orange pigment, absence of symptoms, tumour margins away from optic disc, and echo dense on ultrasound. It is a common observation that choroidal naevi are rarely seen in younger children. We describe a case of choroidal naevus in a 16-year-old girl referred to our clinic and review of literature to assess its prevalence and outcome in children.
