Radiological and non-radiological imaging
Six cases had neuro-imaging. Of these, 3 cases had cranio-orbital CT scans, 2 cases had magnetic resonance imaging (MRI) of the brain and 1 case had MRI of the spine. Three cases had orbito-ocular ultrasonography (B-scan); retinal detachment was diagnosed in two cases, while the third B-scan showed a resolving haematoma, in a patient with suspected plexiform neurofibroma and a recent history of trauma. One patient with scoliosis, had plain radiograph of the spine. Majority of cases however, did not perform radiological investigations. Neuro-radiological diagnoses are listed in Table 1. More advanced forms of ophthalmological imaging such as Optical coherence tomography (OCT), indocyanine-green and fluorescein angiography, as well as, infrared and near-infrared reflectance imaging are not available in our environment and therefore were not used.
