Neurofibromatosis type 1 (NF1) is a common autosomal dominant disorder, caused by mutations in the NF1 gene, located on chromosome band 17q11.2. In 1988, the National Institutes of Health created specific criteria for the diagnosis of NF1. Four cardinal criteria are assessed through ophthalmological screening: Lisch nodules, optic pathway glioma, a(More)
Cytomegalovirus (CMV) is the leading cause of known congenital viral infections. Approximately 90% of congenitally infected newborns exhibit no clinical abnormalities at birth. In 5% to 15%, a wide spectrum of clinical signs is present at birth. Ophthalmological signs are seen in a large percentage of symptomatic patients but rarely in otherwise(More)
PURPOSE To characterize the choroidal thickness of the papillomacular region in young healthy individuals using spectral-domain optical coherence tomography (SD-OCT). METHODS Papillary and macular SD-OCT scans were obtained using an enhanced depth imaging mode. Digital retinography was used to assess any overlapping areas and to determine the(More)
We present a newborn diagnosed with posterior amorphous corneal dystrophy (PACD). PACD is a rare disorder with partial or complete posterior lamellar corneal opacification. Genetic screening showed a deletion of chromosome 12q21.33-q22 containing the identified four small leucine-rich proteoglycans (SLRP's) associated with this particular dystrophy. Neither(More)
The aim of this study is to investigate the role of pattern reversal visual evoked potentials (pVEPs) in the screening and monitoring of optic pathway gliomas (OPGs) in children with and without neurofibromatosis type 1. A review of the English literature published between 1980 and 2012 was performed, with comparison of results of retro- and prospective(More)
PURPOSE Efforts are made to unify the protocol concerning the ophthalmological screening, monitoring and treatment of Optic Pathway Gliomas (OPGs) in children with neurofibromatosis type 1 (NF1). The aim of this study is to compare the most recent recommendations published in 2007 with the screening strategies in NF1 centres. The integration of these data(More)
Enhanced S-cone syndrome is a rare, slowly progressive autosomal recessively inherited retinal degeneration related to mutations in the NR2E3 gene. Patients often present with night blindness, visual loss and visual field abnormalities. Patients with enhanced S-cone syndrome exhibit a variable clinical phenotype associated with various degrees of pigmentary(More)
BACKGROUND Paraneoplastic melanocytic proliferation (bilateral diffuse uveal melanocytic proliferation, BDUMP) is a rare but devastating disease that causes progressive visual loss in patients who usually have an occult malignancy. Visual loss occurs as a result of paraneoplastic changes in the uveal tissue. METHODS In a masked fashion, the serum of two(More)
The best known café-au-lait syndrome is neurofibromatosis type 1 (NF1). Legius syndrome (LS) is another, rarer syndrome with café-au-lait macules (CALMs). In young patients their clinical picture is often indistinguishable. We investigated the presence of choroidal abnormalities in syndromes with CALMs as a candidate tool for a more efficient diagnosis.(More)
Thank you for your comments on our article. Nearinfrared autofluorescence for the detection of choroidal nodules is indeed interesting, helping us to confirm the diagnosis of NF1, when uncertain. We believe these lesions are not good indicators of glioma formation or growth; this is the main reason why we perform ophthalmological examinations. Since these(More)
