Retinal tumours in neurofibromatosis.

M Turek, E R Raistrick, C D Hart

    Canadian Journal of Ophthalmology. Journal Canadien D'Ophtalmologie
    |January 1, 1977
    PubMed
    Summary

    A patient with neurofibromatosis displayed retinal hamartomas, resembling those in other phakomatoses. This suggests retinal changes in neurofibromatosis are intermediate between Bourneville’s and von Hippel-Lindau’s diseases.

    Area of Science:

    • Ophthalmology
    • Genetics
    • Neurology

    Background:

    • Neurofibromatosis, also known as von Recklinghausen's disease, is a genetic disorder characterized by the growth of tumors along nerves.
    • Phakomatoses are a diverse group of congenital, hereditary diseases that affect the brain, spinal cord, eyes, and skin.
    • Retinal manifestations are recognized in several phakomatoses, including Bourneville's disease (tuberous sclerosis) and von Hippel-Lindau's disease.

    Observation:

    • A 45-year-old male diagnosed with von Recklinghausen's disease presented with unique hamartomatous lesions in his retinae.
    • The observed retinal lesions shared similarities with those typically documented in Bourneville's disease and von Hippel-Lindau's disease.

    Findings:

    • The presence of these specific retinal hamartomas in a patient with neurofibromatosis is a significant clinical observation.
    • These findings support the hypothesis that the spectrum of retinal changes in neurofibromatosis is positioned intermediately between the ocular findings of Bourneville's disease and von Hippel-Lindau's disease.

    Implications:

    • This case expands the understanding of the phenotypic variability within neurofibromatosis.
    • It highlights the importance of comprehensive ophthalmological examination in patients with phakomatoses to detect diverse retinal abnormalities.
    • Further research into the molecular mechanisms underlying retinal hamartoma formation in different phakomatoses may reveal shared pathways or distinct pathogenetic processes.
