Pseudoexfoliation, an environmental disease?

H R Taylor

    Transactions of the Ophthalmological Societies of the United Kingdom
    |July 1, 1979

    Summary
    This summary is machine-generated.

    Pseudoexfoliation (PXF) may be an environmental disorder linked to solar radiation, not just genetics. Research in Australian Aborigines suggests environmental factors influence PXF prevalence.

    Area of Science:

    • Ophthalmology
    • Environmental Health
    • Genetics

    Background:

    • Pseudoexfoliation (PXF) is often considered a genetically determined condition.
    • Geographical variations in PXF distribution have historically supported a genetic hypothesis.
    • Australian Aborigines exhibit a high prevalence of PXF, particularly in older individuals.

    Purpose of the Study:

    • To investigate potential associations between personal and environmental factors and PXF in Australian Aborigines.
    • To explore alternative hypotheses beyond genetic determination for PXF.

    Main Methods:

    • A detailed examination of 350 Australian Aborigines.
    • Analysis of personal factors (age, sex, occupation) and environmental factors (latitude, global radiation).

    Main Results:

    • PXF prevalence increased with age and was three times higher in males than females.
    • A significant association was found between PXF and stockmen occupations.
    • PXF was more common at lower latitudes and with higher global solar radiation levels.

    Conclusions:

    • Findings suggest PXF may be an environmental disorder, potentially caused by solar radiation.
    • Environmental factors, including solar radiation exposure, warrant further investigation in PXF pathogenesis.
