Summary

Pseudoexfoliation syndrome appears to be a genetically transmitted, late-onset autosomal dominant trait. This condition shows variable expression, with age being a significant risk factor.

Area of Science:

  • Ophthalmology
  • Genetics
  • Gerontology

Background:

  • Pseudoexfoliation syndrome is an inherited condition affecting the eye.
  • Understanding its genetic transmission is crucial for early diagnosis and management.

Purpose of the Study:

  • To investigate the occurrence and inheritance patterns of pseudoexfoliation syndrome in three families from Gozo.
  • To identify potential risk factors and clinical manifestations within these families.

Main Methods:

  • Ophthalmologic examinations were conducted on 55 individuals from three families with a high incidence of pseudoexfoliation.
  • Family history and clinical records were reviewed.
  • Pseudoexfoliation status was classified as present, absent, or unknown.

Main Results:

  • Eighteen out of 55 individuals exhibited pseudoexfoliation, predominantly in those over 60 years old.
  • Clinical manifestations varied, with some families showing high rates of cataract and glaucoma.
  • Maternal transmission was not evident, but paternal involvement was noted in the first generation.

Conclusions:

  • Pseudoexfoliation syndrome in these families suggests a late-onset autosomal dominant inheritance pattern with variable expressivity.
  • Age is a significant risk factor for developing pseudoexfoliation syndrome.
  • Further research is needed to confirm the genetic basis and explore potential environmental influences.
