Abstract:
Marfan syndrome is classified as a heritable disorder of connective tissue, and it has been assumed to be an inborn error of protein metabolism particularly in collagen or elastin. We examined 41 Marfan syndrome patients and found in the corneal endothelium guttata-formation, considerable cell pleomorphism, non-reflecting endothelial black spots and in some cases abnormal looking endothelial cells. The relation of pathological endothelium to lens subluxation, axial length and other corneal findings is discussed.
Insights
Marfan syndrome, a connective tissue disorder, may involve abnormal corneal endothelium. This study observed guttata-formation and cell abnormalities in Marfan patients, suggesting a link to ocular manifestations.
Area of Science:
- Ophthalmology
- Genetics
- Connective Tissue Diseases
Background:
- Marfan syndrome is a heritable connective tissue disorder.
- It is often linked to protein metabolism errors, particularly in collagen or elastin.
- Ocular manifestations are common in Marfan syndrome.
Purpose of the Study:
- To investigate corneal endothelial findings in patients with Marfan syndrome.
- To explore the relationship between pathological endothelium and other ocular features.
Main Methods:
- Examination of 41 patients diagnosed with Marfan syndrome.
- Detailed analysis of corneal endothelium morphology.
Main Results:
- Guttata-formation was observed in the corneal endothelium.
- Significant cell pleomorphism and abnormal endothelial cells were noted.
- Non-reflecting endothelial black spots were present in some patients.
Conclusions:
- The corneal endothelium in Marfan syndrome patients exhibits distinct pathological changes.
- These endothelial abnormalities may correlate with lens subluxation and other corneal findings.
- Further research is warranted to understand the full spectrum of ocular involvement.
