Ultrastructure of exfoliation material (Busacca deposits)

  • Amund Ringvold
Article

Summary

The peripheral exfoliation band was scraped from seventeen lenses that were removed because of senile cataract. A suspension of the exfoliation substance, negatively stained with sodium silicotungstate, was studied and compared with the sectioned exfoliation material.

It is concluded that the exfoliation substance probably consists of a collagen material, that perhaps comes from basement membranes.

Zusammenfassung

Bei 17 Augenlinsen, die wegen einer senilen Katarakt extrahiert worden waren, wurde das periphere Exfoliationsband abgeschabt. Suspensionen dieses Materials wurden elektronenmikroskopisch nach einer Negativ-Färbung mit Natrium-Kieselsäure-Wolframsalz untersucht und die Befunde mit geschnittenem Exfoliationsmaterial verglichen. Aus den Untersuchungsergebnissen wird der Schluß gezogen, daß die Exfoliationssubstanz wahrscheinlich aus einem kollagenen Material besteht, welches möglicherweise von der Basalmembran abstammt.
