Dirofilaria immitis: A cause of human intra-ocular infection

  • D. E. Moorhouse
Kasuistik

Summary

A nematode worm 8.3 mm long removed from the anterior chamber of an Australian patient's eye was identified as a femaleDirofilaria immitis. A review of another worm previously removed from the eye of another patient showed that this was also a femaleD. immitis. Both worms were subnormal in size; this is believed to be due to their development in an unnatural host. These eye infections probably result from the normal migrations of the developing worms in the subcutaneous tissues which occur prior to their entry into the venous circulation, but the exact route of entry into the eye cannot be suggested.

Dirofilaria immitis: Eine Ursache intraokularer Infektion beim Menschen

Zusammenfassung

Ein aus der vorderen Augenkammer eines australischen Patienten entfernter Fadenwurm von 8,3 mm Länge wurde als weiblicheDirofilaria immitis identifiziert. Die Überprüfung eines zuvor aus dem Auge eines anderen Patienten entfernten Wurmes ergab, daß es sich ebenfalls um eine weiblicheD. immitis handelte. Beide Würmer hatten subnormale Größe und es wurde angenommen, daß dies auf ihrer Entwicklung in einem naturfremden Wirt beruhte. Diese Augeninfektionen sind vermutlich die Folge der normalen Wanderungen der sich entwickelnden Würmer in den Unterhautgeweben, die vor ihrem Eintritt in das venöse Blut stattfinden, doch kann keine Erklärung hinsichtlich des eigentlichen Eintrittsweges in das Auge gegeben werden.
