Morgagnischer Staar (morgagnian cataract)

Zuweilen soll das Trübwerden des Morgagnischen Liquor den Staar, welcher alsdann Morgagnischer Staar (Cataracta Morgagniana s. intertitialis) genannt wird, bedingen; dieses Uebel wird aber selten beobachtet, da Trübungen des Morgagnischen Dunstes schnell die Verdunklungen der Linse bedingen.

“The characteristic facial expression of the onchocerciasis patients is also based on the interstitial keratitis, which prefers a horizontal axis and creates a vertical positioned ovular bow in the ribbon shaped degeneration of the cornea”.
