Attrition und Osmokinetik – Zwei Konzepte zur Pathogenese des Trockenen Auges

Abstract: ZusammenfassungDie neuen Erkenntnisse der Pathophysiolgie des Trockenen Auges erkennen das Zusammenspiel von Tränen, Augenoberfläche und Lidoberfläche als eine funktionelle Einheit an. Der Begriff der Benetzungsfähigkeit der Tränen in Abhängigkeit der mikrotektonischen Anatomie der Augenoberfläche relativiert die Anforderungen an Träne und Tränenersatzmittel. Das Model der Attrition, welches die Effekte der friktionsneutralisierenden Kapazität des Tränenfilms, der Reibung und die Bedeutung der Mechanotransdukt… Show more

“…Cell stress is an essential cellular biological equivalent of stress resulting from lubrication insufficiencies and environmental changes. At present, in dry eye disease, this dominantly contributes to mechano-stimulation such as attrition and friction [ 71 , 72 ], challenging osmotic deviations, as well as hyperosmolarity.…”

“…Another stress factor, hyperosmolarity itself has been suggested to be a driving force within the vicious circle [ 10 ], albeit that recently, the models on osmokinetics and osmotic variation [ 71 , 123 ] have given more consideration to the importance of osmotic alterations. In osmokinetics, both the amplitude and level around which DVO pivots are suggested to contribute to the intensity of stress provoked [ 72 ] and with that, the impact on heterostasis. Within the current model of ocular surface homeostasis, this would suggest an osmotic equilibrium in the tear film hovering around the normal osmolarity with values of around 305 mosmol/L [ 124 , 125 , 126 ].…”
