[Metabolic changes in the retina after experimental microembolism in the miniature pig (author's transl)]

Experimental microembolisation provokes hemodynamics and metabolic changes in the inner retina. The metabolic modifications are the consequence of focal tissue ischaemia and have as a main feature, the activation of anaerobic glycolysis. This activation produces an increase in the production of lactic acid which, in turn, causes a drop of tissular pH. Choroidal circulation maintains photoreceptors in a physiological state.
