[Ultrastructural changes in the retina under althesin anesthesia].

Effect of Althesin-mononarcosis of 1--4 hours of duration on the ultrastructure of retina has been studied. In neural elements of the retina pathologic changes have not been observed. Only one unusual phenomenon-increase of glycogen content in Müller cells parallel with the duration of the narcosis has been noticed. Author believes that this phenomenon can be regarded as physiological reaction occurring in sleep.
