Conclusions
In prolonged insulin coma of 10 days duration:
-
1.
The retina appears to escape damage, although the brain sustains extensive injury.
-
2.
The ophthalmoscope reveals no gross pathology. This finding supports one reported in a previous paper—that the fundi are negative in functional psychoses surviving routine insulin shock therapy.
-
3.
The intraocular tension remains uniformly low, and fluctuates inexactly with the spinal pressure.
-
4.
The intraocular tension has no relation to the blood pressure, or blood and spinal sugar levels.
-
5.
The finding of lowered intraocular tension corresponds to that of most investigators who report the same in routine insulin comas of short duration.
