Question: Question: Does hydrostatic pressure cause detectable changes in survival of human retinal ganglion cells?
Answer: Directly applied HP had no detectable impact on RGC survival and stress-signalling in HORCs. Simulated ischemia, however, activated stress pathways and caused RGC death. These results show that direct HP does not cause degeneration of RGCs in the ex vivo human retina.
