Purpose To evaluate the effect of acute intraocular pressure (IOP) increases on the intrastromal corneal pressure (ICP). Methods The ICP and the central corneal thickness (CCT) were measured, “in vivo”, in 9 rabbit eyes with stable IOP, and in 9 rabbit eyes at baseline, and then after the IOP was set at 15mmHg and at 30mmHg. Results The ICP reached similar levels in both groups at all time points (p=0.5, p=0.9 and p=0.6, respectively) although the CCT was significantly thinner (p=0.02) with higher IOP levels. Conclusion The ICP, measured by intraestromal cannulation, tends to become more negative with time, and this behaviour does not change with the increase of IOP, in the range analyzed, even though the cornea shows the expected IOP‐induced compression.
