The system is based on the idea that little variations in ocular circumference measured at the corneoscleral junction correspond to alterations in IOP and intraocular volume.one hundred twenty five Manometry research in enucleated eyes have demonstrated that the system’s sign correlates properly with pop over to this web-site true IOP, but related experiments in vivo haven't been finished.

102 There may be a lot less repeatability Along with the RT, as opposed with GAT, since the previous has these kinds of brief connection with the ocular surface. The reading through obtained could be of any point over the IOP pulse cycle.107 Nonetheless, Davies et al107 did find that the intersession repeatability of the RT was akin to other non-GAT devices, by way of example, the Tono-Pen and the NCT.
