102 There might be fewer repeatability Together with the RT, in comparison with GAT, because the former has this sort of brief connection with the ocular area. The looking at acquired can be of any level throughout the IOP pulse cycle.107 However, Davies et al107 did realize that the intersession repeatability of your RT was akin to other non-GAT devices, as an example, the Tono-Pen and the NCT.
