Weband 19, s = 5 mmHg OS for alpacas. There were no dif-ferences between IOPs for different genders of alpacas (P 0.05), nor were there differences in IOP measure-ments between eyes within each species (P 0.05). The overall mean IOPs for llamas (33 eyes) and alpacas (46 eyes) was 16, s = 5 mmHg and 19, s = 4 mmHg, respectively. WebGoldmann applanation tonometry remains the gold standard for intraocular pressure (IOP) measurement, although numerous errors have occurred due to variability in corneal geometry, biomechanics, and tear film. 1–7 Most eye care professionals have only accepted corrections for central corneal thickness (CCT), which has been shown to be an …
WebAccurate and precise measurement of intraocular pressure (IOP) is a vitally important component of the ophthalmic examination. There are multiple methods of tonometry, each of which has considerations in light of the ongoing severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) pandemic.
