Patients who are found to have elevated IOP on non-contact tonometry testing are expected to have Goldman or Perkins applanation
tonometry pressure refinement carried out at the same visit.
Another key aspect of Visit 3 is being observed performing Goldmann or Perkins applanation
Keratometry was done on Haag-Strait manual keratometer and A-scan was done by applanation
contact method on SonoMed machine.
The IOP measured by the gold standard method, Goldmann Applanation
Tonometry (GAT) is based on the assumption that CCT is 520 [micro]m.
Objective: To determine the correlation between mean central corneal thickness taken with Galilei dual Scheimpflug Analyzer and Applanation
Their IOPs were measured with Goldmann applanation
27 mm/min, and mean intraocular pressure measured via applanation
tonometry was 10.
1) concluded that "Because Tono-Pen (TP) measurements were lower than Goldmann applanation
tonometer (GAT) measurements and non-contact tonometer measurements were higher than GAT measurements, patient follow-ups, treatment strategies, and surgery plans must be organized taking these differences into consideration".
However, more recent data suggest that 3% hydrogen peroxide and 70% isopropyl alcohol are not effective against adenovirus capable of causing epidemic keratoconjunctivitis and similar viruses and should not be used for disinfecting applanation
Intraocular pressure (IOP) was measured with Goldmann applanation
tonometer (GAT) and peripapillary RNFL thickness was measured in four quadrants with SD-OCT (Topcon 3D OCT-1000 Mark II) in all subjects.
Intraocular pressure was measured awake using Goldmann applanation
tonometer or under general anesthesia when patients were uncooperative for evaluation.
In animais, both applanation
and rebound tonometry are used, and correlation has been revealed between these methods (KNOLLINGER et al.
