From the introduction:
Tonometry is an essential measurement in the assessment of eye health and a key component of glaucoma diagnosis and treatment, with intraocular pres- sure (IOP) remaining the only modifiable risk factor for glaucoma.
From the conclusion:
Why are we persisting in using GAT clinically? The test itself is relatively time-consuming, physicians often repeat the measurement because they cannot fully trust a technician, it slows down the clinic requiring technical staff to have slit lamps and place drops in patient’s eyes and worse, it may be giving us a false sense of security. The Reichert Ocular Response Analyzer ("ORA") is a clearly better alternative that provides more information about who is getting worse. There may be other alternative tonometers comparable to the ORA that require further evaluation, but nevertheless, it is time for a change.
