Workup
The workup of glaucoma has also changed over time. New tonometers have appeared, but none of them has overcome the gold standard Goldmann applanation tonometer since 1957.() In 1997, the measurement of central corneal thickness (CCT) was introduced, but there is no algorithm that directly relates it to the value of IOP.(,) Also, the role of corneal hysteresis (CH) in glaucoma has not been fully elucidated. CH may be more significantly associated with glaucoma than CCT.()
OCT and OCT angiography (OCTA) have been used in last decades.(,) Diniz-Filho et al. reported that “higher levels of IOP during follow-up were associated with faster rates of RNFL loss over time measured by SD OCT”.() OCTA allows for simultaneous in vivo imaging of the morphology and vasculature of the eye.()
