Corneal thinning has further clinical relevance for glaucoma in that the use of prostaglandin analogs (PAs) and other topical glaucoma medications have been associated with reduced CCT. 1963 Jul;2:274-83. Dont place too much fluorescein into the eye, which will make the mires too thick (left) and cause the IOP reading to be too high. DONT use contact tonometry on those with active corneal disease.Use non-contact methods, like Tono-Pen, Icare or NCT, on patients with active corneal infections or corneal epithelial defects. Many patients prefer it because the machine doesn't physically contact the cornea.

Two recent studies explore the link between central corneal thickness (CCT) and glaucoma, underscoring the need to perform baseline CCT readings before and during glaucoma treatment. New York: McGraw-Hill; 2015:289-300. In those cases, you really want to be sure that you do the central corneal thickness measurement as part of the intraocular pressure assessment, so you can put it in perspective and say, Ah, his pressure is normal today, its 18mm Hg; but thats kind of borderline, and maybe that 18mm really is 22mm because his cornea is thinner. Dr. Perl says. A Perkins tonometer resembles a GAT and uses the same applanating prism, but is portable and can be used on patients who are not being tested with a slit lamp in the office, those with physical limitations preventing them from positioning in a slit lamp and those being tested in the supine position. Physical properties of the ocular surfaceparticularly corneal resistance and surface tension of the tearshave a practical influence on applanation measurements.7 Various methods of IOP measurement employ applanation tonometry, including: Goldmann applanation tonometry (GAT), introduced in the 1950s, is currently regarded as the reference standard. Instead of using GAT for patients with astigmatism, consider using the Tono-Pen, a pneumotonometer or other devices if a patients cornea is significantly irregular (from refractive error, scarring, ectasia, etc.). The Pascal Dynamic Contour Tonometer (Ziemer) uses a curved probe, larger than a GAT tip, to measure IOP via hydrostatic coupling; it has demonstrated exceptionally accurate measurements compared with other current methods.6 This method also takes into account corneal properties, but does take longer to perform (approximately 2.5 minutes) than other methods.6.
