Iop and pachymetry adjustment
WebIOP. Intraocular pressure measurement is influenced by corneal thickness, among other factors. Eyes with thin corneas tend to have pressures that are under-estimated by … Web(intraocular pressure, IOP). This can happen if the drainage tubes within the eye (called the trabecular meshwork) become blocked, so the fluid (aqueous humour) cannot drain out …

WebAccutome PachPen Manual Safety Precautions There are several areas in the use of the PachPen that require special attention, as they may pose a safety threat. The PachPen has an enclosure rated Degree of Protection of IP32. The enclosure provides protection for objects larger than 2.5 mm and dripping water. Web1 jan. 2002 · An increase in the corneal thickness was associated with (1) an improved AGIS score, (2) an improved mean deviation of visual field, (3) a decrease in both the vertical and horizontal cup-to-disc ratios, and (4) a decrease in the number of medications used for glaucoma (Table 1). The results of multivariable modeling are shown in Table 2.

Linear regression analysis revealed a positive correlation between CCT and IOP (r = 0.44, P<0.05). Linear regression equation: IOP = −2.35+0.032CCT, which means the IOP will increase 0.32 mm Hg for every 10-µm increase in CCT.
WebCCT were excluded. The IOP was adjusted using the correction nomogram : Corrected IOP = Applanation IOP + [5 mm Hg(mean normal - measured CCT µm) / 70 µm]. The measured IOP & corrected IOP was compared in each group and the data so obtained was analysed using the non-parametric chi square test.
