In addition, naturally thin corneas are an independent risk factor for glaucoma, so measurement of corneal thickness is part of a comprehensive eye exam and should be performed at your initial and/or subsequent visits.

IOP is often measured with applanation tonometry, where a small constant area of the clear cornea at the front of the eye is flattened and the force required to do so is converted into a pressure reading. Eye doctors measure eye pressure because elevated pressureaka ocular hypertensioncan damage the optic nerve and cause permanent vision loss..

One study found the IOP was best measured at a different angle, approximately 43 from the major axis of astigmatism (in minus cylinder), which is marked on the Goldmann tonometer prism holder with a red line.3 If the prism orientation adjustment is not made, the different curvatures of the cornea will influence the IOP reading; low IOP readings will be recorded with with-the-rule astigmatism, and higher readings will be recorded with against-the-rule astigmatism.1 Take note, the mires will appear obliquely oriented and may be more difficult to adjust because the slit lamp does not have the capability to adjust the mires diagonally. These disposable prisms can also eliminate the need to disinfect the tonometer prism between each patient and decreases the risk of spreading infection. Results : Side effects, warnings and precautions, safety information, and pregnancy and breastfeeding safety information should be reviewed prior to taking any medication.

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. For example, the Triggerfish (Sensimed) contact lens contains sensors to monitor changes in the curvature of the cornea, which researchers presume is affected by IOP changes; however, the findings have yet to be validated. Normal Eye Pressure Range By Age What is good eye pressure? Glaucoma is the gradual death of nerve fibers at the back of the eye that carry visual information from the eyes to the brain, resulting in a loss of peripheral vision and, if severe and left untreated, eventual complete loss of vision.
