A new study conducted by a team of researchers in United Kingdom(UK) is expected to important and have effects, this study will affect the way professionals of healthcare use to measure eye pressure and is predicted to make them able to evaluate the risk of glaucoma in much higher accuracy.
Since glaucoma is known around the world to be the second commonly recognized reason of permanent loss of sight around the world, this study published in a journal under this title(Intraocular Pressure and Corneal Biomechanics in an Adult British Population — The EPIC-Norfolk Eye Study), is considered important as it takes into consideration a substantial issue, this study talks about the distribution and causes of eye pressure– medically termed intraocular pressure (IOP), it’s commonly known among researchers that the methods used in clinics for assessing eye pressure, have always the problem of being inaccurate especially as a result of the physical properties of the cornea.
But the EPIC-Norfolk study is now presenting the first large-scale population-based measures of corneal biomechanics.
An author says that in the previous time a measure which is rather hard known as (central corneal thickness) was used as an index of corneal biomechanics, but now he says that they are starting to use a device that generates measures of corneal biomechanics in conjunction with IOP and tries to correct IOP for corneal physical properties.
Recruited between 1993 and 1997, the EPIC-Norfolk cohort was made up of approximately 25,000 predominantly Caucasian men and women aged 40 to 79 living in eastern England.
In 2006 to 2010 researchers made a health examination in order to know many characteristics such as assess various physical, cognitive and ocular characteristics of participants, and these examinations were accurate and objective. As the team who conducted the research used a non-contact tonometer, and the Ocular Response Analyzer was used in order to know the pressure of the eye and also to have corneal biomechanical data from the participants who were 4,184 case aging 48-91 years old.
A doctor in the research team conducting the study said that, it was so important pieces of information to have the accurate measurements of IOP and to make an interpretation of these results in terms of what was noticed and seen in case of people who are normal, this is when the people who are professional in the health care made some routine examination to the eye, and he also added that these results will be used to assess the validity of current glaucoma treatment guidelines, with taking into consideration the levels of risk attributed to specific levels of IOP.
