A new test to check eye pressure could potentially help to prevent vision loss in elderly patients, according to a new study.
The University of Missouri School of Medicine has indicated that testing the pressure of the eye with a device called a tonometer can improve the current standard of care for older people undergoing cataract surgery.
In this study, 170 patients who had their eye pressure adjusted after cataract surgery with a tonometer were found to be 2.5 to four times less likely to develop cystoid macular oedema, an eyesight-impairing condition characterised by cyst-like pockets of fluid developing in the macula.
Tonometers can result in considerable savings in terms of the reduced need for medications and eye drops used to treat retinal swelling or oedema, while a lower-cost pressure ring can also be used as an effective alternative tool to measure eye pressure.
Dr John Jarstad, associate professor of ophthalmology at the University of Missouri School of Medicine, said: "There is no additional cost to patients, and if it saves just one patient from going blind, it would be well worth every doctor using it in his or her surgical practice."
