Intraocular Pressure Disorder Clinical Trial
Official title:
The Effects of Virtual Colonoscopy on Intraocular Pressure
Our trial examined the intraocular pressure measurements differences, before and after virtual colonoscopy examination.
Glaucoma is a complicated disease in which damage to the optic nerve leads to progressive,
irreversible vision loss. Glaucoma is the second leading cause of blindness and associated
with elevated intraocular pressure (IOP) as a major risk factor.
IOP is influenced by many factors, including ethnicity, heredity, various chemical
substances (existing body and external body like drugs), physical changes (postures, neural
and vascular autoregulation) and more.
Virtual colonoscopy is a common screening test for the early detection and diagnosis of
colon cancer. The test is performed by computed tomography (CT) after inflating the colon
with carbon dioxide (CO2) gas. The procedure is performed by inserting a Foley catheter
through the anus. As a result of gas inflating of the bowel, consequently, there is an
increase in the abdominal pressure.
Raising intra-abdominal pressure may cause a rise in intraocular pressure. The aim of this
research is to examine the changes in IOP before and after the virtual colonoscopy, with the
aim to improve the understanding of the relationship between intra-abdominal pressure and
IOP.
The study will include 100 patients, men and women, that are scheduled for virtual
colonoscopy test both in a hospital and in ambulatory.
