Background and study aims Eyes contain a jelly-like liquid called vitreous. When a patient is having surgery on their retina (the part of the eye where light signals are sent to the brain to create an image) this liquid has to be removed in order to gain access. This surgical procedure is known as a plars plana vitrectomy. During this procedure, vitreous needs to be replaced with a saline (salt water). In some cases, the retina can become detached from the eye and so silicone oil tamponade (gel) may be used to keep the retina in place. Silicone oil carries heat differently to water and these heat changes can lead to blurred vision. This study aims to compare eye temperature in participants who have an eye with silicone oil tamponade and an eye without it, in order to determine if silicone oil affects the temperature. Who can participate? Adults who are having a pars plana vitrectomy using silicone oil tamponade as part of their normal care. What does the study involve? The temperature of each participant’s cornea (the out layer of the eye) is measured using a handheld non-contact thermometer in both eyes. This involves shining a special light into the eye which measures the temperature. Three temperature readings from each eye are taken. Participants also have their overall body temperature (taken from their forehead) measured using the same method. What are the possible benefits and risks of participating? There are no direct benefits or risks to those taking part in the study. Where is the study run from? Istanbul Education and Research Hospital (Turkey) When is the study starting and how long is it expected to run for? November 2015 to May 2016 Who is funding the study? Investigator initiated and funded (Turkey) Who is the main contact? Dr. Erkan Unsal [email protected]
