Hand-held Optical Coherence Tomography Feasibility Older Hip Fracture

Study Overview
=================
Brief Summary
-----------------
Assessment of the feasibility of achieving retinal imaging in older people with recent hips fracture surgery using hand held optical coherence tomography device

Detailed Description
-----------------
Optical coherent tomography (OCT) is a device used to achieve cross-sectional imaging of tissues. It is often used in ophthalmology and also has application in dermatology, cardiology and other specialities. Usually, in adults, a table-top device is used necessitating the transfer of patients to the location of the device. In children a hand held device is used meaning the device can be taken to the patients' location. To facilitate/ help design a future study, this study's aim is to assess the feasibility of achieving retinal imaging in older people who are recovering from hip fracture surgery using a hand held device.
