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

Condition or disease Intervention/treatment Phase
Retinal Imaging Diagnostic Test: Optical coherence tomography Not Applicable

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.

Arm Intervention/treatment
Experimental: All participants
All participants will have measurements taken. There are no comparators or controls in this feasibility study
Diagnostic Test: Optical coherence tomography
Non-invasive method of acquiring cross sectional imaging of tissues using the coherent property of light
Other Name: OCT

Primary Outcome Measures :
  1. Ability to achieve good quality retinal images [ Time Frame: 30 minutes ]
    Retinal images with signal strength > 6 and in which retinal layers can be measured

  2. Ability to achieve imaging without causing pain [ Time Frame: Immediate ]
    Patient reported pain during acquisition of images over their baseline. Scale of 0 - 10 where 0 is no increase in pain and 10 is severe increase in pain
