Abstract Details
Purpose:
To determine if images obtained using a digital compact digital camera (CDC) be used for accurate grading of PCO (posterior capsule opacification (PCO).
Setting:
Sussex Eye Hospital, Brighton and Sussex University Hospitals NHS Trust, Brighton, UK..
Methods:
A cross-sectional study was carried out recruiting patients with PCO from dedicated Nd:YAG laser clinics. One eye from each patient was photographed 3 times: once by the dedicated anterior segment slit lamp camera (ASSC) and twice by a compact digital camera (CDC) by a single examiner. The PCO image captured was graded using EPCO, a PCO grading software. Masked grading was carried out using two separate graders, different from the examiner. Bland-Altman’s coefficient of repeatability was tested for the PCO scores obtained from the two images from the compact digital camera, and limits of agreements were also assessed.
Results:
63 eyes of 63 patients were assessed. Mean EPCO grading for Anterior Segment photography over all eyes was 2.28 (Range 0.83 - 3.73). Mean EPCO score for images with a Nikon Coolpix compact camera was 2.28 ( Range 0.76 - 3.55) for the first image acquired, and 2.28 (Range 0.77 - 3.61) for the second image.
Bland-Altman plots demonstrate close good agreement between anterior segment and compact camera images.
Conclusions:
This study demonstrates that compact cameras are comparable to expensive traditional anterior segment cameras, and may be used in the grading of PCO in the clinical and research setting. Using digital compact cameras for anterior segment photography can be cost effective for clinics and researchers
