Abstract
BackgroundThe conventional fundus imaging covers up to 60 degrees of retina only. Although various montaging techniques can significantly increase the area that can be imaged, it is still difficult to image and document the peripheral retina. The purpose of this study is to describe the use of ultra‐wide field imaging in the diagnosis and management of adult‐onset Coats’ disease.MethodsThis is a retrospective case series of three patients diagnosed with adult‐onset Coats’ disease that were treated at the retina clinic of our institute. The case records, conventional and ultra‐wide field fluorescein angiograms and optical coherence tomography scans were reviewed.ResultsThe ultra‐wide field pseudo‐colour photographs and fluorescein angiograms were able to provide clinically useful information over and above that provided by conventional imaging. In all three patients, ultra‐wide field angiography showed the temporal avascular periphery. In addition, it revealed retinal neovascularisation, peripheral vascular leakage and documented peripheral telangiectasia in selected patients.ConclusionUltra‐wide field imaging provides information that can help in the diagnosis and management of adult‐onset Coat's disease. This may lead to better visual outcomes in Coats’ disease.
