Imaging in ophthalmology has changed faster than our understanding of what these images might mean. The magnitude of the images taken in clinical and research setting and subsequently received for analysis was initially limited by the speed of the slides being developed or by the quality of the polaroids. The last 20 years have seen an unprecedented rise both in the number and the quality of digital images in ophthalmology.
The Ophthalmic Image Analysis Centres (commonly referred to as Reading Centres) now mainly deal with digital images. In broad terms, these come from three sources: screening/clinical settings, epidemiological studies and clinical trials. The requirements for these three are governed by different principles and the time and money involved are vastly different as well. Screening/clinical setting requires fast but reliable approaches some with immediate decision making, others can be slightly delayed, but usually only by days. Epidemiological studies examine thousands of patients and require reliable and reasonably cheap solutions, especially as many patients exhibit no pathology. Clinical trials demand rigorous and time-honoured grading approach with exhaustive quality control approaches.
Both clinicians and researchers have been looking for (semi)automated approaches in order to be able to provide faster and more reliable care to patients with the elimination of at least part of the human factor.
During this seminar we will discuss the clinical and research requirements of image analysis in ophthalmology.
Biography
Dr Tunde Peto is the Founding Head of the Reading Centre at the NIHR Biomedical Research Centre for Ophthalmology, at Moorfields Eye Hospital NHS Foundation Trust and UCL Institute of Ophthalmology. This RC is currently involved at all levels of imaging work: screening/clinical, epidemiology and clinical trials.
Dr Tunde Peto is a practising ophthalmologist with special interest in blinding conditions such as diabetes, age related macular degeneration, glaucoma amongst others. Dr Peto’s Master thesis is on health education while her PhD is in epidemiology and statistics on the field of diabetes care. During her training she started working on image analysis, first on the Blue Mountains Eye Study in Australia and then as her interest grew in the field, so did her involvement. She is a Board member of several prestigious ophthalmic societies. Dr Peto’s epidemiology work allows her to have a good understanding of the challenges faced by different populations.
