Application of neural networks to the classification of photorefraction images
N
eural networks are successfully being used for many years in a large number of fields of science and technology also in
medicine and virtually all fields of knowledge. Even in simple non advanced ways the results of the application of neural
networks to a number of problems give good and reliable results comparable and most often better than traditional methods.
In the work herein we report an application to an optometry problem: The automated classification of digital photorefraction
images was obtained to characterize the refractive status of patients, mostly young children. The importance of an early
evaluation of the condition of the visual system of infants is long time recognized. Non corrected optometric or ophthalmologic
problems may lead to major vision and developmental non-reversible limitations in the future. Among the objective methods
of refraction photorefractive techniques are specifically designed for screening young children. Over the years a number of
photorefraction systems with different grades of complexity and automation were developed. One critical problem that needs
to deal with in any approach of these systems is the interpretation and classification of the photorefraction images.
