Eye imaging data from different device vendors often come in different file formats. Additionally, public datasets often have their own way of storing data for distribution. The lack of documentation for many device-specific formats is a problem already when working with a single data source while the pure amount of different formats slows down everyone trying to use data from multiple sources. This Python package aims at providing a unified interface to a wide variety of eye imaging formats and the execution of standard tasks such as data visualization and quantification on ETDRS grids. Thereby, it enables the development of device-independent software and algorithms.
