Deep learning-based keratoconus detection from Scheimpflug images

Biomedical Optics Express
This study evaluates the effectiveness of deep learning techniques applied to raw Scheimpflug corneal images for keratoconus detection, with a particular focus on forme fruste (FF) keratoconus, which refers to preclinical cases. Using an original dataset of 22,750 images from 910 eyes, a deep learning model based on transfer learning with a pre-trained

Transfer Learning-Based Keratoconus Detection from Scheimpflug Images

Jornada de Jóvenes Investigadores del I3A
Preclinical detection of keratoconus is crucial to avoid irreversible corneal damage associated to refractive surgery for laser myopia correction. This work proposes, for the first time, a deep learning-based approach for preclinical keratoconus diagnosis using corneal images. Our model, trained in 22,750 images, achieved an overall accuracy of 90.70%,

Clinical applications of Scheimpflug imaging

Expert Review of Ophthalmology, 2009
Since the Scheimpflug principle was first described more than a century ago, there has been great interest among ophthalmologists in the use of Scheimpflug cameras in anterior-segment imaging. Scheimpflug cameras have advanced significantly and modern-day instruments provide comprehensive imaging and topographic data of the anterior segment.
