Evaluation of parameters for early detection of pediatric keratoconus

BMC Ophthalmology
Background Keratoconus in children is often more severe and rapidly progressive compared to adults. While Scheimpflug imaging (Pentacam) improves screening, there are no established pediatric guidelines.

Long-term results of cornea collagen cross-linking with riboflavin for keratoconus

Indian Journal of Ophthalmology, 2013
Corneal collagen cross-linking with riboflavin and UVA light (CXL) is the only method designed to arrest the progression of keratoconus. Visual improvement generally starts 3 months after treatment.

Three-dimensional ghost imaging via the Scheimpflug detection

Optics Express
For previous three-dimensional ghost imaging, the acquisition of absolute distance information is mainly based on the principle of time-of-flight, which usually needs lots of measurements and a large detection/modulation bandwidth product. Here we present a technique called three-dimensional ghost imaging via the Scheimpflug detection (3D-GISD), which ...
