Shared molecular profiles of post-laser vision correction ectasia and keratoconus with key differences in CADPS, CPT1B, CIITA, and TBC1D4 [PDF]

Frontiers in Molecular Biosciences
IntroductionPost-laser vision correction (post-LVC) ectasia is a serious complication that is observed in 0.033%–0.66% of corneal refractive surgeries. Similar to keratoconus (KTCN), post-LVC ectasia is classified under the category of “ectatic diseases.”

A Deep Learning-Based Graphical User Interface for Predicting Corneal Ectasia Scores from Raw Optical Coherence Tomography Data [PDF]

Diagnostics
Background/Objectives: Keratoconus, a condition in which the cornea becomes thinner and steeper, can cause visual problems, particularly when it is progressive. Early diagnosis is important for preserving visual acuity. Raw data, unlike preprocessed data,

Deep Learning-Based Diagnosis of Corneal Condition by Using Raw Optical Coherence Tomography Data [PDF]

Diagnostics
Background/Objectives: Keratoconus (KC) is the most common corneal ectasia. This condition affects quality of vision, especially when it is progressive, and a timely and stage-related treatment is mandatory.
