Keratoconus detection using corneal topography.
UNLABELLED PURPOSETo review the topographic patterns associated with keratoconus suspects and provide criteria for keratoconus screening. METHODS Case study using maps from the NIDEK OPD-Scan II and OPD Station to highlight patterns seen in keratoconic corneas. RESULTS Five criteria are listed for the detection of keratoconus: 1) apex of the cone is not centered at the 6-o'clock semi-meridi...
متن کاملAutomated keratoconus screening with corneal topography analysis.
PURPOSE Although visual inspection of corneal topography maps by trained experts can be powerful, this method is inherently subjective. Quantitative classification methods that can detect and classify abnormal topographic patterns would be useful. An automated system was developed to differentiate keratoconus patterns from other conditions using computer-assisted videokeratoscopy. METHODS Thi...
متن کاملCorneal topography indices after corneal collagen crosslinking for keratoconus and corneal ectasia: one-year results.
PURPOSE To evaluate changes in corneal topography indices after corneal collagen crosslinking (CXL) in patients with keratoconus and corneal ectasia and analyze associations of these changes with visual acuity. SETTING Cornea and refractive surgery subspecialty practice. DESIGN Prospective randomized controlled clinical trial. METHODS Corneal collagen crosslinking was performed in eyes wi...
متن کاملNeural network classification of corneal topography. Preliminary demonstration.
PURPOSE Videokeratography is a powerful tool for the diagnosis of corneal shape abnormalities. However, interpretation of the topographic map is sometimes difficult, especially when pathologies with similar topographic patterns are suspected. The neural networks model, an artificial intelligence approach, was applied for automated pattern interpretation in corneal topography, and its usefulness...
متن کاملCorneal topography in keratoconus: state of the art.
The morphological characterization of the cornea using corneal topographers is a widespread clinical practice that is essential for the diagnosis of keratoconus. The current state of this non-invasive exploratory technique has evolved with the possibility of achieving a great number of measuring points of both anterior and posterior corneal surfaces, which is possible due to the development of ...
