Atlas Entry Keratoconus

Atlas Entry Keratoconus Keratoconus is a bilateral corneal ectasia characterized by central thinning and bulging of the cornea resulting in a cone shaped protrusion. this patient demonstrates multiple characteristic signs of the condition. Topography maps the surface curvature of the anterior cornea via the projection of keratoscopic rings (mires) (devices such as the orbscan and atlas). tomography maps both the anterior and posterior surfaces of the cornea (devices such as the pentacam and galilei).

A keratoconus screening system provides information on the potential risk of keratoconus and classifies each patient’s cornea into one of the following groups: keratoconus, keratoconus suspect, normal or treated. Purpose: to develop a novel method based on biomechanical parameters calculated from raw corneal dynamic deformation videos to quickly and accurately diagnose keratoconus using machine learning. Figure 2 atlas topography of the patient with keratoconus at age 12. in this patient with keratoconus, the curvature map shows irregular astigmatism that is asymmetric in presentation.

Figure 2 atlas topography of the patient with keratoconus at age 12. in this patient with keratoconus, the curvature map shows irregular astigmatism that is asymmetric in presentation. The atlas corneal topography (carl zeiss meditec ag, jena, germany), vhf digital ultrasound epithelial thickness profile, and orbscan ii tomography (bausch & lomb, rochester, ny) all clearly show keratoconus in the left eye (bottom row). Keratoconus is an uncommon corneal disorder where the central or paracentral cornea undergoes progressive thinning and steepening, causing irregular astigmatism. Corneal topography is an important tool for detecting corneal morphology, enabling both correct classification of keratoconus (kc) and detection of suspicious or initial patterns of the disease. This is a 26 year old male patient with keratoconus demonstrating a prominent fleischer ring around the base of the cone. other typical signs are also seen including vogt's striae in the center and stromal scarring at the apex from episodes of hydrops.
