Topography In Clinical Practice — Corneal

: Use a rotating Scheimpflug camera to create a 3D model of the entire anterior segment, capturing both anterior and posterior surfaces as well as corneal thickness. 2. Standard Map Interpretation

: Use a series of concentric black and white rings (Placido discs) reflected off the tear film to map the anterior (front) corneal surface. Corneal Topography in Clinical Practice

Topographic devices generally fall into two categories based on their measurement principle: : Use a rotating Scheimpflug camera to create

Clinicians typically review four primary maps to screen for pathologies like keratoconus: Corneal topography in clinical practice - PubMed Corneal Topography in Clinical Practice
