Describe before classifying

A disciplined review begins with what is visible: symmetry, axis orientation, superior-inferior distribution, localization, magnitude, and inter-eye relationship. Descriptive language reduces the risk of forcing every atypical map into a diagnostic label.

Curvature patterns

Anterior curvature maps may show symmetric or asymmetric bow-tie configurations, inferior or superior steepening, skewed radial axes, or other localized patterns. Map scale, color step, centration, and display type can change visual appearance, so numerical and geometric confirmation matters.

Tomographic corroboration

Posterior elevation and pachymetric distribution can provide information not present in anterior curvature alone. A coherent ectatic pattern may involve spatially related abnormalities across curvature, elevation, and thickness progression; isolated discordant findings require quality and source review.

Laterality and time

Bilateral asymmetry can be informative, but one eye should not be used as a normalizing substitute for the other. Serial examinations can help distinguish stable anatomy from change only when acquisition conditions and image quality are sufficiently comparable.
