The most common types of amyloidosis are localized AL, systemic AL (primary) include immunoglobulin light-chain amyloidosis (AL) due to an underlying monoclonal B-lymphocyte/plasma cell disorder, systemic AA (secondary) due to chronic inflammatory diseases, systemic wild-type ATTR and systemic hereditary ATTR are age-related or familial, respectively, and involve the deposition of transthyretin protein [2, 3]. Here, TTR is linked to axial length measurement.
