Compensatory versus non-compensatory types in myopic acute acquired comitant esotropia: a new classification based on fusion ability at the far point

Prolonged near gaze without MC is a critical risk factor for myopic AACE. Classifying patients based on fusion compensation at the FP reveals two distinct subtypes with different clinical profiles. The compensatory type likely represents an abnormal adaptation to excessive convergence demand, whereas the non-compensatory type may indicate a decompensated mechanism. This new classification provides valuable insights for etiology and management.
