A recent article provides valuable insights into different aspects of astigmatism in the Duane Retraction Syndrome (DRS) subtypes. The differing underlying pathophysiology in type II DRS and its higher prevalence in the mentioned study, along with possible age variations among different DRS subtypes, complicates the interpretation of the results. The mechanical forces generated by the co-contraction of the horizontal rectus muscles in patients with Duane Retraction Syndrome (DRS) may contribute to changes in the shape of the cornea, potentially leading to astigmatism. However, the exact mechanism needs further scrutiny, considering all possible contributing factors.
