Most cases of strabismus have a chronic and stable or known etiologic diagnosis prior to surgery. In some cases, however, surgery is undertaken to correct a stable ocular misalignment without a definitive etiology. We present 2 cases, one with euthyroid Graves' orbitopathy and the other with amyloid light-chain amyloidosis, in which extraocular muscle biopsy performed intraoperatively allowed histopathologic confirmation of a clinical diagnosis.
