Creatine kinase elevation after scleral buckling.

A two- to three-fold elevation in serum creatine kinase levels were found in patients postoperatively after scleral buckling procedures. Further fractionation revealed the myocardial band (CK-MB) to be absent; with skeletal muscle (CK-MM) contributing to the enzyme elevation. Isoenzymes are recommended in postoperative patients when myocardial infarction is considered.
