Sutureless extraocular muscle biopsy technique

Purpose: To describe a simple and novel technique of obtaining an extraocular muscle (EOM) biopsy. Methods: Our sutureless method involves obtaining a full-thickness 3-mm EOM specimen using a disposable punch biopsy. results: The procedure was performed successfully, with no worsening of eye movement, muscle weakness, or cosmetic defects postoperatively. The acquired full-thickness specimen was sufficient for analysis. conclusions: This technique to obtain an EOM biopsy allows a straightforward sutureless method, providing an adequate sample for tissue scrutiny.
