{Abstract}: To assess the utility of a marginal full thickness blepharotomy (MFTB) for the treatment of orbital compartment syndrome.<BR>An experimental study design employing a cadaver model for orbital compartment syndrome was used to assess the efficacy of an MFTB. Elevated orbital compartment pressures were created in 12 orbits of 6 fresh cadaver heads. Intraocular pressure, as an analog of orbital pressure, was measured before and after inferior and superior MFTBs were performed. Statistical analysis was performed on the collected data to assess the efficacy of the procedure.<BR>Both procedures were found to significantly lower the orbital compartment pressure. MFTB of the inferior lateral eyelid decreased orbital compartment pressure by an average of 62.2 mm Hg (95% CI, 56.9-67.5). MFTB of the superior lateral eyelid following MFTB of the inferior lateral eyelid decreased the orbital compartment pressure by an additional average of 10.3 mm Hg (total average reduction of 72.5 mm Hg; 95% CI, 68.1-76.9).<BR>Orbital compartment syndrome is a time-sensitive vision-threatening emergency that requires prompt diagnosis and intervention to prevent irreversible vision loss. The authors describe the MTFB, a simple one-step procedure that when performed correctly results in a significant decrease in orbital compartment pressure, making it a viable option when canthotomy and cantholysis fails or is unable to be performed.
