Post-operative visual loss (POVL) is a known complication following spinal surgery. We would like to highlight few points regarding orbital emphysema which may cause diagnostic dilemma if neuroimaging evaluations are delayed following POVL. The dehisence of lamina papyracea is a known anatomical variation of ethmoid bone.[1] Sen and Chaturvedi[2] reported a case of spontaneous orbital emphysema (SOE) following sneezing. The final diagnosis is dehisence of lamina papyracea with orbital emphysema. SOE may cause orbital compartment syndrome (OCS), central retinal artery occlusion (CRAO) and ischemic optic neuropathy (ION). Orbital air absorption may take up to one week.[3] Occasionally in POVL, neuroimaging evaluation may be delayed up to one week.[4] Probably in this situation, SOE should be considered as differential diagnosis. SOE would have caused OCS. Air would have been absorbed prior to neuroimaging study. To conclude, in POVL due to OCS following spine surgery, SOE should be considered if there is delay in neuroimaging study of more than a week. Financial constraints may be responsible for delay in neuroimaging study.
