Trapdoor fractures are also known as “white-eyed blowout fractures (WEBOFs)” or “linear nondisplaced” fractures. They are most common in children and are defined by the lack of displacement of the bones involved. In children, bones are composed of a higher proportion of osteocytes than osteoblasts and thus a smaller amount of calcified osseous tissue, allowing them to be more pliant. In contrast, the less elastic nature of adult bone is more likely to result in comminuted fractures. Although much less common, trapdoor fractures can occur in adults. Trapdoor fracture has been documented in literature in a 37-year-old patient. We report a rare case of WEBOF of the floor of the orbit in an elderly female.
A 65-year-old female presented with blunt trauma to the right eye followed by pain on elevation. She denied a history of diplopia, nausea, or vomiting. Anteriorsegment examination was normal except for restriction of elevation in the right eye [Figure 1]a, [Figure 1]b, [Figure 1]c. Computed tomography scan revealed a linear undisplaced fracture line in the floor of the right orbit and impingement of the inferior rectus muscle [Figure 1]d. The patient was treated with oral steroids. On follow-up after 2 weeks, recovery of extraocular movements to near normal was observed.

This case highlights a rare presentation of WEBOF in an elderly patient. Oculocardiac reflex may be absent in adults. In patients with orbital trapdoor fractures, no apparent clinical or radiographic finding may be present apart from an abnormal ocular motility. WEBOF should be considered in cases of blunt trauma in elderly patients presenting with white eye and restricted extraocular movements. Conservative treatment with systemic steroids may be beneficial.
