Myiasis is infestation of the body by fly maggots. Immobile patients with skin wounds in exposed areas are at high risk of developing myiasis. We report a case of orbital myiasis from the species Chrysomya bezziana complicating squamous cell carcinoma of the eyelid. Magnetic resonance imaging of the orbit is useful for delineating the extent of the infestation and identifying residual maggots. In extensive orbital myiasis, exenteration is needed to prevent intracranial extension of tissue destruction.
