Severe Orbital Myiasis Caused by Chrysomya Bezziana- A Case Report

An 88-year-old lady was brought to the hospital immediately after noticed by her neighbours that she was bleeding from her right eye. On examination, her right eye was pthisical with maggots’ infestation of her right orbit. Over a hundred live maggots were extracted using forceps. Computed Tomography scan revealed the infestation was confined to the right orbit. Patient underwent an exenteration of the right orbit under general anaesthesia. The species of the maggots were identified by entomologist as Chrysomya Bezziana, which is an aggressive living-tissue-eating-larvae. In this case report, it is concluded that orbital myiasis caused by Chrysomya Bezziana poses a very real risk of intracranial invasion as they feed on living tissues. Adjacent tissue destruction can be very rapid and definitive treatment involves urgent removal of its larvae via surgical debridement. To our knowledge, we are reporting the first case of orbital myiasis from a patient in Malaysia. Therefore, our case report may be helpful in the management of similar case of orbital myiasis.
