title: Superior orbital 'petrositis' and late ischaemic monocular blindness induced by intense UV radiation exposure.
abstract: Many physical agents cause neuropathies. The most common are chronic pressure, vibration and temperature. In general, these lesions occur at work, as a result of accidents or through chronic exposure to the physical agent. Radiation leading to peripheral neuropathy is also related to radiotherapy in cancer treatment, as an undesirable side-effect. We present here a case report of short, intense UV radiation exposure at work, leading to delayed-onset ocular neuropathy. A clear cause-effect relationship is shown, demonstrated using magnetic resonance imaging scans. We suggest that the mechanism was thermal and ischaemic.
