A frequent complication after limb amputation is the appearance of phantom limb syndrome, a phenomenon that has also been studied in the amputation of different body parts. Cases reported in relation to ophthalmologic surgery are few and evidence is limited in terms of specific management, which makes this a very important study. We report the case of a patient diagnosed with phantom eye syndrome in the post-operative period of an orbital exenteration surgery. A comprehensive approach was taken with multimodal symptom management, including intervention treatment. Significant improvement regarding the pain was achieved; however, non-painful ghost sensations persisted. Upon reviewing the available literature on the subject, its pathophysiology is not fully elucidated. Its incidence is highly variable, as well as the symptoms’ appearance. The presence of headache and eye pain prior to surgery seem to be risk factors. Climate and psychological stress are exacerbating factors of the symptomatology. No high-quality evidence was found in terms of management guidelines, with the use of antidepressants, anticonvulsants and opioids being the most recommended. Interventional management is an option according to the characteristics of the pain and associated symptoms.

Introduction: Administering systemic lidocaine has been shown to deliver effective analgesia for both cancer-related and non-cancer pain. Adverse effects and toxicity are rare with controlled administration. Objective: To report the results obtained after the indication to manage with IV lidocaine infusion to control neuropathic pain flares in 9 cancer patients. Methodology: Observational, descriptive, case series-type study. A search was conducted in the files of the Pain and Palliative Care Service of the National Cancer Institute - Instituto Nacional de Cancerología - in Bogotá. Patients over 18 years old diagnosed with cancer, who experienced high intensity neuropathic pain and with the cognitive ability to rate their pain in a numerical analogue scale (NAS), without any absolute contraindications for the use of IV lidocaine were included; patients were assessed between September 27 and November 21, 2019. Results: 9 patients experiencing a pain flare-up which was characterized as neuropathic were registered, of which 89 % had some improvement following the administration of an initial lidocaine bolus. After one hour, 60 % reported over 40% improvement in the initial NAS. After 24 hours all patients had experienced some improvement, with a reduction of 46% in the pain scale as compared to the baseline. Conclusions: In this series of cases, the intravenous infusion of lidocaine as an option for the management of neuropathic pain flares seems to reduce pain intensity following the initial bolus administration.
