Aim Phantom eye syndrome is a poorly understood and underestimated complication of eye removal (ER). Seeing with the amputated eye, referred to as phantom vision (PV), is undoubtedly the most intriguing and confusing complication experienced by anophthalmic patients. The aim of the study was to assess PV prevalence, clinical features and risk factors after ER. Methods A multicentric questionnaire-based study was conducted between April 2016 and July 2017. Patients >18 years who underwent ER >3 months ago had a socket examination before inclusion. Data recorded included patients' demographics, and preoperative, surgical and postoperative features. Results One hundred patients (53 men) with a mean age of 65.1 years (29-92; SD=13.0) were included. ER indications were: uveal melanoma (n=24, 24%), trauma (n=20, 20%), retinal detachment (n=20, 20%), glaucoma (n=14, 14%) and endophthalmitis (n=12, 12%). Thirty (30%) patients experienced PV. Elementary and complex visual hallucinations were experienced by 80% and 20% of patients, respectively. PV usually appeared within the first postoperative month and tended to decrease over time. Risk factors for PV were the preoperative use of proton beam therapy (p=0.006), uveal melanoma (p=0.014), enucleation (p=0.015), anxiety with a Hospital and Anxiety Depression (HAD) score >8 (p=0.042), depression with a HAD score >8 (p=0.030), phantom eye pain (p=0.044) and phantom eye sensations (p=0.002). Conclusion PV was reported by one-third of our patients. Despite being widely misunderstood, ophthalmologists and neurologists should be aware of this complication to adequately reassure patients.

To assess the usefulness of FDG-PET/CT as a potential diagnostic tool for detecting underlying systemic diseases (SD) in patients with orbital inflammatory disorders (OID). All consecutive patients managed for new-onset OID between 2011 and 2018 in a tertiary referral center, who underwent FDG-PET/CT as part of the etiological diagnostic workup were evaluated. To quantify the incremental value of FDG-PET/CT over standard diagnostic workup, the Net Reclassification Index (NRI) and Integrated Discrimination Index (IDI) were used. Among the 22 patients enrolled, 11 (50%) had a positive FDG-PET/CT. After clinicobiological evaluation, FDG-PET/CT correctly reclassified 4(29%) of 14 patients with SD (p =.04) and 1(13%) of 8 with idiopathic orbital inflammation syndrome (p =.32). NRI and IDI were 0.41 ± 0.17 (p =.03) and 0.38 ± 0.08 (p <.001), respectively. FDG-PET/CT successfully detected asymptomatic lesions in all (n = 4) patients with lymphoma. FDG-PET/CT enabled accurate reclassification of more than one-quarter of patients with SD, especially extraorbital lymphomas. [ABSTRACT FROM AUTHOR]

Purpose: Phantom eye syndrome (PES) is an underestimated complication of eye amputation (EA) characterized by phantom eye pain (PEP), phantom visions and/or phantom sensations. The aim of this study was to assess PEP prevalence, features, risk factors, social and psychological consequences and associated quality of life. Methods: A questionnaire study was conducted in three oculoplastic departments between April 2016 and July 2017. Patients >18 years who had undergone EA ≥3 months earlier were included and asked to complete a prestamped questionnaire. Patient's characteristics, preoperative, surgical and postoperative data were collected. Results: Of the 185 questionnaires given, 115 (62%) were returned for analysis. Hundred patients with a mean age of 65.1 years (29–92; SD = 13.0) were included. Eye amputation (EA) indications were uveal melanoma (n = 24, 24%), trauma (n = 20, 20%), retinal detachment (n = 20, 20%), glaucoma (n = 14, 14%) and endophthalmitis (n = 12, 12%). Forty‐seven (47%), 30 (30%) and 38 (38%) patients experienced PEP, phantom visions and phantom sensations, respectively. Anxiety and depression [Hospital Anxiety Depression scale (HADS) score ≥8 for both] were diagnosed in 34 (34%) and 42 (42%) patients, respectively. The mean EQ‐5D‐3L and EQ‐5D visual analogue scale scores were 0.8 (0.06–1; SD = 0.2) and 68 (0–100; SD = 22), respectively. Preoperative eye pain (p = 0.031), glaucoma (p = 0.027), postoperative anxiety with HADS score ≥8 (p = 0.012) and ≥11 (p = 0.014), aesthetic discomfort (p = 0.002) and EQ‐5D‐3L score <0.8 (p < 0.001) were significantly associated with PEP in the univariate analysis. In the multivariate analysis, only anxiety (HADS score ≥8) was significantly associated with PEP (p = 0.009). Conclusion: Phantom eye pain (PEP) is a common complication of EA strongly associated with postoperative anxiety. [ABSTRACT FROM AUTHOR]

Adenoid cystic carcinoma (ACC) is the most common malignant epithelial cancer of the lacrimal gland. Despite a slow rate of growth, ACCs are ultimately associated with poor clinical outcome. Given the rarity of this disease, most recommendations regarding therapy are guided by expert opinion and retrospective data rather than level 1 evidence. Surgery and postoperative radiation therapy are commonly used as initial local treatment. In patients at high risk of recurrence, concomitant platinum-based chemotherapy may be added to postoperative radiotherapy in an attempt to enhance radio-sensitivity. While encouraging responses have been reported with intra-arterial neoadjuvant chemotherapy, this strategy is associated with substantial toxicity and should be considered investigational. For patients with metastatic disease not amenable to surgery or radiotherapy, chemotherapy may have a role based on its modest efficacy in non-lacrimal ACC. Similarly, molecular targeted agents may have a role, although the agents tested to date in non-lacrimal ACC have been disappointing. A better understanding of the biology of ACC will be crucial to the future success of developing targeted agents for this disease. [ABSTRACT FROM AUTHOR]

Purpose: To better characterise the effects of corticosteroids on the course of pure idiopathic orbital inflammation syndrome (pIOIS)., Methods: This was a national, multicentre, prospective, non-interventional cohort study ( SIOI ). Among the 35 patients with histologically proven orbital inflammation who had previously been studied for their IgG4 immunostaining status, we selected those with a negative IgG4 status (ie, pIOIS) who received corticosteroids as single first-line treatment. Clinical, morphological and pathological findings at diagnosis and during follow-up from treatment initiation to study completion were analysed. Patients were assessed for their response to prednisone after the 24-month prospective phase in terms of remission (≤10 mg/d) or failure (>10 mg/d). Daily standard doses of prednisone (DSDP) were calculated at different time-points and compared between response groups., Results: Of the 17 patients with pIOIS included in the final analysis, two-thirds received corticosteroids only. DSDP (mg/kg-day) were significantly higher at the time of failure in eight patients (47%) than in nine (53%) remitting at M24 (0.16 vs 0.045; p: 0.03). Notably, patients with pIOIS with a cellular pattern or orbital fat involvement tended to receive higher daily corticosteroid doses in the event of failure than remission (0.16 vs 0.045 and 0.12 vs 0.042, respectively). During treatment, maximal DSDP was 0.52 in failed patients., Conclusion: The highest corticosteroid doses were insufficient to prevent failure in patients with pIOIS, particularly in those with a cellular pattern or orbital fat involvement. Large-scale interventional studies are now necessary to clarify prognostic factors and optimise corticosteroid management in patients with pIOIS., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2024.

Botulinum neurotoxins are the most popular non-surgical treatments for aesthetic indications, but there is uncertainty about whether certain formulations are comparable in efficacy and safety and can be substituted for one another by a simple one to one dose conversion ratio. An expert panel of French practitioners was convened to establish a consensus on the clinical equivalence in efficacy and safety of OnabotulinumtoxinA (900 KDa) and IncobotulinumtoxinA (neurotoxin free from complexing proteins - 150 KDa). The consensus was divided into three sections incorporating a biological, bibliographic and clinical analysis of the two toxins. This included a review of the published data that have directly compared the two toxins for aesthetic indications and a survey of the panel's extensive clinical experience with the two toxins in terms of efficacy and safety. All panel members reviewed and endorsed the content of each section. Among this expert panel of French aesthetic physicians and biologists there was consensus that OnabotulinumtoxinA and IncobotulinumtoxinA are clinically equivalent in terms of efficacy and safety, and that a switch from one drug to the other can be made using a simple 1:1 conversion ratio.
