Total orbital exenteration with temporalis muscle transfer and secondary healing.

OBJECTIVE: To evaluate the outcomes of orbital exenteration with temporalis muscle flap repair of the socket and secondary healing of the anterior surface of the flap in ocular, conjunctival, and eyelid malignancies. DESIGN: Retrospective single-centre study. PARTICIPANTS: Consecutive patients who underwent total exenteration for malignancy with temporal muscle flap repair of the socket between December 2009 and January 2016. METHODS: We report the outcomes of this surgical technique in terms of healing without fistula formation and time to epithelialization. RESULTS: Twenty-nine patients underwent surgery using this technique. Diagnoses consisted of 18 conjunctival melanomas, 2 choroidal melanomas, 6 squamous cell carcinomas, 2 sebaceous cell carcinomas, and 1 basal cell carcinoma. Mean age at surgery was 70.7 years and mean follow-up was 27.4 months. On histological analysis, tumour excision was complete in 25 patients, of whom 3 had an orbital recurrence after exenteration (3 conjunctival melanomas). Four patients had incomplete tumour excision, of whom 3 underwent postoperative orbital radiotherapy with no subsequent orbital recurrences. Complete epithelialization of the socket occurred in mean 7.9 weeks (range 2-16 weeks). Flap necrosis occurred in 1 patient after postoperative radiotherapy (with sino-nasal fistula formation); 2 other patients developed sino-orbital fistulas. CONCLUSION: After orbital exenteration, spontaneous epithelialization of the socket may take up to several months. Use of a temporalis muscle flap can reduce the duration of socket healing postoperatively, even if left to heal by secondary intention. This may facilitate early postoperative radiotherapy when indicated. Aesthetic results are acceptable and local surgical complications are rare.

The AflibeRcept use in rEal life study for the treatment of diabetiC macular oedema In the French overseas territories: A 12 months follow-up Study - The RECIF Study.

PURPOSE: The incidence and severity of diabetes is particularly high in the French overseas territories (FOT). The RECIF study evaluated real life management of diabetic macular oedema (DME) treated by aflibercept in FOT. METHODS: A prospective, noncomparative, multicentric, non-interventional, study that evaluated functional and anatomical results of patients treated by aflibercept. Twelve retina specialists working in French Polynesia, La Reunion, Guadeloupe and Martinique participated in the study. RESULTS: 67 eyes of 57 patients were followed for 12 months. Average VA gain was 7.8 ETDRS letters. 29.9% of eyes gained at least 15 letters, 6% lost 15 letters or more. 67.2% of eyes achieved visual acuity of 70 letters or better. Average central retinal thickness decrease was 115.3 µm. The mean number of injections during the 1st year of treatment was 4.9. 69% of eyes had a loading dose of at least three-monthly injections. 3 eyes were switched to steroid injections during the follow-up for lack of efficacy. CONCLUSION: This study confirmed the efficacy of intravitreal treatment of DME by aflibercept, in the French overseas territories. This evaluation of real-life management of DME underlines the importance of improvement of patient education and collaboration with referring physicians.

Orbital Leakage of Intraocular Silicone Oil: Case Reports and Literature Review.

Silicone oil migration into the periorbital tissues occurs rarely after vitreo-retinal surgery and two cases are reported. The first case was a 48-year-old woman who presented with a blind painful right eye, upper eyelid swelling, and ptosis after multiple vitreo-retinal surgeries. Diffuse infiltration of silicone oil in the upper eyelid and anterior orbit was found during evisceration, mainly around the plate of a Baerveldt glaucoma valve. In the second case, a 69-year-old man with prior right scleral rupture underwent silicone oil tamponade for retinal detachment and presented with right upper eyelid swelling due to multiple silicone oil granulomas within the orbit. Open globe injury and glaucoma drainage devices both appear to facilitate extraocular migration of silicone oil that results in marked orbital infiltration and inflammatory response.

Low retinal toxicity of intravitreal carboplatin associated with good retinal tumour control in transgenic murine retinoblastoma.

BACKGROUND: Retinoblastoma is a rare intraocular malignancy in children. Current treatments have many adverse effects. New therapeutic approaches like intravitreal injections of chemotherapies are currently being developed but their toxicities need to be evaluated on animal models. This study compares the efficacy and toxicity of intravitreal melphalan, topotecan and carboplatin, alone or in combination (sequential administration), in the LHBetaTag retinoblastoma mice. METHODS: Mice were divided into nine groups: control, carboplatin 1.5 and 4 µg, melphalan 0.1 and 1 µg, topotecan 0.1 and 1 µg, carboplatin 4 µg/topotecan 0.1 µg and melphalan 1 µg/topotecan 0.1 µg. The follow-up was performed using fundus imaging and optical coherence tomography combined with histopathological analysis. Absence of tumour and presence of calcified tumours were the criteria for therapeutic response assessment. Ocular complications were assessed after four weekly injections. Retinal toxicity was defined by the decrease of retinal thickness and of the number of retinal layers. RESULTS: Topotecan was inactive on retinal tumours. Melphalan (1 µg) led to a complete tumour control in 91.7% of eyes. Carboplatin strongly decreased the tumour burden (85.7-93.8% of eyes without retinal tumour). The intravitreal injection itself led to ocular complications (25% of media opacities and 45.7% of retinal detachment). Only melphalan at 1 µg showed a strong retinal toxicity. The two combinations showed a good efficacy in reducing the number of eyes with retinal tumours with a reduced retinal toxicity. CONCLUSIONS: This preclinical study suggests that intravitreal injection of carboplatin has a low toxicity and could be evaluated in clinical practice to treat patients suffering from retinoblastoma.

Evaluation of anxiety and pain in eyelid surgery patients: a pilot study.

OBJECTIVE: A high level of preoperative anxiety may have negative consequences on the medical and psychological outcomes of a surgical intervention. The present study aims to identify the factors associated with high preoperative anxiety in eyelid surgery patients and to determine whether there is a relationship between preoperative anxiety and the pain felt during and after the procedure. DESIGN: Prospective single-centre pilot study between December 2017 and April 2018. PARTICIPANTS: Consecutive patients undergoing elective eyelid surgery. METHODS: The Amsterdam Preoperative Anxiety and Information Scale and a numeric rating scale were used to evaluate preoperative anxiety and need for information as well as peroperative and postoperative pain. RESULTS: Thirty-two patients were included. Mean age at surgery was 65.8 years. Most patients underwent lateral canthoplasty (44%) or ptosis surgery (25%), and all had local anaesthesia. Thirty-eight percent of the patients had a high level of preoperative anxiety (i.e., unsuited to the situation of the surgical stress). Factors associated with higher levels of preoperative anxiety were female sex, age under 65 years, no previous oculoplastic surgery, and unilateral surgery. Patients who felt pain during and after the procedure were found to have had higher levels of preoperative anxiety than the patients who felt no pain. CONCLUSIONS: A high level of preoperative anxiety may increase the pain felt by the patient during and after the surgical procedure. It is therefore important to implement anxiolytic measures before an eyelid surgery is performed, especially in patients who have a risk of elevated preoperative anxiety.

A Case of Velocardiofacial Syndrome With Bilateral Inferior Punctum and Canalicular Agenesis.

A 16-year-old girl diagnosed with velocardiofacial syndrome complained of occasional bilateral ocular discharge. Examination revealed an agenesia of the inferior puncti and canaliculi, while the irrigation through the superior puncta was patent on both sides. Dacryocystorhinostomy with insertion of Lester Jones tubes is not considered for the time being because of the absence of epiphora. To the best of the authors' knowledge, this is the second reported case of lacrimal system agenesia in velocardiofacial syndrome.

Supporting better adherence among patients engaged in intermittent self-catherisation.

Coloplast has conducted a qualitative study among health professionals working in the field of continence care. Interviews with health professionals working in urology and rehabilitation provided insights into the barriers to, and supporters of, adherent behaviour-suggesting ways in which health professionals can work with patients performing intermittent self-catheterisation (ISC) to support better adherence. This includes individualised training that addresses individual fears, ensures correct understanding of the body and the treatment, and eliminates misconceptions. They can also help patients set realistic ambitions, and give them practical advice that will help them adapt ISC to their daily life. Patients need to know how to handle urinary tract infections, how to cope with contradictory instructions from other sources, and how to identify support resources and accurate information. Specific challenges relating to support for urology patients and rehabilitation patients were also highlighted.

TREATMENT OF EXUDATIVE CIRCUMSCRIBED CHOROIDAL HEMANGIOMA: Efficacy of Fractionated Proton Therapy (20 Gray Relative Biological Effectiveness in 8 Fractions).

PURPOSE: To evaluate treatment of circumscribed choroidal hemangioma by hyperfractionated proton beam therapy protocol (20 gray relative biological effectiveness in 8 fractions) on tumor control, attachment of retina and visual function. METHODS: Retrospective review of patients treated between January 2010 and April 2015 with at least 6 months of follow-up. RESULTS: Forty-three patients with exudative and symptomatic circumscribed choroidal hemangioma were included. Before treatment, 41 (95%) presented an exudative retinal detachment, median visual acuity was 20/63 and median tumor thickness was 3.3 mm. Mean follow-up was 26 months (7-62). At last follow-up, all patients presented regression of ultrasound tumor thickness and 23/43 (53.5%) a totally flat scar. The mean time to achieve a flat scar was 20 months. Retina was reattached in all patients except one with 9 months of follow-up. Visual acuity was improved or stabilized in 37 patients (86%) and final median visual acuity was 20/25. No patient presented radiation maculopathy or papillopathy. CONCLUSION: Proton beam therapy with a dose of 20 gray relative biological effectiveness delivered in 8 fractions provides excellent anatomical and functional results and are comparable with those obtained with the same dose delivered in 4 fractions. Longer follow-up is required to determine the long-term radiation sequelae.

Malignant Transformation of a Multi-Operated Divided Nevus of the Eyelids.

A woman in her early fifties had regular follow-up for a medium-sized divided nevus of the eyelids which had undergone several surgical excisions during childhood for functional and esthetic reasons. Malignant transformation of the nevus occurred in the inferior eyelid, with the appearance of a new pigmented flat lesion. Histology showed in situ melanoma, and an NRAS activating mutation was found. A full-thickness excision of the inferior eyelid was performed, followed by reconstruction. Local recurrence of the melanoma occurred 1 year after surgery. Lifelong follow-up of divided nevi of the eyelids is recommended, even if very few cases of malignant transformation have been reported so far.

Colon cancer and IgG4-related disease with orbital inflammation and bilateral optic perineuritis: A case report.

RATIONALE: Immunoglobulin G4-related disease (IgG4-RD) is an inflammatory condition of unknown cause. Cancer might be related to the development of certain IgG4-RD but to date, little literature documents it. PATIENT CONCERNS: A 78-year old man presented with unilateral proptosis responsive to steroids, initially attributed to nonspecific orbital inflammation. DIAGNOSIS: Right hemicolectomy was performed because of a suspicious lesion which turned out to be tubulovillous adenoma on histological analysis. Eight months after the surgery, a mass infiltrating the mesentery was found and biopsy revealed IgG4-RD. INTERVENTIONS: Both the orbital inflammation and abdominal mass infiltrating the mesentery were responsive to steroids and rituximab administered to treat IgG4-RD. OUTCOMES: In the course of IgG4-RD, the patient developed bilateral optic perineuritis, causing bilateral visual loss. Colon cancer with synchronous multiple liver metastases was found 1 year after rituximab treatment. LESSONS: This case raises the possibility of IgG4-RD being a paraneoplastic syndrome in some patients. Cancer screening should probably be performed in some elderly patients diagnosed with IgG4-RD.

Iterative Variance Stabilizing Transformation Denoising of Spectral Domain Optical Coherence Tomography Images Applied to Retinoblastoma.

BACKGROUND: Due to the presence of speckle Poisson noise, the interpretation of spectral domain-optical coherence tomography (SD-OCT) images frequently requires the use of data averaging to improve the signal-to-noise ratio. This implies long acquisition times and requires patient sedation in some cases. Iterative variance stabilizing transformation (VST) is a possible approach by which to remove speckle Poisson noise on single images. METHODS: We used SD-OCT images of human and murine (LH Beta-Tag mouse model) retinas with and without retinoblastoma acquired with 2 different imaging devices (Bioptigen and Micron IV). These images were processed using a denoising workflow implemented in Matlab. RESULTS: We demonstrated the presence of speckle Poisson noise, which can be removed by a VST-based approach. This approach is robust as it works in all used imaging devices and in both human and mouse retinas, independently of the tumor status. The implemented algorithm is freely available from the authors on demand. CONCLUSIONS: On a single denoised image, the proposed method provides results similar to those expected from the SD-OCT averaging. Because of the friendly user interface, it can be easily used by clinicians and researchers in ophthalmology.
