[Contribution of technological aids to the extraction of orbital foreign bodies]. J Fr Ophtalmol 2024; 47:104190. [PMID: 38669863 DOI: 10.1016/j.jfo.2024.104190] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/14/2024] [Accepted: 02/17/2024] [Indexed: 04/28/2024]
Abstract
BACKGROUND Removal of orbital foreign bodies is a surgical challenge. The purpose of this study is to report our experience in the removal of orbital foreign bodies and to evaluate the usefulness of various technological aids in their removal. MATERIALS AND METHODS We conducted a single-center retrospective study at Nice University Hospital (France) from January 2017 to December 2023. All patients undergoing surgery for an orbital foreign body during the study period were included. Data recorded included the nature of the orbital foreign body, its size, location, surgical route, outcome (success, partial success, failure), and technological aids used (intraoperative navigation, intraoperative imaging scope, orbital magnet). Concurrently, we designed a dedicated orbital magnet, which was tested in the anatomy laboratory and in two of our patients. RESULTS Six patients, all young men, were included during the study period. Removal was successful, partially successful, or unsuccessful in one-third of cases, respectively. Failure was associated with orbital foreign bodies located in the intraconal or posterior orbital space. Preoperatively, the use of a "low-artifact" scanner allowed us to better determine the exact size and shape of the orbital foreign body. Intraoperative navigation was not accurate enough, due to the mobility of the orbital bodies within the orbital fat. In our experience, intraoperative scope imaging was more accurate. The use of a dedicated orbital magnet was successfully tested in the anatomy laboratory and allowed the removal of a small orbital foreign body in one of our patients. Intraoperative surgical videos are provided. CONCLUSION Vegetal orbital foreign bodies must be systematically removed. Removal of non-vegetal orbital foreign bodies should be considered on a case-by-case basis based on their size, best assessed using a "low artifact" scanner, their location, and their intrinsic ferromagnetism. Intraoperative navigation does not appear useful, while intraoperative scope imaging does. A dedicated orbital magnet might be helpful in removing ferromagnetic orbital foreign bodies. However, an orbital magnet may be ineffective in removing intraorbital bullets, since they are made primarily of an alloy of copper and lead.

Is topical antibiotic use necessary to prevent surgical site infection following oculoplastic surgery? Graefes Arch Clin Exp Ophthalmol 2024:10.1007/s00417-024-06489-8. [PMID: 38643423 DOI: 10.1007/s00417-024-06489-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/29/2023] [Revised: 04/01/2024] [Accepted: 04/09/2024] [Indexed: 04/22/2024] Open
Abstract
PURPOSE To assess whether oculoplastic surgeries can be performed without any topical and systemic antibiotics, in a "100% antibiotic free" fashion. METHOD We conducted a multicenter retrospective study between November 2017 and December 2022. Patients who underwent an oculoplastic procedure were screened. Patients who received preoperative or postoperative systemic antibiotics were excluded. Intraoperative IV antibiotics were allowed. Patients were divided into two groups: those who were treated with local antibiotics ointments (LATB group) and those who were treated without local antibiotics ointments (LATB free group) postoperatively. The primary outcome was the incidence of surgical site infections (SSI). The relationship between the use of local antibiotics and the occurrence of SSI was assessed using Fisher's exact test. The alpha risk was set to 5% and two-tailed tests were used. RESULTS Among the 947 procedures included, 617 were included in the LATB group and 330 in the LATB free group. 853 and 80 procedures were classified Altemeier class 1 (clean) and class 2 (clean-contaminated) surgeries, respectively. Overall, 310 (32.73%) procedures were performed without any systemic nor topical antibiotics (100% antibiotic free fashion). SSI occured in four (4/617; 0.65%) and five (5/330; 1.52%) procedures in the LATB and LATB free group respectively, without any statistical difference between the groups (p = 0.290). A subgroup analysis was carried out by excluding the procedures performed under prophylactic intraoperative intravenous antibiotics and did not reveal any statistical difference between the two groups (p = 0.144). All SSI patients were treated with systemic antibiotics with favorable outcomes. Postoperative wound dehiscence was the only risk factor associated with postoperative SSI (p = 0.002). CONCLUSION This study suggests that performing a "100% antibiotic free" oculoplastic surgery without systemic and topical antibiotics is reasonable in Altemeier class 1 and class 2 procedures.

Clinical features, diagnosis, treatment, and course of ocular sarcoidosis with or without uveitis: A retrospective, comparative study. J Fr Ophtalmol 2024; 47:104153. [PMID: 38696861 DOI: 10.1016/j.jfo.2024.104153] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/21/2023] [Revised: 10/26/2023] [Accepted: 12/12/2023] [Indexed: 05/04/2024]
Abstract
OBJECTIVE To evaluate and compare characteristics, diagnosis, treatment, visual prognosis, and course between ocular sarcoidosis with or without uveitis in a population in Southern France. METHODS We retrospectively analyzed data from patients with ocular sarcoidosis in a tertiary eye care center in Nice from January 2003 to December 2021. The inclusion criterion was biopsy-proven ocular sarcoidosis according to IWOS criteria as the first clinical manifestation of sarcoidosis. RESULTS A total of 25 patients were included. Twenty patients had uveitis (70% panuveitis, 20% intermediate uveitis, and 10% anterior uveitis) and five patients had non-uveitic ocular sarcoidosis (one patient with dacryoadenitis, one patient with orbital granuloma, two patients with palpebral granuloma, and one patient with episcleritis). Only the cases with uveitis had bilateral involvement (85% of cases). There was no significant difference in ethnicity, biopsy diagnosis, systemic manifestations, or treatment between the two groups. Final visual outcomes remained good for both groups, with 96% of patients with BCVA>20/50, with no significant difference. Patients with non-uveitic sarcoidosis experienced less recurrence on treatment (P=0.042) and more remission (P=0.038) than patients with uveitis. Eighty percent of patients with uveitis had at least three suggestive clinical intraocular signs meeting IWOS criteria. CONCLUSION In this population in Southern France, uveitis was the most common presentation of ocular sarcoidosis. The type of ocular sarcoidosis does not appear to be correlated with the type of systemic manifestations, use of systemic therapy, or visual prognosis, but patients with non-uveitic ocular sarcoidosis appear to have a better course with fewer recurrences on treatment and more remission than patients with uveitic ocular sarcoidosis.

[Blue light and intraocular lenses (IOLs): Beliefs and realities]. J Fr Ophtalmol 2024; 47:104043. [PMID: 38241770 DOI: 10.1016/j.jfo.2023.104043] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/26/2023] [Revised: 10/18/2023] [Accepted: 10/22/2023] [Indexed: 01/21/2024]
Abstract
The first intraocular lenses (IOLs) used for cataract surgery transmitted both ultraviolet (UV) radiation and visible light to the retina. Colorless UV-blocking IOLs were introduced and rapidly adopted in the 1980s. Yellow-tinted blue-blocking (also known as blue-filtering) IOLs were marketed in the early 1990s. Blue-blocking IOLs were intended to simulate age-related crystalline lens yellowing to reduce the cyanopsia that some patients experienced after cataract surgery. When blue-filtering IOLs were introduced in North America, however, blue-blocking chromophores were advocated as a way to protect patients from age-related macular degeneration (AMD) despite the lack of evidence that normal environmental light exposure causes AMD. The "blue light hazard" is a term that describes the experimental finding that acute, abnormally intense light exposures are potentially more phototoxic to the retina when short rather than long wavelengths are used. Thus, in brief exposures to intense light sources such as welding arcs, ultraviolet radiation is more hazardous than blue light, which is more hazardous than longer wavelength green or red light. International commissions have cautioned that the blue light hazard does not apply to normal indoor or outdoor light exposures. Nonetheless, the hazard is used for commercial purposes to suggest misleadingly that ambient environmental light can cause acute retinal phototoxicity and increase the risk of AMD. Very large epidemiological studies show that blue-blocking IOLs do not reduce the risk or progression of AMD. Additionally, blue-filtering IOLs or spectacles cannot decrease glare disability, because they decrease image and glare illuminance in the same proportion. Blue light is essential for older adults' scotopic photoreception needed to reduce the risk of nighttime falling and related injuries. It is also critical for circadian photoreception that is essential for good health, sleep and cognitive performance. Unfortunately, age-related pupillary miosis, retinal rod and ganglion cell photoreceptor degeneration and decreased outdoor activity all reduce the amount of healthful blue light available to older adults. Blue-restricting IOLs further reduce the available blue light at a time when older adults need it most. Patients and ophthalmologists are exposed to hypothesis-based advertisements for blue-filtering optical devices that suppress short wavelength light critical for vision in dim lighting and for good physical and mental health. Spectacle and intraocular lens selections should be based on scientific fact, not conjecture. Ideal IOLs should improve photoreception rather than limit it permanently. Practice efficiency, surgical convenience and physician-manufacturer relationships may eliminate a patient's opportunity to choose between colorless blue-transmitting IOLs and yellow-tinted, blue-restricting IOLs. Cataract surgeons ultimately determine whether their patients have the opportunity to make an informed choice about their future photoreception.

Can 18F-FDG PET/CT findings be used to predict orbital tumor histology? J Fr Ophtalmol 2024; 47:103958. [PMID: 37758546 DOI: 10.1016/j.jfo.2023.04.011] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/11/2023] [Revised: 04/11/2023] [Accepted: 04/12/2023] [Indexed: 09/29/2023]
Abstract
PURPOSE To investigate whether 18F-FDG PET/CT might be useful to predict the histology of various orbital tumors based on the maximum standard uptake value (SUVmax) and the OMSUV (orbital max SUV)/MLSUV (mean liver SUV) ratio. PATIENTS AND METHODS A retrospective single-center study was conducted between May 2019 and December 2020. Patients with an orbital mass who underwent preoperative 18F-FDG PET/CT followed by an orbital biopsy were included. Tumor histology was classified as follows: orbital inflammation, solid tumor, low-grade lymphoid tumor, and high-grade lymphoid tumor. Orbital tumors were also classified as indolent or aggressive. Data recorded included the orbital SUVmax, OMSUV/MLSUV ratio and additional extra-orbital SUV sites. RESULTS Forty-five patients (24 men) were included. There were 15 (33.3%), 14 (31.1%), 9 (20%), and 7 (15.5%) cases of orbital inflammation, solid tumor, low-grade lymphoid tumor, and high-grade lymphoid tumor, respectively. No correlation was found between the OMSUV/MLSUV ratio and orbital SUVmax and tumor histology (Z = -0.77, Z = -0.6, Z = -1.6, and Z = 0.94, all P > 0.05, respectively). No correlation was found between the OMSUV/MLSUV ratio (Z = -1.42, P > 0.05) and orbital SUVmax (Z = -0.82, P > 0.05) and tumor aggressiveness (indolent versus aggressive). Subgroup analyses showed that SUVmax was predictive of lymphoma aggressiveness (P = 0.05) and was able to distinguish orbital cancers (all lymphomas+solid tumors) from benign tumors (P = 0.02). CONCLUSION 18F-FDG PET/CT could not be used to predict the underlying orbital tumor histology. However, more aggressive tumors, especially high-grade lymphomas and cancers, tended to have a higher orbital SUVmax compared to indolent lesions.

Intraoperative iStent versus postoperative selective laser trabeculoplasty in early glaucoma patients undergoing cataract surgery: A retrospective comparative study. J Fr Ophtalmol 2024; 47:103956. [PMID: 37783587 DOI: 10.1016/j.jfo.2023.03.042] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/15/2023] [Revised: 03/22/2023] [Accepted: 03/23/2023] [Indexed: 10/04/2023]
Abstract
PURPOSE To compare the efficacy and safety of iStent inject® versus 360° selective laser trabeculoplasty (SLT) in patients with early glaucoma undergoing cataract surgery. METHODS A retrospective non-randomized study was conducted in 73 eyes divided into two groups: cataract surgery+intraoperative iStent (n=40) versus cataract surgery+postoperative SLT at one month (n=33). The primary endpoint was intraocular pressure (IOP) lowering≥20% between baseline and 6 months postoperatively. The secondary endpoints were IOP lowering at 1, 6 and 12 months, and the mean number of IOP-lowering medications at 6 and 12 months. RESULTS The mean baseline IOP was 19.1 mmHg with no significant difference between groups. The mean baseline number of IOP-lowering medications was higher in the iStent group (n=1.95) compared to the SLT group (n=1.53; P=0.04). At 6 months, 18 (60%) patients in the SLT group and 20 (51%) patients in the iStent group achieved IOP lowering≥20% with no significant difference between groups (P=0.431). At 6 months, no difference in the mean number of IOP-lowering medications was found between groups (-0.92 and -0.89 in the iStent and SLT groups, respectively). Similar results were found at 12 months. CONCLUSION These results suggest similar safety and efficacy of intraoperative iStent and postoperative 360° SLT in lowering IOP and reducing glaucoma eye drops in early glaucoma patients undergoing cataract surgery. Treatment choice should be based on the ophthalmologist's experience and on the cost-benefit ratio.

LKB1-SIK2 loss drives uveal melanoma proliferation and hypersensitivity to SLC8A1 and ROS inhibition. EMBO Mol Med 2023; 15:e17719. [PMID: 37966164 PMCID: PMC10701601 DOI: 10.15252/emmm.202317719] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/17/2023] [Revised: 10/16/2023] [Accepted: 10/23/2023] [Indexed: 11/16/2023] Open
Abstract
Metastatic uveal melanomas are highly resistant to all existing treatments. To address this critical issue, we performed a kinome-wide CRISPR-Cas9 knockout screen, which revealed the LKB1-SIK2 module in restraining uveal melanoma tumorigenesis. Functionally, LKB1 loss enhances proliferation and survival through SIK2 inhibition and upregulation of the sodium/calcium (Na+ /Ca2+ ) exchanger SLC8A1. This signaling cascade promotes increased levels of intracellular calcium and mitochondrial reactive oxygen species, two hallmarks of cancer. We further demonstrate that combination of an SLC8A1 inhibitor and a mitochondria-targeted antioxidant promotes enhanced cell death efficacy in LKB1- and SIK2-negative uveal melanoma cells compared to control cells. Our study also identified an LKB1-loss gene signature for the survival prognostic of patients with uveal melanoma that may be also predictive of response to the therapy combination. Our data thus identify not only metabolic vulnerabilities but also new prognostic markers, thereby providing a therapeutic strategy for particular subtypes of metastatic uveal melanoma.

Characterisation of the protein expression of the emerging immunotherapy targets VISTA, LAG-3 and PRAME in primary uveal melanoma: insights from a southern French patient cohort. Pathology 2023; 55:929-944. [PMID: 37863710 DOI: 10.1016/j.pathol.2023.08.003] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/28/2023] [Revised: 07/02/2023] [Accepted: 08/04/2023] [Indexed: 10/22/2023]
Abstract
Uveal melanoma (UM) is the most common intraocular tumour in adults, with dismal prognosis once metastases develop, since therapeutic options for the metastatic disease are ineffective. Over the past decade, novel cancer therapies based on immunotherapy have changed the landscape of treatment of different forms of cancer leading to many hopes of improvement in patient overall survival (OS). VISTA, LAG-3 and PRAME are novel promising targets of immunotherapy that have recently gained attention in different solid tumours, but whose relevance in UM remained to be comprehensively evaluated until now. Here, we studied the protein expression of VISTA, LAG-3 and PRAME using immunohistochemistry in representative whole tissue sections from primary UM cases in a cohort of 30 patients from a single centre (Nice University Hospital, Nice, France). The expression of each of these markers was correlated with different clinical and pathological parameters, including onset of metastases and OS. We demonstrated the protein expression of VISTA and LAG-3 in small lymphocytes infiltrating the tumour, while no expression of the proteins was detected in UM cells. For PRAME, nuclear expression was observed in UM cells, but no expression in tumour infiltrating immune cells was identified. Increased levels of VISTA expression in tumour infiltrating lymphocytes (TILs) were associated with nuclear BAP1 expression and better prognosis. Higher levels of LAG-3 in TILs were associated with higher levels of CD8-positive TILs. PRAME nuclear positivity in melanoma cells was associated with epithelioid cell dominant (>90%) UM histological subtype, higher mitotic numbers and a higher percentage of chromosome 8q gain. This study proposes VISTA as a novel relevant immune checkpoint molecule in primary UM and contributes to confirm LAG-3 and PRAME as potentially important immunotherapy targets in the treatment of UM patients, helping to expand the number of immunotherapy candidate molecules that are relevant to modulate in this aggressive cancer.

Abstract
These guidelines are a consensus of French glaucoma and retina experts on the management of ocular hypertension (OHT) observed in a third of the cases after corticosteroid implant intravitreal injections. They update the first guidelines published in 2017. Two implants are marketed in France: the dexamethasone implant (DEXi) and the fluocinolone acetonide implant (FAci). It is essential to assess the pressure status before injecting a patient with a corticosteroid implant. A molecule-specific monitoring of the intraocular pressure is needed throughout the follow-up and at the time of reinjections. Real-life studies have allowed optimizing the management algorithm by significantly increasing the safety of these implants. Corticosteroid testing with DEXi should be performed before switching to FAci to optimize pressure tolerance of FAci. Beyond topical hypotensive treatments, selective laser trabeculoplasty may be considered in the therapeutic arsenal for the management of steroid-induced OHT and subsequent injections.

Abstract
PURPOSE To compare the effect of antiseptics and antibiotics on the occurrence of Infectious Keratitis (IK) secondary to Corneal Foreign Body (CFB) removal. METHODS Multicenter retrospective study conducted between June 2020 and June 2022 in patients referred for CFBs and treated with Picloxydine (Group 1) or Tobramycin (Group 2) for 7 days. A follow-up visit was scheduled on Day 3 (D3) and a phone call on D30. The primary outcome measure was the occurrence of IK. RESULTS 307 patients (300 men) with a mean age of 42.8 (14.8) years were included. The mean (SD) time to consultation was 43.1 (45.6) hours. Picloxydine and Tobramycin were given to 155 and 152 patients. Half of patients (n = 154, 50.2%) were building workers and 209 (68.1%) did not wear eye protections. CFBs were mainly metallic (n = 292, 95.1%). Upon referral, rust was found in 220 patients (72.1%). A burr was used in 119 (38.9%) patients. IK occurred in 15 (4.9%) patients, 8 (5.3%) in Group 1 and 7 (4.5%) in Group 2 (p = 0.797). IK was successfully treated in all cases. Persistent rust was found in 113 patients (36.9%) on D3 without difference between burr or needle use (p = 0.278). On D3, corneal healing was delayed in 154 patients (47.2%), mainly in burr-treated patients (p = 0.003). The mean (SD) work stoppage duration was 0.32 (0.98) days. CONCLUSION IK rate was 4.9%. The efficacy of antibiotics and antiseptics was similar on CFB removal. Using a burr was associated with a longer healing time. CFBs had a limited social impact.

Abstract
These are the recommendations of French glaucoma and retina experts on the management of ocular hypertension (OHT) observed in 1/3 of cases after intravitreal steroid implant injections. They are an update to the recommendations first published in 2017. There are two implants on the French market: the dexamethasone (DEXi) and fluocinolone acetonide (FAci) implants. It is important to know the pressure status before injecting a patient with a steroid implant. Monitoring of the IOP adapted to the specific drug is necessary throughout follow-up and reinjections. Real-life studies have made it possible to optimize the management algorithm by significantly increasing the safety of use of these implants. A corticosteroid test with DEXi is necessary before switching to FAci to optimize the pressure tolerance of the latter. In addition to topical glaucoma medications, SLT laser can be considered in the therapeutic arsenal for the management of steroid-induced OHT and future injections.

Assessment of Different Circulating Tumor Cell Platforms for Uveal Melanoma: Potential Impact for Future Routine Clinical Practice. Int J Mol Sci 2023; 24:11075.

Abstract
Liquid biopsy and circulating tumor cell (CTC) screening has gained interest over the last two decades for detecting almost all solid malignancies. To date, the major limitation in terms of the applicability of CTC screening in daily clinical practice is the lack of reproducibility due to the high number of platforms available that use various technologies (e.g., label-dependent versus label-free detection). Only a few studies have compared different CTC platforms. The aim of this study was to compare the efficiency of four commercially available CTC platforms (Vortex (VTX-1), ClearCell FX, ISET, and Cellsearch) for the detection and identification of uveal melanoma cells (OMM 2.3 cell line). Tumor cells were seeded in RPMI medium and venous blood from healthy donors, and then processed similarly using these four platforms. Melan-A immunochemistry was performed to identify tumor cells, except when the Cellsearch device was used (automated identification). The mean overall recovery rates (with mean recovered cells) were 39.2% (19.92), 22.2% (11.31), 8.9% (4.85), and 1.1% (0.20) for the ISET, Vortex (VTX-1), ClearCell FX, and CellSearch platforms, respectively. Although paramount, the recovery rate is not sufficient to assess a CTC platform. Other parameters, such as the purpose for using a platform (diagnosis, genetics, drug sensitivity, or patient-derived xenograft models), reproducibility, purity, user-friendliness, cost-effectiveness, and ergonomics, should also be considered before they can be used in daily clinical practice and are discussed in this article.

Abstract
INTRODUCTION Central vision loss due to diabetic macular edema (DME) is related to the macular edema itself, but also in some cases to alterations of the foveal avascular zone (FAZ). The aim of this trial was to study changes in macular vessels in eyes with DME treated with aflibercept using optical coherence tomography angiography (OCTA). METHODS This was a longitudinal, prospective, non-controlled, single arm study. The primary objective was the quantitative assessment of macular vessels over time in patients with DME treated with intravitreal aflibercept during a 48-week follow-up using OCTA. RESULTS Twenty-six DME eyes from 26 patients were included (mean age, 64.6 years; women, 53.8%; prior anti-VEGF treatment, 46.1%). Each eye received a mean (SD) of 7.2 (2.2) injections. The parameters of the FAZ did not change during the 48-week follow-up: the mean (SD) FAZ area varied from 0.19 (0.19) mm2 at baseline (n=22) to 0.23 (0.20) mm2 at week 48 (n=15), boundary from 1.54 (1.21) to 2.04 (1.20) mm and circularity from 0.45 (0.33) % to 0.57 (0.20) %. There was no change in perfusion density and vessel density of the macula in the 3-mm circle. As expected, mean central retinal thickness, macular volume and visual acuity improved during follow-up. DISCUSSION/CONCLUSION No change in macular perfusion was observed in eyes with DME during a 48-week follow-up after intravitreal injections of aflibercept. Randomized controlled trials using OCT-angiography in large populations with extended observation periods are needed to assess changes in macular vessels after intravitreal anti-VEGF treatment.

Abstract
PURPOSE Compare 0.30% sodium hyaluronate (0.30%HA) ocular gel with 0.18%HA eye drops in terms of improvement of ocular signs and symptoms, in patients with moderate to severe dry eye disease (DED). METHODS This was a multicentric, randomized, investigator-masked, non-inferiority, comparative study conducted over 84 days. Three visits were scheduled, testing fluorescein corneal and conjunctival staining (Oxford and Van Bijsterveld scores), tear film break-up time (TBUT), Schirmer test, DED symptoms, 5-Item-Dry-Eye-Questionnaire (5-DEQ), patient and investigator satisfaction and frequency of instillation. RESULTS At Day 35 (D35) and Day 84 (D84), both groups (n = 35 each) had a significant improvement in corneal staining (p < 0.001) with no inter-group difference. Van Bijsterveld score improved earlier (D35) for 0.30%HA suggesting a faster effect on conjunctival epithelium healing. There was no difference between the two concentrations in terms of TBUT or Schirmer improvements; however, the Schirmer test increase was only significant for 0.30%HA at D35 (p = 0.040). At D35 and D84, both groups showed similar improvements of DED symptoms and DEQ-5 score. Furthermore, treatment satisfaction was similar for the 2 formulations suggesting that daily use of 0.30%HA do not cause gel-related blurred vision disturbances. Frequency of instillation was similar for both groups. CONCLUSION Our study demonstrates the non-inferiority of 0.30%HA gel compared to 0.18%HA solution in patients with moderate to severe DED. Because of its gel formulation and higher HA concentration providing prolonged comfort without causing visual disturbances, 0.30%HA gel might be adapted for bedtime use or during the day in more severe conditions.

Final 4-year results of the RAINBOW real-world study: intravitreal aflibercept dosing regimens in France in treatment-naïve patients with neovascular age-related macular degeneration. Graefes Arch Clin Exp Ophthalmol 2022; 261:959-969. [PMID: 36399178 PMCID: PMC10049954 DOI: 10.1007/s00417-022-05900-6] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/20/2022] [Revised: 10/28/2022] [Accepted: 11/04/2022] [Indexed: 11/19/2022] Open
Abstract
Abstract
Purpose
The purpose of this study is to evaluate real-world treatment outcomes in patients with neovascular age-related macular degeneration (nAMD) treated with intravitreal aflibercept (IVT-AFL) in routine clinical practice in France.
Methods
RAINBOW (NCT02279537) was an ambispective, observational, 4-year study assessing IVT-AFL effectiveness, treatment patterns, and safety in patients with nAMD in France. Treatment-naïve patients prescribed IVT-AFL and treated according to local practice (pro re nata or treat-and-extend) were eligible. Three treatment cohorts were retrospectively identified based on their treatment pattern within the first 12 months: regular (3 initial monthly IVT-AFL injections received within 45–90 days after the first injection in month 0 and followed by injections every 2 months), irregular with the initial monthly injections, and irregular without the initial monthly injections. The primary endpoint was mean change in best-corrected visual acuity (BCVA) from baseline to month 12. The 48-month results are described here.
Results
Overall, the study included 516 patients (each with one study eye), and 30.2% of patients completed 48 months of IVT-AFL treatment. Mean change in BCVA from baseline (56.5 letters) to month 48 for patients with an assessment at both time points was + 1.1 (regular cohort, n = 47), + 0.1 (irregular cohort with initial monthly injections, n = 115), and − 1.3 letters (irregular cohort without initial monthly injections, n = 26), representing a decrease from the gains achieved at month 12. Mean number of IVT-AFL injections received by month 48 in the treatment cohorts was 14.9, 13.7, and 11.9, respectively. The safety profile of IVT-AFL was consistent with previous studies.
Conclusion
In RAINBOW, the 48-month results demonstrate a lack of long-term effectiveness of IVT-AFL treatment of nAMD due to progressive undertreatment in routine clinical practice in France. These real-world findings highlight the importance of 3 initial monthly IVT-AFL injections followed by continuous proactive treatment beyond the first year to achieve optimal functional outcomes.

Management of Patients with Diabetic Macular Edema Switched from Dexamethasone Intravitreal Implant to Fluocinolone Acetonide Intravitreal Implant. Pharmaceutics 2022; 14:pharmaceutics14112391. [PMID: 36365209 PMCID: PMC9693281 DOI: 10.3390/pharmaceutics14112391] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/12/2022] [Revised: 10/13/2022] [Accepted: 10/20/2022] [Indexed: 11/09/2022] Open
Abstract
To assess anatomical and functional outcomes after switching from dexamethasone implant (DEXi) to fluocinolone acetonide implant (FAci) in 113 diabetic macular edema eyes, a multicentric retrospective observational study was conducted. Seventy-five eyes (73.5%) were switched 1−8 weeks after their last DEXi. The mean best-corrected visual acuity improved to 59.8 letters at month 4 and remained stable during the follow-up. The mean central macular thickness (CMT) significantly decreased during the follow-up, with a minimum of 320.9 μm at month 3. The baseline CMT was higher in eyes that received the last DEXi >8 weeks versus <8 weeks before the first FAci (p < 0.021). After FAci injection, additional treatments were needed in 37 (32.7%) eyes. A longer diabetes duration (p = 0.009), a longer time between the last DEXi and the first FAci (p = 0.035), and a high baseline CMT (p = 0.003) were risk factors for additional treatments. The mean intraocular pressure was <19 mmHg at all timepoints, with no difference between eyes receiving the last DEXi ≤8 weeks or >8 weeks before the switch. Switching from DEXi to FAci in DME is effective and safe. A short time between the last DEXi and the first FAci reduced CMT fluctuations and the need for early additional treatments.

Recent Advances in Age-Related Macular Degeneration Therapies. Molecules 2022; 27:molecules27165089.

Abstract
Age-related macular degeneration (AMD) was described for the first time in the 1840s and is currently the leading cause of blindness for patients over 65 years in Western Countries. This disease impacts the eye’s posterior segment and damages the macula, a retina section with high levels of photoreceptor cells and responsible for the central vision. Advanced AMD stages are divided into the atrophic (dry) form and the exudative (wet) form. Atrophic AMD consists in the progressive atrophy of the retinal pigment epithelium (RPE) and the outer retinal layers, while the exudative form results in the anarchic invasion by choroidal neo-vessels of RPE and the retina. This invasion is responsible for fluid accumulation in the intra/sub-retinal spaces and for a progressive dysfunction of the photoreceptor cells. To date, the few existing anti-AMD therapies may only delay or suspend its progression, without providing cure to patients. However, in the last decade, an outstanding number of research programs targeting its different aspects have been initiated by academics and industrials. This review aims to bring together the most recent advances and insights into the mechanisms underlying AMD pathogenicity and disease evolution, and to highlight the current hypotheses towards the development of new treatments, i.e., symptomatic vs. curative. The therapeutic options and drugs proposed to tackle these mechanisms are analyzed and critically compared. A particular emphasis has been given to the therapeutic agents currently tested in clinical trials, whose results have been carefully collected and discussed whenever possible.

Comparative Effectiveness of Intravitreal Anti-Vascular Endothelial Growth Factor Therapies for Managing Neovascular Age-Related Macular Degeneration: A Meta-Analysis. J Clin Med 2022; 11:jcm11071834. [PMID: 35407439 PMCID: PMC8999505 DOI: 10.3390/jcm11071834] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/16/2022] [Revised: 03/09/2022] [Accepted: 03/16/2022] [Indexed: 12/11/2022] Open
Abstract
Intravitreal injections (IVI) of anti-vascular endothelial growth factor (anti-VEGF) have become the standard of care for age-related macular degeneration (AMD). Although most pivotal trials have used monthly injections, alternative strategies that enable the injections to be administered on a more flexible schedule, including pro re nata (PRN) and treat-and-extend (T&E) regimens, are being applied more frequently. This review sought to provide further scientific evidence about the visual outcomes and treatment burden among the currently available anti-VEGF agents and regimens, including aflibercept, ranibizumab, abicipar and brolucizumab. To this end, a systematic review of published randomized studies was conducted from the MEDLINE and EMBASE databases and the Cochrane library, and a meta-analysis was applied to the obtained data using single-means modeling to compare the efficacy and maintenance among the different available treatments and regimens at Years 1 and 2. Quality analysis identified the best-informed data for modeling purposes. Overall, 47 relevant publications were retrieved for the analysis. Superior efficacy, meaning that there were observed improvements in visual acuity (VA) and central retinal thickness (CRT), occurred with monthly versus PRN regimens, yet a higher IVI number was also observed. Conversely, the T&E regimens displayed similar efficacy to the monthly regimens, but with a reduced IVI number. Aflibercept T&E exhibited similar efficacy to ranibizumab T&E, but with significantly lower IVI numbers at both Year 1 (p < 0.0001) and Year 2 (p = 0.0011). Though all of the regimens resulted in maintained efficacy between Years 1 and 2, the required IVI number varied. The retrieved data did not enable other regimens or newer anti-VEGF agents such as brolucizumab to be compared. In conclusion, the T&E regimens were shown to be the most efficient, optimizing durable effectiveness whilst minimizing the IVI number in newly diagnosed exudative AMD, with aflibercept requiring the lowest IVI number.

Abstract
PURPOSE To evaluate the mean change in visual acuity at 52 weeks in patients with idiopathic choroidal neovascularization treated with aflibercept. METHODS We conducted a prospective noncomparative open-label Phase-II trial. The dosage regimen evaluated in this study was structured into two periods: (1) from inclusion to 20 weeks: a treat-and-extend period composed of three mandatory intravitreal injections, and complementary intravitreal injections performed if needed; (2) from 21 weeks to 52 weeks: a pro re nata period composed of intravitreal injections performed only if needed. RESULTS A total of 19 patients were included, and 16 completed the 52-week study. At baseline, the mean best corrected visual acuity was 66.56 (±20.72) letters (≈20/50 Snellen equivalent), and the mean central retinal thickness was 376.74 µm (±93.77). At 52 weeks, the mean change in the best-corrected visual acuity was +19.50 (±19.36) letters [95% confidence interval = +9.18 to +29.82]. None of the patients included lost ≥15 letters at 24 weeks or 52 weeks. The mean change in central retinal thickness was -96.78 µm (±104.29) at 24 weeks and -86.22 µm (±112.27) at 52 weeks. The mean number of intravitreal injections was 5.4 (±3.0) at 52-weeks. No ocular serious adverse events related to the treatment were reported. CONCLUSION The present analysis shows clinically significant functional and anatomical treatment effect of aflibercept in case of idiopathic choroidal neovascularization. The treat-and-extend regimen proposed after the first injection seems adequate to treat most neovessels.

Abstract
INTRODUCTION We aimed to assess the efficacy and safety of a standardized hyperbaric oxygen (HBO2) therapy protocol in patients with retinal artery occlusion (RAO). METHODS A retrospective study was conducted in our tertiary care center from July 2016 to September 2019. Patients experiencing central RAO and branch RAO for less than seven days were included. Once the diagnosis was made, patients were urgently referred to the HBO2 department to receive a first 90-minute HBO2 session at a pressure of 2.5 ATA. Patients underwent two daily sessions seven days a week for at least 15 days. If no reperfusion was seen on fluorescein angiography on Day 15, treatment was continued for an additional week with an assessment on Day 21. The primary endpoint was BCVA improvement defined as a decrease by 0.3 logMAR at one month. RESULTS Twenty-eight patients were included during the study period. Fifty-seven percent of patients were treated more than 12 hours after the onset of the first symptoms. The mean BCVA was 1.5 logMAR at the time of referral and improved to 0.9 logMAR after HBO2 (p=0.001). A multivariate analysis identified a high blood pressure (p=0.039) and a low initial BCVA (p=0.005) as poor prognostic factors. CONCLUSION Performing HBO2 sessions twice daily at a pressure of 2.5 ATA appears to be an effective and safe treatment for RAO.

Abstract
The NOTCH signaling system regulates a variety of cellular processes during embryonic development and homeostasis maintenance in different tissues and contexts. Hence, dysregulation of NOTCH signaling is associated with a plethora of human cancers, and there have been multiple efforts to target key components of this pathway. In this review, we briefly highlight the latest research advances in understanding HES6, a poorly studied component of the NOTCH pathway. We summarize the role of HES6 in cancers with a focus on uveal melanoma. Finally, we discuss the ongoing efforts to target the NOTCH-HES6 axis in cancers.

Abstract
Although its incidence has increased over the last decades, conjunctival melanoma (CM) remains a rare but challenging periocular malignancy. While there is currently no recognized standard of care, "no-touch" surgical excision followed by adjuvant treatments is usually recommended. Despite its small size, managing CM is challenging for clinicians. The first challenge is the high risk of tumour local recurrence that occurs in about one third of the patients. The management of locally advanced CM (≥T2) or multiple recurrences may require mutilating surgeries such as orbital exenteration (OE). The second challenge is the metastatic spread of CM that occurs in about one quarter of patients, regardless of whether complete surgical excision is performed or not. This highlights the infiltrative and highly aggressive behaviour of CM. Recently, attention has been directed towards the use of eye-sparing strategies to avoid OE. Initially, wide conservative surgeries followed by customized brachytherapy or radiotherapy have appeared as viable strategies. Nowadays, new biological insights into CM have revealed similarities with cutaneous melanoma. These new findings have allowed clinicians to reconsider the management of locally advanced CM with "medical" eye-sparing treatment as well as the management of metastatic spread. The aim of this review was to summarize the current and future perspectives of treatment for CM based on recent biological findings.

Abstract
Choosing a first-line treatment to optimize long-term outcomes is a major challenge for treating patients with neovascular age-related macular degeneration (AMD). The development of several new molecules makes it critical to identify the relevant factors to consider so as to provide an optimal risk-benefit ratio when initiating a treatment in naïve patients with neovascular AMD. This paper proposes a consensus established with the Delphi method (which includes a gradation in a consensus based on an analysis of the convergence rate of answers) to provide criteria that guide the ophthalmologist's decision for treatment initiation and follow-up in neovascular AMD patients. Fourteen questions were submitted to 93 French retina experts. Thirteen (93%) of the questions reached a consensus (≥50% of answers consensual). The criteria recommended to take into account were both efficacy and onset of action of the molecules, their safety, and the ability to decrease injection frequency. The primary criterion of expected efficacy of a molecule is a combination of the gain in visual acuity and resorption of retinal fluid. With regard to safety, experts recommend tighter follow-up for molecules currently in development, and at every scheduled visit, patients should be screened to identify early any potential adverse effects such as intraocular inflammation, retinal vasculitis or vascular occlusion. Experts also emphasize the importance of the packaging of the biological, with a preference toward prefilled syringes. Injection frequency is a key factor, and the authors recommended aiming for a maximal injection interval of 12 to 16 weeks. The stability of that maximum interval is also an important factor to consider in treatment selection.

Abstract
Purpose To evaluate the real-world effectiveness of intravitreal ranibizumab 0.5 mg (Lucentis) in improving visual acuity (VA) in adults with decreased VA due to diabetic macular edema (DME). Patients and Methods Real-world prospective observational 24-month study. Ranibizumab-naïve patients (n=116) were enrolled, treated and followed up according to investigators’ usual procedures. Outcomes included change from baseline to month 24 in best-corrected VA (BCVA; primary outcome), central retinal thickness (CRT), treatment exposure and safety. Results Overall, 62.9% of patients completed the study per protocol, 68.6% completed the induction phase (first three injections one month apart). On average, patients had 12.5 ophthalmologist visits and 5.74 injections in year 1, decreasing to 4.6 visits and 1.94 injections in year 2. Mean baseline BCVA was 58.4 letters, mean gain at M24 was +6.08 letters (95% CI: 2.95, 9.21). Gains were higher for patients who completed induction, and for patients who did not switch treatment. Mean CRT improved by 149.17 μm at M24. There were no new safety signals. BCVA variation of ≥6 letters by M3 was predictive of BCVA gains at M24 (p=0.007), as was hypertension medication at baseline (p=0.022). Conclusion Real-world ranibizumab treatment improved VA in DME patients, despite fewer injections than recommended.

Abstract
Intratumor heterogeneity has been recognized in numerous cancers as a major source of metastatic dissemination. In uveal melanomas, the existence and identity of specific subpopulations, their biological function and their contribution to metastasis remain unknown. Here, in multiscale analyses using single-cell RNA sequencing of six different primary uveal melanomas, we uncover an intratumoral heterogeneity at the genomic and transcriptomic level. We identify distinct transcriptional cell states and diverse tumor-associated populations in a subset of the samples. We also decipher a gene regulatory network underlying an invasive and poor prognosis state driven in part by the transcription factor HES6. HES6 heterogenous expression has been validated by RNAscope assays within primary human uveal melanomas, which further unveils the existence of these cells conveying a dismal prognosis in tumors diagnosed with a favorable outcome using bulk analyses. Depletion of HES6 impairs proliferation, migration and metastatic dissemination in vitro and in vivo using the chick chorioallantoic membrane assay, demonstrating the essential role of HES6 in uveal melanomas. Thus, single-cell analysis offers an unprecedented view of primary uveal melanoma heterogeneity, identifies bona fide biomarkers for metastatic cells in the primary tumor, and reveals targetable modules driving growth and metastasis formation. Significantly, our findings demonstrate that HES6 is a valid target to stop uveal melanoma progression.

Abstract
Uveal melanoma (UM) is an aggressive and deadly neoplasm. In recent decades, great efforts have been made to obtain a more comprehensive understanding of genetics, genomics and molecular changes in UM, enabling the identification of key cellular processes and signalling pathways. Still, there is no effective treatment for the metastatic disease. Intratumoural heterogeneity (ITH) is thought to be one of the leading determinants of metastasis, therapeutic resistance and recurrence. Crucially, tumours are complex ecosystems, where cancer cells, and diverse cell types from their microenvironment engage in dynamic spatiotemporal crosstalk that allows cancer progression, adaptation and evolution. This highlights the urgent need to gain insight into ITH in UM and its intersection with the microenvironment to overcome treatment failure. Here we provide an overview of the studies and technologies to study ITH in human UMs and tumour micro-environmental composition. We discuss how to incorporate ITH into clinical consideration for the purpose of advocating for new clinical management. We focus on the application of single-cell transcriptomic analysis and propose that understanding the driving forces and functional consequences of the observed tumour heterogeneity holds promise for changing the treatment paradigm of metastatic UMs, surmounting resistance and improving patient prognosis.

Eye amputation following lifitegrast treatment for ocular graft-versus-host disease: First case report. J Fr Ophtalmol 2021; 44:652-657. [PMID: 33858697 DOI: 10.1016/j.jfo.2020.12.004] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/11/2020] [Revised: 12/15/2020] [Accepted: 12/16/2020] [Indexed: 11/19/2022]
Abstract
Graft-versus-host disease (GVHD) is a common complication in patients undergoing allogeneic stem cell transplantation for acute myeloblastic leukemia that could be very difficult to treat. Lifitegrast 5% (Xiidra@, Novartis), a new immunosuppressive eye drop, was recently approved by the FDA for the treatment of severe dry eye and is currently under review by the European Medicines Agency. In France, lifitegrast has been approved by the French authorities for temporary use in refractory dry eye syndrome resistant to tear substitutes and topical cyclosporine. To date, serious complications have been reported only exceptionally. In this article, we report the case of a 65-year-old patient with a medical history of acute myeloid leukemia (AML) diagnosed in 2015 who received a first matched related donor transplant. In 2019, this patient developed chronic GVH involving the skin, oral mucosa and eye. Despite taking topical and systemic medications for 3 months, the patient did not report relief of ocular symptoms. Therefore, lifitegrast was prescribed. To our knowledge, we report the first case of corneal perforation in which evisceration was required following treatment with topical lifitegrast for chronic GVH. In the case presented here, it can be assumed that the underlying mechanisms leading to corneal perforation are multifactorial. Using drug accountability criteria, lifitegrast appears to be strongly associated with the development of bacterial keratitis and corneal perforation.

Abstract
PURPOSE To evaluate the validity, reproducibility, and feasibility of the "Color Vision Evaluation Test" (CVET) for the diagnosis of congenital dyschromatopsia. DESIGN Prospective, monocentric, sensitivity, and specificity analysis study comparing the CVET with the Farnsworth 15 Hue standard test (15 Hue STF). METHODS A total of 155 children from the Paediatric University Hospital of Nice were screened (both eyes) using Ishihara's pseudoisochromatic cards, which allowed dividing them into a dyschromatic group and a control group. All children underwent twice the 15 Hue STF and the CVET with at least 7 days between both series of tests. RESULTS Patients' mean age was 7.56 ± 3.51 years in the dyschromatic group and 8.92 ± 2.9 years in the control group. At the first evaluation, the sensitivity and specificity were 95.7% and 96.4%, respectively, for the CVET and 75% and 58.9%, respectively, for the 15 Hue STF (P < .001). The reproducibility of the CVET was 100%, whereas that of the 15 Hue STF was 88.4% (P = .01). The mean test explanation duration was 18.8 seconds for the CVET and 17.7 seconds for the 15 Hue STF (P = .3). In the dyschromatic group, the mean duration of the CVET was always significantly longer than that of the 15 Hue STF (P < .001). The children subjectively preferred to undergo the CVET rather than the 15 Hue STF in 84.6% of cases (P < .001). CONCLUSIONS The CVET is a rapid, reliable, and reproducible test for the diagnosis of congenital dyschromatopsia. It is accessible to young children.

Abstract
Conjunctival melanoma (CM) iss a rare and aggressive tumour that is increasing in frequency. The prognostic value of PD-L1 expression, alone or in combination with CD8 and PD-1 expression and the BRAF and NRAS status, has not been determined in CM to date. We evaluated the expression of PD-L1, CD8, PD-1 in CM and investigated whether there was an association between the expression of these markers and the BRAF and NRAS molecular profile as well as some clinico-pathological criteria. A total of sixty-five CM were assessed for PD-L1, PD-1, and CD8 expression by immunohistochemistry (IHC) and for BRAF and NRAS genomic alterations using molecular biology techniques and anti-BRAF and anti-NRAS antibodies. PD-L1 expression in tumour cells (TC) was very low or absent but detected in tumour-infiltrating immune cells (IC). A correlation was observed between the expression of PD-L1, CD8, and PD-1 in IC. No correlation between PD-L1 expression (in tumour and/or immune cells) and BRAF or NRAS mutations was observed. PD-L1 expression in IC correlated with a higher pTNM stage and PD-L1 expression in TC with worse disease-specific survival. PD-L1 expression is a potential prognostic biomarker that correlates with poor prognosis in CM patients.

Abstract
Optimizing treatment regimens for anti-angiogenic drugs is now a major issue in the management of patients with exudative AMD. The evolution of these approaches has led retinologists to favor so-called proactive administration regimens, such as Treat-and-Extend (T&E), which make it possible to anticipate recurrence and to plan intravitreal injections of anti-angiogenic drugs in advance. Nevertheless, a real need to standardize the application of this regimen has been identified. This article proposes a consensus based on the Delphi methodology, which might provide a guide for ophthalmologists to manage patients with exudative AMD using the T&E protocol. While some aspects remain debated to date, this article provides elements to guide the implementation of T&E. The experts recommend that a loading dose of 3 monthly injections should be administered before starting T&E. They also recommend adjusting the reinjection intervals by±2 weeks in a standardized fashion. The intervals are then decreased in the presence of anatomical and/or functional deterioration, maintained when the interval of recurrence is identified, and increased when anatomical and/or functional improvement is observed. A maximum interval between 3 and 4 months is recommended by the experts, with maintenance of the maximum interval for 1 year before considering a possible exit from the T&E protocol. In the event of a significant decrease in visual acuity related to the disease along with significant anatomical degradation, it is recommended to restart monthly injections. In the case of bilateral disease, when synchronized timing of injections for both eyes is desired, the experts recommend using the shorter of the two intervals.

Abstract
Lymphoma is the most common orbital malignancy in adults. Among the types of lymphoma, mantle cell lymphoma is a particularly aggressive form, often discovered through systemic involvement, with a dismal prognosis due to frequent recurrences. It is secondary to a t (11 ; 14) (q13; q32) chromosomal translocation resulting in an anti-apoptotic signal via overexpression of Bcl-2. Treatment is based on R-CHOP poly-chemotherapy. We describe the case of a patient with an orbital recurrence of mantle cell lymphoma successfully treated with oral Bcl-2 inhibitor monotherapy. A 58-year-old man who was treated with R-CHOP 8 years ago for mantle cell lymphoma, in remission for 5 years, presented with progressive decreased visual acuity in the left eye, along with binocular diplopia. Clinical examination revealed a decrease in visual acuity in the left eye to 1/20 Parinaud 20 and a relative afferent pupillary defect on the left. External examination revealed a left cranial nerve VI palsy, 2mm of painless proptosis, and hypesthesia of the left V1 territory, leading to a diagnosis of left orbital apex syndrome. The disc and macular OCT were normal. The visual field showed enlargement of the left blind spot. An emergency CT scan and MRI revealed an apical extraconal tissue mass infiltrating the medial rectus muscle, extending to the superior orbital fissure, optic canal and left cavernous sinus, hyperintense on T2 weighted images and isointense on T1. The morphological appearance was strongly suggestive of an infiltrative lymphomatous process. An 18 FDG PET-scan identified the orbital lesion as well as enhancing lesions in the axilla and colon; given the clinical features and test results, the diagnosis of recurrent mantle cell lymphoma was made without biopsy. Treatment with Venetoclax (Bcl-2 inhibitor) was initiated. At one month of treatment, the orbital apex syndrome had entirely resolved, with visual acuity increased to 8/10 Parinaud 4 and a metabolic return to normal on PET scan. The PET scanner and clinical examination at 3 months were entirely normal. At the one-year follow-up visit, the patient was still on Venetoclax, the clinical examination was unchanged, and the PET-scan still showed a complete metabolic response.

Abstract
AIMS Clinical outcomes of diabetic macular edema (DME) have been widely described, but data on diabetic retinopathy perceptions by diabetes patients are limited. The aim of this survey was to explore the lived experience, knowledge, fears and expectations about disease, and treatment in patients with diabetes and macular edema treated with intravitreal injections (IVTI) and to characterize patient profiles. METHODS Cross-sectional survey including a preliminary qualitative phase (20 patients with DME, treated or treatment-naive, 5 female and 15 male, age 36-74 years) followed by a quantitative survey (116 patients treated with IVTI for DME). Data ASKIA Analyze (version 5.3.3.5) was used for descriptive statistics, and R software (version 3.4.1) for multiple correspondence analysis. RESULTS The qualitative phase identified the wording used by patients and information helpful to propose modalities of response in the quantitative phase. In the quantitative survey (116 patients, mean age 66.6 years), most patients were treated with anti-vascular endothelial growth factor. Overall, 71.9% reported that the disease negatively affected their daily activities and 33.1% considered that regular visits to the ophthalmologist were disrupting their life. Treatment expectations differed significantly between patients in terms of disease experience (visit and injection schedules), fears and feelings, and relationship with physicians, allowing three patient profiles to be identified: "Worried" patients (n = 45) felt isolated and were worried about the need for repeated treatment and possible side effects. They were mainly active men aged < 60 with type I diabetes (T1D) and DME diagnosed for > 2 years; "Curious" patients (n = 21) experienced insufficient support and requested more information on their disease and existing treatments. They were mainly single women aged 60-69 years; "Passive" patients (n = 50) felt sufficiently informed by their ophthalmologist and were not concerned by DME. They were older (mean age: 70 years) and mainly type 2 diabetic men. CONCLUSIONS Patients with diabetes and macular edema treated with IVTI form a heterogeneous group regarding fears and expectations. Different patient profiles were identified and need to be confirmed in larger studies. A better understanding of psychological profiles may optimize compliance of diabetic patients.

Abstract
PURPOSE Orbital exenteration is a radical and disfiguring surgery mainly performed for treating orbital malignancies. Recently, several studies found favorable results in terms of overall survival with eye-sparing surgeries combined with targeted therapies and/or radiotherapy. The aim of this study was to assess the incidence of orbital exenteration and its evolution in France between 2006 and 2017. METHODS A national observational cohort study was conducted in France between January 2006 and December 2017. Data were collected from the national PMSI (Programme de Médicalisation des Systèmes d'Information) database provided by the CNAM (Caisse Nationale de l'Assurance Maladie). All patients undergoing orbital exenteration over the study period in France were included. RESULTS One thousand and fifty-seven patients were included. The mean annual number of orbital exenterations was 88.1 (63-117), corresponding to a mean incidence of 0.1/100,000 inhabitants/year. A male predominance was noted (n = 626, 59.2%). Exenteration was mainly performed between 75 and 79 years. The underlying etiology was available for 821 patients (77.7%): malignancies were the most common (n = 755; 92.0%) followed by infectious diseases (n = 16; 1.9%). Over the study period, no statistical difference in the mean incidence of orbital exenteration was found (p = .132). CONCLUSION The mean annual incidence of orbital exenteration was 0.1/100,000 inhabitants in France and was not significantly modified during the study period.

Abstract
Background To review treatment outcomes from real-world data of patients with neovascular age-related macular degeneration (nAMD) treated with intravitreal aflibercept (IVT-AFL) injection. Methods RAINBOW (ClinicalTrials.gov, NCT02279537) is an ongoing, observational, 4-year study to monitor the effectiveness and safety of IVT-AFL in patients with nAMD in clinical practice in France. Treatment-naïve patients diagnosed with nAMD who had been prescribed IVT-AFL by their treating physician were eligible. The regimens of interest were regular treatment interval cohort (patients who received three initial monthly IVT-AFL injections followed by regular injections every 2 months) and two irregular treatment interval cohorts (with and without three initial monthly injections). Here we describe results at 24 months in patients according to IVT-AFL treatment regimen. Results The mean change in best-corrected visual acuity (BCVA) with IVT-AFL from baseline to 24 months was + 3.0 letters in the overall population (P < 0.05 vs baseline). The mean change was positive for the regular and irregular treatment interval cohorts with initial doses (+ 4.9 and + 4.0 letters, respectively; P < 0.05 vs baseline) and negative for the irregular treatment interval cohort without initial doses (− 2.5 letters; P = 0.365 vs baseline) at 24 months. The mean overall number of IVT-AFL injections over 12 and 24 months was 6.0 and 8.8, respectively. The most common ocular adverse events were lack of efficacy (6.3%), vitreous floaters (2.7%), and increased lacrimation (1.7%). Conclusions In the real-world RAINBOW study, visual outcomes observed at 24 months were consistent with results from the primary endpoint at 12 months. In this study, treatment-naïve patients who received three initial IVT-AFL doses and regular IVT-AFL treatment over the first 24 months experienced better visual outcomes than patients who received no initial doses and an irregular treatment regimen. Trial registration www.ClinicalTrials.gov (NCT02279537). Registered 29 October 2014.
