Effects of Intense Pulsed Light on Presumed Neuropathic Pain Associated with Meibomian Gland Dysfunction: A Before-After Study.

Purpose: Meibomian gland dysfunction (MGD) may cause chronic ocular surface pain (COSP) with a neuropathic component that can significantly impact quality of life and be poorly responsive to conventional treatments of MGD. Intense pulsed light (IPL) is an emerging treatment already acknowledged as improving refractory MGD, potentially modulating inflammatory mediators on the ocular surface. This study aimed to assess the impact of IPL on COSP associated with unresponsive MGD. Methods: A monocentric prospective study has been conducted from 2021 to 2023 on patients presenting with moderate MGD and COSP non-responsive to conventional treatments of MGD. Neuropathic pain components were suspected when severe discomfort (OSDI score above 33/100) was observed despite moderate objective signs. Three sessions of IPL were performed at a two-week interval. The primary outcome was change in OSDI at day 60. Secondary outcomes included OSDI modification at D120, DEQ-5, and Pentascore results at D60/D120, together with changes in clinical [Schirmer I, Fluorescein Break-up time (BUT), fluorescein staining, and MGD classification] and paraclinical tests [noninvasive BUT, tear meniscus height (TMH), and meibography]. Results: A significant improvement of COSP (p < 0.05 for changes in OSDI and Pentascore results) was observed 2 and 4 months after the last IPL session, together with an improvement in tear film stability, corneal epitheliopathy, meibomian gland obstruction, and TMH. Conclusion: The results of this study suggest the beneficial effect of IPL on neuropathic component of COSP associated with MGD. The underlying mechanisms involved in that improvement, presumably related to downgrading of inflammatory effectors, remain however to be explored.

Human papilloma virus (HPV) presence in primary tumors of the lacrimal sac: a case series and review of the literature.

Primary tumors of the lacrimal sac (PTLS) are a rare subtype of ocular adnexa tumors, with potentially life-threatening clinical course. There has been growing evidence of human papilloma virus (HPV) as an etiological agent in these tumors.In this retrospective observational case series, we report three cases of PTLS. All three underwent an initial dacryocystorhinostomy revealing a tissular mass in the lacrimal sac. Histological findings were respectively epithelial papilloma, epithelial Malpighian papilloma, and undifferentiated epidermoid carcinoma. PCR evaluation identified HPV serotype 6 in the first case and 16 in the third, and high p16 expression was found in the second case.These three cases of PTLS with HPV detection complement 36 other cases identified in the literature, further incriminating HPV in the pathogenesis of these neoplasms. Ophthalmologists must remain wary of chronic lacrimal occlusion symptoms, and resort to CT scan and orbital Doppler sonography whenever first-line treatment fails.

Paediatric non-infectious granulomatous uveitis: a retrospective cohort study.

INTRODUCTION: Paediatric granulomatous uveitis (PGU) is rare. In addition, lack of awareness often leads to delayed diagnosis and poor visual outcome. Identifying the underlying cause and deciding how best to treat each patient is challenging. OBJECTIVES: To evaluate the demographics, aetiologies, complications, treatments, and visual prognosis of paediatric non-infectious granulomatous uveitis. METHODS: Retrospective chart review of non-infectious PGU occurring in children before the age of 16 years recruited from the Paediatric Rheumatology Unit, Bicêtre Hospital, France, from 2001 to 2023. RESULTS: We included 50 patients with 90 affected eyes: 29 with idiopathic uveitis, 15 with sarcoidosis, 5 with juvenile idiopathic arthritis, and one with Vogt-Koyanagi-Harada disease. Median age at diagnosis was 9.8 years (range 7.2-12.5). The sex-ratio M/F was 0.52. The most common features of PGU were: panuveitis (56%), bilateral (84%), and chronic (84%). Sarcoidosis was the most frequent diagnosis after idiopathic disease, particularly in the presence of lymphopenia and hypergammaglobulinemia. Uveomeningitis was present in 12% of cases. Upon diagnosis, ocular complications were present in 68 of 90 eyes (76%) particularly in cases of panuveitis. The most commonly used treatments were systemic corticosteroids (72%) and methotrexate (80%). Twenty-three percent of eyes were in remission at last follow-up, 68% were inactive and 4% remained active. The median duration of follow-up was 5.8 years. CONCLUSION: We report the largest cohort of PGU. PGU were mostly idiopathic and had a high rate of complications. Sarcoid and idiopathic panuveitis are serious illnesses in which disease-modifying therapy should be initiated at diagnosis to improve management.

Efficacy and Safety of Amenamevir, a Helicase-Primase Inhibitor for the Treatment of Acyclovir-Resistant Herpes Simplex Virus 1 Keratitis.

PURPOSE: The purpose of this study was to describe the efficacy and tolerance of amenamevir (AMNV), an inhibitor of the viral helicase-primase, for the treatment of recalcitrant herpes simplex keratitis (HSK) caused by acyclovir-resistant (ACVR) herpes simplex virus 1 strains. METHODS: In this retrospective case series, 6 consecutive patients with HSK caused by an ACVR herpes simplex virus 1 strain with a failure of conventional antiviral therapy were included after having been treated with AMNV (there was no control group of comparable patients for whom previous treatment would have been continued despite its inefficacy). Medical files were assessed for clinical data including reason(s) for AMNV introduction (frequent recurrences despite appropriate preventive antiviral treatment and/or clinical resistance to suppressive antiviral treatment of an ongoing clinical relapse), genotypical resistance to herpes simplex virus 1 documentation, immune status, clinical types and number of HSK episodes before and during AMNV treatment, adverse effects observed during AMNV treatment, and best corrected visual acuity. RESULTS: Of 6 patients, 4 (66%) did not experience a single recurrence during AMNV therapy while 2 others had recurrences (1 over 24 months of treatment and 2 over 23 months, ie two-fold less frequently than with conventional preventive treatment). On the overall history of these 6 patients, AMNV appeared to be associated with a reduction in HSK recurrences, with a mean of only 0.02 ± 0.04 episodes/month during follow-up under AMNV as compared to 0.14 ± 0.04 episodes/month in the year preceding AMNV introduction (P = 0.03). Improvement in vision acuity was also observed (mean best corrected visual acuity 0.17 ± 0.12 logarithm of the minimum angle of resolution at the end of follow-up vs. 0.30 ± 0.35 before AMNV onset), albeit nonsignificant probably due to the limited number of patients (P = 0.38). Neither clinical nor biological adverse effects were observed while under AMNV during the follow-up (16.5 ± 5.8 months). CONCLUSIONS: Although there was no control group, AMNV may be a valuable option to reduce ACVR HSK recurrences.

Ocular surface toxicities associated with modern anticancer therapies.

Cancer treatments have recently shifted from broad-spectrum cytotoxic therapies to more focused treatments, maximizing anticancerous activity while reducing toxicity to healthy cells. These modern anticancer therapies (MATs) encompass a wide range of innovative molecules that include immune checkpoint inhibitors and other targeted anticancer therapies, comprising antibody drug conjugates and inhibitors of signal transduction. Some MATs are associated with ocular surface adverse events that can cause severe discomfort and even lead to loss of vision. While these complications remain rare, they are probably underreported. It is likely that both oncologists and ophthalmologists will come across MATs-associated ocular surface-adverse events in their practices, owing to the increasing number of patients being treated with MATs. Rapid identification of ocular surface-adverse events is crucial, as early intervention can manage these conditions to avoid vision loss and reduce negative impacts on quality of life. We discuss characteristics of ocular surface pathologies attributed to MATs, describe the suspected underlying pathophysiological mechanisms, and outline the main lines of treatment.

Ocular involvement in pediatric Behçet's disease: is it different than in adults? (a short case series and mini review).

BACKGROUND: Pediatric Behçet's disease (PBD) is rarer than BD and can be a challenging diagnosis as clinical picture may be incomplete. As in adult patients, sight-threatening ocular manifestations may lead to diagnosis. In this study, we aimed to report a series of cases of PBD with ocular manifestations and provide a review of the literature. METHODS: Retrospective case series of PBD patients with ocular manifestations. Demographic, ophthalmological and systemic data at presentation and during follow-up were collected and analyzed. RESULTS: Four patients, aged 13.0 ± 2.9 years (9-16) were included. Posterior uveitis with retinal vasculitis, papillitis and macular edema was present in all patients, with associated anterior uveitis in 2 cases. Other features included occlusive vasculitis (2/4) and necrotizing retinitis (2/4). All patients were improved by systemic treatments except one patient with severe bilateral optic neuropathy. Ocular manifestations were the presenting symptoms in 3/4 cases. CONCLUSION: Ocular manifestations and systemic associations of PBD are comparable to those encountered in adult patients. The lack of complains in pediatric patients may lead to a longer diagnosis delay, especially in unilateral uveitis. Aggressive and long-term treatment is mandatory to prevent vision loss and recurrences.

IS CATARACT SURGERY SAFE IN PATIENTS WITH STELLATE NONHEREDITARY IDIOPATHIC FOVEOMACULAR RETINOSCHISIS?

PURPOSE: To assess the retinal modifications after cataract surgery in a patient presenting with stellate nonhereditary idiopathic foveomacular retinoschisis. METHODS: Retrospective analysis of the evolution of retinal status in a 64-year-old patient with unilateral stellate nonhereditary idiopathic foveomacular retinoschisis who underwent cataract surgery in the affected eye. RESULTS: Visual acuity improved after surgery, reaching back the level described by the patient before the cataract onset, whereas fundus retinographies and optical coherence tomographies were stable at one month after surgery, compared with the preoperative images. DISCUSSION: This first case-report of the evolution of stellate nonhereditary idiopathic foveomacular retinoschisis after cataract surgery suggests that this retinal condition is not modified by the surgical procedure, which however needs to confirmed by larger cohorts.

Rubella virus-associated uveitis: The essentiality of aqueous humor virological analysis.

AIMS / BACKGROUND: Rubella virus-associated uveitis (RVAU) classically presents with the clinical features of Fuchs uveitis syndrome (FUS). We report a series RVAU, and discuss the relevance of available diagnostic strategies, and how vaccination could potentially prevent disease. METHODS: We retrospectively included patients with RV-positive aqueous humor (AH) with RT-PCR and/or intraocular RV-IgG production, between January 2014 and December 2019. RV-IgG titers from AH and serum were compared with other virus-specific IgG titers (VZV and/or CMV and/or HSV-1), to determine the derived Goldmann-Witmer coefficient (GWC'). Clinical findings at presentation and during follow-up are reported, as well as the anti-RV vaccination status. RESULTS: All 13 included patients demonstrated intraocular synthesis of RV-IgG (median GWC': 9.5; 3.2-100). RV-RNA was detected in one patient while PCR results were negative for other HSV1, VZV and CMV. The mean delay in diagnosis was 13 ± 12.6 years, with an initial presentation of FUS in only 3 patients (23%). Only four patients had been vaccinated, but all after the recommended age. CONCLUSION: As RVAU is a pleiomorphic entity, virological analysis (RV RT-PCR and GWC') of aqueous humor is essential to improve the diagnosis and management of this entity. Improper vaccination against RV appears to be implicated in RVAU.

Specific postoperative complications of vitrectomy in hereditary transthyretin amyloidosis.

INTRODUCTION: Vitrectomy may improve visual acuity of hereditary transthyretin amyloidosis (ATTRv) patients presenting with vitreous opacities but is associated with severe complications. The objective of this study is to report visual outcomes, early and late complications of a series of ATTRv patients who underwent vitrectomy in the French ATTRv reference center. METHODS: This retrospective, single-center study, included all ATTRv patients who underwent vitrectomy between 2002 and 2017. Data were collected on pre and postoperative best corrected visual acuity (BCVA) and early and late postoperative complications. RESULTS: A total of 21 eyes from 15 patients were included. The mean postoperative follow-up was 40 ± 20 months (6-160 months). BCVA increased from 0.7 ± 0.4 LogMAR preoperatively to 0.3 ± 0.4 LogMAR (p = 0.003) at last postoperative visit. During follow-up, all initially glaucomatous eyes worsened, with three eyes (37%) requiring filtering surgery and two eyes (25%) had further vision loss. Among non-glaucomatous patients, four eyes (31%) developed glaucoma with two requiring trabeculectomy and one eye (8%) had further vision loss. Three eyes (three patients) presented with complications of amyloid angiopathy. Three eyes (three patients) experienced recurrence of vitreous deposits requiring surgical revision. CONCLUSION: Due to the potential complications, vitrectomy in ATTRv requires specific perioperative management and life-long postoperative monitoring.

Peripheral ulcerative keratitis in rheumatoid arthritis patients taking tocilizumab: paradoxical manifestation or insufficient efficacy?

OBJECTIVES: Peripheral ulcerative keratitis (PUK) is a severe corneal condition associated with uncontrolled RA. Tocilizumab (TCZ) is used to control RA, however, episodes of paradoxical ocular inflammation have been reported in TCZ-treated patients. We report a case series of PUK in TCZ-treated RA patients with ophthalmological and systemic findings and discuss the potential underlying mechanisms. METHODS: Four patients (six eyes), 47-62 years of age, were included. At the onset of PUK, the median duration of RA was 13 years [interquartile range (IQR) 3-13] and the median treatment with TCZ was 9 months (IQR 3-14). Two patients had active disease [28-joint DAS (DAS28) >3.2] and the disease was controlled in two patients (DAS28 ≤3.2). RESULTS: TCZ was initially replaced by another immunomodulatory treatment in all patients and later reintroduced in two patients without PUK recurrence. Corneal inflammation was controlled in all cases with local and systemic treatments, with severe visual loss in one eye. CONCLUSION: PUK may occur in patients with long-standing RA after a switch to TCZ and can be interpreted, depending on the context, as insufficient efficacy or a paradoxical manifestation. These cases highlight the urgent need for reliable biomarkers of the efficacy and paradoxical reactions of biologics.

Risdiplam treatment has not led to retinal toxicity in patients with spinal muscular atrophy.

OBJECTIVE: Evaluation of ophthalmologic safety with focus on retinal safety in patients with spinal muscular atrophy (SMA) treated with risdiplam (EVRYSDI®), a survival of motor neuron 2 splicing modifier associated with retinal toxicity in monkeys. Risdiplam was approved recently for the treatment of patients with SMA, aged ≥ 2 months in the United States, and is currently under Health Authority review in the EU. METHODS: Subjects included patients with SMA aged 2 months-60 years enrolled in the FIREFISH, SUNFISH, and JEWELFISH clinical trials for risdiplam. Ophthalmologic assessments, including functional assessments (age-appropriate visual acuity and visual field) and imaging (spectral domain optical coherence tomography [SD-OCT], fundus photography, and fundus autofluorescence [FAF]), were conducted at baseline and every 2-6 months depending on study and assessment. SD-OCT, FAF, fundus photography, and threshold perimetry were evaluated by an independent, masked reading center. Adverse events (AEs) were reported throughout the study. RESULTS: A total of 245 patients receiving risdiplam were assessed. Comprehensive, high-quality, ophthalmologic monitoring assessing retinal structure and visual function showed no retinal structural or functional changes. In the youngest patients, SD-OCT findings of normal retinal maturation were observed. AEs involving eye disorders were not suggestive of risdiplam-induced toxicity and resolved with ongoing treatment. INTERPRETATION: Extensive ophthalmologic monitoring conducted in studies in patients with SMA confirmed that risdiplam does not induce ophthalmologic toxicity in pediatric or adult patients with SMA at the therapeutic dose. These results suggest that safety ophthalmologic monitoring is not needed in patients receiving risdiplam, as also reflected in the United States Prescribing Information for risdiplam.

Assessment of the duration of surgery and patient turnover after the incorporation of a standardized intracameral combination of mydriatics and anesthetics for cataract surgery.

PURPOSE: To evaluate changes in clinical outcomes, duration, and workflow of cataract surgery, before and after the introduction of a commercially available intracameral combination of 2 mydriatics (phenylephrine, tropicamide) and 1 anesthetic (lidocaine) (ICMA). SETTING: Service d'Ophtalmologie, Hôpital Bicêtre, Université Paris Sud., Le Kremlin-Bicêtre, France. DESIGN: Retrospective chart review. METHODS: Three series of patients who underwent cataract surgery were grouped according to when they had surgery: just before ICMA was approved (early 2016, Series I); just after implementation of ICMA as the standard procedure for surgery (late 2016, Series II); and 21 months after using ICMA routinely for surgery (2018, Series III). Data were collected on patient turnover during the day of surgery and surgical outcomes. RESULTS: The study population comprised of 51, 47, and 51 patients in Series I, II, and III respectively. There were no statistical differences between series in the mean change in corrected distance visual acuity from preoperatively to 1 month postoperatively and in complications (P > .05, all comparisons). The mean duration of surgery was significantly shorter in Series III and II, compared with Series I (13.18 ± 4.05 and 13.62 ± 5.26 vs 15.82 ± 6.01 minutes; P = .023 and P = .041, respectively). The mean patient rotation was statistically significantly shorter in Series III compared with Series I (41.50 ± 8.31 vs 47.79 ± 14.66 minutes, respectively; P = .028). CONCLUSIONS: Implementing ICMA as a routine procedure in cataract surgery resulted in similar vision and safety outcomes than the usual topical eyedrop regimen, while significantly reducing the total surgery and rotation times. Hence, patient turnover during the surgical session was optimized while maintaining safety and efficacy of the procedure.

The 2016-2019 ImmunoTOX assessment board report of collaborative management of immune-related adverse events, an observational clinical study.

PURPOSE: We investigated the activities of an ImmunoTOX board, an academic, multidisciplinary group of oncologists and organ specialists that adopts a real-life, case-by-case approach in the management of patients with immune-related adverse events (irAEs). EXPERIMENTAL DESIGN: The ImmunoTOX assessment board was set up in 2016 at Gustave Roussy in France. It meets every 2 weeks to discuss the case-by-case management of patients presenting with irAEs. Here, we describe the ImmunoTOX board's activities between 2016 and 2019. RESULTS: Over study period, 398 requests (concerning 356 patients) were submitted to the ImmunoTOX board. Most of the requests concerned the putative causal link between immunotherapy and the irAE (n = 148, 37%), followed by possible retreatment after temporary withdrawal because of an adverse event (n = 109, 27%), the clinical management of complex situations (n = 100, 25%) and the initiation of immunotherapy in patients with pre-existing comorbidities (n = 41, 10%). The ImmunoTOX board discerned 273 irAEs. The five organ systems most frequently involved by irAEs were lung (n = 58, 21%), gastrointestinal tract (n = 36, 13%), liver or biliary tract (n = 33, 12%), musculoskeletal system (n = 27, 10%), and nervous system (n = 23, 8%). The time to occurrence was shorter for severe irAEs (grade III and VI) than for mild irAEs (grades I and II), with medians of 47 and 91 days, respectively (p = 0.0216). CONCLUSION: The main medical needs in the management of irAEs involved the lung organ. Severe irAEs were expected to occur earlier than mild irAEs. This real-life study can help to better estimate medical needs and therefore help to assess the management of irAEs.

Conjunctival lymphangiectasia as a biomarker of severe systemic disease in Ser77Tyr hereditary transthyretin amyloidosis.

AIMS: To investigate the relationship between the ophthalmic and systemic phenotypes in patients with hereditary transthyretin amyloidosis with the S77Y mutation (ATTRS77Y). METHODS: In this cross-sectional study, patients with genetically confirmed ATTRS77Y amyloidosis were enrolled. All patients underwent complete neurological examination, including staging with the Neuropathy Impairment Score (NIS), Polyneuropathy Disability (PND) score; complete cardiological evaluation, including echocardiography, cardiac MRI and/or cardiac scintigraphy and complete ophthalmic evaluation, including slit lamp examination and fundus examination. Ocular ancillary tests (fluorescein and indocyanine green angiography, and anterior segment optical coherence tomography) were performed in cases with abnormal findings. The Kruskal-Wallis test was used for quantitative outcomes and Fisher's exact test for qualitative outcomes. Statistical significance was indicated by p<0.05 (two tailed). RESULTS: The study sample was composed of 24 ATTRS77Y patients. The mean patient age was 58.4±12.4 years. None of the patients presented with amyloid deposits in the anterior chamber, secondary glaucoma or vitreous amyloidosis. Retinal angiopathy was observed in four patients, complicated with retinal ischaemia in one patient. Conjunctival lymphangiectasia (CL) was detected in 13 patients (54%), associated with perilymphatic amyloid deposits. The presence of CL was statistically associated with more severe neurological disease (NIS=43.3±31.9 vs 18.9±20.4; PND=2.6±1.0 vs 1.4±0.7 in patients with and without CL, respectively; both p<0.05) and amyloid cardiomyopathy (p=0.002). CONCLUSION: In ATTRS77Y patients, CL is common and could serve as a potential biomarker for severe systemic disease. There were neither anterior chamber deposits, secondary glaucoma nor vitreous deposits in ATTRS77Y patients.

Efficacy of a Topical Heparan Sulfate Mimetic Polymer on Ocular Surface Discomfort in Patients with Cogan's Epithelial Basement Membrane Dystrophy.

Purpose: Treatment of persistent ocular discomfort in patients with Cogan's epithelial basement membrane dystrophy (EBMD) is a challenge for ophthalmologists. This study aimed to determine the efficacy of a topical heparan sulfate mimetic polymer (HSMP) in reducing ocular discomfort in EBMD patients. Methods: This retrospective, noninterventional study included 22 consecutive patients in 3 tertiary ophthalmological units with spontaneous, recurrent, acute ocular pain, resistant to various topical lubricants. After EBMD diagnosis, HSMP treatment was initiated while lubricating eye drops were continued. The main study outcome was the change in ocular discomfort assessed using the ocular surface disease index (OSDI) from initiation of treatment to last follow-up visit. Results: The mean OSDI decreased from 46.7 ± 22.3 to 31.6 ± 17.4 (P < 0.001) at first visit and 32.5 ± 17.9 (P < 0.01) at last visit. The rate of patients with severe ocular surface disease (OSDI >33) decreased from 68.2% to 36.4% at first visit and 42.9% at last visit. After a median follow-up of 8.5 months, 7 (31.8%) patients discontinued the HSMP treatment due to a marked improvement in ocular surface comfort and no recurrence of ocular pain, 5 (22.7%) due to lack of efficacy, and 1 (4.5%) due to an ocular adverse event (not treatment related). Eight patients continued treatment after the last visit and 1 patient was lost to follow-up. Globally, HSMP prevented acute painful episodes in 11 (61.1%) of 18 patients followed for ∼4 months. Conclusions: Topical HSMP may be an option for alleviating ocular discomfort in patients with EBMD resistant to standard symptomatic treatments.

Prevalence and Clinical Patterns of Ocular Complications Associated With Anti-PD-1/PD-L1 Anticancer Immunotherapy.

PURPOSE: Immune checkpoint inhibitors (ICI) targeting the programmed cell death protein 1 (PD-1), or its ligand PD-L1, are the mainstay of metastatic cancer treatment. Patients receiving these treatments may develop immune-related adverse events (irAEs). This study aimed to estimate the prevalence and describe the clinical patterns of moderate-to-severe ocular irAEs-associated with anti-PD-(L)1 treatment. DESIGN: Prospective case series. METHODS: This study included patients recruited via (1) a single-center prospective cohort and (2) a national pharmacovigilance registry between June 2014 and March 2018, and focused on patients with moderate-to-severe ocular irAEs following anti-PD-(L)1. All patients underwent a comprehensive ophthalmologic assessment. The main outcome measure was the prevalence of moderate-to-severe ocular irAEs. RESULTS: Of a total of 745 patients included in the prospective cohort, 3 developed moderate-to-severe ocular irAEs, providing a prevalence of 0.4% and an incidence of 0.7 per 1000 patient-months of treatment. An additional 5 cases of moderate-to-severe ocular irAEs were reported through the national registry. From these 8 patients, 5 presented with intraocular inflammation, 2 with ocular surface disease, and 1 with orbital myopathy. Five patients (62.5%) experienced additional extraophthalmologic irAEs. Ocular irAEs led to permanent discontinuation of anti-PD-(L)1 in 4 patients. Treatment by local and/or systemic corticosteroids allowed resolution or control of the ocular symptoms in 7 of 8 patients. CONCLUSION: Although uncommon, anti-PD-(L)1-associated ocular complications may be sight-threatening and lead to discontinuation of anti-PD-(L)1 treatments. Patients complaining of eye problems while receiving ICI treatment should immediately be seen by an ophthalmologist.
