[Management of ocular toxoplasmosis in France: Results of a modified Delphi study]. / Prise en charge de la toxoplasmose oculaire en France : résultats d'une étude Delphi modifiée.

OBJECTIVE: To evaluate diagnostic and therapeutic practices and then establish a consensus on the management of ocular toxoplasmosis in France through a Delphi study. MATERIALS AND METHODS: Twenty-three French experts in ocular toxoplasmosis were invited to respond to a modified Delphi study conducted online, in the form of two questionnaires, in an attempt to establish a consensus on the diagnosis and management of this pathology. The threshold for identical responses to reach consensus was set at 70 %. RESULTS: The responses of 19 experts out of the 23 selected were obtained on the first questionnaire and 16 experts on the second. The main elements agreed upon by the experts were to treat patients with a decrease in visual acuity or an infectious focus within the posterior pole, to treat peripheral lesions only in the presence of significant inflammation, the prescription of first-line treatment with pyrimethamine-azithromycin, the use of corticosteroid therapy after a period of 24 to 48hours, the prophylaxis of frequent recurrences (more than 2 episodes per year) with trimethoprim-sulfamethoxazole as well as the implementation of prophylactic treatment of recurrences in immunocompromised patients. On the other hand, no consensus emerged with regard to the examinations to be carried out for the etiological diagnosis (anterior chamber paracentesis, fluorescein angiography, serology, etc.), second-line treatment (in the case of failure of first-line treatment), or treatment of peripheral foci. CONCLUSION: This study lays the foundations for possible randomized scientific studies to be conducted to clarify the management of ocular toxoplasmosis, on the one hand to confirm consensual clinical practices and on the other hand to guide practices for which no formal consensus has been demonstrated.

[Retinal vascular network: Changes with aging and systemic vascular disease (cardiac and cerebral)]. / Caractéristiques vasculaires rétiniennes : modifications lors du vieillissement et en pathologie vasculaire systémique (cardiaque et cérébrale).

For over 10 years, the description of the retinal microvascular network has benefited from the development of new imaging techniques. Automated retinal image analysis software, as well as OCT angiography (OCT-A), are able to highlight subtle, early changes in the retinal vascular network thanks to a large amount of microvascular quantitative data. The challenge of current research is to demonstrate the association between these microvascular changes, the systemic vascular aging process, and cerebrovascular and cardiovascular disease. Indeed, a pathophysiological continuum exists between retinal microvascular changes and systemic vascular diseases. In the Montrachet study, we found that a suboptimal retinal vascular network, as identified by the Singapore I Vessel Assessment (SIVA) software, was significantly associated with treated diabetes and an increased risk of cardiovascular mortality. In addition, we supplemented our research on the retinal vascular network with the use of OCT-A. In the EYE-MI study, we showed the potential role of quantitative characterization of the retinal microvascular network by OCT-A in order to assess the cardiovascular risk profile of patients with a history of myocardial infarction. A high AHA (American Heart Association) risk score was associated with low retinal vascular density independently of hemodynamic changes. Thus, a better understanding of the association between the retinal microvasculature and macrovascular disease might make its use conceivable for early identification of at-risk patients and to suggest a personalized program of preventative care. The retinal vascular network could therefore represent an indicator of systemic vascular disease as well as an interesting predictive biomarker for vascular events.

[Vision screening for children: Recommended practices from AFSOP]. / Le dépistage visuel chez l'enfant : les recommandations de l'Association Francophone de Strabologie et d'Ophtalmologie Pédiatrique (AFSOP).

In light of the international literature, a workgroup of experts from the AFSOP met in February 2019 to formulate updated recommendations for visual screening in children. An ophthalmologic examination during the first month of life is recommended for children at risk of developing infantile organic amblyopia. An ophthalmologic examination including cycloplegic refraction between 12 and 15 months of age is recommended for children at risk of developing functional amblyopia. At any age, a prompt ophthalmologic examination is recommended for a child suspected of functional or organic ocular pathology. In children without risk factors or warning signs, a systematic orthoptic screening examination is recommended during the third year of life, including a monocular visual acuity test, a cover-test and a refraction by photoscreener. The child is referred to the ophthalmologist only in the case of an abnormal screening result, according to the following criteria: visual acuity <5/10, or >1 difference between eyes, abnormal cover test, photodetection refraction values <-3D or>+2.5D for the sphere,>1.5D for astigmatism and>1D for anisometropia. Finally, we review normal childhood refractive errors as a function of age as well as the correct use of photo screening devices.

Management of ocular involvement in the acute phase of Stevens-Johnson syndrome and toxic epidermal necrolysis: french national audit of practices, literature review, and consensus agreement.

Stevens-Johnson Syndrome (SJS) and toxic epidermal necrolysis (TEN) can lead to severe ophthalmologic sequelae. The main risk factor is the severity of the initial ocular involvement. There are no recommendations for ocular management during acute phase.We conducted a national audit of current practice in the 11 sites of the French reference center for toxic bullous dermatoses and a review of the literature to establish therapeutic consensus guidelines. We sent a questionnaire on ocular management practices in SJS/ TEN during acute phase to ophthalmologists and dermatologists. The survey focused on ophthalmologist opinion, pseudomembrane removal, topical ocular treatment (i.e. corticosteroids, antibiotics, antiseptics, artificial tear eye drops, vitamin A ointment application), amniotic membrane transplantation, symblepharon ring use, and systemic corticosteroid therapy for ophthalmologic indication. Nine of 11 centers responded. All requested prompt ophthalmologist consultation. The majority performed pseudomembrane removal, used artificial tears, and vitamin A ointment (8/9, 90%). Combined antibiotic-corticosteroid or corticosteroid eye drops were used in 6 centers (67%), antibiotics alone and antiseptics in 3 centers (33%). Symblepharon ring was used in 5 centers (55%) if necessary. Amniotic membrane transplantation was never performed systematically and only according to the clinical course. Systemic corticosteroid therapy was occasionally used (3/9, 33%) and discussed on a case-by-case basis.The literature about ocular management practice in SJS/ TEN during acute phase is relatively poor. The role of specific treatments such as local or systemic corticosteroid therapy is not consensual. The use of preservatives, often present in eye drops and deleterious to the ocular surface, is to be restricted. Early amniotic membrane transplantation seems to be promising.

Acute retinal arterial ischaemia: silent brain infarcts prevalence and short-term recurrence.

BACKGROUND AND PURPOSE: The purpose was to evaluate, in a consecutive series of patients with isolated acute retinal ischaemia, the proportion of patients with acute silent brain infarcts (SBIs) on diffusion-weighted imaging (DWI) and to assess risk of recurrence within 3 months. METHODS: In all, 103 consecutive patients with isolated acute retinal ischaemia (central retinal artery occlusion, branch retinal artery occlusion or transient monocular vision loss) were included between January 2015 and December 2016. They all had cerebral magnetic resonance imaging including DWI as well as a standardized aetiological workup and 3 months of follow-up. The presence of DWI-positive cerebral lesions was recorded. Main clinical and radiological characteristics between DWI-positive and DWI-negative patients were compared. RESULTS: Of the 103 patients (including 42 transient monocular vision loss), 20 (19.5%) had SBIs on DWI, which were ipsilateral to the acute retinal ischaemia in 30% and involved different and/or multiple vascular territories in 70% of cases. Ipsilateral carotid stenosis and occlusion were respectively identified in 17 and eight patients whereas cardioaortic embolism was found in 19 patients. Overall, patients with and without acute SBIs were comparable. The topography of SBIs was related to the aetiology of the acute retinal ischaemia. At 3 months of follow-up, one patient suffered from ischaemic stroke and five had recurrent retinal ischaemia. CONCLUSIONS: Irrespective of the baseline characteristics of the patients, SBIs are present in about 20% of patients with isolated acute retinal ischaemia and may be of interest in the aetiological workup. Overall risk of recurrence is low, favoured by rapid aetiological workup and appropriate treatment.

[Validation of the 13-30ARAMAV assessment, a new quality of life and autonomy questionnaire adapted to visually impaired patients]. / Validation du bilan 13­30ARAMAV, un nouveau questionnaire de qualité de vie et d'autonomie adapté aux patients déficients visuels.

PURPOSE: To evaluate the ARAMAV 13-30 questionnaire, a new autonomy and quality of life questionnaire developed for visually impaired patients. METHODS: We carried out a single-center prospective study at the ARAMAV institute in collaboration with the University Hospital of Nîmes. The patients included were admitted for low vision rehabilitation. Each patient received an occupational therapy assessment, the Short Forms 36 (SF36) quality of life questionnaire and the ARAMAV 13-30 questionnaire at the start and at the end of rehabilitation. We verified the reproducibility, the sensitivity to change, and internal and external consistency of the questionnaire. RESULTS: We included 231 patients over a period of 4 years. All the patients were blind or visually impaired. We observed excellent intra- and interuser reproducibility of the questionnaire, with a Lin coefficient>0.9 (0.99 and 0.91, respectively). By comparing the variations of the different scores between before and after low vision rehabilitation, we observed excellent sensitivity to change for both the autonomy and quality of life portions of the questionnaire. Finally, we observed excellent internal and external consistency. CONCLUSION: We therefore propose the ARAMAV 13-30 questionnaire as a new tool in evaluating autonomy and quality of life specifically in visually impaired patients, which may also be used to assess the effect of low vision rehabilitation.

[Can Big Data change our practices?] / Le Big Data peut-il changer nos pratiques ?

The European Medicines Agency has defined Big Data by the "3 V's": Volume, Velocity and Variety. These large databases allow access to real life data on patient care. They are particularly suited for studies of adverse events and pharmacoepidemiology. Deep learning is a collection of algorithms used in machine learning, used to model high-level abstractions in data using model architectures, which are composed of multiple nonlinear transformations. This article shows how Big Data and Deep Learning can help in ophthalmology, pointing out their advantages and disadvantages. A literature review is presented in this article illustrating the uses of Deep Learning in ophthalmology.

Sensory loss and suicide ideation in older adults: findings from the Three-City cohort study.

ABSTRACTObjectives:To examine the longitudinal risk of vision loss (VL) or hearing loss (HL) for experiencing suicidal ideation in older adults. DESIGN: The Three-City study, examining data from three waves of follow-up (2006-2008, 2008-2010, and 2010-2012). SETTING: Community-dwelling older French adults. PARTICIPANTS: N = 5,438 adults aged 73 years and over. MEASUREMENTS: Suicidality was assessed by the Mini-International Neuropsychiatric Interview, Major Depressive Disorder module. Mild VL was defined as Parinaud of 3 or 4 and severe VL as Parinaud >4. Mild HL was self-reported as difficulty understanding a conversation and severe HL as inability to understand a conversation. RESULTS: Severe VL was associated with an increased risk of suicidal ideation at baseline (OR = 1.59, 95% CIs = 1.06-2.38) and over five years (OR = 1.65, 95% CIs = 1.05-2.59). Mild and severe HL were associated with an increased risk of suicidal ideation, both at baseline (OR = 1.29, 95% CIs = 1.03-1.63; OR = 1.78, 95% CIs = 1.32-2.40) and over five years (OR = 1.47, 95% CIs = 1.17-1.85; OR = 1.97, 95% CIs = 1.44-2.70). CONCLUSION: Sensory losses in late life pose a risk for suicidal ideation. Suicidality requires better assessment and intervention in this population.

Bidirectional associations of vision and hearing loss with anxiety: prospective findings from the Three-City Study.

OBJECTIVE: the aim of this study was to examine the bidirectional association of vision loss (VL) and hearing loss (HL) with anxiety over a 12-year period. DESIGN: this was a prospective population-based study. SETTING: community-dwelling French adults. PARTICIPANTS: the study included 3,928 adults aged 65 and above from the Three-City study. METHODS: the relationships of VL, as assessed by near visual acuity and self-reported HL to a diagnosis of generalised anxiety disorder (GAD) were assessed over 12 years. A further objective was to explore whether sensory loss has a differential relationship with GAD than with anxiety symptoms, assessed by the Spielberger's State-Trait Anxiety Inventory. RESULTS: at baseline, HL [odds ratio (OR) = 1.41, 95% confidence interval (CI) 1.02-1.96, P = 0.04], but not mild or moderate to severe VL, was associated with self-reported anxiety symptoms (OR = 1.07 95% CI 0.63-1.83, P = 0.80; OR = 0.66 95% CI 0.12-2.22, P = 0.50, respectively). Neither vision nor HL was significantly associated with incident GAD. Baseline GAD was related to increased risk of incident HL (OR = 1.17, 95% CI 1.07-1.28, P < 0.001), but not mild or moderate to severe vision loss (OR = 1.01, 95% CI 0.96-1.06, P = 0.81; OR = 0.97, 95% CI 0.89-1.05, P = 0.45, respectively). CONCLUSIONS: increased anxiety symptoms were observed in older adults with HL, whereas we found no evidence for an association between VL and anxiety. Anxiety was prospectively associated with increased risk of reporting HL. Improved detection of anxiety in older adults with HL may improve quality of life.

[Acute diplopia after the age of 50; always look for giant cell arteritis]. / Diplopie brutale après l'âge de 50 ans, toujours rechercher une maladie de Horton.

Although giant cell arteritis (GCA) is a rare cause of ophthalmoplegia, swift diagnosis and treatment are necessary to avoid other complications. We report here a case of GCA in a 59-year-old woman with a history of hypertension and thyroid lobectomy. Diagnosis resulted from binocular diplopia, although classical GCA symptoms had been present a few days before. Oral corticotherapy led to a rapid disappearance of headaches and normal ocular motility in 1 month. We discuss the ophthalmological signs of the disease and the place of temporal artery biopsy and treatment.
