RESUMO

OBJECTIVE: Cerebral amyloid angiopathy-related inflammation (CAA-ri) is a rare manifestation related to CAA, thought to be more severe. We aimed to compare the clinical and radiological outcomes of CAA-ri and non-inflammatory CAA. MATERIALS AND METHODS: We retrospectively included all patients with CAA-ri from 13 French centers. We constituted a sex- and age-matched control cohort with non-inflammatory CAA and similar disease duration. Survival, autonomy and cognitive evolution were compared after logistic regression. Cerebral microbleeds (CMB), intracerebral hemorrhage, cortical superficial siderosis and hippocampal atrophy were analyzed as well as CSF biomarker profile and APOE genotype when available. Outcomes were compared using Kaplan-Meier curves and log-rank tests. RESULTS: Data from 48 CAA-ri patients including 28 already reported and 20 new patients were analyzed. Over a mean of 3.1 years, 11 patients died (22.9%) and 18 (37.5%) relapsed. CAA-ri patients were more frequently institutionalized than non-inflammatory CAA patients (30% vs 8.3%, p < 0.001); mortality rates remained similar. MMSE and modified Rankin scale scores showed greater severity in CAA-ri at last follow-up. MRI showed a higher number of CMB at baseline and last follow-up in CAA-ri (p < 0.001 and p = 0.004, respectively). CSF showed lower baseline levels of Aß42 in CAA-ri than non-inflammatory CAA (373.3 pg/ml vs 490.8 pg/ml, p = 0.05). CAA-ri patients more likely carried at least one APOE ε4 allele (76% vs 37.5%, adjusted p = 0.05) particularly as homozygous status (56% vs 6.2%, p < 0.001). INTERPRETATION: CAA-ri appears to be more severe than non-inflammatory CAA with a significant loss of autonomy and global higher amyloid burden, shown by more CMB and a distinct CSF profile. This burden may be partially promoted by ε4 allele.

RESUMO

PURPOSE: While endothelial keratoplasty has become the standard treatment for Fuchs dystrophy, the strategy for first-line surgery in patients with associated cataract is still debated. The purpose of this study was to evaluate the surgical outcomes of eyes with Fuchs endothelial corneal dystrophy (FECD) undergoing phacoemulsification alone, to ascertain preoperative factors that predict the need for endothelial keratoplasty (EK). METHODS: Single-center retrospective study. Cataract surgery alone was performed in 64 eyes of 50 patients with FECD. This decision was made if the patient did not have morning blur, the central corneal thickness (CCT) was below 630 microns, and endothelial cells were visible in the periphery. RESULTS: Mean follow-up was 21 months (range 5-55 months). The mean preoperative CCT was 571±43µm. 6 months after surgery, it was 584±52µm (P=0.12). During follow-up, 14 eyes (22%) required an EK because of poor visual outcome after cataract surgery alone. Mean pre-operative CCT of these eyes (595±23µm) was significantly higher than eyes that did not require EK during follow-up (564±45µm, P=0.022). Over 570 microns, 34% of eyes required an endothelial keratoplasty after the cataract surgery alone. CONCLUSIONS: CCT below 630µm associated with the absence of morning blur are preoperative criteria allowing 78.1% eyes with FECD to obtain good visual outcomes after cataract surgery alone. In these eyes, EK can therefore be avoided while ensuring good results.

RESUMO

INTRODUCTION: A fire at the Lubrizol chemical factory in Rouen on September 26, 2019 generated a huge column of smoke directed northeast toward the city. As the eye might be particularly affected by the smoke and other toxic emissions from the fire, we assessed the impact of this industrial and ecological disaster on irritative eye surface disease in the week following the accident. MATERIALS AND METHODS: We retrospectively collected the medical data of the patients who presented to the Ophthalmology Emergency Department (OED) of Rouen University Hospital (the only OED open during the days following the accident) during the week following the fire (W1). We compared these data with those of patients who presented during the week before the fire (W-1). We also collected data on patients presenting to the ED in general during W-1 and W1, including the number of visits directly related to the fire. RESULTS: 361 patients presented to the OED during W1 following the fire, compared with 384 in W-1. Of these patients, 83 (23%) had ocular surface disease in W1, versus 76 (20%) in W-1. Conjunctivitis was found in 54 patients in W1 (39 viral, 9 allergic, 6 undetermined) versus 44 in W-1 (27 viral, 12 allergic, 5 undetermined). A dry irritative syndrome was present in 29 patients in W1 versus 32 in W-1. Only 4 patients directly attributed their symptoms to the fire: 2 viral conjunctivitis, 1 allergic conjunctivitis and 1 worried patient (at D2, D5, D7 and D7 following the fire respectively). DISCUSSION: The number of emergency eye consultations did not change in the week following the Lubrizol factory fire (except for a decrease the day of the accident, related to the lock-down). There was a higher number of consultations in W1 for conjunctivitis, mostly viral in appearance and probably not directly related to the fire. The number of consultations for dry irritative syndrome was comparable between the two periods. Despite major media coverage of the event at the national level and a very high level of concern among the population, the fire does not seem to have had an effect on OED activity at Rouen University Hospital, nor on general ED visits. The stay-at-home order on the first day may have had a protective effect, avoiding direct exposure to smoke. The long-term consequences of the soot deposits on the ground as the smoke cloud passed over remain undetermined and are under surveillance. A review of the literature on the ocular consequences of industrial accidents is presented. CONCLUSION: The Ophthalmology Emergency Department did not record increased activity in the week following the Lubrizol Rouen fire, and ocular surface disease did not give rise to more consultations than the week before the fire. This suggests that there was no or minimal immediate ocular toxicity of the smoke from the fire.

RESUMO

INTRODUCTION: Meibomian gland dysfunction (MGD) is the most common cause of dry eye syndrome. The goal of this study was to evaluate the efficacy of combined intense pulsed light (IPL) and low-level light therapy (LLLT) in symptomatic MGD. MATERIALS AND METHODS: This retrospective study analyzed data from 30 patients with MGD causing dry eye symptoms not relieved by medical therapy and managed with combined IPL and LLLT. The primary endpoint was the Ocular Score Disease Index (OSDI) score at 1 month and 1 year. Secondary endpoints were visual acuity, intraocular pressure, tear film break-up time, Schirmer's test, Oxford score, and infrared meibographic score at 1 month after the conclusion of treatment. RESULTS: The mean OSDI score decreased from 43±19 to 17±12 (1 month; p<0.0001) and then to 29±11 (12 months; p=0.013); 63% of patients were meibographic grade 2 before versus 7% after treatment (range, 1-4) (p=0.009); 75% of patients were Oxford grade 1 before versus 41% after treatment (p=0.004) (range, 1-3). No significant difference in the other secondary endpoints was noted. CONCLUSION: Over time, IPL therapy in combination with LLLT appears to improve patients with symptomatic MGD resistant to medical therapy.

RESUMO

PURPOSE: Descemet membrane endothelial keratoplasty (DMEK) combined with cataract extraction and intraocular lens insertion (new triple procedure) limits postoperative refractive errors. The objective of this study was to assess refractive accuracy after DMEK combined with cataract extraction and intraocular lens implantation. SETTING: Four university hospitals (Rouen, Paris, Reims, Grenoble). DESIGN: This retrospective multicenter study included patients with symptomatic corneal endothelial decompensation and cataract. METHODS: The primary outcome was the difference between the target spherical equivalent and postoperative refraction at months 2 and 6. Secondary outcomes were visual acuity, keratometry, pachymetry and endothelial cell density. RESULTS: A total of 130 eyes of 111 patients (mean age 66.2 years) were included (94% with Fuchs' endothelial dystrophy). For a mean refractive target set at -0.50 (±0.57) D, the mean (95% CI) refractive error was hyperopia of +0.49 (0.314; 0.664) D at 2 months and +0.46 (0.299; 0.619) D at 6 months. Best corrected distance visual acuity was improved in all patients: from 0.49 (±0.3) logMAR to 0.14 (±0.14) logMAR at 2 months and 0.05 (±0.1) logMAR at 6 months. Mean corneal thickness decreased from 621.6 (±37.6) µm to 515.2 (±42.6) µm at 2 months and 539.0 (±39.0) µm at 6 months. CONCLUSIONS: Good refractive accuracy was obtained after the new triple procedure with DMEK. Hyperopic shift is common after triple procedures, and its persistence should be evaluated in future studies in order to anticipate a change in its value to optimize intraocular lens power calculation.

RESUMO

OBJECTIVES: Since the 2000s, there has been an increase in prevalence of neurosyphilis (NS) and ocular syphilis (OS). As data about symptomatic NS/OS is limited, this study aims to assess the characteristics of symptomatic NS/OS, according to HIV status. METHODS: We compared the clinical and biological presentation of early symptomatic NS/OS and its outcome in HIV-positive and HIV-negative patients. RESULTS: Ninety-six patients (93% men, 49% HIV-positive) were included from 2000 to 2016 in two centers, with 67 (69%) having OS, 15 (16%) NS, and 14 (14%) both. HIV-positive patients were younger (P=0.006) and more likely to be males having sex with males (P=0.00048) or to have a history of syphilis (P=0.01). Among 81 OS, there were 43 posterior uveitis (57%), and bilateral involvement was more common in HIV-positive patients (62% versus 38%, P=0.045). Among 29 NS there were 21 cases of cranial nerve involvement (72%), seven meningitis (24%) and 11 paresthesia (38%). Involvement of the VIIIth cranial nerve was the most common (16 cases). Treponemal tests were more commonly found positive in cerebrospinal fluid in HIV-positive patients (88% versus 76%, P=0.04). Visual acuity (VA) always improved after treatment (initial VA logMAR 0.8±0.8 versus 0.1±0.1 at 3 months), but 32% and 18% of the patients still had neurological or ocular impairment respectively six and 12 months after treatment. Non-treponemal serological reversion was observed in 43/50 patients (88%) at six months. CONCLUSION: HIV infection has no consequence on the outcome of NS and OS. Sequelae are common, emphasizing the importance of prevention, and screening, and questioning enhanced treatment.

RESUMO

PURPOSE: To study the efficacy, stability, safety and predictability of small incision lenticule extraction (SMILE) at 1 day and 3 months postoperatively for moderate and high myopic astigmatism. To describe a simple and convenient method for detection and manual compensation of cyclotorsion during the procedure. METHODS: In this retrospective study, a total of 164 eyes from 114 patients over 20 years of age with at least 1.5 diopters (D) of myopic astigmatism were treated by SMILE. Any cyclotorsion was manually compensated by gently rotating the cone to align the horizontal marks on the cornea to the 0° to 180° axis of the reticule after activating the suction. RESULTS: The mean preoperative spherical equivalent (SE) was -5.3±2.01 D, and the mean cylinder was -2.01±0.67 D. Three months after surgery, a total of 87% of eyes were within±0.50 D of attempted post-operative SE, and 98% of eyes were within±1.00 D. Overall, the predictability of cylinder correction was excellent, with 96.3% of eyes within±1.00 D of attempted post-operative cylinder. The mean postoperative cylinder at three months was -0.3±0.39 D. We noted a slight undercorrection with treatment of high cylinder. However, 82% of eyes achieved postoperative refractive astigmatism less than 0.5 D. 91% of eyes achieved uncorrected distance visual acuity (UDVA) equal to or better than 8/10. 22% of eyes gained one line of visual acuity. CONCLUSION: SMILE is a predictable and safe technique for the surgical correction of astigmatism. Manual compensation may be an effective approach to improve astigmatic outcomes of SMILE, especially in moderate and high astigmatism.

RESUMO

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.

RESUMO

INTRODUCTION: Uveitis-Glaucoma-Hyphema syndrome (UGH) is caused by mechanical chafing of anterior segment structures by an intraocular lens, especially an anterior chamber lens. The objective of this study was to characterise the clinical course and risk factors of UGH syndrome at a time when posterior chamber implantation is the gold standard. PATIENTS AND METHODS: This was a retrospective study of 30 cases of UGH syndrome managed between January 2014 and September 2018. Data from the initial clinical examination, the type of implant involved and the clinical management were analysed. RESULTS: Thirty eyes of 28 patients were included. Intra ocular lenses were iris-sutured (15/30, 50 %), in the bag (6/30, 20 %), scleral-fixated (4/30, 13.3 %), in the ciliary sulcus (3/30,10 %) or "in and out" (2/30, 6.7 %). Initial management was medical (18 eyes) or surgical (12 eyes). Surgical procedures were explantation (n=4), IOL repositioning (n=7) or trabeculectomy (n=1). Recurrences occurred with medical treatment (9/18), but not in the surgical group (p=0.02). Ocular hypertension became chronic in 19 cases out of 30 (63.3 %). CONCLUSION: UGH syndrome can be caused by any type of pseudophakic lens. An intraocular lens in the bag should not rule out the diagnosis. Despite the decreasing popularity of anterior chamber intraocular lens implantation, UGH syndrome remains a current condition and must be recognised in order to adapt therapeutic management.

RESUMO

CONTEXT: Cerebrospinal fluid (CSF) biomarkers are valuable tools for the diagnosis of neurological diseases. We aimed to investigate within a retrospective multicentric study the final diagnosis associated with very high CSF Tau levels and to identify patterns of biomarkers that would differentiate them in clinical practice, to help clinical biologists into physicians' counseling. PATIENTS AND METHODS: Within the national multicentric network ePLM, we included 1743 patients from January 1, 2008, to December 31, 2013, with CSF biomarkers assayed by the same Innotest assays (protein Tau, phospho-Tau [pTau], and Aß 1-42). We identified 205 patients with protein Tau concentration higher than 1200 pg/mL and final diagnosis. RESULTS: Among those patients, 105 (51.2%) were suffering from Alzheimer's disease, 37 (18%) from sporadic Creuztfeldt-Jakob disease, and 63 (30.7%) from other neurological diseases including paraneoplastic/ central nervous system tumor, frontotemporal dementia, other diagnoses, amyloid angiopathy, Lewy body dementia, and infections of the central nervous system. Phospho-Tau, Aß1-42 and Aß1-42/pTau values differed significantly between the three groups of patients (p < .001). An Aß1-42/pTau ratio between 4.7 and 9.7 was suggestive of other neurological diseases (threshold in AD: 8.3). CSF 14-3-3 was useful to discriminate Alzheimer's disease from Creuztfeldt-Jakob disease in case of Aß1-42 concentrations <550 pg/mL or pTau>60 pg/mL. CONCLUSION: This work emphasizes the interest of a well-thought-out interpretation of CSF biomarkers in neurological diseases, particularly in the case of high Tau protein concentrations in the CSF.

RESUMO

INTRODUCTION: Atopic keratoconjunctivitis is associated with eyelid eczema. It may require the use of local corticosteroids which if prolonged can be a source of ocular complications. Tacrolimus is an immunosuppressant used in cutaneous application in atopic dermatitis. The aim of this study was to measure the efficacy and tolerance of tacrolimus 0.1% ointment in palpebral application in atopic keratoconjunctivitis. PATIENTS AND METHODS: This retrospective, single-center study was conducted between June 2014 and February 2017. Patients with atopic keratoconjunctivitis not controlled by first-line medical treatments were included. The primary endpoint was the evolution of functional signs as assessed by the NEI-VFQ25 and OSDI quality of life scores. Secondary endpoints were visual acuity and local corticosteroid use. RESULTS: Among the 18 patients included, the mean age was 37.9±16.8 years. The first follow-up visit was on average 68.3±55.3 days after initiation of treatment. The NEI-VFQ25 score was significantly improved for seven of its sub-scores (P<0.05) and the mean OSDI decreased significantly from 52.3±26.2 to 22.0±27.0 (P<0.001) showing a decrease in eye discomfort. A significant reduction was observed in the number of patients using local corticosteroids. There was no significant change in visual acuity. CONCLUSION: Tacrolimus ointment 0.1% in palpebral application appears to be an effective treatment for the management of atopic keratoconjunctivitis.

RESUMO

INTRODUCTION: Corneal tattooing is a noninvasive technique which appears relatively well-tolerated in the medium term. We report the cases of 3 patients with a significant change in the color of their tattoos performed over 5 years previously. PATIENTS AND METHODS: Three patients with a history of intracorneal tattooing several years previously were studied because of a significant change from their initial color. Each patient's file was reviewed with analysis of slit lamp photographs, OCT and specular microscopy. RESULTS: All three patients experienced a significant color change in their tattoos between 5 and 6 years after surgery. The color had changed to golden-brown. DISCUSSION: Retrospective analysis of the components of the tattoo ink found the presence of iron in the black pigment. We believe that pigments composed of iron oxide are transformed into golden-brown ferric iron oxide in the presence of oxygen in the aqueous environment. The presence of moderate corneal edema in these three cases of multioperated patients could explain, in these specific cases, the occurrence of oxidation typically not described. CONCLUSION: Corneal tattooing remains a simple and very interesting technique when partial or total absence of iris causes significant photophobia. However, the significant changes in color that we report more than 5 years later suggest omitting iron from the dyes used for the cornea and limiting its use in cases of limited endothelial prognosis. A long-term evaluation of corneal tattoos appears necessary.

RESUMO

The corneal limbus is a privileged region on the border between two quite different microenvironments, where corneal epithelial stem cells, numerous melanocytes, and antigen-presenting cells are all concentrated within a richly vascularized and innervated stroma. This situation within the ocular surface confers on it the key functions of barrier, epithelial renewal and defense of the cornea. As an immunological crossroads and since the corneoscleral limbus is directly exposed to external insults such as caustic agents, ultraviolet radiation, microbial agents, and allergens, it is the potential site of many tumoral, degenerative or inflammatory pathologies and may progress under certain conditions to limbal stem cell deficiency.
