RESUMO
PURPOSE: To assess risk factors of rejection after penetrating keratoplasty (PKP). METHODS: This retrospective monocentric study assessed risk factors for rejection in patients who underwent PKP at Montpellier University Hospital between June 2005 and September 2018. Graft and donor data were obtained from our tissue bank in Montpellier. Clinical data of recipients were recorded from medical files. Survival was estimated by the Kaplan-Meir method. Potential risk factors of rejection were assessed by multivariate Cox proportional hazards analysis, estimating hazard ratios (HR) and 95% confidence intervals (CI). RESULTS: Among the 316 consecutive patients (59% male, mean SD] age 52 [17]), 360 eyes underwent PKP. Indications for PKP were bullous keratopathy (27%), infectious keratitis (20%), and keratoconus (15%). The median follow-up was 44 months (IQR 22-73). The overall graft survival and irreversible rejection rate at 5 years were 70% and 29%, respectively. Factors associated with risk of rejection were prior indication for graft rejection (SHR [CI 95%] = 7.8 [2.6-23.1]), trauma (SHR [CI 95%] = 3.6 [1.1-11.7]), and infectious keratitis (SHR [CI 95%] = 2.7 [1.2-11.1]), history of corneal neovascularization (SHR [CI 95%] = 2.1 [1.2-3.8]), hypertonia (SHR [CI 95%] = 2.8 [1.8-4.3]), and mixed sex matching (SHR [CI 95%] = 2.0 [1.01-4.0]). CONCLUSION: The significant risk factors of graft rejection after PKP found in this study agree with those from major international cohorts: prior indication for graft rejection, history of neovascularization and high intraocular pressure. Sex matching donor-recipient is a most recent parameter in the literature confirmed by the present analysis. TRIAL REGISTRATION: ClinicalTrials.gov Identifier: NCT04791696.

INTRODUCTION: The aims of this study were to study ocular biometric data and their association with age and sex in a population of cataract surgery candidates and to assess the proportion of inhomogeneous eyes and the ratio anterior segment (AS) to axial length (AL). Multicentric cross-sectional analysis was conducted between April 2008 and May 2021 in public and private ophthalmic institutions in Montpellier, France. Individuals ≥40 years old who underwent ocular biometry before cataract surgery were included. METHODS: Right phakic eyes were included. Ocular biometrics were measured by using the Lenstar LS900 device. We defined AS as anterior chamber depth (ACD) plus lens thickness (LT) and calculated the ratio of AS to AL. We defined inhomogeneous eyes as those with deep AS (≥4th quartile) and short AL (≤1st quartile) (AS+) or with short AS and high AL (AL+). RESULTS: We included 11,650 individuals (11,650 eyes) (mean [SD] age 71.64 [10.50] years; 54.51% women). Older age was associated with shorter AL (p < 0.01), shallower ACD (p < 0.01), thinner central corneal thickness (p < 0.01), and larger LT (p < 0.001). Women had shorter AL, shallower ACD, and thinner central corneal thickness than men (p < 0.001). In total, 778 (6.68%) eyes were inhomogeneous (3.22% AS+ and 3.46% AL+), for a mean (SD) AS/AL ratio of 0.36 (0.01) and 0.28 (0.01), respectively, as compared with 0.32 (0.02) for homogeneous eyes (p < 0.001). CONCLUSION: The AS/AL ratio could be useful to screen inhomogeneous eyes before cataract surgery and justify the use of new generation formulas in these eyes to avoid the risk of refractive error.
RESUMO
AIMS: While major vascular complications (MVC) remains an issue after Transfemoral (TF) transcatheter aortic valve replacement (TAVR), we compared outcomes in TF versus transcarotid (TC) approaches in patients with complex vascular anatomy. METHODS AND RESULTS: Among patients undergoing TAVR in our center between 2015 and 2018, we evaluated patients with complex vascular anatomy defined on CT scan as: (a) iliofemoral diameter between 5.5 and 6 mm or <6.5 mm with severe calcifications or tortuosity AND/OR (b) abdominal aorta pathology. The primary endpoint included access failure, mortality, MVC, major bleeding and stroke at 1-month. Among 483 patients, 131 (31.2%) with complex vascular anatomy underwent TF (n = 51;39.2%) or TC (n = 80;60.8%) TAVR. The mean age was 81.7 ± 6.9. TC group had higher STS score (p = .01), higher incidence of coronary artery disease (p = .04) and lower left ventricular ejection fraction (p < .001). In TC group, primary endpoint occurred twice less without reaching significance compared to TF group (n = 8; 10.0% vs. n = 10; 19.6% respectively; p = .1). Incidence of MVC was higher in TF group (11.8 vs. 1.3% in the TC group; p = .01) with similar incidence of stroke between groups (p = .8). CONCLUSIONS: Despite higher patient risk profile, TC approach in complex aortofemoral anatomy provides similar favorable outcomes with less MVC compared to TF approach.

INTRODUCTION: The rate of unknown glaucoma is around 50% in industrialized countries. The purpose of our study was to estimate the prevalence of unknown cases of ocular hypertension, glaucoma suspects, and glaucoma in patients consulting for refractive disorders in France. METHODS: A retrospective study in the Point Vision ophthalmology center was led in Toulouse, France. All participants consulting for refractive disorders between June 2015 and June 2017 in the ophthalmology center were included. The cases were identified by the assessment of intraocular pressure, optic nerve head structure, and visual field. Ocular hypertension was defined as an intraocular pressure >21 mm Hg. Glaucoma was defined as the association of a glaucomatous papilla and two successive pathological visual fields. Glaucoma suspect was defined as the association of a glaucomatous papilla without visual field defect. The primary endpoint was the prevalence of unknown ocular hypertension, glaucoma suspects, and glaucoma in patients seen in an ophthalmology center. RESULTS: A total of 66,068 patients (mean age = 37 years) consulted for a refraction visual assessment during the study period. Among them, 234 had a visual field and a retinal nerve fiber layer assessment for ocular hypertension and/or suspicious papilla. The prevalence of unknown cases of ocular hypertension, glaucoma suspect, and glaucoma was 2.6, 0.8, and 0.5 per 1,000 consultants, respectively. Median age at diagnosis of ocular hypertension, glaucoma suspect, and glaucoma was 52, 53, and 65 years, respectively. CONCLUSION: The present study highlights the importance of glaucoma screening in people over 40 years old with the measurement of intraocular pressure and an optic nerve head assessment.

PURPOSE: Glaucoma is the leading cause of irreversible blindness worldwide. The brain and eye share many characteristics, so the eye may provide an easy-access window on brain processes. The aim of the study was to evaluate the link between glaucoma as well as intraocular pressure (IOP)-lowering drops load and all-cause dementia. METHODS: This was a nested case-control study based on the French national healthcare database from 1 January 2006 to 31 December 2018in individuals aged ≥60 years. We compared cases of incident all-cause dementia with 1:5 controls matched by date of case diagnosis (index date), age, sex, and income. We set a 5-year exposure to glaucoma period ending 2 years before the index date (lag-time period to avoid protopathic bias). The main outcome was glaucoma defined with hospitalization related to POAG and/or dispensations of IOP-lowering drops. The secondary outcome was the IOP-lowering drops load. RESULTS: In total, 4810 incident all-cause dementia and 24 050 matched controls were analysed (median [IQR] age 82 [10] years; 66.6% women). The prevalence of glaucoma was 14.0% in controls and cases. Risk of all-cause dementia was not associated with glaucoma (crude OR, 1.02; 95% CI [0.93-1.11]; p = 0.7; adjusted OR, 0.99; 95% CI [0.91-1.09]; p = 0.9) or IOP-lowering drops load (p = 0.2). CONCLUSION: The present study in general population ≥60 years old in France did not find any association between glaucoma and incident all-cause dementia.

PURPOSE: To conduct a review of glaucoma management in France. METHOD: A 15-question survey was sent to ophthalmologists listed in the journal Réalités Ophtalmologiques and the Syndicat National des Ophtalmologues de France. RESULTS: 459/471 responses were analyzed. Gonioscopy was performed by 64.7% of respondents with a Goldmann three-mirror lens, by 51.4% with a four-mirror lens, and 8.2% preferred to perform the procedure with anterior segment imaging. The visual field was reported to be interpreted without difficulty by 87.8% of the practitioners, and 54.0% utilize a progression software. Ultrasound biomicroscopy was reported to be interpreted without difficulty by 20.0% of practitioners. In cases of severe ocular hypertonia with flat bleb in early postoperative trabeculectomy, 61.7% chose ocular massage as a first-line treatment, 52.9% chose laser suture lysis, 50.5% utilized needling, and 24.8% employed hypotonizing eyedrops. In case of severe ocular hypertonia with flat bleb in early postoperative deep sclerectomy, 53.2% chose goniopuncture as their first treatment, 34.4% employed needling, 31.8% utilized ocular massage, and 23.3% chose hypotonizing eyedrops. The selective laser trabeculoplasty is used as soon as the diagnosis is made by 37.5%, in association with a mono or dual therapy by 93.2%, after trying different combinations of eyedrops by 45.5%, when the visual field deteriorates despite a normalized intraocular pressure by 46.6%, and in cases of hypertonia after filtering surgery by 19.2%. Concerning management for primary angle-closure glaucoma, 80.8% considered peripheral iridotomy, and 18.7% utilized cataract surgery. CONCLUSION: The diversity of responses concerning glaucoma management should draw attention to the need for standardized practices.

INTRODUCTION: Anti-vascular endothelial growth factor (VEGF) therapy is the first-line treatment for diabetic macular edema (DME). We investigated the effect of initial glycosylated hemoglobin (HbA1c) level and glomerular filtration rate (GFR) on treatment outcomes in patients with DME receiving anti-VEGF injections in routine clinical practice. METHODS: A retrospective analysis of data from the prospective, multi-center, observational Fight Retinal Blindness! registry was performed. A total of 178 eyes with DME treated with anti-VEGF agents (ranibizumab or aflibercept) from 1 January 2010 to 31 March 2019 were enrolled in the analysis, with the long study period to allow for up to 24 months of follow-up. Data for eyes were tracked in the Fight Retinal Blindness! registry, and clinical parameters were collected by using local software. Changes in visual (best-corrected visual acuity [BCVA], in letters) and anatomic outcomes (central subfield thickness [CST], in microns) between subgroups of patients according to baseline HbA1c level (≤ 7% vs. > 7%) and GFR (> vs. ≤ 60 ml/min/m2 at 24 months were assessed. RESULTS: The multivariate adjusted mean improvement in BCVA at 24 months of treatment was + 5.2 and + 6.8 letters in subgroups with baseline HbA1c level ≤ 7% and > 7%, respectively (p = 0.541), and + 6.9 and + 6.4 letters in subgroups with GFR > 60 and < 60 ml/min/1.73 m2, respectively (p = 0.852). The multivariate adjusted mean CST reduction was - 89.9 and - 76.4 µm in subgroups with baseline HbA1c level ≤ 7% and > 7%, respectively (p = 0.505), and - 85 and - 115 µm in subgroups with baseline GFR > 60 and ≤ 60 ml/min/1.73 m2, respectively (p = 0.130). CONCLUSION: These results seem to indicate that visual and anatomical improvement in patients receiving intravitreal VEGF inhibitors for DME are independent of baseline HbA1c level and GFR, leading to the conclusion that high HbA1c levels or low GFR should not dictate injection timing in routine clinical practice. This study offers valuable insights for ophthalmologists, enabling a personalized treatment approach and optimizing DME patient outcomes.
Our study investigated how initial levels of glycosylated hemoglobin (HbA1c) and glomerular filtration rate (GFR) influence the treatment outcomes of diabetic macular edema (DME). DME is a complication of diabetes characterized by retinal swelling and vision problems. We analyzed data from a registry of DME patients who received intravitreal injections of medication to reduce swelling. Our study included 178 eyes receiving anti-vascular endothelial growth factor (anti-VEGF) injections in routine clinical practice. The results indicated that the initial HbA1c levels and GFR at baseline did not demonstrate a significant influence on the visual and anatomical improvements observed in patients with DME after 24 months of treatment, suggesting that HbA1c levels and kidney function should not be the primary factors taken into consideration in determining the timing of injections in routine clinical practice. These findings emphasize the importance of a personalized treatment approach that considers individual patient factors beyond HbA1c levels and kidney function to optimize outcomes for DME patients. This information can guide ophthalmologists in making informed decisions on the timing and frequency of injections for their patients with DME.
RESUMO
PURPOSE: Preserflo MicroShunt is a minimally-invasive glaucoma drainage micro-tube used to shunt aqueous humor from the anterior chamber to the subtenon space. The safety of the procedure was considered satisfactory with a majority of minor side effects. OBSERVATION: We describe the 5 year endothelial cell loss after Preserflo implantation in 2 primary open angle glaucoma patients. The case 1 presented a device-cornea touch after a backward migration of the device. The case 2 presented a modified aspect of the device compatible with an inflammatory reaction. Both cases were explanted. CONCLUSION: As described in Ahmed glaucoma valve, Xen gel stent and Cypass, Preserflo MicroShunt can lead to endothelial cell loss in some cases. A long-term prospective study with pre and postoperative endothelial cell count and AS-OCT or UBM evaluation of the device positioning would be of great interest to assess the real impact of Preserflo MicroShunt and risk factors for endothelial cell loss.
RESUMO
PURPOSE: Cataract and glaucoma are among the leading causes of blindness worldwide in older people, and they are often concomitant. To assess topical intraocular (IOP)-lowering agents delivery changes after cataract extraction. MATERIAL AND METHODS: Longitudinal matched exposed-unexposed study from the French national healthcare database from January 1, 2005 to January 1, 2017. We compared individuals using topical IOP-lowering agents who underwent bilateral cataract extraction with individuals matched on IOP-lowering agents load, age, and sex who did not undergo cataract extraction. IOP-lowering agents number of drops was assessed 12 months before the first cataract extraction and compared with number of drops 12 months after the second cataract extraction. RESULTS: About 1194 individuals treated with IOP-lowering agents were included, 597 exposed to bilateral cataract extraction and 597 unexposed to any surgery (total mean age 74.8 ± 8.3 years; 69.0% women). Mean IOP-lowering agents delivery at baseline was 1.4 daily drops in both groups. The mean number of drops decreased greater in the exposed than unexposed group (-25.5% vs -3.5%; p < 0.0001). Overall, 159 (26.6%) and 48 (8.0%) individuals in the exposed and unexposed groups interrupted medication (p < 0.0001). CONCLUSIONS: A decrease of around one quarter of IOP-lowering agents delivery was observed after cataract extraction in the present real-life study with a longstanding interruption observed in one quarter of patients. Phacoemulsification as a standalone procedure reduces IOP-lowering agents delivery in ocular hypertension and glaucoma.

(1) Background: To compare macular pigment optical density (MPOD) and its spatial distribution between eyes with primary open-angle glaucoma (POAG) and control eyes in an elderly population. (2) Methods: The Montrachet study (Maculopathy Optic Nerve and nutrition neurovAsCular and HEarT) is a population-based study including participants aged 75 years and over. All participants had a slit lamp examination, fundus photographs, and a questionnaire about their medical past history and smoking status. Optic disc spectral domain optical coherence tomography was also performed. All glaucoma-suspected patients were convocated to have a new full examination. We only retained one eye with POAG for analysis in the glaucoma group and one eye without optic neuropathy in the control participants group. MPOD measurements were performed with the two-wavelength autofluorescence method (488 and 514 nm). (3) Results: Overall, 601 eyes had MPOD measurements among 1153 participants. Among the 601 eyes, 48 had POAG. The mean age for the glaucoma and control participants was 84.01 ± 4.22 years and 81.94 ± 3.61 years, respectively (p < 0.001). In the multivariable analysis, we could not find any association between POAG and MPOD at 0.5° (p = 0.336). We found no significant difference regarding MP spatial distribution between the two groups (p = 0.408). (4) Conclusion: In this elderly population-based study, eyes with POAG and control eyes without optic neuropathy did not differ in terms of MPOD and MP spatial distribution.
RESUMO
Purpose: Visual impairment is a major cause of disability and impairment of cognitive function in older people. Brain structural changes associated with visual function impairment are not well understood. The objective of this study was to assess the association between visual function and cortical thickness in older adults. Methods: Participants were selected from the French population-based ESPRIT cohort of 2259 community-dwelling adults ≥65 years old enrolled between 1999 and 2001. We considered visual function and brain MRI images at the 12-year follow-up in participants who were right-handed and free of dementia and/or stroke, randomly selected from the whole cohort. High-resolution structural T1-weighted brain scans acquired with a 3-Tesla scanner. Regional reconstruction and segmentation involved using the FreeSurfer image-analysis suite. Results: A total of 215 participants were included (mean [SD] age 81.8 [3.7] years; 53.0% women): 30 (14.0%) had central vision loss and 185 (86.0%) normal central vision. Vision loss was associated with thinner cortical thickness in the right insula (within the lateral sulcus of the brain) as compared with the control group (mean thickness 2.38 [0.04] vs 2.50 [0.03] mm, 4.8% thinning, pcorrected= 0.04) after adjustment for age, sex, lifetime depression and cardiovascular disease. Conclusion: The present study describes a significant thinning of the right insular cortex in older adults with vision loss. The insula subserves a wide variety of functions in humans ranging from sensory and affective processing to high-level cognitive processing. Reduced insula thickness associated with vision loss may increase cognitive burden in the ageing brain.
RESUMO
Purpose: To evaluate risk factors associated with keratoconus in a monocentric cross-sectional case-control study. Methods: This observational study occurred from June 2019 to February 2021 in a university hospital (France). The case group consisted of 195 patients with keratoconus in at least one eye who were followed up by a corneal specialist. The control group consisted of 195 patients without any evidence of keratoconus on slit-lamp examination and corneal topography, who were matched 1 : 1 to controls by age and sex. Data were collected by a self-completed paper questionnaire before the consultation, and a multivariate logistic regression was performed. Results: Multivariate analysis revealed significant associations of keratoconus with family history (odds ratio [OR] = 22.2, p < 0.001), rubbing eyes (OR = 10.9, p < 0.001), allergy (any kind) (OR = 3.80, p < 0.001), smoking exposure (OR = 2.08, p=0.017), and dry eyes (OR = 1.77, p=0.045f). The worst eye was associated with the more rubbed eye (p < 0.001) and the more pressed eye during the night according to sleeping position (p < 0.041). Conclusion: This study confirmed the association between keratoconus and eye rubbing, family history, and allergy. It highlighted the role of pressure on the eyes during sleep. Other less known risk factors such as dry eyes and smoking exposure should be explored in future studies.
RESUMO
PRECIS: Micropulse transscleral cyclophotocoagulation (MP-TSCPC) with a 120-second setting reduces intraocular pressure (IOP) with a 6-month success of 45.5%. Only late (>6 mo) failure seem to present a benefit for retreatment. PURPOSE: The purpose of this study was to assess MP-TSCPC efficacy, safety, factors of success, and retreatment benefit in open-angle glaucoma. PATIENTS AND METHODS: A retrospective consecutive case series study. We included patients with open-angle glaucoma who were naive of a cycloablative procedure and underwent MP-TSCPC at 2000 mW for 120 seconds between May 1, 2017, and October 31, 2019. Success was defined as IOP >5 and ≤21 mm Hg with IOP reduction ≥20% from baseline, without any retreatment and visual acuity better than negative light perception. MP-TSCPC retreatment was early and late, before and after 6 months postoperatively, respectively. RESULTS: We included 94 eyes in 94 patients [mean (SD) age: 67.2 (13.4) y; 47.9% women]. The mean preoperative IOP was 24.9 (7.1) mm Hg and was reduced to 18.9 (6.3) at month 6 (P<0.0001). The success rate decreased progressively over time and reached 45.5% at 6 months. Patients with 6-month surgical success had lower mean axial length than others [24.1 (1.5) vs. 25.5 (2.1) mm, P=0.05]. In patients with early and late MP-TSCPC retreatment, the 6-month success rate was 16.7% and 63.6%, respectively. CONCLUSIONS: MP-TSCPC performed with a 120-second setting reduced IOP, with 45.5% success at month 6 and few complications. Axial length was newly described as affecting success, probably linked to the ciliary-body position. Retreatment seemed to be of little benefit in nonresponders or those with early failure. Further studies on laser settings and ciliary-body location are required to find the best risk-benefit protocol.

BACKGROUND: To estimate the 10-year incidence of referable diabetic retinopathy (DR) in a French population with type 1 and 2 diabetes mellitus (DM). A secondary objective was the assessment of safe screening intervals in patients with diabetes without retinopathy. METHODS: Observational, prospective and multicentric study between June 2004 and September 2017 based on a regional screening programme for DR in the Paris region. The incidence of referable DR in patients without retinopathy at baseline was calculated by the Turnbull survival estimator. A safe screening interval was defined as a 95% probability of remaining without referable DR. RESULTS: Among the 25 745 participants with type 1 (n=6086) or type 2 (n=19 659) DM, the 10-year cumulative incidence of referable DR was 19.10% (95% CI 17.21% to 21.14%) and 17.03% (15.78% to 18.35%), median (IQR) follow-up=3.33 (4.24) years. The safe screening interval for patients without DR at the first examination for type 1 and 2 DM was 2.2 (95% CI 2.0 to 2.4) and 3.0 (2.9 to 3.1) years, respectively. In a subgroup of low-risk patients with type 2 DM, the safe screening interval was 4.2 (3.8 to 4.6) years. CONCLUSIONS: These data suggest that in Paris area, a 2-year, 3-year and 4-year screening interval was considered safe for type 1 DM, type 2 DM and for low-risk patients with type 2 DM, respectively, without DR at the first examination. While these data might be used to support the consideration of extending screening intervals, a randomised clinical trial would be suitable to confirm the safety for patients with DM.

BACKGROUND: To assess the efficacy and safety of the second-generation probe of ultrasonic circular cyclocoagulation (UC3) in naive or refractory glaucoma, with a 6-month follow-up. METHODS: A retrospective consecutive case-series study included patients having a UC3 procedure with the second-generation probe of the EyeOP1 device, intraocular pressure (IOP) ≥ 21 mmHg and under maximum tolerated medical treatment, with or without previous glaucoma surgery. Surgical success was defined at the 6-month post-operative visit as IOP > 5 and ≤ 21 mmHg with IOP reduction ≥ 20% from baseline, without any reoperation, and visual acuity better than negative light perception. RESULTS: 100 patients were included and 97 (97.0%; 97 eyes) attended the 6-month follow-up. At 6 months, surgical success was obtained in 48 eyes (49.5%). Intraocular pressure was reduced from a mean ± SD preoperative value of 28.0 ± 5.6 mmHg to 19.3 ± 7.1 mmHg at 6 months (p<0.0001). The proportion of eyes requiring oral acetazolamide decreased from 57.0% to 30.0% between baseline and 6 months after surgery (p = 0.0007). We observed 15 (15.0%) cases of postsurgical macular edema, 8 (8.0%) of hypotony, and 20 (20.0%) of visual acuity loss > 2 Snellen lines. Postsurgical macular edema was associated with a history of epiretinal membranes, uveitis or retinal detachment. Risk factors for hypotony were a history of diabetes or trabeculectomy. CONCLUSIONS: The second-generation UC3 probe significantly reduced IOP in eyes with naive and refractory glaucoma but severe post-operative complications were often observed. Further studies are needed to better identify responders and decrease the high risk for complications associated with the procedure.

PURPOSE: Preservatives contained in glaucoma eye drops have been shown to have a deleterious impact on the ocular surface. We aimed to assess the association between preservative exposure and the occurrence of further glaucoma surgery among patients with glaucoma or ocular hypertension in France. METHODS: The study concerned all patients who first received glaucoma eye drop treatments in a French medical-administrative database (EGB) between 2008 and 2015. Three groups were created according to the level of preservative exposure during the whole follow-up: '0% preservatives', 'mixed' and '100% preservatives'. The occurrence of glaucoma surgery was estimated according to preservative exposure indicators in Cox multivariate models adjusted on age, sex, number of glaucoma eye drops simultaneously used, systemic antihypertensive treatment and duration of treatment. RESULTS: The sample consisted of 12 454 patients. The median (interquartile range) follow-up was 4.1 (1.7-6.1) years. A total of 231 (1.9%) patients underwent glaucoma surgery during follow-up. On multivariable analysis, the risk of glaucoma surgery was increased for the 'mixed' group (hazard ratio [HR] = 3.94 [95% CI, 1.54-10.05]) and for the '100% preservative' group (HR = 7.97 [95% CI, 3.07-20.67]) when compared with the 0% preservative group. CONCLUSION: We found an association between exposure to glaucoma eye drop preservatives and the prevalence of further glaucoma surgery. While these data might be used to support the consideration of routine use of preservative-free drops, in the absence of a randomized clinical trial, they cannot prove a direct cause-and-effect relationship between preservative-free glaucoma eye drops and further glaucoma surgery.
