Abstract
BACKGROUND Incomplete vascularization of the retina in preterm infants carries a risk of retinopathy of prematurity (ROP). Progress in neonatal resuscitation in developing countries has led to the survival of an increasing number of premature infants, resulting in an increased rate of ROP and consequently in visual disability. Strategies to reduce ROP involve optimizing oxygen saturation, nutrition, and normalizing factors such as insulin-like growth factor 1 and n-3 long-chain polyunsaturated fatty acids (LC-PUFA). Our previous study, OmegaROP, showed that there is an accumulation or retention of docosahexaenoic acid (DHA) in mothers of infants developing ROP, suggesting abnormalities in the LC-PUFA placental transfer via fatty acid transporting proteins. The present study aims to better understand the LC-PUFA transport dysfunction in the fetoplacental unit during pregnancy and to find a novel target for the prevention of ROP development. METHODS The study protocol is designed to evaluate the correlation between the expression level of placental fatty acid receptors and ROP occurrence. This ongoing study will include 100 mother-infant dyads: mother-infant dyads born before 29 weeks of gestational age (GA) and mother-infant dyads with full-term pregnancies. Recruitment is planned over a period of 46 months. Maternal and cord blood samples as well as placental tissue samples will be taken following delivery. ROP screening will be performed using wide-field camera imaging according to the International Classification of ROP consensus statement. DISCUSSION The results of this study will have a tangible impact on public health. Indeed, if we show a correlation between the expression level of placental omega-3 receptors and the occurrence of ROP, it would be an essential step in discovering novel pathophysiological mechanisms involved in this retinopathy. TRIAL REGISTRATION NCT04819893.

Abstract
(1) Background: The aim was to describe the rate and outcomes of cystoid macular edema (CME) after pars plana vitrectomy (PPV) for primary rhegmatogenous retinal detachment (RRD) and to identify risk factors and imaging characteristics. (2) Methods: A retrospective consecutive case study was conducted over a 5-year period among adult patients who underwent PPV for primary RRD repair. The main outcome measure was the rate of CME at 12 months following PPV. (3) Results: Overall, 493 eyes were included. The CME rate was 28% (93 patients) at 12 months. In multivariate analysis, eyes with worse presenting visual acuity (VA) (odds ratio [OR], 1.55; 95% CI, 1.07–2.25; p = 0.02) and grade C proliferative vitreoretinopathy (PVR) (OR, 2.88; 95% CI, 1.04–8.16; p = 0.04) were more at risk of developing CME 1 year after PPV. Endolaser retinopexy was associated with a greater risk of CME than cryotherapy retinopexy (OR, 3.06; 95% CI, 1.33–7.84; p = 0.01). Eyes undergoing cataract surgery within 6 months of the initial RRD repair were more likely to develop CME at 12 months (OR, 1.96; 95% CI, 1.06–3.63; p = 0.03). (4) Conclusions: CME is a common complication after PPV for primary RRD repair. Eyes with worse presenting VA, severe PVR at initial presentation, endolaser retinopexy, and cataract surgery within 6 months of initial RRD repair were risk factors for postoperative CME at 12 months.

Abstract
Purpose To report a case of bilateral acute macular neuroretinopathy following the first dose of Oxford-AstraZeneca COVID-19 (coronavirus disease 2019) vaccine in a young, Caucasian, and healthy woman. Observations A 25-year-old Caucasian female patient presented to the ophthalmology department of Dijon University Hospital with a 3-week history of black spots and paracentral scotoma in both eyes. She had no past medical history and was using the combined estrogen-progestin oral contraceptive (COC). These symptoms occurred 24 h after receiving the first Oxford-AstraZeneca COVID-19 vaccination dose. The ophthalmologic signs were preceded a few hours earlier by fever and flu-like symptoms. Ophthalmologic examination revealed a preserved visual acuity with a quiet anterior segment and normal fundus in both eyes. Findings on multimodal retinal imaging, particularly near-infrared reflectance (NIR) and optical coherence tomography (OCT) imaging, were classical of an acute macular neuroretinopathy in both eyes. Conclusions and importance COVID-19 vaccination is justified as an essential public health measure. Acute macular neuroretinopathy may occur in patient receiving a COVID-19 vaccination dose. Further reports are needed to confirm this association. Physicians should be aware of this complication and request an eye examination with at least OCT or NIR imaging in the case of any visual symptoms after vaccination, notably in young women using COC.

Abstract
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.

Abstract
PURPOSE To evaluate the efficacy of intravitreal anti-vascular endothelial growth factor (anti-VEGF) injections (IVT) in diabetic macular edema (DME) in real-life practice using the Save Sight Registries (SSR). MATERIAL AND METHODS We conducted an observational, single-centre, retrospective study in the department of ophthalmology of the Dijon University Hospital. We included treatment-naive patients who presented with DME between January 2016 and December 2017. Demographic and clinical data, follow-up visits, and treatments administered were entered into the SSR, an international online ophthalmic registry. Primary endpoints were the change in best-corrected visual acuity (BCVA) and central subfield thickness (CST) from baseline to 12 and 24 months. RESULTS Fifty-eight eyes of 43 patients with a mean [standard deviation (SD)] age of 67.1 [9.5] years were included. Forty-one eyes completed 12 months of follow-up, and 17 eyes completed 24 months of follow up. Median [SD] baseline BCVA was 56.1 [22.9] ETDRS letters and the median [95% confidence interval (95% CI)] baseline CST was 447.9 [161.0] micrometers (μm). Median [95% CI] improvement in BCVA from baseline to months 12 and 24 were respectively, +5.6 [+0.5; +10.7] ETDRS letters and +7.7 [-2.8; +18.2] ETDRS letters. The median [95% CI] decrease in CST from baseline to months 12 and 24 were respectively, -110.9 [-154.5; -67.3] μm and -125.5 [-198.0; -53.0] μm. CONCLUSION Our clinical practice can be evaluated easily with the SSR system. In real life, anti-VEGF IVT are an effective treatment for DME, which result in improved BCVA and decreased CST.

Abstract
INTRODUCTION Quantitative measurements of retinal microvasculature by optical coherence tomography angiography (OCT-A) have been used to assess cardiovascular risk profile. However, to date, there are no studies focusing on OCT-A imaging in the setting of the altered hemodynamic status found in high-risk cardiovascular patients. METHODS To determine the potential association between retinal vascular density on OCT-A and a comprehensive battery of hemodynamic variables in patients with myocardial infarction (MI) using data from the acute phase and at 3 months follow-up after cardiac rehabilitation. This prospective longitudinal study included patients who presented with MI in the cardiology intensive care unit at Dijon University Hospital. Main outcomes and measurements were retinal vessel density on OCT-A, hemodynamic status based on left ventricular ejection fraction (LVEF), and indexed cardiac output during the acute phase of myocardial infarction and at 3 months follow-up. RESULTS Overall, 30 patients were included in this pilot study. The median (IQR) age was 64 years (55-71) with 87% men. At admission, the mean (SD) LVEF was 53% (11), and the mean indexed cardiac output was 2.70 (0.83) L/min/m2. On OCT-A, the mean inner retinal vascular density was 19.09 (2.80) mm-1. No significant association was found between retinal vascular density and hemodynamic variables. CONCLUSION We found no significant association between retinal vascular density on OCT-A and hemodynamic variables in the acute phase of a myocardial infarction or after 3 months of cardiac rehabilitation. Therefore, OCT-A findings do not seem to be influenced by the hemodynamic changes associated with myocardial infarction.

Abstract
Purpose The aim of this study was to investigate the prevalence of subretinal drusenoid deposits (SDD) and to identify associated factors in an elderly population. Methods The participants of the population-based Montrachet study underwent an exhaustive ophthalmologic examination, including color fundus photography and macular spectral domain-optical coherence tomography (SD-OCT), coupled with infrared reflectance imaging. The presence of SDD and other age-related macular degeneration lesions, according to the European Eye Epidemiology SD-OCT classification of macular diseases, and subfoveal choroidal thickness were recorded. Moreover, the association of SDD and both clinical and demographic factors as well as plasma levels of vitamin E and lutein/zeaxanthin (L/Z) were analyzed. Results The mean age of patients was 82.3 ± 3.8 years and 62.7% were female. The prevalence of SDD was 18.1% (n = 205) in the subjects with at least one eye interpretable (n = 1135). In multivariate analysis, SDD was positively associated with increasing age (OR, 4.6; 95% CI, 2.8-7.7; P < 0.001 for subjects aged >85 years), female sex (OR, 1.7; 95% CI, 1.2-2.4; P = 0.005), and plasma L/Z level (OR, 1.2; 95% CI, 1.0-1.5; P = 0.039), and negatively associated with lipid-lowering drugs use (OR, 0.5; 95% CI, 0.3-0.9; P = 0.014 for statin medications) and subfoveal choroidal thickness (OR, 0.8; 95% CI, 0.7-0.9; P = 0.002). Conclusions The prevalence of SDD was high in subjects older than 75 years, more frequent in women, and was associated with a thinner choroid. The association with lipid-lowering drugs deserves further investigation.

Abstract
Iodinated contrast agent (ICA)-induced acute kidney injury (AKI) following acute coronary syndrome (ACS) is a frequent complication, which may lead to chronic kidney disease and increased mortality. Optical coherence tomography angiography (OCT-A) of the retina is new tool delivering a rapid and noninvasive assessment of systemic microvascularization, which is potentially involved in the occurrence of ICA-induced AKI. Between October 2016 and March 2017, 452 ACS patients were admitted to our cardiac intensive care unit. OCT-A was performed within 48 h after the ICA injection. Patients with a history of retinal disease were excluded. The patients included were divided into two groups depending on whether or not AKI occurred after injection of ICA, according to KDIGO criteria. Of the 216 patients included, 21 (10%) presented AKI. AKI was significantly associated with age, Mehran score, GRACE score, and NT-proBNP. AKI patients had significantly lower retinal vascular density (RVD)) and had more frequent low RVD (81% vs 45%, P = 0.002). Adding low RVD to the Mehran score and the NT-proBNP, or to the GRACE score and the NT-proBNP, significantly improved their predictive values, suggesting that systemic microvascular involvement remains incompletely addressed by either standard risk scores or factors known to be associated with ICA-induced AKI.

Abstract
Purpose To compare the efficacy and safety of a newly developed ophthalmic solution containing carteolol 2% and pilocarpine (2% (CBS341A) with a timolol 0.5% and pilocarpine 2% fixed combination. Patients and Methods. A randomized, double-masked, multicenter study was conducted in 209 patients with primary open-angle glaucoma or ocular hypertension, whose intraocular pressure (IOP) was higher than 21 mm Hg on bet-blocker twice a day alone. The test medications were administered twice daily for 4 months. IOP was measured at 9 and 11 a.m. at the beginning of the study (with beta-blocker alone) and after one and four months of treatment. Adverse effects were recorded. Results Both combinations caused a similar, statistically significant decrease in IOP. At four months, in the CBS341A group a 2.4 mm Hg (9%) reduction in IOP was achieved at 9 a.m. and 4.1 mm Hg (17.3%) at 11 a.m. compared with respectively 3 mm Hg (11%) and 4.5 mm Hg (19.5%) in the timolol-pilocarpine group. No statistical difference was observed between the two groups in safety and efficacy. Conclusions The carteolol-pilocarpine combination appears as safe and as effective as the timolol-pilocarpine combination in the medical treatment of primary open-angle glaucoma or ocular hypertension.

Abstract
INTRODUCTION Cat scratch disease is a pleiomorphic condition, sometimes with isolated ophthalmic involvement. We report the clinical observations of seven cases with ophthalmologic manifestations of cat scratch disease. OBSERVATIONS There were seven patients, with a median age of 52 years, of whom five were women and three had unilateral involvement. Six exhibited Leber's stellate neuroretinitis, an incomplete syndrome in two cases, and one associated with chorioretinal foci. One patient had isolated retinal infiltrates. The diagnosis of cat scratch disease was confirmed by Bartonella henselae serology, positive in all cases. All patients received treatment with doxycycline. Ocular complications (with optic atrophy and macular retinal pigment epithelial changes) were noted in five cases. DISCUSSION Ocular bartonellosis is an atypical clinical form. It requires a directed ancillary work-up with serology or PCR, which has the peculiarity of being highly specific if not very sensitive. Treatment is above all preventive. Antibiotics may be initiated. CONCLUSION Cat scratch disease must be excluded in the work-up of posterior uveitis.

Abstract
PURPOSE To report preoperative prognostic factors associated with visual acuity recovery 1 year after combined cataract and idiopathic epiretinal membrane (ERM) surgery and to introduce a predictive score. DESIGN Interventional case series and estimation of a predictive score. METHODS One hundred forty-two patients (1 eye per patient) operated on for combined cataract and idiopathic ERM in the University Hospital of Dijon were followed for 12 months. Preoperative clinical features and spectral-domain optical coherence tomography (OCT) parameters were compared between eyes that recovered ≥20/20 final best-corrected visual acuity (BCVA) and those with <20/20 final BCVA. Multivariate analysis and predictive score were provided. RESULTS At 12 months, 60 eyes (42%) recovered ≥20/20 BCVA and 82 (58%) had lower visual results. Logistic regression analysis showed that final BCVA was associated with age (P = .040), duration of symptoms (P = .025), initial BCVA (P = .002), and inner and outer segment (IS/OS) junction disruption on spectral-domain OCT (P = .010). The preoperative 10-point predictive score including these parameters reached 82% sensitivity and 66% specificity. With a score >5, patients had a ≥56% chance of recovering 20/20 final BCVA instead of ≤27% when the score was ≤5. CONCLUSIONS Age, duration of symptoms, and initial BCVA appear to be reliable prognostic factors in patients undergoing combined cataract and idiopathic ERM surgery. Combining these factors with analysis of the IS/OS junction provides a predictive score to estimate individual chances of good visual outcome.

Abstract
PURPOSE To assess and compare frequencies and incidence rates of subretinal hemorrhage (SRH) after intravitreal anti-VEGF injections and spontaneous SRH in patients with exudative age-related macular degeneration (AMD). PATIENTS AND METHODS This retrospective monocentric study included 1079 patients followed for exudative AMD in the ophthalmology department of the university hospital of Dijon from January 2007 to July 2012. For each SRH occuring during this period, the number of previous treatments with intravitreal anti-VEGF was determined, as well as the time between the last injection and the hemorrhage. The SRH was considered as an adverse effect of the anti-VEGF injection if it occurred within 2 months after the last IVT (post-IVT SRH). Frequencies and incidence rates of post-IVT SRH and spontaneous SRH were calculated. RESULTS Sixty-six SRH's occurred during the study period with a total frequency of 6.12% (CI95% [4.69-7.55]). Frequencies of spontaneous and post-IVT SRH were respectively 5.65% (CI95% [4.28-7.03]) and 0.46% (CI95% [0.06-0.87]), representing a 12.2 ratio. Post-IVT SRH incidence was 8.3/1000 patient-years (CI95% [1.0-15.5]) and the spontaneous SRH incidence rate was 11.6/1000 patient-years (CI95% [8.3-14.8]), (P=0.472). The incidence rate ratio was 0.72 (CI95% [0.29-1.78]). CONCLUSION This study did not show a statistically significant change in the incidence of SRH after intravitreal anti-VEGF therapy. The benefit/risk ratio of intravitreal anti-VEGF injections for exudative AMD remains high.

Abstract
AIMS The link between diabetic retinopathy (DR) and adipokines is controversial. Some studies suggest that visceral fat and adipokines could be additional risk factors for DR. The aim of this study was to determine the relationship between abdominal fat or adipokine secretion and DR in patients with type 2 diabetes mellitus (DM). METHODS A total of 179 patients with type 2 DM were included. Each patient underwent measurement of plasma adiponectin and leptin and an evaluation of body fat distribution (visceral and subcutaneous) with MRI. The severity of DR was evaluated according to the classification of the American Academy of Ophthalmology. Patients were classified in 3 groups: absence of DR, mild and moderate DR, and advanced DR (severe, proliferative and laser-treated DR). RESULTS There were no significant differences between the 3 groups for adiponectin, leptin and visceral or subcutaneous fat accumulation. Patients with DR had a mean duration of diabetes, serum creatinine concentration and percentage of macroalbuminuria significantly higher than patients without DR (p < 0.001, p = 0.003 and p < 0.001, respectively). Serum adiponectin increased with the diabetic nephropathy stage (p = 0.007). CONCLUSIONS Our study suggests that body fat distribution and adipokine secretion are not associated with DR in patients with type 2 DM.

Abstract
We report the case of a 68-year-old woman with a chronic unilateral red eye for 3 months. The ophthalmologic exam showed engorged episcleral vessels, proptosis and chemosis. Motility, visual acuity and fundus examination were normal. Neurological examination was also unremarkable. Given the subacute nature of the proptosis in association with engorged episcleral vessels, brain MRI and MRA were performed, demonstrating a right dural-cavernous sinus fistula. After two attempts via the femoral and facial veins, the dural fistula was accessed and treated via the right superior ophthalmic vein. The fistula was occluded and the symptoms regressed in 48 hours. Arteriography at 3 months confirmed a complete cure.

Abstract
INTRODUCTION The aim of this study was to evaluate the yield of glaucoma and ocular hypertension (OHT) screening in association with diabetic retinopathy (DR) screening in a rural population. PATIENTS AND METHODS 676 patients were screened between 2004 and 2005. The four departments the Burgundy region were visited, divided into 39 areas with sparse medical services. Each patient had fundus photographs taken with a nonmydriatic camera and IOP measurement in each eye with a noncontact tonometer. Optic discs were classified into suspect or normal. RESULTS On the 676 screened patients, 41 presented an anomaly (6.1%): 31 with OHT (4.6%), 7 with a suspect optic disc (1.0%), and 3 with both anomalies (0.4%). After further control, we finally found 4 cases of OHT (0.6%) and 8 cases of glaucoma (1.2%). This screening program allowed the diagnosis of 2 new cases of OHT (0.3%) and 4 new cases of glaucoma (0.6%). DISCUSSION This screening improved the quality of the ophthalmic follow-up in rural areas for diabetics. Furthermore, it is a simple and not more expensive way to screen for OHT and glaucoma in these populations. CONCLUSION The itinerant screening of OHT and glaucoma combined with a diabetic retinopathy screening is effective. The screening campaign was renewed for 2 years in semi-rural zones.

Abstract
AIMS To evaluate the differences in meibomian fatty acid composition in healthy subjects and in patients suffering from meibomian gland dysfunction or aqueous-deficient dry eye. METHODS We collected meibomian oil using a sterile Schirmer paper in healthy individuals (n = 20), dry eye patients (aqueous-deficient) (n = 32) and meibomian gland dysfunction (MGD) patients (n = 25) after gentle massage of the lid margin. Meibomian fatty acids were directly transmethylated and analysed using gas chromatography (GC) and GC mass spectrometry. RESULTS Meibomian fatty acids were similar in healthy individuals and in dry eye patients but were different in MGD patients, who showed significantly higher levels of branched-chain fatty acids (29.8% vs 20.2%) (p<0.0001) and lower levels of saturated fatty acids (9.3 vs 24.6%) (p<0.0001), in particular lower levels of palmitic (C16) and stearic (C18) acids. CONCLUSION The increase in branched-chain fatty acids may reflect greater quantities of wax and cholesterol esters and triglycerides in meibomian gland excreta. Since wax and cholesterol esters are the main lipids of meibum, these differences may have physical consequences for tear-film lipid-layer fluidity and stability. Meibomian fatty acid composition and particularly the increase in branched chains could be a marker for meibomian gland dysfunction.

Abstract
BACKGROUND AND PURPOSE Retinal complications may be encountered during the development of hypertension as a response to oxidative stress. Statins may reduce the risk of developing hypertension and ocular diseases. We evaluate the effects of rosuvastatin (ROSU) on retinal functionality and oxidative stress levels in normotensive and spontaneously hypertensive rats (SHR). EXPERIMENTAL APPROACH Wistar Kyoto (WKY) and SHR were treated for 3 weeks with rosuvastatin (10 mg kg(-1) day(-1)). Electroretinograms (ERG) were recorded before and after rosuvastatin treatment. Reactive oxygen species (ROS) were determined in the retina with dihydroethidium staining and NAD(P)H oxidase activity was evaluated. KEY RESULTS Retinal ganglion cell ROS and retinal NAD(P)H oxidase activity were higher in SHR than in WKY rats, respectively (17.1+/-1.1 vs 10.2+/-1.2 AU, P<0.01; 38095+/-8900 vs 14081+/-5820 RLU mg(-1); P<0.05). The ERG b-wave amplitude in SHR was significantly lower than that in WKY rats. Rosuvastatin reduced SBP in SHR but did not change plasma lipid levels. Rosuvastatin treatment in SHR significantly decreased ROS levels (11.2+/-1.3, P<0.01), NAD(P)H activity in retinal ganglion cells (9889+/-4290; P<0.05), and increased retinal plasmalogen content in SHR, but did not modify the ERG response. CONCLUSIONS AND IMPLICATIONS Rosuvastatin, beyond lowering cholesterol levels, was able to lower ROS in the retina induced by hypertension, but without improving retinal function in SHR. These findings point to a complex relationship between ROS in the pathogenesis of retinal disease and hypertension.

Abstract
AIM To investigate the ocular surface inflammatory response to chronic topical treatments in patients with glaucoma by measuring the cytokine level in tears using multiplex bead analysis. METHODS Tear samples were collected from 21 patients with glaucoma and 12 healthy volunteers. Tears were analysed for the presence of 17 cytokines: interleukin (IL)1beta, IL2, IL4, IL5, IL6, IL7, IL8, IL10, IL12, IL13, IL17, granulocyte-colony stimulating factor, granulocyte-macrophage stimulating factor, interferon (INF)gamma, monocyte chemotactic protein (MCP)1, macrophage inflammatory protein 1beta and tumour necrosis factor (TNF)alpha. The cytokines in each sample of tears were measured using multiplex bead analysis with microspheres as solid support for immunoassays. RESULTS In the tears of treated patients, proinflammatory cytokines (IL1beta, IL6, IL12, TNFalpha) were significantly increased compared with controls. T helper (Th)1 (INFgamma, IL2) and Th2 (IL5, IL10, IL4) type cytokines were also significantly higher (p<0.05); however, the most marked increase was observed with Th1 cytokines. The expression of chemokine IL8 and MCP1 was also increased in the treated group. CONCLUSION This study shows that pro-inflammatory cytokine secretion by conjunctival cells is increased in response to topical treatments for glaucoma. The characterisation of cytokines in tears was previously limited by the small volume attainable, a limitation that has been overcome by multiplex analysis.

Abstract
AIMS To evaluate conjunctival expression of trefoil factor family (TFF)1, MUC5AC and human leucocyte antigen (HLA)-DR in patients with glaucoma treated with topical drugs, and to determine whether these parameters can predict the outcome of glaucoma surgery. METHODS 77 conjunctival impression cytology specimens were collected from 77 patients with glaucoma (66 receiving drops with preservative and 11 treated with preservative-free drops) and 43 controls. TFF1, MUC5AC and HLA-DR expression was analysed using flow cytometry. Trabeculectomy was performed in 56 patients; success was defined as an intraocular pressure (IOP) < or =15 mm Hg without any IOP-lowering drug at 6 months. RESULTS The expression of TFF1, MUC5AC and HLA-DR was significantly higher in patients than in controls (p = 0.01, 0.05 and 0.004, respectively). A higher expression of MUC5AC was found in patients treated with preserved drops than in those receiving unpreserved drops (p = 0.04). A higher MUC5AC expression and a lower HLA-DR expression was observed in successful glaucoma surgeries than in failures. CONCLUSIONS TFF1 and MUC5AC secretions are probably a response to mild ocular surface changes caused by long-term use of topical treatment. Their increased expression could be a predicting factor of further successful glaucoma surgery.

Abstract
BACKGROUND Resource utilisation and direct costs associated with glaucoma progression in Europe are unknown. As population progressively ages, the economic impact of the disease will increase. METHODS From a total of 1655 consecutive cases, the records of 194 patients were selected and stratified by disease severity. Record selection was based on diagnoses of primary open angle glaucoma, glaucoma suspect, ocular hypertension, or normal tension glaucoma; 5 years minimum follow up were required. Glaucoma severity was assessed using a six stage glaucoma staging system based on static threshold visual field parameters. Resource utilisation data were abstracted from the charts and unit costs were applied to estimate direct costs to the payer. Resource utilisation and estimated direct cost of treatment, per person year, were calculated. RESULTS A statistically significant increasing linear trend (p = 0.018) in direct cost as disease severity worsened was demonstrated. The direct cost of treatment increased by an estimated 86 for each incremental step ranging from 455 euro per person year for stage 0 to 969 euro per person year for stage 4 disease. Medication costs ranged from 42% to 56% of total direct cost for all stages of disease. CONCLUSIONS These results demonstrate for the first time in Europe that resource utilisation and direct medical costs of glaucoma management increase with worsening disease severity. Based on these findings, managing glaucoma and effectively delaying disease progression would be expected to significantly reduce the economic burden of this disease. These data are relevant to general practitioners and healthcare administrators who have a direct influence on the distribution of resources.

Abstract
AIMS To assess the characteristics and visual outcome of patients with acute postoperative endophthalmitis hospitalized in a referral center. MATERIALS AND METHODS All patients suspected of having infectious endophthalmitis were included in this study. All patients were treated with the same protocol including at least intravitreal injection of antibiotics and instillation of fortified antibiotics. Symptoms, visual acuity, and slit lamp examination were recorded before treatment, at the end of hospitalization and during clinical follow-up. Treatments and biological results were also reported. For patients developing infectious endophthalmitis after cataract surgery, intraoperative management such as location of the incision, suture or sutureless incision, and material of the intraocular lens were also noted. RESULTS Forty-one patients were included in the study over 32 months (33 patients after cataract surgery). Intraocular inflammation and a decrease in subjective visual acuity were the most frequently reported findings (90% and 94%, respectively). Ocular pain and conjunctiva injection were less frequently reported (47% and 48%, respectively). Symptoms occurred 5 days after the surgery (median); 56% of patients needed a second intravitreal injection of antibiotics. There was a significant increase in visual acuity during and after hospitalization; median final visual acuity was 4.6/10 (0.34 log MAR = 20/43); 30% of patients had less than 20/200, but 44% more than 20/40. In endophthalmitis following cataract surgery, incisions were corneal in all cases and sutured in 62% of cases. Incisions were temporal in 55% of patients. DISCUSSION Our results are similar to those previously published for acute endophthalmitis following ocular surgery. Intravitreal antibiotic injection remains the gold standard on the management of acute postoperative endophthalmitis.

Abstract
AIM To study the MUC5AC and the blood group related antigen expression in ocular cicatricial pemphigoid (OCP) according to the distribution of Lewis and secretor phenotypes in OCP patients compared to normal subjects. METHODS Immunostaining was performed on conjunctival biopsy specimens from 22 consecutive patients suffering from OCP, using monoclonal antibodies (Mabs) directed against the peptidic core MUC5AC mucin (anti-M1/MUC5AC Mabs) and against the saccharide moieties (anti-blood group related antigens). These latter included anti-Le(a), anti-Le(b), anti-sialyl Le(a), and H type 2 Mabs, which immunoreact with Lewis positive and non-secretor (Le(a)), Lewis positive and secretor (Le(b)), Lewis positive (sialyl Le(a)), and secretor (H type 2) phenotypes respectively. Serological tests were also performed to confirm the phenotype of each patient. The immunohistopathological patterns and the distribution of Lewis and secretor phenotypes were compared with the results of a previous study in normal individuals. RESULTS (1) In OCP patients compared to the normal population, anti-M1 immunoreactivity of goblet cells was unchanged, whereas anti-Le(a), anti-Le(b), and anti-sialyl Le(a) immunoreactivities of epithelial and/or goblet cells were markedly decreased. (2) 41% of OCP patients had a non-secretor phenotype, which is statistically significantly more than the estimated incidence of the same phenotype in the French population (20%) (p approximately 0.04). CONCLUSIONS Mucins in OCP patients showed a decreased expression of blood group related antigens whereas the MUC5AC peptidic core detected by anti-M1 Mab remained unchanged. These results also seem to indicate that OCP may be associated with a non-secretor phenotype.

Abstract
PURPOSE To evaluate the effect on intraocular pressure (IOP) of switching from timolol to latanoprost or adding latanoprost to timolol in patients with open angle glaucoma or ocular hypertension where IOP is not adequately controlled with timolol. METHODS This was a 6-week, double-masked, randomised multi-centre study. 53 patients with primary open angle glaucoma, capsular glaucoma, or ocular hypertension with an IOP of at least 21 mmHg on current therapy were recruited. After a run-in period of at least 2 weeks on timolol, 5 mg/ml twice daily, patients were randomised to one of three groups. One group continued on timolol, one switched from timolol to latanoprost, 50 microg/ml once daily, and a third group received latanoprost in addition to timolol. The efficacy was evaluated by comparing IOP at 9 AM at baseline and after 6 weeks of treatment. RESULTS IOP at baseline and after 6 weeks of treatment (mean +/- SEM) were 24.2 +/- 0.9 and 23.8 +/- 1.0 mmHg (n = 16) for patients continuing on timolol, 26.3 +/- 1.2 and 19.6 +/- 1.1 mmHg (n = 17) for patients switching to latanoprost, and 23.2 +/- 1.0 and 17.5 +/- 0.8 mmHg (n = 17) for patients with combined treatment. Adding latanoprost to timolol reduced IOP with 5.9 +/- 0.9 mmHg (p < 0.001) and switching from timolol to latanoprost reduced IOP with 5.0 +/- 0.9 mmHg (p < 0.001), which caused in each group a significant IOP reduction of about 25%. CONCLUSIONS The effect of latanoprost was additive to that of timolol, and a good effect on IOP reduction was also achieved by switching from timolol to latanoprost, suggesting that a switch in many patients is an effective alternative to combination treatment.

Abstract
The heat shock protein 70 (HSP-70) mRNA level was evaluated in Long Evans rat retinas after ischemia and after reperfusion following ischemia. Retinal ischemia was induced by ligation of the optic nerve and vessels. Rats were sacrificed after 90 min of ischemia or 120 min of reperfusion following ischemia. Retinas were dissected. Total mRNA was extracted and inducible HSP-70 (iHSP-70) gene expression was analyzed by quantification of transcripts using an RT-PCR assay. Results were expressed in arbitrary units as a ratio of the optical density of iHSP-70/beta-actin electrophoretic bands. iHSP-70 gene expression was 0.220 +/- 0.027 (n = 5), 0.502 +/- 0.045 (n = 5) and 0.468 +/- 0.032 (n = 5) for the sham-operated, ischemia only and ischemia and reperfusion groups, respectively. There was a statistically significant difference between the control and ischemia groups, and between the control and ischemia and reperfusion groups (p < 0.001), suggesting a rapid HSP-70 mRNA expression of the retina due to an ischemic injury.

Abstract
PURPOSE Mucin-related antigens are abundantly expressed by the cells of the normal human conjunctiva. The pattern of these antigens in pterygium, and especially the role of Galbeta1-3GlcNAc alpha2,3-sialyltransferase (ST3Gal III), sialyltransferase necessary to build the sialyl-Le(a) (Lewis(a)) antigen, were studied. METHODS Immunoperoxidase staining was performed on 28 pterygia using different monoclonal antibodies: anti-M1 (against the peptidic core of gastric mucins encoded by MUC 5AC gene), anti-Le(a)(7LE), anti-sialyl Le(a)(NS 19-9), and anti-Le(b)(2-25LE). A serologic Lewis determination was done in 18 patients. ST3Gal III sialyltransferase expression was also studied in 10 healthy conjunctiva and 10 pterygia by reverse transcriptase-polymerase chain reaction (RT-PCR). Glyceraldehyde-3-phosphate-dehydrogenase was used as an endogenous internal control. RESULTS First, Le(a), sialyl Le(a), and Le(b) immunoreactivities either decreased or were no longer detectable in pterygium goblet cells as opposed to normal conjunctiva. Second, unlike in pterygium, the Lewis immunoreactivity, which is mainly located in the surface epithelial cells in the normal conjunctiva, was occasionally restricted to the epithelial cells of the deep layers. However, M1 mucins did show an identical pattern expression in a normal conjunctiva and pterygium. ST3Gal III expression was significantly lower in pterygium (0.20+/-0.02 AU [arbitrary units]) than in normal conjunctiva (0.95+/-0.12 AU). CONCLUSIONS ST3Gal III gene is less expressed in pterygium than in normal conjunctiva. This observation could explain the decrease of sialyl Le(a) expression observed in pterygium by immunohistology.

Abstract
PURPOSE To evaluate whether ocular hypertensive subjects have a higher central corneal thickness than other individuals. METHODS In this prospective study, 48 subjects with ocular hypertension, 63 patients with open-angle glaucoma, 56 nonglaucomatous patients with diabetes mellitus, and 106 control subjects were evaluated. Corneal thickness was measured by ultrasound pachymetry, and intraocular pressure was determined by Goldmann applanation tonometry. RESULTS Central corneal thickness was significantly higher in the ocular hypertensive subjects, mean +/- S.D., 592+/-39 microm, than in the patients with glaucoma (536+/-34 microm), the nonglaucomatous patients with diabetes mellitus (550+/-31 microm), and the normal subjects (545+/-33 microm), P<0.001. The three latter groups did not vary significantly in central corneal thickness, P>0.05. CONCLUSION In some individuals with increased transcorneal measurements of intraocular pressure, the cornea is thicker than in subjects with normal intraocular pressure readings or patients with glaucoma. It suggests that in ocular hypertensive subjects, corneal pachymetry should be performed to rule out an abnormally thick cornea as a reason for falsely high measurements of intraocular pressure.

Abstract
Catalase activity was evaluated in Long Evans rat retina after ischemia and reperfusion. Ischemia was induced by ligation of the optic nerve and vessels. Rats were sacrificed after 15 and 120 min of reperfusion, respectively. Catalase activity was assessed by Claiborne's method and was expressed as U/mg of protein. In the first group, retinas of each animal were pooled. In the second group, ischemia was induced in the right eye with the left eye serving as control. In the first group, enzyme activity was 7.39 +/- 0.26 (n = 11), 7.67 +/- 0.27 (n = 9) and 9.15 +/- 0.45 (n = 7) for the sham-operated, 15- and 120-min reperfusion groups, respectively. There was a significant difference between the control and 120-min reperfusion groups (p < 0.001). In the second group, there was a significant (p < 0.01) increase in catalase activity in the ischemic eye compared to the non-ischemic eye after 15 (n = 7) and 120 min (n = 9) of reperfusion. These findings may suggest a rapid activation of catalase activity during the ischemia-reperfusion sequence.

Abstract
PURPOSE To determine the variations of vitamin E in rat retinas after transient ischemia and reperfusion. METHODS Male Wistar rats 11 to 12 weeks of age were used in all experiments. Ischemia was induced by ligation of the optic nerve and vessels, then reperfusion was obtained by removing the ligature. Retinas were dissected, and vitamin E was analyzed by a modified high-performance liquid chromatography assay. RESULTS There was an insignificant rise in vitamin E during ischemia and a dramatic decrease after reperfusion. No changes were dependent on the period of ischemia (30, 60, or 90 minutes) or reperfusion (15 or 120 minutes). CONCLUSION Vitamin E decreased only in the reperfused groups, demonstrating a depletion of defenses against free radical production occurring during reperfusion. Vitamin E changes may represent an indirect measure of lipoperoxidation during ischemia-reperfusion and, thus, a potential parameter to evaluate drugs in vitro.

Abstract
The penetration of sparfloxacin into the aqueous humor after oral administration was studied in 28 patients undergoing cataract surgery. Each patient received a single, oral dose of 400 mg of sparfloxacin. In eight other patients scheduled to undergo vitreal surgery, multiple daily oral doses were administered for a total amount of 1,000 mg. The aqueous levels were (mean +/- SEM) 0.127 +/- 0.036 microgram/ml to 0.404 +/- 0.159 microgram/ml from two to 24 hours after ingestion. In the vitreous, the mean drug level was 0.840 microgram/ml (range, 0.480 to 2.060 microgram/ml), from 4.3 to 8.0 hours after the most recent oral dose. Blood samples obtained at the same time as vitreous and aqueous taps were assayed by high-performance liquid chromatography. These data demonstrate that therapeutic levels of sparfloxacin may be achieved in noninflamed, noninfected eyes undergoing cataract or vitreous surgery.

Abstract
The ocular hypotensive activities of the two potent topical carbonic anhydrase inhibitors sezolamide (previously known as MK-417) and dorzolamide (previously known as MK-507 and L-671,152) were compared formulated in Gelrite vehicle, a novel ophthalmic drug delivery system. This was a four-center, double-blind, randomized, placebo-controlled, parallel study in 73 patients with a diagnosis of bilateral primary open-angle glaucoma or ocular hypertension and a morning intraocular pressure (IOP) of greater than 23 mmHg in both eyes following washout of ocular hypotensive medications. Parallel 12-h modified diurnal curves were performed prestudy and on day 6, with a 4-h IOP curve on day 1. On day 6 the peak mean percentage decrease in IOP from baseline occurred 4 h after the dose of dorzolamide (22.1%) and 6 h after the dose of sezolamide (21.3%). There were no significant differences between 2% dorzolamide and 1.8% sezolamide at any time point, although the decrease in IOP for sezolamide tended to be slightly greater than that for dorzolamide. Duration of action of both compounds was, at most, slightly prolonged by the use of Gelrite vehicle when compared with former studies on sezolamide and dorzolamide.

Abstract
Hen's egg lysozyme (HEL) activity was measured in vitro with gentamicin and norfloxacin by a turbidimetric technique. Gentamicin at the concentration of 10(-3) M inhibited HEL activity by 39%, while 10(-3) M norfloxacin did not affect HEL activity. However, an in vivo study in healthy persons did not show any significant statistical difference in tear lysozyme activity when 0.3% gentamicin or 0.3% norfloxacin were topically applied.

Abstract
The kinetics of topically applied norfloxacin 0.3 percent were studied in rabbit and man. All measurements were performed by high-pressure liquid chromatography. Norfloxacin concentrations were investigated five to 120 minutes in rabbit ocular tissues after instillation of a single drop. In normal eyes, after 30 minutes, mean +/- SEM levels were 14.3 +/- 3.7 micrograms/g in cornea, 3.3 +/- 0.7 micrograms/g in conjunctiva, 0.2 +/- 0.1 microgram/g in aqueous humor. After removal of the corneal epithelium concentrations were as follows: 84.2 +/- 15.8 micrograms/g, 7.3 +/- 2.3 micrograms/g, 8.6 +/- 1.9 micrograms/g respectively. Penetration in posterior ocular tissues were rather poor. In human eyes, the intracorneal concentrations were assessed in patients being operated on corneal grafts. After instillation of 5 drops, the concentration in cornea was 15.5 +/- 2.1 micrograms/g. These data show that therapeutic levels of norfloxacin can be achieved in anterior ocular tissues, which may be of help in superficial infections of the eye.

Abstract
The effects on intraocular pressure of the novel topical carbonic anhydrase inhibitor MK-927 were investigated for the first time in patients. Three drops of 2% MK-927 was administered in a two-center, double-masked, randomized, placebo-controlled, two-period crossover study in 25 patients with bilateral primary open angle glaucoma or ocular hypertension. At 4.5 hours after the dose, MK-927-treated eyes demonstrated a peak mean change of -7.7 mm Hg from a mean intraocular pressure of 27.8 mm Hg immediately before the dose; this compares with a change of -3.9 mm Hg from a mean intraocular pressure of 28.2 mm Hg when the same eyes were treated with placebo. The peak mean percent change in intraocular pressure in eyes treated with MK-927 was -26.7% at 6 hours after the dose compared with a change of -13.7% after treatment with placebo. No contralateral effect on intraocular pressure due to MK-927 was observed.
