Abstract
PURPOSE The goal of this study was to investigate the safety and efficacy of the intravitreal dexamethasone implant (DI) for patients with diabetic macular edema (DME) in real life. METHODS We conducted a monocentric retrospective analysis of the change in visual acuity and central macular thickness (CMT) after intravitreal injection of the DI at peak efficacy (2 months after injection) as well as the timing of reinjections and complications in patients with a loss of vision due to DME. RESULTS Forty eyes of 33 patients were included, with a mean follow-up of 12.6 months. Thirty percent of the eyes experienced an increase in best corrected visual acuity (BCVA)>15 letters at peak efficacy (P<0.05) after each ID injection. Treatment-naive patients had a sustained response after Ozurdex injection, with better visual acuity at 3 months (P=0.02) and 4 months (P=0.04) than non-naïve patients and better visual acuity at 6 months despite identical baseline visual acuity (P<0.05). Anatomical efficacy was good, with approximately 60% of patients with CMT<300 microns at peak efficacy after each injection of ID. Thirty percent of eyes demonstrated ocular hypertension (OHT)>25mmHg at peak efficacy, and 12.5% of eyes required cataract surgery during follow-up. CONCLUSION The DI has good functional and anatomic efficacy in these patients, with a good safety profile. Treatment-naïve patients with more recent DME had a more sustained increase in visual acuity after the injections and better visual recovery at 6 months. This encourages us to initiate DI therapy early if there is no response to anti-vascular endothelial growth factor (anti-VEGF) treatment.

Abstract
PURPOSE The aim of this study was to investigate the sustained intraocular pressure (IOP) elevation after repeated anti-VEGF intravitreal injections (IVI) in patients with diabetic macular edema (DME). METHODS A retrospective study included 140 eyes without prior glaucoma, treated with at least three anti-VEGF injections for DME between 2012 and 2016. IOP elevation was defined by an increase above baseline IOP by ≥6 mmHg. Baseline IOP was defined as the mean of IOP values before treatment initiation. Three groups were differentiated: group 1 without IOP elevation, groups 2 and 3 with IOP elevation and IOP <21 mmHg (group 2) and ≥21 mmHg (group 3). Rate and several risk factors of IOP elevation were assessed and compared between the three groups. RESULTS IOP elevation occurred in ten eyes (7.1%). IOP was <21 mmHg in six eyes and ≥21 mmHg in four eyes. Statistically significant associations were found between IOP elevation and the number of injections, and HbA1c level. Two patients required local hypotonic treatment. CONCLUSIONS In a real-life setting, we confirmed in eyes with center-involved DME without prior glaucoma or IOP elevation that repeated anti-VEGF IVI may increase the risk of sustained IOP elevation in about 7% of eyes.

Abstract
PURPOSE To assess French practice patterns in the treatment of diabetic macular edema (DME). METHODS A 31-item survey investigating practice patterns in the diagnosis and management of DME was e-mailed in March 2015 to retina specialist members of the French-speaking Retina Specialist Society. During this time frame, only ranibizumab was reimbursed for this indication. For each question concerning the choice of treatments, respondents were asked to assume that all treatments having market approval were also reimbursed. Answers were analyzed anonymously by Evalandgo software. RESULTS Ninety-five specialists answered the survey. Two thirds of them initiated an intravitreal treatment for DME for a loss of vision greater than 0.5 (Monoyer scale). The three determining factors for treatment choice were potential VA improvement, expected retinal anatomic improvement, and patient availability for monthly follow-up. For central DME in phakic or pseudophakic eyes, the first choice of intravitreal (IVT) treatment was ranibizumab, even assuming that all drugs approved by French authorities (HAS) were reimbursed by the health care system. Eighty-five percent of retinal specialists propose bilateral intravitreal injections the same day for the same patient. CONCLUSION Most of the specialists initiate DME treatment for a VA>0.5 in France. Eighty-five percent of them perform bilateral intravitreal injections on the same day in the case of bilateral DME.

Abstract
Gene flow is particularly frequent in the genus Quercus (oaks), especially between closely related species. We focus here on Quercus ilex and the cork-producing Quercus suber, which occasionally hybridize although they are phylogenetically markedly separated. Morphological observations were combined with both allozymic and chloroplastic diagnostic markers to characterize hybridization and introgression and to infer their dynamics in two French regions (French Catalonia and Provence), which are separated by several hundred kilometres. Some hybrids were found in both regions, indicating recent hybridization events. As expected from previous studies, most hybrids resulted from female symbol Q. ilex x male symbol Q. suber crosses, but our data showed that the reciprocal cross is also possible. Partial independence between nuclear and chloroplastic introgression was observed in the two species. Nuclear introgression was limited in both species and both regions, with no preferred direction. In Provence, chloroplastic introgression was very rare in both species. Conversely, all Q. suber individuals from French Catalonia were introgressed by Q. ilex chlorotypes. This might be explained by introgression in the Iberian Peninsula antedating the first occurrence of the two species in French Catalonia. We also observed a new chlorotype that was created locally, and was exchanged between the two species. However, the two species still remain genetically differentiated. The dynamics and complexity of exchanges and the factors determining them (including human management of Q. suber) are discussed.

Abstract
Hybridisation is a potent force in plant evolution, although there are few reported examples of stabilised species that have been created through homoploid hybridisation. We focus here on Quercus afares, an endemic North African species that combines morphological, physiological and ecological traits of both Q. suber and Q. canariensis, two phylogenetically distant species. These two species are sympatric with Q. afares over most of its distribution. We studied two Q. afares populations (one from Algeria and one from Tunisia), as well as several populations of both Q. suber and Q. canariensis sampled both within and outside areas where these species overlap with Q. afares. A genetic analysis was conducted using both nuclear (allozymes) and chloroplastic markers, which shows that Q. afares originates from a Q. suber x Q. canariensis hybridisation. At most loci, Q. afares predominantly possesses alleles from Q. suber, suggesting that the initial cross between Q. suber and Q. canariensis was followed by backcrossing with Q. suber. Other hypotheses that can account for this result, including genetic drift, gene silencing, gene conversion and selection, are discussed. A single Q. suber chlorotype was detected, and all Q. afares individuals displayed this chlorotype, indicating that Q. suber was the maternal parent. Q. afares is genetically, morphologically and ecologically differentiated from its parental species, and can therefore be considered as a stabilised hybrid species.
