Abstract
INTRODUCTION Cataract surgery is the most commonly performed surgery in the world, and its success depends in part on the quality of mydriasis. PURPOSE To compare, for the same eye, the pupillary dilation obtained with Mydrane® (standardized intracameral solution of 0.02% tropicamide, combined with 0.31% phenylephrine and 1% lidocaine) intraoperatively versus Mydriasert® (0.28mg tropicamide insert and 5.4mg phenylephrine) with a contact time between 45 and 60 minutes in the preoperative period. METHODS Single center prospective study from November 2016 to January 2018 at the Laveran Army Instructional Hospital in Marseille. Patients referred for surgery were dilated at the preoperative consultation with Mydriasert®. The pupillary diameter after 45-60 minutes of contact with the insert was manually measured, by two different examiners, through the "iris image" tab of the Pentacam® elevation topography. Patients were dilated on the day of their cataract surgery with 0.2cc of Mydrane® injected in the anterior chamber through a paracentesis. Thirty seconds later, prior to injection of viscoelastic, an eye photograph was taken by screen capture. The pupillary diameter was evaluated by two different examiners with to the Piximeter 5.9 metrology software. The difference in pupil dilation between Mydriasert® and Mydrane® was tested with the paired series Student t-test. RESULTS In total, 111 eyes of 82 patients were included. Mydriasert® achieved a mean pupillary dilation of 7.21±0.79mm. The mydriasis obtained with Mydrane® averaged 6.35±0.8mm. This difference of 0.86mm was statistically significant (P<0.001) with a confidence interval of 95% [-0.97; -0.74]. CONCLUSION On average, Mydrane® dilates the pupil less than Mydriasert®. However, the mydriasis obtained with Mydrane® remains comfortable for the performance of the capsulorhexis. It helps save preoperative time and affords additional anesthetic to the cataract surgery. Nevertheless, the use of Mydriasert® is beneficial when extra mydriasis is required.

Abstract
New direct oral anticoagulants (DOAC) have been approved for treatment and prevention of some thromboembolic diseases: acute and chronic phase of thromboembolic disease, deep venous thrombosis prophylaxis in orthopedic surgery and prevention of stroke in patients with atrial fibrillation. These molecules are an alternative to heparins and vitamin K antagonists. Among these, rivaroxaban (Xarelto®, Bayer Schering Pharma) is a direct factor Xa inhibitor, and dabigatran etexilate (Pradaxa®, Boehringer Ingelheim) is a direct free thrombin inhibitor. These molecules are almost the ideal anticoagulant: oral administration, few drug and food interactions, wide therapeutic target, and especially no lab monitoring. However, their use remains associated with hemorrhagic complications such as gastrointestinal, intracranial or urinary hemorrhages. We describe two clinical cases of spontaneous choroidal hemorrhage in patients treated with direct oral anticoagulants (rivaroxaban and dabigatran etexilate) for atrial fibrillation. These cases show that an ocular hemorrhagic risk exists with these drugs. Patients treated with DOAC should have the therapeutic dose adjusted based on creatinine clearance. Special monitoring should be performed in patients with age-related macular degeneration or with hypertension even though meta-analysis shows that the risk of intraocular bleeding is reduced by 22% compared with warfarin.

Abstract
INTRODUCTION The management of presbyopic patients is a medical, surgical and economic issue. We wondered which procedure, whether a Presbylasik technique called Regular Supracor or the intraocular surgery of clear lens replacement by a trifocal diffractive lens (presbyopic lens exchange [Prelex]), provided the best results (in visual acuity and satisfaction) for our hyperopic and presbyopic patients between 55 and 70. The aim of this study was to compare the safety and efficacy of the two techniques (at one week and three months) and to assess patients' quality of life. METHODS This study is a retrospective monocentric clinical trial conducted between June 2011 and March 2014, on 21 hyperopic presbyopic patients (mean age 60.9 years), in the "hôpital d'instruction des armées-Percy" (Clamart); 13 patients underwent the corneal treatment of Presbylasik (with the Intralase FS60 femtosecond laser [AMO, USA] and the Technolas 217P excimer laser [Technolas Perfect Vision, GmbH] following the Zyoptix Tissue-Saving algorithm adjusted with a nomogram and the Regular Supracor mode), and 8 patients underwent clear lens extraction (Prelex), through bimanual phacoemulsification and implantation of diffractive trifocal intraocular lenses (Finevision Micro F, PhysIOL(*)). RESULTS Mean uncorrected binocular distance and near vision visual acuity in the Supracor group were respectively 0.03 (-0.2-0.1) LogMar and 0.23 (0.06-0.36) one week postoperatively and 0.031 (-0.2-0.1) and 0,166 (0.06-0.36) three months postoperatively. In the Prelex group, the mean uncorrected one week binocular VA was 0.025 (0-0.1) for distance vision and 0.165 (0.06-0.18) for near distance and the three months visual acuity was 0 (-0.1-0.1) and 0.105 (0.06-0.18) for distance and near vision. All Prelex patients were spectacle-free at all distances, whereas 4 Supracor patients required spectacles for near vision postoperatively. Seven of 11 patients in the Supracor group and 100% of the Prelex patients were completely satisfied. Both groups experienced halos, but patients reported more halos in the Prelex group (75%). One eye required intraocular lens exchange and four eyes (16.7%) required a new corneal procedure in the Supracor group. CONCLUSION Both surgeries are safe and effective modalities in the management of hyperopic and presbyopic patients. However, the Prelex procedure seems to be more appropriate for patients over 55 years of age.

Abstract
Functional results after surgical removal of epiretinal membranes are good; most often, visual acuity improves and the macular syndrome disappears. Transconjunctival vitrectomy to perform peeling of epiretinal membrane has reduced postoperative impairment; however, the surgical complications remain the same. Epiretinal membranes are not uncommon in elderly. The surgical decision is not only based on visual acuity, but many other parameters are also considered. We provide a decision-making algorithm where the elements that suggest foregoing surgery are emphasized.

Abstract
INTRODUCTION To evaluate the tolerance and efficacy of heavy silicone oil as internal tamponade for retinal detachment surgery. PATIENTS AND METHODS Sixty-six eyes requiring heavy silicone oil for retinal detachment, with at least 1 month follow-up, were retrospectively studied. Preoperative status, surgical technique, tolerance, and anatomical and functional results were analyzed from the patient's file. Indications for heavy silicone injection were inferior retinotomy or inferior retraction in 65% of cases. PVR grade C was present in at least 63% of cases. Retinotomy was performed in 45% of cases. An exchange procedure was performed versus DKline in 65% of cases. Mean follow-up was 7 +/- 4 months. RESULTS At the end of follow-up, 59% of eyes had a completely reattached retina, 32% without internal tamponade. Another surgery was necessary in 54% of cases. During follow-up, mean intraocular pressure was normal, and there was a significant intraocular inflammation in three cases (4.5%). In seven cases of the 44 ablations of heavy silicone oil, an adherence of residual bubbles was present. Redetachment occurred after ablation for anatomical success in 41% of cases. BCVA was better than 0.05 (20/400) in 54% of cases at the end of follow-up. CONCLUSION Heavy silicone was well tolerated and seems not to be pro-inflammatory in our study. It is a good alternative to standard silicone for inferior retinotomy and inferior breaks without PVR. It is not a treatment of inferior retraction, and is not a long-term internal tamponade. During the ablation of heavy silicone oil, adherence of residual bubbles is possible, in which case a coaxial light or an endoillumination could be needed during ablation.

Abstract
PURPOSE To study the safety and efficacy of adjuvant combination therapy using 5-fluorouracil and heparin for prevention of proliferative vitreoretinopathy (PVR) during vitrectomy for retinal detachment surgery. METHODS Two consecutive groups of 30 eyes with a rhegmatogenous retinal detachment (grade C1 or more) were prospectively compared. In the study group, 5-FU and heparin were administrated in the intraoperative infusion. Clinical safety and the efficacy were regularly studied over 1 year. RESULTS In the 5-FU heparin therapy group, keratitis was more frequently observed the 1st day after surgery (p = 0.005), but not after 1 week (p = 0.54). However, conjunctival hyperemia was more severe after 1 and 7 days (p = 0.04). In both groups, no differences were found concerning intraocular pressure, postoperative hemorrhage or inflammatory reaction (flare) of the anterior chamber and the aspect of the eyelids (p > or = 0.14). The number of reoperations resulting from PVR, after 1 month and 1 year, was not significantly different between the two groups (p > or = 0.3). The reattachment rate and visual acuity (BSCVA) were not statistically different after 1 year (p > or = 0.12). CONCLUSION Adjuvant combination therapy using 5-FU and heparin seems to be safe. However, its efficacy needs to be demonstrated by larger studies including eyes presenting a lower grade of PVR (grade B).

Abstract
This article summarizes our current knowledge on two types of retinal diseases: hereditary retinal degeneration and wet aged-related macular degeneration. Our understanding of retinal physiopathology in hereditary retinal degeneration and the successful experimental therapeutic results on animal models call for a new approach to these patients to prepare future clinical trials. Longitudinal follow-up of the functional alteration rhythm based on international standards and by expert centers is an essential prerequisite to including these patients in future clinical trials. Creating international databases that include data on follow-up using electrophysiological, psychophysical and morphological analyses would require standards defining how each of these procedures should be carried out. Furthermore, the relevance and value of the various examinations would then be evaluated in a longitudinal manner. The repeated use of these procedures in the various centers would bring to light any limitations these techniques may have for use in prospective studies. Continuous re-evaluation of these investigative techniques will therefore be necessary, a crucial factor in the preparation of multicenter clinical studies. The inclusion of patients phenotyped at different centers would require that certification procedures be set up for these centers. A great leap forward, clinical trials on new antiangiogenic approaches for the treatment of neovascular AMD are currently underway. The reasons for the switch between the neovascular and atrophic forms of AMD are as yet unknown, but these new approaches are based on the events that occur sequentially during the angiogenic response.

Abstract
The alpha v beta (alpha(v)beta5) heterodimer has been implicated in many biological functions, including angiogenesis. We report the beta5 gene expression pattern in embryonic and foetal mouse tissues as determined by Northern blotting and in situ hybridization. During the earliest stages, beta5 mRNA is widespread in the mesoderm. During later developmental stages, it remains mostly confined to tissues of mesodermal origin, although probable inductive effects trigger shifts of beta5 gene expression from some mesenchymatous to epithelial structures. This was observed in the teeth, skin, kidneys, and gut. Of physiological importance is the beta5 labeling in the developing cardiovascular and respiratory systems and cartilages. Furthermore, early beta5 gene expression was observed within the intra- and extraembryonic sites of hematopoiesis. This suggests a major role for beta5 in the hematopoietic and angiogenic stem cells and thus in the development of the vascular system. Later, the beta5 gene was expressed in endothelial cells of the vessels developing both by angiogenesis and vasculogenesis in the lung, heart, and kidneys. Moreover, the beta5 hybridization signal was detected in developing cartilages but not in ossified or ossifying bones. beta5-Integrin is a key integrin involved in angiogenesis, vasculogenesis, hematopoiesis, and bone formation.

Abstract
We report a structural analysis at the molecular level of MOMP from Campylobacter, a gram-negative bacteria responsible for diarrhea. The corresponding gene was cloned and sequenced. Sequence comparison of seven MOMP sequences (three extracted from protein databases and four determined in this study) from distinct strains indicated alternation of preserved and divergent regions. No other significant sequence similarities could be detected. Comparison of MOMP with the crystal structures of other porins strongly suggested that it might adopt a similar fold and revealed the conservation of the monomer-monomer interface. The conservation clustered in the regions comprising or interacting with the loop L2. On the contrary, strands not involved in the interface are more divergent. Proteolysis assays and biochemical treatment supported the proposed model. Our study suggested that MOMP belong to the maltoporin super-family sharing common structural motifs. In view of this model we discuss its specificity and its global stability.

Abstract
Intravitreal injections are currently used in the rat to introduce a therapeutic factor in the eye, especially for experimental treatments of retinal degenerations. The injected volume and its location can influence the quantification of results. We have investigated the quantitative effect of a single intravitreal injection in rats at different ages and for different volumes. Albinos rats aged three weeks or two months received intravitreal injections of 1, 3, 5 or 10 microl China ink. Animals were sacrificed immediately after injection, eyes were enucleated, fixated, embedded in paraffin and microtomy was performed in a sagittal plane. Regularly spaced sections were analyzed to reconstruct the vitreous and injected dye volumes. The measured vitreous volume was 6.76 +/- 0.37 mm(3) in three weeks old rats and 13.36 +/- 0.64 mm(3) in two months old rats. Mean intravitreal ink volumes immediately after injection were 0.8 mm(3) for 1 ml injections, 2 mm( 3) for 3 ml, 2.3 to 2.6 mm(3) for 5 microl and 3.2 mm(3 ) for 10 microl. The percentage of vitreous volume involved by the injection ranged from 4.4% to 33.2%. The injected volume is limited by the large lens size of the rat. Extraocular loss of injected solution increases for higher injected volumes, with larger standard deviations. In this model, the dye tends to localize behind the lens. A 3 or 5 microl volume appears to have the best reproducibility with minimum loss of solution.

Abstract
The RCS rat presents an autosomal recessive retinal pigment epithelium dystrophy characterized by the outer segments of photoreceptors being phagocytosis-deficient. A systematic genetic study allowed us to restrict the interval containing the rdy locus to that between the markers D3Mit13 and D3Rat256. We report the chromosomal localization of the rat c-mer gene in the cytogenetic bands 3q35-36, based on genetic analysis and radiation hybrid mapping. Using a systematic biocomputing analysis, we identified two strong related candidate genes encoding protein tyrosine kinase receptors of the AXL subfamily. The comparison of their expression patterns in human and mice tissues suggested that the c-mer gene was the best gene to screen for mutations. RCS rdy- and RCS rdy+ cDNAs were sequenced. The RCS rdy- cDNAs carried a significant deletion in the 5' part of the coding sequence of the c-mer gene resulting in a shortened aberrant transcript encoding a 20 amino acid peptide. The c-mer gene contains characteristic motifs of neural cell adhesion. A ligand of the c-mer receptor, Gas6, exhibits antiapoptotic properties.

Abstract
We describe a case of the SHORT syndrome and compare it with previously published cases. This six-year-old girl shows nearly all the typical manifestations reported in patients with the SHORT syndrome, including lipoatrophy, minor facial anomalies, Rieger anomaly, and short stature. However, she also suffers from high hyperopia and astigmatism associated with poor visual acuity.

Abstract
Based on the K8/JTS-1-mediated transfection technique, we developed an in vivo protocol for an efficient transfer of plasmid DNA to ocular cells. As determined with condensed plasmids containing reporter genes for either beta-galactosidase (pcDNA-lacZ) or enhanced green fluorescent protein (pREP-EGFP), the immortalized human retinal epithelial cells RPE D407 and human embryonic kidney 293 cells can be transfected with typical efficiencies of 11 and 19%, respectively. Unlike 293 cells, RPE D407 cells had a reduced viability on transfection with both plasmids. In vivo, subretinal injections of DNA-K8/JTS-1 complexes revealed reporter gene expression in choroidal and RPE cells of normal pink-eyed Royal College of Surgeons (RCS) rats. The validity of this transfection technique in terms of retinal cell survival in RCS rats was then examined by using pREP-hFGF2 plasmid, which encodes the human basic fibroblast growth factor isoforms (hFGF2). Subretinal injection of pREP-hFGF2-K8/JTS-1 complexes into 3-week-old dystrophic RCS rat eyes reveals a delayed photoreceptor cell degeneration 60 days postinjection. In this case, the average analyzed field points with delayed cell dystrophy represent 14 to 17% of the retinal surface as compared with 2.6 and 4% in pREP5beta and vehicle-injected eyes, respectively. Peptide-mediated in oculo transfection thus appears to be a promising technique for the treatment of retinal cell and photoreceptor degenerations.

Abstract
Mutations in human BIGH3 (TGFB1), a gene identified after treatment of an adenocarcinoma cell line with TGF-beta, have been observed in patients with granular Groenouw type I, Reis-Bücklers, Thiel-Behnke, Avellino, and Lattice type I and IIIa, six autosomal dominant corneal dystrophies linked to chromosome 5q. In order to gain insight into the physiological role of this gene, we characterized the genomic structure of the mouse Bigh3 and its expression in murine embryos. The gene spans 30 kb on mouse chromosome 13 and has 17 exons. Embryonic expression of Bigh3 is observed in the mesenchyme of the first and second branchial arches as early as dpc 11.5 and is particularly strong in the mesenchyme of numerous tissues throughout all the development stages. In fetal eye, the expression is first seen at 11.5 dpc in the mesenchyme surrounding the optic stalk, extends toward the sclera and choroid by 14.3 dpc and reaches the cornea by 17.5 dpc. Because the physiological role of BIGH3/Bigh3 is still largely unknown, embryonic expression in organs like heart, vessels, and intestine may help to identify new functions which could be searched for in patients and in knock-out animal models. The characterization of the murine structure is a prerequisite for the making of such models.

Abstract
BACKGROUND Experimental therapeutic approaches to retinal degenerations often require the subretinal injection of a therapeutic agent. The injected volume and the age of the animal can influence the proportion of the retinal surface affected by the subretinal injection. We have investigated the quantitative effect of a single injection in the subretinal space. METHODS Normal and Royal College of Surgeons rats aged 1 week, 3 weeks or 2 months received subretinal transscleral injections of 1, 3, 5 or 10 microl China ink. After 24 h, animals were killed, injected eyes were enucleated and fixated, and the retinas flattened. An image analyzing program was used to measure the total retinal surface and the retinal surface affected by the dye. RESULTS The mean retinal surface affected by the injection ranged from 5.24+/-2.76 mm2 to 14.8+/-2.3 mm2, depending on animal age and injected volume. The injection affected 8.79+/-0.89 to 36.9+/-8.13% of total retinal surface. There was no statistically significant difference between normal and Royal College of Surgeons rats. Intravitreal leakage of the dye was more frequent with increasing injection volumes. CONCLUSION The retinal surface affected by a single subretinal injection increases with the injected volume, but this increase is not proportional. Higher volumes lead to a loss of injected solution, either in the vitreous body or through the sclerotomy. In 2-month-old rats, a 3-microl subretinal injection appears to have the best reproducibility, with 20-30% of retinal surface covered by the injected dye.
