Efficacy of the DRL orthokeratology lens in slowing axial elongation in French children. Front Med (Lausanne) 2024; 10:1323851. [PMID: 38239610 PMCID: PMC10794606 DOI: 10.3389/fmed.2023.1323851] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/18/2023] [Accepted: 12/11/2023] [Indexed: 01/22/2024] Open
Abstract
Background This study aims to assess and compare the impact of Orthokeratology Double Reservoir Lens (DRL) versus Single Vision Lenses (SVL) on axial elongation and anterior chamber biometric parameters in myopic children over a 6- and 12-month treatment period in France. Methods A retrospective study involving 48 patients aged 7 to 17 years, who underwent either orthokeratology treatment or single-vision spectacle correction, was conducted. Changes in refractive error, axial length, and anterior chamber depth were examined. Results Twenty-five patients comprised the Orthokeratology (OK) group, while twenty-three were in the control group (single-vision spectacle group). Significant increases in mean axial length were observed over time in both the control (0.12 ± 0.13 mm and 0.20 ± 0.17 mm after 6 and 12 months, respectively; F (2,28.9) = 27.68, p < 0.001) and OK groups (0.02 ± 0.07 mm and 0.06 ± 0.13 mm after 6 and 12 months, respectively; F (2,29.1) = 5.30, p = 0.023). No statistically significant differences in axial length were found between male and female children (p > 0.620). Age-specific analysis revealed no significant axial elongation after 12 months in the 14-17 years group in the OK group. Anterior biometric data analysis at 6 and 12 months showed statistical significance only for the DRL group. Conclusion Orthokeratology resulted in an 86 and 70% reduction in axial elongation after 6 and 12 months of lens wear, respectively, compared to the single-vision spectacles group. Myopia progression was more pronounced in younger children, underscoring the importance of initiating myopia control strategies at early ages.

Intravitreal Injection of Bevacizumab for the Prevention of Postoperative Proliferative Vitreoretinopathy in High-Risk Patients Selected by Laser Flare Photometry. Ophthalmologica 2023; 246:306-313. [PMID: 37769629 DOI: 10.1159/000533750] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/30/2023] [Accepted: 08/05/2023] [Indexed: 10/03/2023]
Abstract
INTRODUCTION To evaluate the effect of an intravitreal injection of bevacizumab at the time of rhegmatogenous retinal detachment (RRD) surgery, on postoperative proliferative vitreoretinopathy (PVR) in high-risk patients selected by laser flare photometry. METHODS This single-center observational retrospective cohort study included 137 consecutive patients who underwent pars plana vitrectomy and gas tamponade for primary RRD with increased aqueous flare between July 2016 and June 2021. From June 2019, an intravitreal injection of bevacizumab was administered as an adjunct to RRD repair. Patients who underwent surgery before this time and who did not receive intravitreal bevacizumab served as controls. The main outcome was the rate of retinal redetachment due to PVR. RESULTS The median flare value was 22.0 (16.5-36.5) pc/ms in the control group and 28.2 (19.7-41.0) pc/ms in the bevacizumab group (p = 0.063). Eyes treated with bevacizumab were more likely to have macula-off RRD (p = 0.003), grade B PVR (p = 0.038), and worse visual acuity (p = 0.004) than controls. The rate of PVR redetachment was significantly lower in the bevacizumab group (11.1%) than in the control (30.1%) (p = 0.012). This difference was more pronounced after adjusting for potential confounding factors (p = 0.005); the risk of developing PVR was 4.5-fold higher in controls (95% CI, 1.6-12.8). After adjustment, the final median visual acuity was also significantly higher in eyes treated with bevacizumab (p = 0.025). CONCLUSION This pilot study provides preliminary evidence that bevacizumab may reduce the risk of PVR-related recurrent RRD and improve visual outcomes in high-risk patients selected by laser flare photometry.

Dissociated Optic Nerve Fiber Layer Appearance after Macular Hole Surgery: A Randomized Controlled Trial Comparing the Temporal Inverted Internal Limiting Membrane Flap Technique with Conventional Peeling. Ophthalmol Retina 2023; 7:227-235. [PMID: 36109006 DOI: 10.1016/j.oret.2022.09.002] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/12/2022] [Revised: 09/01/2022] [Accepted: 09/06/2022] [Indexed: 10/14/2022]
Abstract
PURPOSE To evaluate the effect of the temporal inverted internal limiting membrane (ILM) flap technique compared with that of conventional ILM peeling on the extent of the dissociated optic nerve fiber layer (DONFL) and retinal sensitivity in patients undergoing macular hole (MH) surgery. DESIGN Single-center, prospective, open-label, randomized controlled clinical trial. PARTICIPANTS Patients requiring vitrectomy for MHs sized > 250 μm. METHODS Patients were randomly assigned (1:1) to 1 of the following 2 groups: (1) the control group undergoing standard ILM peeling and (2) the experimental group (flap group) undergoing the temporal inverted ILM flap technique. MAIN OUTCOME MEASURES The primary outcome measure was the total DONFL score at 3 months after surgery. Important secondary outcomes were microperimetry results, primary MH closure rate, external limiting membrane (ELM) and ellipsoid zone (EZ) recovery rates, and best-corrected visual acuity (BCVA). RESULTS Sixty-five patients were recruited between February 2018 and July 2020; primary outcome data were available for 60 patients. The median DONFL score was 7.0 (3.0-12.5) in the control group and 5.0 (1.5-8.5) in the flap group at 3 months after surgery (P = 0.145). The focal depressions characteristic of the DONFL were limited to the temporal side of the fovea in the flap group, whereas they were found all around the fovea in the control group on spectral-domain OCT images. The MH closure rate (P = 1), EZ and ELM recovery rates (P = 0.252), and BCVA (P = 0.450) were similar between the 2 groups. The 3-month overall median retinal sensitivity (MRS) (P = 0.142) and MRS improvement (P = 0.916) in the control group were comparable with those observed in the flap group. In addition, there was no significant difference between the 2 techniques when considering the temporal area (P = 0.105) or the nasal area (P = 0.468). CONCLUSIONS The temporal inverted ILM flap technique reduced the extent of the DONFL by preserving the nasal part of the fovea. However, the overall DONFL score was similar between the 2 techniques. In addition, the MRS and BCVA did not differ from those obtained after complete ILM peeling.

Association of microvasculature changes with visual outcomes after successful retinal detachment surgery. Ophthalmol Retina 2022; 6:886-892. [PMID: 35525534 DOI: 10.1016/j.oret.2022.04.020] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/30/2021] [Revised: 04/04/2022] [Accepted: 04/20/2022] [Indexed: 10/18/2022]
Abstract
PURPOSE To evaluate macular microvascular changes and their correlation with visual outcomes after rhegmatogenous retinal detachment (RRD) surgery. DESIGN Retrospective case series PARTICIPANTS: Seventy-four eyes successfully operated for RRD were included in the study. METHODS The area of the foveal avascular zone in the superficial capillary plexus, the vessel density in the superficial capillary plexus (SCP), deep capillary plexus (DCP), and choriocapillary plexus (CCP) were evaluated using optical coherence tomography angiography (OCTA) at 1 and 6 months postoperatively. The fellow eyes were used as controls for comparison. MAIN OUTCOME MEASURES The correlation between OCTA parameters and postoperative best-corrected visual acuity (BCVA) was assessed using a hybrid linear mixed model. We also analyzed the relationship between OCTA parameters and the integrity of the external limiting membrane (ELM) and ellipsoid zone (EZ) of photoreceptors. RESULTS The median vessel density in the DCP was significantly decreased in RRD eyes at 1 month (p=0.019), but gradually improved over time to reach the value of the fellow eyes at 6 months (p=1). There was no significant difference between the 2 groups in median foveal avascular zone area, vessel density in the SCP and in the CCP (p=0.579, p=0.618, p=0.068 and p=0.819, p=1 and p=1, respectively) at both 1 and 6 months postoperatively. Postoperative BCVA was positively correlated with the vessel density in the DCP (p=0.009) in multivariate analysis. Eyes with low 1-month vessel density in the DCP tended to have worse final BCVA (p=0.067). There was no correlation between the vessel density in the DCP and ELM and/or EZ integrity at both 1 (p=0.156) and 6 months postoperatively (p=0.161). Eyes with intact ELM and EZ at 6 months, however, had significantly higher 1-month vessel density in the DCP than those with disrupted ELM and/or EZ (p=0.027). CONCLUSION The vessel density in the DCP was affected in RRD eyes as well as associated with postoperative BCVA and the restoration of photoreceptor layers. It might thus serve as a predictor for visual recovery following successful RRD surgery.

Effect of Duration of Silicone Oil Tamponade on Retinal Structure after Rhegmatogenous Retinal Detachment Surgery. Ophthalmologica 2021; 245:144-151. [PMID: 34929691 DOI: 10.1159/000519520] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/01/2021] [Accepted: 09/06/2021] [Indexed: 11/19/2022]
Abstract
PURPOSE The aim of the study was to investigate the effect of tamponade duration on retinal changes induced by silicone oil (SO) in patients who underwent successful rhegmatogenous retinal detachment (RRD) surgery. METHODS Retrospective comparative case series of 68 patients who underwent SO tamponade for RRD. Patients were divided into 2 groups based on timing of SO removal: <6 months (group 1, n = 34) versus ≥6 months (group 2, n = 34). The main outcome measure was the change in central macular, inner, and outer retinal layer thickness (CMT, IRLT, and ORLT) before and after SO removal (SOR). RESULTS The median tamponade duration was 4 [Clin Ophthalmol. 2016;10:471-6, Zhonghua Yan Ke Za Zhi. 1997 Jan;33(1):39-41] months in group 1 and 8 [Arch Ophthalmol. 1994 Jun;112(6):778-85, Retina. 2004 Dec;24(6):871-7] months in group 2 (p < 0.001). The mean CMT significantly increased from 245.3 ± 22.2 μm and 238.8 ± 41.6 μm under SO to 281.3 ± 60.2 μm and 259.0 ± 43.5 μm after SOR in group 1 (p = 0.009) and in group 2 (p = 0.007), respectively. Automated segmentation measurement revealed a significant increase in mean IRLT (p = 0.014 and p = 0.013) but no change in mean ORLT (p = 0.080 and p = 0.257) in both groups. After adjustment, there was no difference between the 2 groups in terms of mean final CMT, IRLT, and ORLT and mean retinal thickness changes after SOR. There was also no correlation between the tamponade duration and macular microstructural changes or visual recovery. CONCLUSION SO tamponade causes a thinning of all retinal layers, mainly affecting the inner retinal layer. However, these changes resolved following SO extraction and were not affected by longer tamponade duration.

Insulin inhibits inflammation-induced cone death in retinal detachment. J Neuroinflammation 2020; 17:358. [PMID: 33243251 PMCID: PMC7694924 DOI: 10.1186/s12974-020-02039-1] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/22/2020] [Accepted: 11/17/2020] [Indexed: 01/12/2023] Open
Abstract
BACKGROUND Rhegmatogenous retinal detachment (RD) involving the macula is a major cause of visual impairment despite high surgical success rate, mainly because of cone death. RD causes the infiltration of activated immune cells, but it is not clear whether and how infiltrating inflammatory cells contribute to cone cell loss. METHODS Vitreous samples from patients with RD and from control patients with macular hole were analyzed to characterize the inflammatory response to RD. A mouse model of RD and retinal explants culture were then used to explore the mechanisms leading to cone death. RESULTS Analysis of vitreous samples confirms that RD induces a marked inflammatory response with increased cytokine and chemokine expression in humans, which is closely mimicked by experimental murine RD. In this model, we corroborate that myeloid cells and T-lymphocytes contribute to cone loss, as the inhibition of their accumulation by Thrombospondin 1 (TSP1) increased cone survival. Using monocyte/retinal co-cultures and TSP1 treatment in RD, we demonstrate that immune cell infiltration downregulates rod-derived cone viability factor (RdCVF), which physiologically regulates glucose uptake in cones. Insulin and the insulin sensitizers rosiglitazone and metformin prevent in part the RD-induced cone loss in vivo, despite the persistence of inflammation CONCLUSION: Our results describe a new mechanism by which inflammation induces cone death in RD, likely through cone starvation due to the downregulation of RdCVF that could be reversed by insulin. Therapeutic inhibition of inflammation and stimulation of glucose availability in cones by insulin signaling might prevent RD-associated cone death until the RD can be surgically repaired and improve visual outcome after RD.

Prevalence and risk factors for outer retinal layer damage after macula-off retinal detachment. Br J Ophthalmol 2019; 104:660-665. [PMID: 31462417 DOI: 10.1136/bjophthalmol-2019-314236] [Citation(s) in RCA: 16] [Impact Index Per Article: 3.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/10/2019] [Revised: 07/22/2019] [Accepted: 08/12/2019] [Indexed: 11/04/2022]
Abstract
PURPOSE To report the prevalence of outer retinal layer (ORL) damage after macula-off rhegmatogenous retinal detachment (RRD) surgery and to determine its associated preoperative risk factors. METHODS 253 eyes successfully operated for macula-off RRD were included in the study. The integrity of the external limiting membrane (ELM), ellipsoid zone (EZ) and cone interdigitation zone (CIZ) of the photoreceptors was assessed at 1 month and 6 months using spectral-domain optical coherence tomography. Risk factors were analysed using univariate and multivariate logistic regression. The correlation between ORL integrity and visual outcomes was also evaluated. RESULTS CIZ, EZ and ELM defects were found in, respectively, 198 (93.4%) eyes, 100 (47.2%) eyes, 64 (30.2%) eyes at 1 month and in 160 (63.2%) eyes, 44 (17.4%) eyes and 18 (7.1%) eyes at 6 months. In multivariate analysis, duration of macular detachment was the only factor associated with ORL damage at 6 months (p=0.007). Best-corrected visual acuity significantly improved from 0.5±0.3 at 1 month to 0.3±0.3 logarithm of minimal angle of resolution at 6 months (p<0.001) and was strongly correlated with the number of affected bands (p<0.001). CONCLUSION Prevalence of outer retinal band defects substantially decreased through the study period, confirming the ability of photoreceptors to recover over time. However, shorter interval to surgery and better visual outcomes were significantly associated with fewer defects within the ORL at 6 months. These findings suggest that earlier surgery may limit RRD-associated photoreceptor degeneration and improve the patient's visual prognosis.

Abstract
PURPOSE To investigate the clinical benefit of internal limiting membrane (ILM) peeling as a surgical adjunct in the repair of primary retinal detachment (RD) complicated by grade B proliferative vitreoretinopathy (PVR). DESIGN Retrospective, interventional, comparative case series. METHODS Setting, study population, observationalprocedures and Main outcome measures. SETTING Institutional. STUDY POPULATION Seventy-five consecutive patients who underwent vitrectomy for primary macula-off RD complicated by grade B PVR. OBSERVATIONAL PROCEDURES Patients were divided into an ILM peeling (Group P) and a no ILM peeling group (Group NP). MAIN OUTCOME MEASURES Anatomic success rate, best-corrected visual acuity, and spectral-domain optical coherence tomography (SD-OCT) characteristics were collected at 1 and 6 months. RESULTS In all, 37 eyes with ILM peeling were included in Group P and 38 eyes without ILM peeling were included in Group NP. The anatomic success rate after single surgery was higher in Group P (89%) than in Group NP (66%, P = .03). Mean final visual acuity was 0.41 ± 0.40 logMAR in Group P vs 0.43 ± 0.22 logMAR in Group NP (P = .82). We found no epiretinal membrane (ERM) formation in Group P, whereas 5 cases of ERM (20%) were detected in Group NP (P = .012). The 2 groups did not differ in terms of cystoid macular edema occurrence, macular thickness, or photoreceptor damage. CONCLUSIONS ILM peeling during vitrectomy in macula-off RD complicated by grade B PVR reduces the need for a second surgery for redetachment or macular pucker.

Abstract
This study was designed to improve the understanding of the mechanisms that govern the origin of retinal detachment (RD) by examining the quantitative composition of proteins in the subretinal fluid (SRF). Inflammation proteins and immunoglobulins (Ig) were titrated from SRF and sera in 25 patients with RD The following concentrations were found in SRF: total proteins 16 g/l; albumin 12.6 g/l; pre-albumin 0.37 g/l; transferin 1.8 g/l in 68% of cases; haptoglobin and alpha 2 macroglobin were present in only one SRF: alpha 1 antitrypsin 0.86 g/l in 48%; orosomucoid 0.57 g/l in 32%; IgG 2 g/l in 52%; Ig A 0.17 g/l in 88% and IgM 15.9 mg/l in 56%. Correlations were found between the duration of detachment and the concentration of total proteins (p < 0.01). The extent of RD was correlated with the concentration of IgG or IgA in the SRF (p < 0.01). These findings suggest that the correlation between the Ig concentration and the extent of RD is an argument for the participation of choriocapillaris in the genesis of SRF

Abstract
PURPOSE To investigate aqueous flare as a preoperative predictor for later proliferative vitreoretinopathy (PVR) development in patients with rhegmatogenous retinal detachment (RD) and to determine the validity of this measurement in patients at low clinical risk for postoperative PVR. METHODS This study included 100 eyes of 100 patients who underwent surgery for primary RD. Aqueous flare was determined preoperatively with a laser flare-cell meter (Kowa FM-500, Kowa Company Ltd, Tokyo, Japan). Patients were followed for at least 6 months postoperatively. Failures related to PVR were recorded for statistical analysis. RESULTS Twenty eyes (20%) developed PVR postoperatively. Preoperative flare values in these eyes were significantly higher than in eyes with no redetachment (48.12 ± 61.24 versus 17.74 ± 29.63 photon counts per millisecond (pc/ms), p = 0.002). The odds ratio for PVR development with flare values >15 pc/ms was 12.3 (p < 0.0001, 95% confidence interval, 3.54-42.59). Of 54 eyes at low clinical risk for postoperative PVR, five developed PVR postoperatively. Flare values were significantly higher in these eyes (25.30 ± 7.10 pc/ms) than in eyes with no redetachment (12.44 ± 10.16 pc/ms, p = 0.008). Using logistic regression, the odds ratio of PVR redetachment risk increased by the factor 1.078 per 1 pc/ms of flare value (95% CI, 1.01-1.15). CONCLUSION Preoperative aqueous flare is a strong predictive factor for PVR redetachment. The laser flare-cell meter provides a fast and safe tool to accurately identify patients at risk for postoperative PVR, especially when clinical examination did not predict this risk.

Abstract
BACKGROUND The study aimed to evaluate outcomes of epiretinal membrane (ERM) peeling in patients with asteroid hyalosis (AH) and to compare them with those from controls without AH. METHODS This is a retrospective matched cohort study of 1,104 consecutive patients who underwent surgery for ERM between January 2004 and February 2014. Patients with AH were included in the study group and were matched for preoperative visual acuity, age, gender, date of surgery, and axial length with control patients without AH selected from the same cohort. The best-corrected visual acuity (BCVA) and central macular thickness (CMT) on optical coherence tomography were measured at baseline and postoperatively with a minimum follow-up period of 12 months. RESULTS A total of 44 patients were included in the AH group and 44 in the control group. The mean initial BCVA was 0.53 ± 0.21 LogMAR for the AH group vs. 0.49 ± 0.20 LogMAR for the control group, and the mean initial CMT was 419 ± 74 vs. 423 ± 75 µm, respectively. During the follow-up, no significant difference was found regarding the final BCVA at 6 months (0.23 ± 0.14 vs. 0.24 ± 0.17) LogMAR (p = 0.87) and 12 months (0.16 ± 0.09 vs. 0.17 ± 0.12) LogMAR (p = 0.92), despite a tendency toward slower visual recovery for the AH group at 1 month, with a mean BCVA of 0.36 ± 0.12 vs. 0.28 ± 0.18 LogMAR (p = 0.08). No difference was found regarding the progression of CMT at 1.6 and 12 months with a mean CMT of 396 ± 47 vs. 378 ± 55 µm (p = 0.39), 356 ± 39 vs. 365 ± 41 µm (p = 0.48), and 349 ± 68 vs. 352 ± 53 µm (p = 0.87), respectively. CONCLUSION Vitrectomy with ERM peeling in patients with AH was beneficial and showed similar functional and anatomical outcomes in both groups. AH does not seem to affect visual improvement or the complication rate after ERM peeling. Therefore, the indications for vitrectomy in case of ERM should not be prompted by the presence of AH.

Abstract
PURPOSE The host immune reaction during endophthalmitis, studied in particular through the intraocular cytokine network, is essential for the comprehension of the disease and the development of new therapies. Therefore, the purpose of this study was to elucidate the cytokine composition of aqueous humor during endophthalmitis. METHODS In a multicenter case-control study, forty-nine patients with postoperative endophthalmitis and 60 controls (cataract surgery) were included. Visual acuity, local inflammatory grading, medical history and intraocular levels of 27 cytokines and chemokines (measured by multiplex immunoassay) were recorded. RESULTS During endophtalmitis, an increase in total cytokines was observed. The raise of Th1 cytokines was particularly noticeable. Chemokines, such as IL-8, MIP-1 β, MCP-1, G-CSF and IP-10, also increased. Pearson's correlation analyses showed a poor visual prognosis with high levels of IL-8, MCP-1 and VEGF and a low level of IL-10 at admission. CONCLUSION An increase in inflammatory cytokines is noticeable during endophthalmitis, with a particular emphasis on IL-8, MCP-1 and VEGF. Targeted anti-inflammatory and anti-VEGF treatments may be of interest in the future.

Postoperative Ocular Inflammation: A Single Subconjunctival Injection of XG-102 Compared to Dexamethasone Drops in a Randomized Trial. Am J Ophthalmol 2017; 174:76-84. [PMID: 27810317 DOI: 10.1016/j.ajo.2016.10.012] [Citation(s) in RCA: 33] [Impact Index Per Article: 4.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/08/2016] [Revised: 10/21/2016] [Accepted: 10/22/2016] [Indexed: 10/20/2022]
Abstract
PURPOSE To evaluate the efficacy and safety of XG-102 (brimapitide) compared to dexamethasone eye drops in the treatment of postoperative ocular inflammation. DESIGN Multicenter, randomized, parallel group, double-masked, noninferiority clinical trial. METHODS Patients who underwent anterior and posterior segments combined surgery or glaucoma surgery or complex posterior segment surgery were eligible to participate. Patients were administered a single subconjunctival injection of 250 μL XG-102 90 μg (n = 47) or 900 μg (n = 48) or placebo (n = 50) at the end of ocular surgery. Subconjunctival injection for each group (XG-102 90 μg, XG-102 900 μg, or placebo) was followed by eye drops instilled 4 times per day for 21 days with placebo, placebo, or dexamethasone solution, respectively. The primary outcome measure was anterior chamber cell grades at day 28 comparing XG-102 900 μg with dexamethasone. RESULTS The anterior cell grades for both XG-102 groups were noninferior to dexamethasone (-0.054 anterior cell grade [95% confidence interval -0.350-0.242]; P < .001 for noninferiority) for XG-102 900 μg and -0.086 anterior cell grade (95% confidence interval -0.214-0.385; P = .003 for noninferiority) for XG-102 90 μg. Rescue medication was introduced for 10 (21%), 7 (15%), and 2 (4%) patients allocated to the XG-102 90 μg, XG-102 900 μg, and dexamethasone groups, respectively. The difference between XG-102 90 μg and dexamethasone was statistically significant (P = .013). The number of patients for whom adverse events were reported and the nature of the events reported was similar between the 3 treatment groups. CONCLUSIONS A single subconjunctival injection of XG-102 at the end of ocular surgery is noninferior to dexamethasone eye drops in the treatment of postoperative ocular inflammation.

Abstract
AIMS To evaluate the outcomes of epiretinal membrane (ERM) surgery in highly myopic eyes and to compare them with those from non-highly myopic eyes. METHODS Retrospective nested case-control study from a cohort of 1776 consecutive patients (1776 eyes) who underwent surgery for ERM. Fifty-seven highly myopic eyes (with axial length longer than 26 mm) were included in the study group and were matched for preoperative visual acuity and duration of symptoms with 57 non-highly myopic control eyes selected from the same cohort. The best-corrected visual acuity (BCVA), the relationship between axial length and visual improvement, the central macular thickness (CMT) and the surgical complications were analysed. RESULTS The mean axial length was 27.3±1.1 mm in highly myopic eyes and 23.1±1 mm in controls (p<0.001). At the 1-year final examination, the mean BCVA significantly improved from 0.62±0.23 logarithm of minimal angle of resolution (logMAR) to 0.27±0.21 logMAR in the study group (p<0.001) and from 0.61±0.22 logMAR to 0.25±0.15 logMAR in the control group (p<0.001). Similarly, the mean CMT significantly decreased in both groups (p<0.001). The two groups did not differ statistically in terms of visual and anatomical changes as well as surgical complications. There was no significant correlation between axial length and visual recovery. CONCLUSIONS ERM surgery resulted in similar anatomical and functional outcomes in both groups. Longer axial length does not seem to affect visual improvement and the complication rate.

Abstract
PURPOSE To evaluate the outcomes of macular hole (MH) surgery with 3-day prone positioning in highly myopic eyes and to compare them with those from non-highly myopic eyes. DESIGN Retrospective nested case-control study from a cohort of 496 consecutive patients (496 eyes) who underwent surgery for MH. PARTICIPANTS Forty-seven highly myopic eyes (with axial length >26 mm) were included in the study group and were matched for MH size and duration of symptoms with 47 non-highly myopic control eyes selected from the same cohort. METHODS All patients underwent pars plana vitrectomy, internal limiting membrane peeling, and 17% hexafluoroethane gas filling. Patients then were advised to maintain strict face-down positioning for 3 days only and to avoid the supine position during the night for a minimum of 1 week. MAIN OUTCOME MEASURES The MH closure rate, the relationship between axial length and closure rate, the best-corrected visual acuity (BCVA), and the surgical complications were analyzed. RESULTS The mean axial length was 28.5±2.2 mm in highly myopic eyes and 23.3±1.1 mm in controls (P < 0.001). Closure of the MH was achieved in 39 of 47 eyes (83%) in the study group and in 45 of 47 eyes (95.7%) in the control group (P = 0.045). Anatomic outcomes tended to decrease when axial length increased (P = 0.066). Mean BCVA improved in both groups (0.41±0.39 logarithm of the minimal angle of resolution [logMAR] vs. 0.68±0.34 logMAR) but was significantly lower in highly myopic eyes (P < 0.001). Retinal detachment occurred in 8.5% of highly myopic patients versus 2.1% of controls, but the difference was not significant. CONCLUSIONS Macular hole surgery with 3-day postoperative positioning in highly myopic eyes resulted in satisfactory anatomic and functional outcomes. However, the MH closure rate and mean improvement of visual acuity were less favorable than those in control eyes. Longer axial length may increase the risk of anatomic failure.

Abstract
A 34-year-old man was examined 4 hours after blunt ocular trauma with a stone. Visual acuity was hand motions in the right eye and 10/10 in the left eye. Slit-lamp examination after resorption of a hyphema revealed 180◦ superior iridodialysis and a total white intumescent cataract precluding visualization of the posterior capsule. Phacoemulsification was undertaken after repositioning the iris with microretractors. Intraoperatively, we discovered that the cen-tral portion of the posterior capsule presented a 4-mm oval opening with thick and fibrosed edges. The posterior chamber lens was safely implanted in the bag with no enlargement of the posterior capsule rupture. Postoperatively, VA improved only to 1/20 and fundus OCT revealed the presence of a 400-micron, oval-shaped macular hole that was successfully closed with sub-sequent vitrectomy and gas tamponade. Visual acuity stabilized at 5/10, D3, and the lens was stable without decentration after 36 months follow-up.

Abstract
Age-related macular degeneration (ARMD) is a multifactorial disease caused by a combination of genetic and environmental factors. It is the first cause of blindness in patients over 50 in the western world. The disease has been traditionally classified into early and late stages with dry (atrophic) and wet (neovascular) forms: neovascular form is characterized by new blood vessels development under the macula (choroidal neovascularisation) which lead to a rapid decline of vision associated with metamorphopsia and requiring an urgent ophtalmological examination. Optical coherence tomography is now one of the most important part of the examination for diagnosis and treatment. Patient with age related maculopathy should consider taking a dietary supplement such that used in AREDS. The treatment of the wet ARMD has largely beneficied since year 2006 of anti-VEGF (vascular endothelial growth factor) molecules such as ranibizumab or bevacizumab given as repeated intravitreal injections. A systematic follow up each 4 to 8 week in required for several years. There is no effective treatment at the moment for dry AMD. For patients with binocular visual acuity under 60/200 rehabilitation includes low vision specialist, vision aids and psychological support.

Abstract
A newborn who had familial high myopia presented with bilateral dense vitreous hemorrhage after forceps delivery. Vitrectomy in the right eye revealed a macular hole surrounded by pigmented cells. After subsequent surgery, the macular hole healed and remained closed during 10 years of follow-up, but profound amblyopia persisted. Macular hole is a possible complication of forceps delivery. Vitrectomy associated with inner limiting membrane peeling and gas tamponade was effective in closing macular hole in a newborn but was unable to prevent amblyopia.

Abstract
OBJECTIVE To establish whether the success rate of surgery for small idiopathic macular holes (diameter, ≤ 400 μm) is significantly reduced if facedown positioning is replaced by simply taking care to avoid the supine position. DESIGN Randomized, controlled, parallel-assignment, open-label, interventional, multicenter clinical trial. PARTICIPANTS Sixty-nine patients from 6 specialized vitreoretinal units, randomized into 2 parallel groups and followed up after surgery for 3 months. METHODS All patients underwent pars plana vitrectomy, peeling of any epiretinal membrane, and 17% C₂F₆ gas filling. Patients then were advised randomly to observe either strict facedown positioning for 22 of 24 hours or simply to avoid the supine position for 10 days. MAIN OUTCOME MEASURES The primary outcome measure was the rate of anatomic closure 3 months after surgery. Main secondary measurements included Early Treatment Diabetic Retinopathy Study (ETDRS) visual acuity, progression of cataract, and frequency of complications. RESULTS The mean size of macular holes was approximately 300 μm in both groups. Closure rates were more than 90% in both groups: 32 (91.4%) of 34 eyes in the alleviated positioning group versus 32 (94.1%) of 35 eyes in the facedown positioning group (lower margin of 95% confidence interval of difference, -14.88%). The ETDRS scores at 3 months increased in both groups by 10.23 ± 14.64 and 10.52 ± 14.54 letters, respectively. Progression of cataract and the rate of other complications were not significantly different in the 2 groups. CONCLUSIONS The success rate of surgery for idiopathic macular holes of 400 μm or smaller is not significantly reduced if facedown positioning is replaced by simply taking care to avoid the supine position. These macular holes can be treated by streamlined surgery, that is, with no internal limiting membrane peeling and no facedown positioning (only avoidance of the supine position) with a closure rate of more than 90% and a mean gain in visual acuity of more than 2 ETDRS lines at 3 months.

Abstract
BACKGROUND To assess the functional and anatomical outcome of primary vitrectomy without scleral buckling for rhegmatogenous retinal detachment (RRD) in pseudophakic patients and to present the learning curve for this surgery in less experienced surgeons. METHODS We reviewed the charts of pseudophakic patients treated with primary vitrectomy without scleral buckling for a rhegmatogenous retinal detachment with PVR<C in two academic centres by four surgeons (two more experienced and two less experienced surgeons) for 1 year. The primary endpoint was the reattachment rate with a single procedure by less experienced and more experienced surgeons. Then, to assess the learning curve of this treatment, we compared the results obtained in consecutive pseudophakic patients by less experienced surgeons at the beginning and after a 2-year training period. RESULTS First, 133 patient charts with a minimum follow-up of 6 months were included. Retinal reattachment was achieved with a single surgery in 75.2% for all surgeons. This rate was 80.9% for more experienced surgeons compared to 70% for less experienced surgeons (p = 0.37). In another series of 239 patients operated on by less experienced surgeons, the success rate obtained at the beginning of the training period for less experienced surgeons significantly increased after 2 years (from 66.7% to 80%, p < 0.049). CONCLUSION Primary vitrectomy without scleral buckling is an effective procedure to treat pseudophakic retinal detachment. Less experienced surgeons need sufficient time to achieve acceptable success rates, reflecting the learning curve for this procedure.

Abstract
PURPOSE The aim of our study was to assess and to characterize the ocular involvement in patients with primary central nervous system lymphoma. POPULATION AND METHODS We conducted a prospective study between August 1995 and December 1998 on a cohort of consecutive patients affected by primary central nervous system lymphoma and who underwent a systematic ophthalmological examination before treatment. RESULTS The study population comprised 24 patients (mean age, 57 years; 16 women and 8 men). Among these patients, 6 had ocular involvement (2 patients with ocular signs revealing the cerebral process, 2 evidenced at the time of the initial ocular examination, and 1 as the disease evolved). Ocular involvement was vitritis in all cases, anterior uveitis in 1 patient, obliterant vasculitis in 1 patient and yellowish subretinal lesions in 1 patient. In 1 case, a vitrectomy led to adequate diagnosis of the disease. CONCLUSION Our study shows a 25% incidence of ocular involvement in patients with primary central nervous system lymphoma, with posterior uveitis as the most common manifestation. Because of the relatively high incidence of ocular involvement, a systematic ophthalmological examination of this subset of patients should be mandatory.

Abstract
OBJECTIVE Some complications of vitrectomy are related to adherence of the vitreous body to the retina. We studied whether these complications could be decreased by injecting a proteolytic enzyme, tissue plasminogen activator (TPA), at the beginning of surgery to aid separation of the vitreous from the retina. METHODS Fifty-six patients receiving surgery for complications of proliferative diabetic retinopathy were divided into two groups in this prospective, randomized, double-blind study. Group I patients received 25 microg of intravitreal TPA in buffered salt solution (BSS) 15 minutes before vitrectomy. Group II received BSS alone. Postoperative follow-up lasted up to 3 months. The major criteria for comparison were the number of perioperative iatrogenic tears, the gain in visual acuity, and the reattachment rate of tractional retinal detachments. RESULTS No difference was found between the two groups for the principal indicators or for complications. CONCLUSION In proliferative diabetic retinopathy, the use of 25 microg of TPA by intravitreal injection 15 minutes before vitrectomy does not improve the results. No specific complications of the method were noted. The failure can be attributed to a too-short delay between TPA injection and beginning of surgery, an insufficient dose, or an insufficient quantity of plasminogen in the vitreous at the beginning of the intervention.

Abstract
PURPOSE To study the effect of preceding tenectomy of the medial rectus tendon on the results of medial rectus muscle recession. SUBJECTS AND METHODS Eighteen consecutive cases of incomitant esotropia were retrospectively reviewed. The average preoperative esotropia was 35 PD with an incomitant deviation between 10 PD and 30 PD. All patients underwent 7 mm bilateral medial rectus muscle recession after 4 mm tenectomy of the anterior medial rectus muscle. RESULTS Fourteen patients (78%) had "satisfactory" results (within 10 PD static esodeviation and 12 PD dynamic deviation [incomitance]). Four (22%) were undercorrected. One showed a postoperative consecutive exotropia of 4 PD at distance only. CONCLUSIONS Tenectomy of the anterior muscle tendon preceding large recessions of the medial rectus was effective in reducing the frequency of overcorrection (consecutive exotropia). Undercorrection did not appear to be more common.

Abstract
A 22-year-old-lady presented with multiple occlusions of the branches of the central retinal artery, accompanied by neuro-encephalic disorders and deafness. This triad is known as SICRET Syndrome (Small Infarction of Cochlear, Retinal and Encephalic Tissue). This rare syndrome, as well referred to as Susac syndrome, affects only the women and the three tissues mentioned above: eye, ear, brain. The course was characterised by a series of partially regressive evolutive steps. A remission had been obtained since two years with immuno-supressor and anti-coagulant therapy. The neuro-encephalic and cochlear disorder regressed in contrast to the severe sequel on the right eye.

Abstract
BACKGROUND A study of the characteristics and the results obtained in 99 consecutive eyes operated on for rhegmatogenous retinal detachment associated with aphakia or pseudophakia in order to find the predictive factors of poor anatomical and functional results. METHODS The authors retrospectively reviewed the files of 99 consecutive cases of aphakic and pseudophakic retinal detachment operated on by the same surgeon between January 1992 through July 1993 with a minimum follow-up of 6 months. Multivariate and chi square analysis were carried out. RESULTS Of the pseudophakic eyes, 25 had an anterior chamber lens and 48 had a posterior chamber lens. The posterior capsule was disrupted using a Yag laser in 58% of those with an posterior chamber lens but only 14% of them developed detachment within 6 months. The rate of vitreous loss was 27% with 5% in case of intracapsular extraction, 31% in case of extracapsular extraction and 54% in case of phacoemulsification. PVR was present in 30% of the patients and 51% of detachments occurred more than 24 months as a mean after cataract surgery. The overall anatomic reattachment rate was 88% with no significant difference between the aphakic and the pseudophakic patients, either with an anterior chamber of posterior chamber lens. Visual results were significantly worse in the anterior chamber lens group and in the aphakic eyes (P < 0.02). Negative prognostic indicators for reattachment included poor preoperative vision, extension of the retinal detachment to the macula (P < 0.05) and grades B, C or D proliferative vitreoretinopathy (P < 0.01). In addition to the above factors, eyes with vitreous loss, anterior chamber lens, aphakia and a larger extent of the retinal detachment had a poor visual outcome. CONCLUSION Most aphakic or pseudophakic retinal detachment can now be reattached with either scleral or vitreo retinal surgery. The main difficulties are the localisation of the breaks and the treatment of PVR. Indirect ophthalmoscopy associated with vitrectomy does well in cases of an opacified posterior capsule. In cases of severe PVR long term internal tamponade either with C3F8 or silicone oil improves anatomical results but the functional results remain inferior.

Abstract
This study evaluates the efficiency of fluid-air exchange on the reattachment of the retina and clarifies the possibility that a posterior retinotomy is a cause for intra- and postoperative complications. A consecutive series of 211 eyes with retinal detachments due to P.V.R. (47%), diabetic traction, perforating trauma, macular hole or giant tears is presented. All eyes underwent pars plana vitrectomy, fluid-air exchange, internal drainage of subretinal fluid, laser endophotocoagulation and scleral buckling of the tears; 56% of the eyes were phakic and 55% underwent a posterior retinotomy, 54% underwent tamponade with C3F8 and 46% with silicone oil. Intraoperatively the retina was completely flattened in 91% cases. The causes of incomplete reattachment were residual membranes (6.6%), poor visualization (1.4%) and suprachoroidal hemorrhage (1%). These complications were isolated as being the cause of the bad final results (p < 0.001). Postoperatively, the retina remained attached in 66% of cases after the first procedure and with further surgery in 81% (mean follow up 16 months). Best corrected visual acuity was improved in 73% of eyes, unchanged in 17%, and worse in 10%. Complications were retraction of the retinotomy site in 3 cases and peripheral choroidal hemorrhage in 4 cases. We concluded that fluid air exchange with internal subretinal fluid drainage was an efficient and safe technique even if a posterior retinotomy was necessary.

Abstract
ALO 2145 (Apraclonidine Chlorhydrate)*, is a new hypotensive agent; it acts as a selective alpha-2-adrenergic agonist to produce a marked reduction in intraocular pressure with minimal effect on the cardiovascular system. 38 patients undergoing ocular laser surgery were allocated to treatment with either ALO 2145 1% (n = 20), or to placebo (n = 18), in a double-masked fashion. One drop of study medication was instilled into the operative eye one hour before laser surgery, and one drop immediately after the laser surgery. ALO 2145 treated eyes exhibited a significantly lower mean intraocular pressure increase in the immediate postoperative phase, compared with placebo treated eyes. ALO 2145 also significantly reduced the postoperative incidence of intraocular pressure spikes, defined as intraocular pressure increases of more than 10 mmHg over baseline (17% of cases for active treatment vs 60% of cases for placebo). ALO 2145 1% was shown to be effective and well tolerated in the dosage regimen employed in this study.

Abstract
The authors study an observation of unusual localisation, near the optic disc, of periphlebitis associated to multilocular sclerosis. There are some cicatricial periphlebitis and active others, which are more peripheral, alone without any uveitis. These ones resolved in two months with cortisone treatment.

Abstract
56 patients with primary retinal detachment were treated by pneumatic retinopexy. The overall success rate for reattachment with one operation was 66%. Postoperative complications included development of new tears (18%) and P.V.R. (16%). Pneumatic retinopexy is a valuable new technique, however careful patient selection and postoperative management is required.

Abstract
90 diopters lens is very performing for indirect ophthalmoscopy in pseudophakic patients, for macular fine examination and to realise difficult laser photocoagulation (through gas or silicon). 90 D lens is also safer since it never touches the eye.

Abstract
Intraocular silicone oil tamponade is used as an adjunct to vitrectomy in the treatment of proliferative vitreoretinopathy. The authors analyzed the effect of silicone oil on the corneal endothelium in 28 patients (10 phakic and 18 aphakic). In the phakic group, the endothelial cellular loss is small, no significant. In the aphakic group, the endothelial cellular loss is 20%.

Abstract
Controlled vacuumed drainage of subretinal fluid is achieved using a 25 gauges butterfly needle and a syringe. This technique often totally flattens the retina during the operation. It seems particularly indicated in inferior retinal detachment without break.

Abstract
The authors present 17 cases of perforating ocular injuries caused by fire arms. They successively describe circumstances of trauma, initial injuries, surgical techniques employed and their results. The mean follow-up of patients is about one year. They particularly insist on severity of this type of trauma and legislative problems caused by free sale of some of these arms, more specially so called self defence pellets guns.

Abstract
Uveal effusion syndrome is a rare entity. It associates a nonrhegmatogenous retinal detachment, an annular cilio-choroïdal detachment and peripheral vascular anomalies. It is important to differentiate it from the another retinal detachments and the malignant melanoma.

Abstract
Aetiologic conditions for enlargement of extra ocular muscles are graves' orbitopathy, acute or subacute myositis as a subgroup of inflammatory orbital pseudotumor, and sometimes lymphoid or metastatic tumor. The distinction of these aetiologies can be made on clinical versus CT Scan or IRM grounds with two different patterns of oculomotor disfunction. Restrictive extensibility, which found expression in the antagonist field, is typical of grave's myopathy, sequelae of subacute myositis or acute myositis of the superior oblique. Deficiency of the enlarged muscle's contractibility is typical of a recent and transient myositis involving a rectus muscle or of a rare tumor of an extraocular muscle.
