RESUMO

PURPOSE: This study aims to investigate the postoperative refractive outcomes in eyes that underwent the flanged intrascleral intraocular lens (IOL) fixation combined with vitrectomy with or without gas/air tamponade. METHODS: The eyes were divided into two groups (Group A; eyes that underwent flanged intrascleral IOL fixation with gas/air tamponade, and Group B; eyes that underwent flanged intrascleral IOL fixation without gas/air tamponade). The predicted spherical equivalent (SE) refraction values were calculated using the Sander-Retzlaff-Kraff Theoretical formula. Then, the prediction error was calculated by subtracting the predicted SE refraction from the postoperative objective SE refraction and the absolute prediction error was calculated as the absolute value of the prediction error for each eye. RESULTS: A total of 68 eyes were included in the current study. There was a significant correlation between the predicted and postoperative SE refraction in both groups (Group A, r = 0.968, P < 0.0001, Group B, r = 0.943, P < 0.0001, linear regression analysis). The prediction error demonstrated a mild myopic shift after the flanged intrascleral IOL fixation in both groups (Group A, -0.40 ± 0.96 diopter, Group B, -0.59 ± 0.95 diopter). There was no significant difference in prediction error and absolute prediction error between the two groups ( P = 0.44, P = 0.70, Wilcoxon rank sum test). CONCLUSION: The postoperative SE refraction after flanged intrascleral IOL fixation was not influenced by gas/air tamponade.

RESUMO

PURPOSE: Haptic repositioning during flanged intraocular lens (IOL) fixation can be difficult, and the haptic requiring repositioning may be at increased risk of excessive bending or breakage. This study aimed to report double-needle haptic repositioning technique outcomes for the aforementioned difficulty during flanged IOL fixation. METHODS: This retrospective case series included seven eyes requiring haptic repositioning during flanged IOL fixation. The method features reinsertion of an already externalized haptic into the needle lumen followed by a needle-haptic complex internalized through the original tract into the eyeball. Thus, an adequate configuration for contralateral haptic can be achieved for insertion into the needle lumen to create a double-needle condition before both haptics are successfully externalized. RESULTS: The median follow-up duration was 24 months (range, 4-24 months). Postoperatively, the IOL was well-centered, and corrected distance visual acuity improved from 20/320 (20/4,000-20/70) to 20/50 (20/250-20/20). No intraoperative or postoperative complications were noted. CONCLUSION: The technique produced encouraging results in patients undergoing haptic repositioning during flanged IOL fixation. This technique could potentially reduce haptic overbending risk and facilitate haptic adjustment. Further studies are needed to confirm the feasibility of the technique.

RESUMO

PURPOSE OF REVIEW: To review variations of flanged intraocular lens fixation (Yamane technique) and their outcomes. RECENT FINDINGS: Sutureless intrascleral IOL fixation has become popular, and many techniques have been reported. Among them, the Yamane technique has been widely used in recent years, and there are many variations. However, there are no reports that systematically compare them. SUMMARY: There are variations of the Yamane technique, such as those used to create a scleral tunnel or to dock needles and haptics. Although few reports have directly compared each technique, small scleral wounds appear to be beneficial for long-term stability of the IOL. A method of fixing a capsule tension segment or iris using a flange has also been reported, demonstrating the diverse range of uses of the flange.

RESUMO

PURPOSE: Early detection and treatment are important management strategies for neovascular age-related macular degeneration (AMD). The purpose of this study was to determine the sensitivity and specificity in detecting neovascular AMD using two wide-field imaging systems: ClarusTM (CLARUS 500™, Carl Zeiss Meditec AG, Jena, Germany) and Optos®(Optos California®, Optos PLC, Dunfermline, United Kingdom), compared to conventional digital fundus photographs. METHODS: We retrospectively analyzed 109 eyes of 73 consecutive patients with neovascular AMD, who underwent standard examination and multimodal imaging, including fundus photography, and optical coherence tomography (OCT). Unmasked graders utilized slit-lamp biomicroscopy and OCT to diagnose neovascular AMD. Masked graders evaluated ClarusTM, Optos®, and digital fundus photograph methods to determine the presence of choroidal neovascularization associated with AMD. Sensitivity and specificity analyses were performed using combined fundoscopy and OCT as the reference standard. RESULTS: Ninety eyes were diagnosed with neovascular AMD and the remaining 19 eyes were normal based on the reference standard. Of these, neovascular AMD was detected using ClarusTM in 94.4% (85/90). The sensitivities of Optos® and digital fundus photographs were 81.1% (73/90) and 87.8% (79/90), respectively. The specificities using ClarusTM, Optos®, and digital fundus photographs were 89.5% (17/19), 94.7% (18/19), and 89.5% (17/19), respectively. CONCLUSION: ClarusTM, with its ability to image high-resolution wide field fundus, was considered superior for diagnosing neovascular AMD with high sensitivity and specificity. It may be a useful screening tool for early detection of neovascular AMD, facilitating prompt referral and treatment.

RESUMO

PURPOSE: To compare the 1-year visual outcomes and anatomical responses of patients who received photodynamic therapy (PDT) combined with intravitreal ranibizumab (IVR) injections with those of patients who received PDT combined with intravitreal aflibercept (IVA) injections for treating polypoidal choroidal vasculopathy (PCV). METHODS: We retrospectively studied all treatment-naïve patients with PCV who received PDT combined with either IVR or IVA. Best-corrected visual acuity (BCVA), central macular thickness (CMT), central choroidal thickness (CCT), the number of additional injections, and the presence of polypoidal lesions, as indicated by indocyanine green angiography (ICGA), during 1 year were evaluated. RESULTS: Forty-four eyes were assessed at the 1-year follow-up examination. Of these, 23 were treated with PDT combined with IVR (PDT/IVR group), and 21 were treated with PDT combined with IVA (PDT/IVA group). In both groups, BCVA was shown to be significantly improved 1 year after the initial treatment. CMT and CCT were also significantly decreased after 1 year. There were no significant differences in the changes in BCVA or CMT between the two groups. However, the change in CCT in the PDT/IVA group was significantly larger than that of the PDT/IVR group (P < 0.001). The mean number of additional injections was 0.78 ± 0.21 in the PDT/IVR group and 0.57 ± 0.21 in the PDT/IVA group with no significant difference between the two groups (P = 0.45). The polyp regression rate at 12 months was 78.2% in the PDT/IVR group and 78.9% in the PDT/IVA group with no significant difference between the two groups. CONCLUSIONS: PDT combined with either IVR or IVA was well tolerated and appeared to improve both vision and anatomy in patients with PCV. PDT/IVA may have a more pronounced effect on macular choroidal thickness at 1-year follow-up.

RESUMO

PURPOSE: To compare surgical outcomes between the inverted internal limiting membrane (ILM) flap technique and ILM peeling for macular hole retinal detachment (MHRD) in eyes with high myopia. DESIGN: Multicenter cohort study. PARTICIPANTS: We retrospectively reviewed medical records of consecutive patients treated between June 2008 and September 2018 at 7 hospitals and included 100 eyes with MHRD associated with high myopia in our study. All eyes underwent vitrectomy with the inverted ILM flap technique (57 eyes) or ILM peeling (43 eyes) and were followed up for more than 6 months. METHODS: We estimated odds ratios and their 95% confidence intervals (CIs) for macular hole (MH) closure using multivariate logistic regression analysis. We also examined factors associated with the postoperative best-corrected visual acuity (BCVA) at the final visit using multiple linear regression analysis. MAIN OUTCOME MEASURES: Macular hole closure and postoperative BCVA at the final visit. RESULTS: The MH closure rate was significantly higher in the inverted ILM flap group (80.7%) than in the ILM peeling group (37.2%; P < 0.001). Moreover, postoperative BCVA at the final visit was significantly better in the former group (0.88 ± 0.48 vs. 0.99 ± 0.48; P = 0.03). The retinal attachment rate (ILM flap, 91.2%; ILM peeling, 79.5%; P = 0.229) and recovery rates for the external limiting membrane and ellipsoid zone line (ILM flap, 10.9%; ILM peeling, 0%; P = 0.12) showed no significant intergroup differences. After adjustment for age, axis, tamponade substance, and dye for ILM staining, the inverted ILM flap technique was associated strongly and positively with MH closure (odds ratio, 7.14; 95% CI, 2.72-18.7; P = 0.001). Moreover, the inverted ILM flap technique and preoperative BCVA were associated significantly and positively with the postoperative BCVA at the final visit. CONCLUSIONS: Our findings suggest that the MH closure rate and postoperative visual outcome for eyes with high myopia-associated MHRD are better with the inverted ILM flap technique than with ILM peeling. Thus, vitrectomy with the inverted ILM flap technique should be considered as the initial surgery for MHRD associated with high myopia.

RESUMO

PURPOSE: To identify the functional outcome and evaluate the morphologic changes of patients with pachychoroid neovasculopathy (PNV) undergoing intravitreal anti-vascular endothelial growth factor (VEGF) combined with photodynamic therapy (PDT) at the 1-year follow-up. METHODS: We retrospectively studied all the treatment-naïve PNV patients who were scheduled to undergo combination therapy between September 2017 and November 2018. All the patients received three consecutive monthly injections of 0.5 mg/0.05 mL ranibizumab as loading doses. Full-dose PDT was performed within 1 week of the first injection. Retreatment was allowed if evidence of clinical deterioration or the presence of fluid on spectral-domain optical coherence tomography examination performed at the 1-month follow-up was noted. The best-corrected visual acuity (BCVA) was compared before treatment and at 3, 6, and 12 months after the initial treatment. Changes in the central foveal thickness (CFT), central choroidal thickness (CCT), and retreatment rate during the maintenance phase were also evaluated. RESULTS: Eleven eyes were enrolled in this study. Significantly, better BCVA was observed at 12 months than at baseline (P = 0.010). The mean CFT significantly decreased from 331 ± 93 to 237 ± 72 µm at 12 months (P < 0.001). The mean CCT also significantly decreased from 361 ± 74 to 310 ± 83 µm at 12 months (P < 0.001). The mean number of injections per eye was 3.9 ± 1.3 during the follow-up period. A total of 45.5% (5 /11) of the patients required retreatment during the maintenance phase. CONCLUSION: Anti-VEGF combined with full-dose PDT was well tolerated and appeared to be effective treatment for patients with treatment-naïve PNV. Combination therapy might also reduce the treatment burden with fewer injections in patients with PNV.

RESUMO

The surgeons have modified the flanged intrascleral intraocular lens (IOL) fixation technique initially described by Yamane et al. to avoid manipulation of the IOL within the anterior chamber. Their technique involves securing the IOL haptics into receiving needles within the posterior segment. Advantages of this technique include repositioning and securing a dislocated three-piece IOL to the sclera without removing the lens or creating a large corneal incision.

RESUMO

PURPOSE: To report the results of 9-year follow-up examinations and predictive factors for visual acuity outcome after intravitreal injection of anti-vascular endothelial growth factor (VEGF) agents to treat retinal angiomatous proliferation (RAP). METHODS: We conducted a retrospective observational study of 85 treatment-naïve eyes in 61 patients (21 men, 40 women; age range, 70-95 years; mean age, 84.0 years) treated with intravitreal injections of anti-VEGF agents. All patients received three consecutive monthly injections as an induction treatment. During the maintenance phase, the patients received intravitreal injections as needed or fixed dosing. The primary outcome measures were best-corrected visual acuity (BCVA) during the follow-up period. Furthermore, we investigated potential predictive factors of improvement in visual acuity. The proportion of patients who developed specific complications were also analyzed. RESULTS: The mean BCVA gradually decreased from 0.58 at baseline to 0.70 at 36 months (P = 0.146), 0.82 at 48 months (P = 0.004), and 0.92 at 108 months (P = 0.021). Improvement in visual acuity at the final visits was associated with baseline visual acuity and central foveal thickness. Massive subretinal hemorrhage, fibrotic scars, and macular atrophy developed in 4 (4.7%), 9 (10.6%), and 50 (56.8%) eyes, respectively, at the final visits, and were all significantly associated with final visual acuity (P = 0.013, P < 0.001, and P = 0.001, respectively). CONCLUSION: Long-term stabilization of vision in patients with RAP, regardless of treatment modality, was difficult to achieve by using intravitreal injections of anti-VEGF agents. Earlier detection and treatment are important to maintain visual acuity in patients with RAP.

RESUMO

Oxidative stress and inflammation play a critical role in the initiation and progression of age-related ocular abnormalities as cataract, glaucoma, diabetic retinopathy, and macular degeneration. Therefore, phytochemicals with proven antioxidant and anti-inflammatory activities, such as carotenoids and polyphenols, could be of benefit in these diseases. We searched PubMed and Web of Science databases for original studies investigating the benefits of different carotenoids and polyphenols in age-related ophthalmic diseases. Our results showed that several polyphenols (such as anthocyanins, Ginkgo biloba, quercetin, and resveratrol) and carotenoids (such as lutein, zeaxanthin, and mezoxanthin) have shown significant preventive and therapeutic benefits against the aforementioned conditions. The involved mechanisms in these findings include mitigating the production of reactive oxygen species, inhibiting the tumor necrosis factor-α and vascular endothelial growth factor pathways, suppressing p53-dependent apoptosis, and suppressing the production of inflammatory markers, such as interleukin- (IL-) 8, IL-6, IL-1a, and endothelial leucocyte adhesion molecule-1. Consumption of products containing these phytochemicals may be protective against these diseases; however, adequate human data are lacking. This review discusses the role and mechanisms of polyphenols and carotenoids and their possible synergistic effects on the prevention and treatment of age-related eye diseases that are induced or augmented by oxidative stress and inflammation.

RESUMO

OBJECTIVES: To examine the causes of congenital nasolacrimal duct obstruction (CNLDO) using dacryoendoscopy, and to evaluate the surgical outcomes of primary transcanalicular endoscopic dacryoplasty. METHODS: The subjects of this study were a total of 56 eyes of 46 Japanese children aged one to five years old (mean, 29.1 ± 14.0 months old) with clinically diagnosed CNLDO. The blockage was visualized and probed using a dacryoendoscope (MD10 with a 20 G probe, Fiber Tech Co., Ltd., Japan) under general anesthesia. We used a self-retaining bicanalicular lacrimal stent (Lacrifast®, Kaneka Co., Ltd., Japan) for nasolacrimal duct intubation. RESULTS: In each case the obstruction was found to be caused by a single focal blockage at the distal end of the duct. A nasolacrimal dacryolith was observed in 5 eyes (9%) and successfully removed using the dacryoendoscope. The success rate of probing by subsequent nasolacrimal duct intubation was 100%. No complications were observed. CONCLUSIONS: We obtained a 100% success rate with primary transcanalicular endoscopic dacryoplasty for the treatment of CNLDO. Direct visualization inside the lacrimal passage allowed for precise probing, even in infants, leading to successful treatment of CNLDO without any complications.

RESUMO

OBJECTIVE: The study aimed to perform a systematic review and meta-analysis of randomized controlled trials comparing the efficacy and complications of autologous blood versus using fibrin glue and surgical sutures for conjunctival autograft fixation in primary pterygium surgery. DESIGN: Systematic review with quantitative meta-analysis. METHODS: Four authentic databases have been searched using relevant keywords. Eligible studies were obtained, and their data were extracted into an online form. Analysis was done using Review Manager for windows. Dichotomous outcomes were reported as risk ratio, while continuous data were reported as mean difference. RESULTS: Seven studies were included in the analysis. Most of the included studies were of moderate quality according to Cochrane Risk of Bias assessment tool. There was no difference between the three techniques in recurrence rates (Risk Ratio (RR) 0.80, 95% CI [0.45 to 1.44], p= 0.46). Graft retraction and displacement were more profound in the autologous blood group vs fibrin glue and suture groups (RR 3.22, 95% CI [1.48 to7.02], p= 0.003) and (RR 5.27, 95% CI [2.24 to 12.38], p> 0.001) respectively. In terms of operative time, fibrin glue took shorter while suturing took longer time compared to blood coagulum (Mean Difference (MD) =1.57, 95% CI [0.90, 2.25], p> 0.00001) and (MD -20.47, 95% CI [-38.05 to -2.88], p =0.02). CONCLUSION: Autologous blood for conjunctival autograft fixation in primary pterygium surgery was associated with lower graft stability than fibrin glue or sutures. However, it did not account for higher recurrence rates than the fibrin glue or sutures. Patient satisfaction and postoperative symptoms are relatively better in the blood coagulum group than the other techniques. The overall quality of evidence is low. Further well designed randomized controlled trials are still needed.

RESUMO

PURPOSE: To evaluate the prognosis and response of neovascular age-related macular degeneration (AMD) to anti-vascular endothelial growth factor (VEGF), according to the components of subretinal hyperreflective material (SHRM) classified using optical coherence tomography angiography (OCTA), is the aim of this study. METHODS: We retrospectively studied 39 eyes of 39 consecutive patients with SHRM associated with exudative AMD, who underwent standard examination and multimodal imaging, including fundus photography, optical coherence tomography (OCT), and OCTA. We classified SHRM into type 2 neovascularization (NV), fibrosis, subretinal hyperreflective exudation (SHE), and hemorrhage using OCTA. If compound SHRM was found, components in the foveal center were considered. All patients except one with fibrosis received anti-VEGF treatment for more than 12 months. The best-corrected visual acuity (BCVA) values measured before treatment and at 3, 6, and 12 months after the first injection were compared according to the components of SHRM. RESULTS: Using OCTA, 11 eyes with type 2 NV showed abnormal blood flow and 1 eye with fibrosis showed strong surface projection. Both SHE and hemorrhage components showed projection artifact with no intrinsic flow. However, OCTA enabled eyes with SHE (17 eyes) to be distinguished from those with hemorrhage (10 eyes) because hemorrhage showed masking of choriocapillaris flow. Eyes with SHE showed a significant improvement in the mean logMAR BCVA as compared with the value at the baseline, which was sustained throughout the 12-month follow-up period (p < 0.05). In eyes with type 2 NV and hemorrhage, no significant difference in the mean BCVA values was observed at any follow-up time-point (all, p > 0.05). CONCLUSION: OCTA was useful to noninvasively distinguish SHRM components. It may be important to consider the components of SHRM to predict the visual acuity in patients with AMD.

RESUMO

Central retinal artery occlusion (CRAO) is a severe disease, often causing blindness. We evaluated the efficacy and safety of a surgical procedure for the treatment of acute CRAO in which retinal arterial cannulation with tissue plasminogen activator (tPA) is performed. The surgical procedure consisted of vitrectomy followed by cannulation of the central retinal artery and injection of tPA (200 µg) using a 47-gauge microneedle. Thirteen CRAO patients were treated within 48 hours of the onset of symptoms. The central retinal artery of all 13 eyes was successfully cannulated. The mean interval between the onset of symptoms and surgery was 38.7 hours. The results for all 13 eyes treated showed a statistically significant improvement in mean visual acuity between before and one month after treatment (-1.60 vs. -0.82 logarithmic values for minimum angle resolution (LogMAR), p = 0.0021). Fluorescein angiography showed complete reperfusion and incomplete reperfusion in 10 eyes and 3 eyes, respectively. Recently developed surgical instruments have made retinal-arterial cannulation feasible. Intra-retinal-arterial cannulation has potential as a method of improving visual function and microcirculation in eyes affected by CRAO.

RESUMO

PURPOSE: To compare the 3-year follow-up results of intravitreal injections of aflibercept between fixed dosing (FD) regimen and a pro re nata (PRN) regimen after three initial monthly doses for the treatment of polypoidal choroidal vasculopathy and to analyze factors influencing improvement in visual acuity. METHODS: We retrospectively studied all treatment-naive patients with polypoidal choroidal vasculopathy who were scheduled to receive intravitreal aflibercept injections FD or PRN after induction treatment between March 2013 and May 2014. Best-corrected visual acuity was evaluated before treatment and at 4, 12, 24, and 36 months after initial treatment. Factors that influence improvement in visual acuity were also investigated. RESULTS: Thirty-three eyes were assessed at the 3-year follow-up examination. Twenty-three eyes were treated with intravitreal aflibercept injections every 2 months for at least 1 year after three initial monthly doses (FD group), and 10 eyes were treated PRN after loading doses (PRN group). In the FD group, during the follow-up period from 1 to 3 years, quarterly dosing with capped PRN or a treat and extend regimen were selected. The mean number of administered intravitreal aflibercept was 15.3 ± 4.6 in the FD group and 9.0 ± 8.9 in the PRN group, with a significant difference between the two groups (P = 0.004). Significant improvement of the mean logarithm of the minimum angle of resolution values for best-corrected visual acuity was shown at 36 months, as compared to baseline values (P = 0.019). No significant difference in the improvement of best-corrected visual acuity between the two groups was observed at baseline or at 4, 12, 24, and 36 months after treatment (all P > 0.05), although there was a trend toward better results in the FD group. Multiple regression analysis showed that the FD group had better visual acuity at 36 months and greater improvement in visual acuity than the PRN group (P = 0.031 for both comparisons). CONCLUSION: Intravitreal aflibercept was effective in improving the vision of patients with polypoidal choroidal vasculopathy, as evaluated at the 3-year follow-up. Fixed treatment might be an important factor influencing improvement in visual acuity.

RESUMO

PURPOSE: The aim of this study was to evaluate the one-year efficacy, ability to lower intraocular pressure, and tolerability of ripasudil, a rho-kinase inhibitor, in patients with glaucoma inadequately controlled with maximum medical therapy. METHODS: This prospective, non-comparative, interventional case-series study included 39 patients with primary open-angle glaucoma inadequately controlled with maximum medical therapy before treatment with ripasudil. Ripasudil was administered twice per day as adjunctive therapy to ongoing glaucoma treatment. The primary endpoint was the degree of intraocular pressure reduction after 12 months of treatment; the secondary endpoints were the incidence of adverse events. RESULTS: We examined 39 eyes. The intraocular pressure reduction (given as the relative percentage of intraocular pressure reduction) from baseline was -2.6 mmHg (-15.5%; 95% confidence interval, -1.1 to -3.9 mmHg; P < 0.001) after 12 months of treatment. The adverse events were conjunctival hyperemia (all patients), blepharitis (three), allergic conjunctivitis (two), punctate keratitis (two), and ophthalmalgia (one). CONCLUSIONS: Treatment with ripasudil decreased intraocular pressure in patients with glaucoma that was poorly controlled with maximal medical therapy, and it was well-tolerated.

RESUMO

PURPOSE: To report the clinical outcomes of a new technique for transconjunctival intrascleral fixation of an intraocular lens (IOL). DESIGN: Prospective, noncomparative, interventional case series. PARTICIPANTS: One hundred eyes of 97 consecutive patients with aphakia, dislocated IOL, or subluxated crystalline lens who underwent posterior chamber sutureless implantation of an IOL were studied. METHODS: Two angled incisions parallel to the limbus were made by 30-gauge thin-wall needles. Haptics of an IOL were externalized with the needles and cauterized to make a flange of the haptics. The flange of the haptics were pushed back and fixed into the scleral tunnels. MAIN OUTCOME MEASURES: Best-corrected visual acuity (VA), corneal endothelial cell density, IOL tilt, and complications were determined. RESULTS: The IOLs were fixed with exact centration and axial stability. The mean preoperative best-corrected VA was 0.25 logarithm of the minimum angle of resolution (logMAR) units; after surgery, it improved significantly to 0.11 logMAR, 0.09 logMAR, 0.12 logMAR, and 0.04 logMAR at 6, 12, 24, and 36 months, respectively (P < 0.01, P < 0.01, P = 0.03, and P = 0.10, respectively). The mean corneal endothelial cell density decreased from 2341 cells/mm2 before surgery to 2313 cells/mm2, 2240 cells/mm2, 2189 cells/mm2, and 2244 cells/mm2 at 6, 12, 24, and 36 months, respectively (P < 0.01, P < 0.01, P < 0.01, and P = 0.17, respectively). The mean IOL tilt was 3.4°±2.5°. The postoperative complications included iris capture by the IOL in 8 eyes (8%), vitreous hemorrhage in 5 eyes (5%), and cystoid macular edema in 1 eye (1%). There were no incidents of postoperative retinal detachment, endophthalmitis, or IOL dislocation. CONCLUSIONS: We have developed a new technique for intrascleral IOL fixation. The flanged IOL fixation technique is a simple and minimally invasive method for achieving good IOL fixation with firm haptic fixation.
