To investigate the long-term outcomes of cataract surgery for glaucoma management in patients with primary angle-closure disease (PACD).Retrospective case series.We reviewed the medical records of 87 eyes of 87 patients with PACD who underwent uncomplicated cataract surgery alone at the Kobe City Medical Center General Hospital. Only patients with a minimum follow-up of 10 years were included. The patients were divided into PACD spectrum categories: primary angle-closure glaucoma (PACG), primary-angle closure (PAC), and primary angle-closure suspect (PACS). The treatment outcomes were compared among the 3 groups. Intraocular pressure (IOP), number of glaucoma eye drops, requirement of additional glaucoma treatment, visual field progression, and progression to glaucoma during the follow-up period were evaluated.Among the 87 patients, 39 had PACG; 26, PAC; and 22, PACS. Ten years after surgery, the IOP had significantly decreased from baseline in all 3 groups. The rate of requirement of additional glaucoma treatment during the follow-up period was significantly higher in the PACG group than in the other groups. Almost half of the patients with PACG required additional glaucoma treatment; of those patients, six (15.4%) underwent glaucoma surgery. Three patients (11.5%) with PAC required additional glaucoma medication. Visual field progression was observed in 28.1% of the patients with PACG. In 1 patient with PAC, the condition progressed to PACG, but there was no such progression in any of the patients with PACS.We confirmed that cataract surgery had a long-term ( 10 years) effect on IOP reduction in eyes with PACD. Early intervention with cataract surgery may be preferable for glaucoma management in patients with PACD.

AIM: To investigate the one-year outcomes and factors that influence the results of microhook ab interno trabeculotomy (µLOT). METHODS: The medical records of consecutive patients with open angle glaucoma who underwent µLOT (including combination of µLOT and cataract surgery) between February 2018 and July 2019 were retrospectively reviewed. Surgical success was defined as the following: an intraocular pressure (IOP)≤21 mm Hg or IOP≤preoperative IOP with a reduced number of glaucoma eye drops, without additional glaucoma surgery, and assessed using Kaplan-Meier survival analysis. A multivariate Cox proportional-hazards regression model was used to investigate the factors associated with surgical failure. RESULTS: The 59 eyes of 59 patients comprising 28 eyes with primary open angle glaucoma (POAG) and 31 with secondary open angle glaucoma (SOAG) were included. The mean IOP and number of glaucoma eye drops significantly decreased from 25.3±7.2 mm Hg and 3.9±1.1, preoperatively to 16.1±4.4 mm Hg (P25 mm Hg within 2wk post-surgery; P

Immune attacks are key issues for cell transplantation. To assess the safety and the immune reactions after iPS cells-derived retinal pigment epithelium (iPS-RPE) transplantation, we transplanted HLA homozygote iPS-RPE cells established at an iPS bank in HLA-matched patients with exudative age-related macular degeneration. In addition, local steroids without immunosuppressive medications were administered. We monitored immune rejections by routine ocular examinations as well as by lymphocytes-graft cells immune reaction (LGIR) tests using graft RPE and the patient&rsquo, s blood cells. In all five of the cases that underwent iPS-RPE transplantation, the presence of graft cells was indicated by clumps or an area of increased pigmentation at 6 months, which became stable with no further abnormal growth in the graft during the 1-year observation period. Adverse events observed included corneal erosion, epiretinal membrane, retinal edema due to epiretinal membrane, elevated intraocular pressure, endophthalmitis, and mild immune rejection in the eye. In the one case exhibiting positive LGIR tests along with a slight fluid recurrence, we administrated local steroid therapy that subsequently resolved the suspected immune attacks. Although the cell delivery strategy must be further optimized, the present results suggest that it is possible to achieve stable survival and safety of iPS-RPE cell transplantation for a year.

Purpose: To report 2 years’ longitudinal retinal changes using spectral domain optical coherence tomography (SD-OCT) images in a case of retinitis after influenza virus infection. Observations: A 48-year-old female complained of scotoma in the central visual field after influenza virus infection. Her best visual acuity was 20/16, her fundus examination was normal, and fluorescein angiography demonstrated no evident leakage in either the retina or the optic disc. However, SD-OCT images showed a disrupted, blurred inner-segment ellipsoid zone in the macula of both eyes. Two steroid pulse therapy sessions in the first 3 months showed temporary improvement of the central scotoma. However, atrophy of the photoreceptor layer at the juxta fovea gradually progressed in OCT images during the follow-up period. In contrast, the fovea itself was mostly intact and visual acuity was maintained in the 2-year period. Conclusions and importance: We experienced a unique case of retinitis after influenza infection, in whom progressive atrophy of the photoreceptor layer was observed in SD-OCT images.

Purpose To report the results after 4 years of follow-up in a previously presented first case of induced pluripotent stem cell (iPSC)-derived retinal pigment epithelium (RPE) sheet autologous transplantation using multimodal imaging. Design Follow-up of a single case. Participant A patient with exudative age-related macular degeneration and polypoidal choroidal vasculopathy. Methods Transplantation of an autologous iPSC-derived RPE cell sheet after removal of choroidal neovascularization (CNV) in September 2014. Main Outcome Measures The function of the graft was assessed 4 years after surgery by color fundus photography, spectral-domain (SD) OCT, fluorescein angiography, indocyanine green angiography, and an adaptive optics (AO) retinal camera. Results At the 4-year follow-up, the transplanted autologous iPSC-derived RPE sheet had survived beneath the retina with slight expansion of the pigmented area and no adverse events. The outer nuclear layer above and adjacent to the graft showed acceptable thickness and an organized structure. Fluorescein angiography and SD OCT suggested the presence of vessel-like structures confined to the grafted area associated with the remaining trunk vessel of preoperative polypoidal choroidal vasculopathy but with no exudative changes. Visual acuity has been stable with no additional injections of anti–vascular endothelial growth factor agent. The choroidal volume at the graft site is relatively preserved when compared with the volume outside this site without RPE after removal of the CNV. Indocyanine green angiography revealed a preserved choriocapillaris around the iPSC-derived RPE sheet. Dark cell-like structures with a predominantly hexagonal arrangement were observed by AO imaging in an area located near the margin of the graft sheet. The average intercell distance was found to be stable over time. Conclusions Thus far, the grafted iPSC-derived RPE sheet has survived for 4 years and seems to support photoreceptors and choroidal vessels. The morphologic characteristics of the RPE are observed at the transplant site.

We assessed the feasibility of transplanting a sheet of retinal pigment epithelial (RPE) cells differentiated from induced pluripotent stem cells (iPSCs) in a patient with neovascular age-related macular degeneration. The iPSCs were generated from skin fibroblasts obtained from two patients with advanced neovascular age-related macular degeneration and were differentiated into RPE cells. The RPE cells and the iPSCs from which they were derived were subject to extensive testing. A surgery that included the removal of the neovascular membrane and transplantation of the autologous iPSC-derived RPE cell sheet under the retina was performed in one of the patients. At 1 year after surgery, the transplanted sheet remained intact, best corrected visual acuity had not improved or worsened, and cystoid macular edema was present.

Purpose To investigate flow area changes measured using optical coherence tomography angiography (OCTA; RTVue XR Avanti®) in patients with retinitis pigmentosa (RP) with preserved visual acuity (VA). Methods This was an age‐ and refraction‐matched case–control study. Consecutive patients with a best‐corrected visual acuity (BCVA) of ≥20/20 and normal subjects were recruited. Fifty eyes (32 patients) and 22 eyes (12 controls) were included. The flow area and foveal avascular zone (FAZ) were measured in both superficial and deep layers within a 3 × 3 mm central area of the fovea. Association between OCTA parameters and the length of the inner segment ellipsoid (ISe) and external limiting membrane (ELM), the area without abnormal fluorescence in fundus autofluorescence (normal FAF area ratio) and the area of I‐2e of the Goldmann perimeter were analysed using mixed‐effects regression analysis. Results Foveal avascular zones were significantly smaller in patients with RP than in controls in superficial (p = 0.004) but not in deep layers (p = 0.25). The flow area in superficial (p = 0.007) and deep layers (p = 0.004) was significantly smaller in patients with RP than in controls. In patients with RP, flow areas in the superficial layers, but not in the deep layers, were significantly associated with the lengths of ISe (p = 0.001) and ELM (p = 0.002) and the I‐2e area (p = 0.036), but not with the normal FAF area ratio (p = 0.399). Conclusion Optical coherence tomography angiography (OCTA)‐measured flow area in superficial layers gradually reduced with RP progression and may be a useful parameter of RP pathogenesis.

To measure changes in axial length before and after trabeculectomy with noncontact, partial coherence laser interferometry and identify patient factors that lead to the development of hypotony maculopathy and axial length shortening in 25 eyes with intraocular pressure (IOP) ≤6 mmHg at 4 weeks after mitomycin C-augmented trabeculectomy. A retrospective comparative case series. Hypotony maculopathy was identified with both ophthalmoscopy and spectral-domain optical coherence tomography. Axial length and IOP were serially measured pre- and postoperatively. Logistic regression analysis was performed to identify factors associated with the presence of hypotony maculopathy at 4 weeks after trabeculectomy and multiple regression analysis to identify factors associated with axial length changes. Ten eyes exhibited hypotony maculopathy, whereas the remaining 15 did not. Patients with hypotony maculopathy were significantly younger (47.7 ± 6.2 years) compared with those without it (63.3 ± 9.6 years, P = 0.0002, unpaired t test). The percent reduction of axial length after trabeculectomy was significantly larger in the former group (5.91 ± 2.76 %) compared with the latter group (1.51 ± 0.91 %) (P = 0.0001, Mann–Whitney U test). Multivariate analyses showed that only age was associated with the presence of hypotony maculopathy, with an odds ratio of 0.82 (P = 0.0075), when age, sex, type of glaucoma, lens status, percent changes in axial length and IOP before and after trabeculectomy, and central corneal thickness were included as independent variables (R 2 = 0.543, P = 0.003). Age-dependent axial length reduction is a risk factor for the development of hypotony maculopathy after trabeculectomy.

To evaluate the long-term effects of photodynamic therapy (PDT) on typical neovascular age-related macular degeneration (tAMD) and polypoidal choroidal vasculopathy (PCV). This was a multicenter prospective study of 139 eyes from 136 patients (tAMD: 74 eyes; PCV: 65 eyes) who underwent PDT as the initial treatment. The change in best-corrected visual acuity (BCVA), predictive factors for the BCVA at 60 months, frequency of recurrence, and mean recurrence period were analyzed. The pre-PDT BCVA and greatest linear dimension (GLD) did not differ between the two groups. The mean BCVA (logMAR) was significantly improved at 6 months post-initial PDT (post-PDT) in the PCV group (−0.11, P = 0.0091). However, at 60 months post-PDT, the mean BCVA was significantly worse than baseline in the tAMD (+0.21, P = 0.0035) and PCV (+0.21, P = 0.0076) groups. Pre-PDT BCVA, age, and GLD were the factors significantly associated with the BCVA at 60 months post-PDT. Although the frequency of recurrence did not significantly differ between the two phenotype groups, the mean recurrence period was significantly longer in the PCV group than in the tAMD group (15.7 vs. 8.6 months, P = 0.0020). PDT may not have benefits for visual acuity in cases of tAMD and PCV over 5 years of follow-up.

Cholesteryl ester rich apolipoprotein B100 (apoB100) lipoproteins accumulate in Bruch's membrane before the development of age-related macular degeneration. It is not known if these lipoproteins come from the circulation or local ocular tissue. Emerging, but incomplete evidence suggests that the retinal pigmented epithelium (RPE) can secrete lipoproteins. The purpose of this investigation was to determine (i) whether human RPE cells synthesize and secrete apoB100, and (ii) whether this secretion is driven by cellular cholesterol, and if so, (iii) whether statins inhibit this response. The established, human derived ARPE-19 cells challenged with 0-0.8 mM oleic acid accumulated cellular cholesterol, but not triglycerides. Oleic acid increased the amount of apoB100 protein recovered from the medium by both western blot analysis and (35) S-radiolabeled immunoprecipitation while negative stain electron microscopy showed lipoprotein-like particles. Of nine statins evaluated, lipophilic statins induced HMG-CoA reductase mRNA expression the most. The lipophilic Cerivastatin (5 μM) reduced cellular cholesterol by 39% and abrogated apoB100 secretion by 3-fold. In contrast, the hydrophilic statin Pravastatin had minimal effect on apoB100 secretion. These data suggest that ARPE-19 cells synthesize and secrete apoB100 lipoproteins, that this secretion is driven by cellular cholesterol, and that statins can inhibit apoB100 secretion by reducing cellular cholesterol.

ObjectiveWe investigated the efficacy of additional topical betamethasone in persistent cystoid macular oedema (CMO) after carbonic anhydrase inhibitors (CAIs) therapy.Methods and analysisThis retrospective cohort study included 16 eyes of 10 patients with retinitis pigmentosa (RP). All patients were previously administered CAI for at least 3 months to treat CMO secondary to RP and lacking an effective reduction (≥11%) of central foveal thickness (CFT). We administered topical 0.1% betamethasone daily in each affected eye following a preceding course of the CAI medication as a first treatment. CMO was diagnosed using spectral-domain optical coherence tomography. CFT was regarded as the average of vertical and horizontal foveal thickness. Best-corrected visual acuity (BCVA) and intraocular pressure (IOP) were obtained from patient medical records. We compared the CFT and BCVA between baseline and the average of 1–3, 5–7, 10–14 and 16–20 months period.ResultsIn treatments with brinzolamide in 14 eyes, dorzolamide in 2 eyes and bromfenac in 2 eyes, CFT effectively decreased in 12 of 16 eyes (81%). CFT decreased significantly in 1–3 months (326±102 µm; n=16; P=0.029) and 5–7 months (297±102 µm; n=12; P=0.022) compared with baseline but not within 10–14 months (271±96 µm; n=9; P=0.485) or 16–20 months (281±134 µm; n=9; P=0.289). There were no significant intergroup differences in BCVA throughout the study. Betamethasone treatment was stopped in three patients because of IOP elevation.ConclusionOur data suggested that additional betamethasone might improve treatments for persistent CMO. Topical steroids could be an alternative option for managing persistent CMO in RP.

Uveitis is an inflammatory condition that can lead to blindness. It is therefore important to understand the pathophysiology against which to develop targeted therapy. Herein, we tested whether the oxidant-responsive transcription factor Nrf2 is involved in regulating the innate immune response and oxidative damage in the LPS uveitis model. As shown by dihydroethidium staining, intraperitoneally injected LPS increased reactive oxygen species in the retina and iris-ciliary body of Nrf2+/+ and Nrf2-/- mice. After LPS injection, ICAM-1, IL-6, TNF-alpha, COX-2, iNOS, and MCP-1 mRNAs were increased more in the retina and iris-ciliary body of Nrf2-/- than in those of Nrf2+/+ mice. NQO-1 and GCLM, two Nrf2-responsive antioxidant enzymes, had reduced expression in Nrf2+/+ retinas after LPS injection, but no change in expression in Nrf2-/- mice. The number of FITC-Con A-labeled leukocytes adherent to the retinal vascular endothelium increased after LPS treatment in both Nrf2+/+ and Nrf2-/- mice compared to control injections, with more adherent leukocytes in Nrf2-/- than in Nrf2+/+ mice. Pretreatment with the Nrf2 activator 1-(2-cyano-3,12-dioxooleana-1,9(11)-dien-28-oyl)imidazole increased antioxidant gene expression in the retina, reduced inflammatory mediator expression, and reduced leukocyte adherence to retinal vasculature after LPS treatment in Nrf2+/+ mice, but had no effect on Nrf2-/- mice. Treatment targeting the Nrf2 pathway may be a new therapy for uveitis.

ApoB100 lipoprotein particles have been found to accumulate in Bruch membrane prior to the development of Age-related macular degeneration (AMD). This work was performed to determine whether mice that overexpress apoB100 in the RPE-choroid and liver develop landmarks of early AMD over time. Mice transgenic for a human genomic fragment encoding the full length human ApoB (“ApoB100” mice) and litter-mate control mice were given a normal chow or high fat diet for 12 months. Mice were evaluated for human apoB mRNA expression in the RPE/choroid and liver by RT-qPCR. Phenotypic changes associated with early AMD were evaluated by ultrastructural analysis using transmission electron microscopy. Changes were semi-quantified using linear regression analysis. Both the RPE/choroid and liver of ApoB100 mice expressed both human and mouse ApoB mRNA. Transmission electron microscopy showed ultrastructural changes consistent with early human AMD including loss of basal infoldings and accumulation of cytoplasmic vacuoles in the RPE, and basal laminar deposits containing long spacing collagen and heterogeneous debris in Bruch membrane of ApoB100 mice. In ApoB100 mice given a high fat diet, basal linear-like deposits were identified in 12 month old mice. Linear regression analysis showed that the genotype (human ApoB transgene) was a stronger influencing factor than high fat diet in producing AMD-like lesions used in this study. Human ApoB100 transgenic mice overexpress apoB in RPE and, with time, develop validated phenotypic changes that are seen in early human AMD. The phenotypic changes were aggravated by feeding a high-fat diet. The ApoB100 mouse model could be valuable in determining the role of apoB containing lipoproteins in triggering the onset of early AMD.

To investigate the frequency of residual angle closure after resolution of pupillary blocking by laser peripheral iridotomy and the effects of subsequent cataract surgery to resolve angle closure completely.Retrospective, consecutive, interventional study.Among 70 eyes treated with laser iridotomy, 13 with residual angle closure were treated with cataract surgery.The provocative test of angle closure by prone position in a dark room for 1 hour was performed; increases in tension ofor =8 mmHg, 6 or 7 mmHg, andor =5 mmHg were considered to be positive, suspected positive, and negative, respectively. Configuration of the anterior chamber was examined using ultrasound biomicroscopy (UBM).Intraocular pressure (IOP), response to the dark room prone position test, and morphologic analysis by UBM were evaluated before and 3 months after cataract surgery.Residual angle closure after iridotomy was seen in 27 (38.6%) of 70 eyes; this was confirmed functionally by the dark room prone position test and morphologically by UBM. Eyes with IOP ofor =20 mmHg or with a glaucomatous visual field defect before iridotomy had a significantly higher incidence of residual angle closure after iridotomy than eyes without these findings (P0.05). In all the eyes with residual angle closure after iridotomy, the response to the prone position test became negative after cataract surgery, with significant lowering of IOP (P0.01).Residual angle closure after iridotomy was common, especially in eyes with primary angle closure and poorly controlled IOP or glaucomatous optic neuropathy. Cataract surgery was effective to resolve completely the residual angle closure after iridotomy and lower IOP.

Purpose To compare the ability of circumpapillary retinal nerve fiber layer (cpRNFL) thickness and macular parameters obtained by three spectral-domain optical coherence tomography (SD-OCT) instruments to detect highly myopic glaucoma. Methods In this study, 84 glaucomatous eyes, 53 normal eyes with high myopia, and 86 normal eyes (not highly myopic) were enrolled. Each participant was imaged using Cirrus, RTVue, and 3D OCT to evaluate the average and quadrant cpRNFL thicknesses. The macular retinal nerve fiber layer (mRNFL), ganglion cell layer + inner plexiform layer (GCL/IPL), and mRNFL + GCL/IPL (GCC) thicknesses were analyzed. The areas under the receiver operating characteristic curves (AUCs) were compared between the instruments. In addition, the best parameters for the AUC were compared between the cpRNFL parameters and macular parameters in each instrument. Results These analyses revealed similar AUCs for the average cpRNFL and GCC thicknesses between the instruments. RTVue displayed a significantly higher AUC in the nasal cpRNFL thickness than both Cirrus (P = 0.0004) and 3D OCT (P = 0.0006). 3D OCT showed higher AUCs than Cirrus in the mRNFL parameters. There were no significant differences between the best cpRNFL parameters and macular parameters in each instrument. Conclusions The average cpRNFL and GCC thicknesses that were measured using these OCT instruments exhibited similar abilities for diagnosing highly myopic glaucoma, and RTVue exhibited better diagnostic abilities than Cirrus and 3D OCT for nasal cpRNFL. 3D OCT had better ability than Cirrus in the mRNFL. Both cpRNFL and GCC in each instrument were comparable, and their measurements offered good ability for diagnosing glaucoma with high myopia. (http://www.umin.ac.jp/ctr/index/htm9, UMIN000006900.).

Purpose In eyes with primary angle closure (PAC), we quantitatively evaluated anterior bowing of the iris by means of ultrasound biomicroscopy (UBM). Design Retrospective, observational, and consecutive case series. Methods A total of 203 phakic eyes with PAC that had not undergone any surgical or laser treatment were included. Using UBM, we measured anterior chamber depth (ACD) and iris convexity (IC): the maximum distance from the posterior surface of the iris to the iris plane passing through the pupillary margin of the iris and iris root. Results The average IC was 0.22 ± 0.1 mm, although there was considerable individual variation. The IC value was correlated weakly, albeit significantly, with age ( r = 0.22, P r = −0.57, P Conclusions In eyes with PAC, older age and a more shallow ACD appear to be important causes of increased forward bowing of the iris resulting from pupillary block.

Methanol is a highly toxic substance used as an industrial solvent and automotive antifreeze. Human consumption of methanol may result in severe visual disturbances. Because optical coherence tomography (OCT) is very useful for evaluating retinal edema and nerve fiber swelling, we used OCT to examine a patient with methanol-induced retinal toxicity. A 37-year-old man who drank industrial alcohol (100 ml/day) for 4 days. The retinal profiles were evaluated by OCT and fluorescein angiography during the course of treatment. OCT demonstrated peripapillary nerve fiber swelling and accumulation of intraretinal fluid in the acute phase. In the chronic phase, the retinal thickness was diffusely decreased. Steroid pulse therapy was not effective, and his visual acuity was 6/200 OD and 4/100 OS 2 years after the event. OCT was very useful for evaluating the severity of the retinal edema and the temporal changes in the retinal profile. Jpn J Ophthalmol 2006;50:239–241 © Japanese Ophthalmological Society 2006

Neovascular glaucoma (NVG) occurring after branch retinal artery occlusion (BRAO) might not be as rare as previously thought. We report a case of unilateral NVG after BRAO. A 72-year-old man with chronic heart failure suffered from BRAO in the left eye. Funduscopic examination showed retinal edema and many cotton wool spots in the superotemporal retina. Five weeks later, he had increased blurring of vision due to a second BRAO in the inferotemporal retina of the left eye. Three days later, he felt pain and had severe visual loss in the left eye. In the presence of angle neovascularization, intraocular pressure (IOP) in the left eye rose to 35 mmHg. Immediate focal photocoagulation to the affected retina diminished the neovascularization and lowered the IOP. It is possible for NVG to occur as a complication of BRAO.

Purpose We compared the ability of circumpapillary retinal nerve fiber layer (cpRNFL) thickness and macular parameters obtained by three spectral-domain optical coherence tomography (SD-OCT) instruments to detect glaucoma. Methods We enrolled 87 normal eyes and 145 glaucomatous eyes (75 early glaucomatous eyes (EGs), mean deviation > -6 dB). Each participant was imaged using Cirrus, RTVue, and 3D-OCT to evaluate the average and quadrant cpRNFL thicknesses. The macular retinal nerve fiber layer (mRNFL), ganglion cell layer plus inner plexiform layer (GCL/IPL), and mRNFL + GCL/IPL (ganglion cell complex [GCC]) thicknesses were analyzed. The areas under the receiver operating characteristic curves (AUCs) were compared among the instruments. Results These instruments revealed similar AUCs for the average cpRNFL and GCC thicknesses in EGs, and total all-stage glaucomatous eyes (TGs). RTVue showed better performance in the nasal cpRNFL thickness than Cirrus and 3D-OCT, and better performance in the temporal cpRNFL thickness than 3D-OCT in TGs. RTVue had a higher AUC for the superior GCC thickness compared to Cirrus and 3D-OCT in EGs, and TGs. Cirrus had higher AUCs for GCL/IPL parameters in TGs, and lower AUCs for the mRNFL parameters in EGs and TGs compared to 3D-OCT. Conclusions The average cpRNFL and GCC thicknesses measured using these OCT instruments exhibited similar abilities in the diagnosis of glaucoma, and RTVue exhibited better diagnostic abilities than Cirrus and 3D-OCT for nasal cpRNFL, and superior GCC thicknesses. The diagnostic performance of Cirrus and 3D-OCT was different for GCL/IPL and mRNFL parameters. (http://www.umin.ac.jp/ctr number, UMIN000006900.)

Patients with baseline best corrected visual acuity (BCVA) under 20/400 and with a greatest linear dimension of lesion over 4500 µm were excluded from the study. Twenty-six eyes from 25 patients were treated with three consecutive intravitreal injections of pegaptanib (IVP group) and 55 eyes from 54 patients were treated with three consecutive ranibizumab injections (IVR group). Each therapy was repeated as needed. The alteration in BCVA was evaluated in the IVP and IVR groups.Results: No differences were detected in baseline parameters between the IVP and IVR groups. The mean BCVA (logMAR) at month 1, 3, 6 and 12 after the initial treatment was improved from baseline in the IVP group (-0.095, -0.17, -0.18 and -0.18, respectively) and in the IVR group (-0.077, -0.15, -0.17 and -0.11, respectively), which was statistically significant. There was no difference in the change in mean BCVA between IVP and IVR groups at the same time periods.Conclusions: The visual outcome of IVP was equivalent with IVR in exudative AMD with small lesion size.Keywords: pegaptanib, ranibizumab, age-related macular degeneration, small lesion size

Age-related Macular Degeneration (AMD) is the leading cause of blindness among the elderly. While excellent treatment has emerged for neovascular disease, treatment for early AMD is lacking due to an incomplete understanding of the early molecular events. Cigarette smoking is the strongest epidemiologic risk factor, yet we do not understand how smoking contributes to AMD. Smoking related oxidative damage during the early phases of AMD may play an important role. This review explores how cigarette smoking and oxidative stress to the retinal pigmented epithelium (RPE) might contribute to AMD, and how the transcription factor Nrf2 can activate a cytoprotective response.

Purpose Mice typically produce apolipoprotein B (apoB)-48 and not apoB100. Apolipoprotein B100 accumulates in Bruch's membrane prior to basal deposit and drusen formation during the onset of AMD, raising the possibility that they are a trigger for these Bruch's membrane alterations. The purpose herein, was to determine whether mice that predominantly produce apoB100 develop features of AMD. Methods The eyes of mice that produce apoB100 were examined for apoB100 synthesis, cholesteryl esterase/filipin labeling for cholesteryl esters, and transmission electron microscopy for lipid particles and phenotype. Results Apolipoprotein B100 was abundant in the RPE-choroid of apoB100, but not wild-type mice by Western blot analysis. The apolipoprotein B100,(35)S-radiolabeled and immunoprecipitated from RPE explants, confirmed that apoB100 was synthesized by RPE. Apolipoprotein B100, but not control mice, had cholesteryl esters and lipid particles in Bruch's membrane. Immunoreactivity of ApoB100 was present in the RPE and Bruch's membrane, but not choroidal endothelium of apoB100 mice. Ultrastructural changes were consistent with aging, but not AMD when aged up to 18 months. The induction of advanced glycation end products to alter Bruch's membrane, did not promote basal linear deposit or drusen formation. Conclusions Mice that produce apoB100 in the RPE and liver secrete lipoproteins into Bruch's membrane, but not to the extent that distinct features of AMD develop, which suggests that either additional lipoprotein accumulation or additional factors are necessary to initiate their formation.

Purpose To review the efficacy of a combination of triamcinolone acetonide (TA) injection and pars plana vitrectomy (PPV) for the treatment of macular edema associated with branch retinal vein occlusion (BRVO). Methods Seventeen eyes with macular edema associated with BRVO underwent PPV with an intraoperative injection of TA (10 mg) into the vitreous cavity. Residual or recurrent macular edema was treated with postoperative sub-Tenon capsule injections of TA (20 mg). Results With PPV and an intraoperative injection of TA, 82% of eyes showed rapid reduction of macular edema; foveal thickness decreased from 507 +/- 115 microm preoperatively to 261 +/- 123 microm 2 months after surgery (P = 0.0041). However, 59% of eyes showed recurrence of macular edema during the follow-up period. Twelve eyes with residual or recurrent macular edema received sub-Tenon capsule injections of TA; of these eyes, 9 showed substantial reduction of macular edema. Foveal thickness decreased from 381 +/- 102 microm to 256 +/- 56 microm (P = 0.0076) 2 weeks after postoperative injections of TA. At the final visit, visual acuity (logMAR) improved from 0.74 +/- 0.40 preoperatively to 0.40 +/- 0.34 (P = 0.010). Conclusion An intraoperative injection of TA in combination with PPV has the potential to facilitate the absorption of macular edema associated with BRVO. In addition, residual or recurrent macular edema can be treated with additional sub-Tenon capsule injections of TA.

To evaluate quantitatively, by means of ultrasound biomicroscopy (UBM), changes in the anterior segment configuration, including the ciliary processes, induced by cataract surgery in eyes with primary angle closure.Retrospective interventional case series.Thirty-one eyes of 31 patients with primary angle closure or primary angle-closure glaucoma were treated with cataract surgery. Before cataract surgery, 10 eyes had been treated with laser peripheral iridotomy, and 1 with laser peripheral iridoplasty.Configuration of the anterior chamber was examined by means of UBM before and at 3 months after cataract surgery.Using UBM, anterior chamber depth (ACD), angle opening distance at points 500 mum from the scleral spur (AOD500), and trabecular-ciliary process distance (TCPD) were measured.Not only ACD and AOD500, but also TCPD, increased significantly after cataract surgery, compared with measurements obtained before surgery (P0.001). Postoperative AOD500 was correlated significantly with postoperative TCPD (r = 0.72, P0.001) and with the amount of change of TCPD caused by cataract surgery (Delta TCPD) (r = 0.52, P0.01).Cataract surgery attenuated anterior positioning of the ciliary processes in eyes with primary angle closure, concomitant with significant widening of the angle. Cataract surgery resulted in not only complete dissolution of lens volume and pupillary block, but also attenuation of the anterior positioning of the ciliary processes, all of which contributed to postoperative widening of the angle in eyes with primary angle closure.

Purpose Exudative retinal detachment in acute Vogt-Koyanagi-Harada syndrome often is associated with subfoveal yellowish round structures. This report describes the incidence and clinical characteristics of these structures. Design Interventional case series. Methods We reviewed the fundus photographs and medical records of 35 eyes of 19 Japanese patients with bilateral diffuse choroiditis at the onset of acute Vogt-Koyanagi-Harada syndrome. Results All eyes showed subretinal fluid in the posterior pole. In addition, yellowish round structures were seen in 15 eyes (43%). Most of the yellowish structures were subfoveal in location and ranged in size from less than 1 disk diameter to 3 disk diameters. In 6 eyes with these structures, optical coherence tomography showed liquid accumulation in the retina or thin walls, which seemed to separate the cystoid spaces from the subretinal fluid. Late-phase fluorescein angiography showed pooling of dye within these structures as well as within the subretinal fluid. Immediately after corticosteroid administration was initiated, these structures began to be less obvious, and they disappeared completely within several days; there was a concomitant reduction in the subretinal fluid. At the initial visit, visual acuity in eyes with these yellowish structures was slightly less than that in eyes without them, but no differences in visual acuity were found during the period of follow-up. Conclusion Subfoveal yellowish round structures may be a common feature in acute Vogt-Koyanagi-Harada syndrome. However, they appear to have only a minor (if any) effect on visual prognosis.

To compare the effect of photodynamic therapy (PDT) and intravitreal ranibizumab in patients with polypoidal choroidal vasculopathy (PCV).Randomized clinical trial.Multicenter.Total of 93 patients with treatment-naïve PCV.Patients were randomized to 2 arms. Patients in the PDT arm underwent a single session of PDT with verteporfin, and patients in the ranibizumab arm received 3 monthly ranibizumab injections at baseline. Additional treatment was performed as needed in each arm.Primary outcome measurement was the proportion of patients gaining or losing more than 0.2 logarithm of minimal angle of resolution (logMAR) units from baseline. Mean change of logMAR and central retinal thickness (CRT) were also evaluated.In the PDT arm (n = 47), 17.0% achieved visual acuity gain, 55.3% had no change, and 27.7% experienced visual acuity loss. The results were 30.4%, 60.9%, and 8.7%, respectively, in the ranibizumab arm (n = 46), significantly better than the PDT arm (P = .039). In the PDT arm, mean CRT improved (366.8 ± 113.6 μm to 289.1 ± 202.3 μm, P.001), but logMAR was unchanged (0.57 ± 0.31 to 0.62 ± 0.40). The ranibizumab arm demonstrated improvement in both CRT (418.9 ± 168.6 μm to 311.2 ± 146.9 μm, P.001) and logMAR (0.48 ± 0.27 to 0.39 ± 0.26, P = .003). Mean change of logMAR was also greater in the ranibizumab arm (P = .011).Intravitreal injection of ranibizumab is more effective than PDT for treatment-naïve PCV.

PURPOSE. Using spectral-domain optical coherence tomography (SD-OCT), we assessed the ability of cluster analyses, based on the grid-pattern of macular parameters, to detect glaucoma. METHODS. We enrolled 75 normal eyes, 64 early glaucomatous eyes (EG), and 40 preperimetric glaucomatous eyes (PPG). Each participant was imaged using 3-dimensional optical coherence tomography (3D-OCT) to examine the macular retinal nerve fiber layer (mRNFL) and the thickness of the ganglion cell layer, together with the inner plexiform layer (GCL/IPL). Diagnostic criteria based on the clustering of abnormal grids from the mRNFL and GCL/IPL measurements were applied. The sensitivity and specificity of glaucoma detection were compared between the cluster criteria (CC) and the average thickness criteria (ATC) of total and hemiretinal sectors, and the cut-off criteria were determined using receiver operating characteristic (ROC) curve analyses from our normal controls. RESULTS. The specificity values of CC and ATC from mRNFL measurements were 97% and 100%, respectively. The sensitivity of CC was 94% for EG and 68% for PPG. The sensitivity of ATC was 81% for EG and 38% for PPG. The specificity values of CC and ATC from GCL/IPL measurements were 96% and 100%, respectively. The sensitivity values of CC and ATC were 92% for EG and 63% for PPG. The sensitivity of ATC was 84% for EG and 25% for PPG. When compared to ATC and ROC-based cut-off criteria, CC showed a higher diagnostic capability. CONCLUSIONS. Judging abnormality based on a clustering of abnormal grids from macular OCT parameters may be a reliable approach for diagnosing early glaucoma.

The purpose of this study was to determine whether mice exposed to chronic cigarette smoke develop features of early age-related macular degeneration (AMD). Two month old C57Bl6 mice were exposed to either filtered air or cigarette smoke in a smoking chamber for 5 h/day, 5 days/week for 6 months. Eyes were fixed in 2.5% glutaraldehyde/2% paraformaldehyde and examined for ultrastructural changes by transmission electron microscopy. The contralateral eye was fixed in 2% paraformaldehyde and examined for oxidative injury to the retinal pigmented epithelium (RPE) by 8-oxo-7,8-dihydro-2'-deoxyguanosine (8-OHdG) immunolabeling and apoptosis by TUNEL labeling. Mice exposed to cigarette smoke had immunolabeling for 8-OHdG in 85+/-3.7% of RPE cells counted compared to 9.5+/-3.9% in controls (p
