BACKGROUND: The aim of this work was to compare the efficacy of intravitreal dexamethasone implant (Ozurdex) and intravitreal ranibizumab (Lucentis) in the treatment of macular edema (ME) caused by retinal vein occlusion (RVO). METHODS: Thirty-two ME cases treated with Ozurdex and 32 ME cases treated with ranibizumab were enrolled, with 26 central (C)RVO and 6 branch (B)RVO subjects in each group. We compared the results of best-corrected visual acuity (BCVA), central retinal thickness, number of injections, and intraocular pressure (IOP) at 1, 2, 3, and 6 months after injection...

AIM: We aimed to analyze the effects of adjunctive posterior sub-Tenon capsule triamcinolone acetonide injection in the treatment of intermediate uveitis macular edema in multiple sclerosis patients that could not be controlled by systemic corticosteroid medications and immunomodulators. METHODS: The study included 30 eyes of 25 patients with multiple sclerosis who received a posterior sub-Tenon injection of 40 mg/mL triamcinolone acetonide. Parameters monitored for therapy efficiency were best-corrected visual acuity, intraocular pressure, central foveal thickness (CFT), and fluorescein angiography (FA) scores...

PURPOSE: To investigate the effect of vitreomacular adhesion (VMA) on the outcome of antiangiogenic treatment for neovascular age-related macular degeneration (AMD). METHODS: Ninety-nine eyes of 83 patients were used in our cohort study. We prospectively evaluated best corrected visual acuity (BCVA) and central retinal thickness (CRT) in patients with neovascular AMD at baseline and 1, 2, 3, 6, and 12 months after treatment with anti-vascular endothelial growth factor (anti-VEGF) agents...

BACKGROUND: We assessed bleb morphology and the intraocular pressure (IOP)-lowering effect of trabeculectomy with ologen compared to mitomycin C (MMC) in juvenile open-angle glaucoma (JOAG). METHODS: This is a prospective interventional comparative study conducted on 40 eyes (20 patients) with medically uncontrolled JOAG, randomly operating one eye for trabeculectomy with ologen (group A: 20 eyes) and the other with MMC (group B: 20 eyes). IOP measurement, SITA standard perimetry, and spectral domain optical coherence tomography (OCT) for retinal nerve fiber layer (RNFL) thickness were all done pre- and postoperatively...

PURPOSE: To evaluate a new nuclear cataract grading system which is intended as a surgical guidance system to predict lens hardness before cataract surgery. METHODS: The new BCN 10 grading system consists of frontal and cross-sectional slit-lamp images of human eye lenses, ranging from a completely transparent lens nucleus to a totally black nuclear cataract. Validation was done with 9 observers for 110 cases. Two modalities were applied, and observers were asked to use only whole digits and then half digits for grading...

PURPOSE: To compare endothelial cell (EC) variation after anterior chamber phakic intraocular lens (AC-pIOL) implantation in highly myopic patients with a preoperative anterior chamber depth (ACD) between 2.8 and 3.0 versus ≥3.0 mm. METHODS: A total of 280 eyes submitted to primary AC-pIOL implantation were analyzed. Pre- and postoperative values for uncorrected distance visual acuity, corrected distance visual acuity, spherical equivalent, ACD (endothelial surface), and EC count were collected...

PURPOSE: To determine the relationship between the rate of glaucomatous visual field loss and the amplitude of a 24-h intraocular pressure (IOP)-related profile measured using a contact lens sensor (CLS). METHODS: This observational study included 22 patients with glaucoma and an IOP of consistently ≤21 mm Hg during office hours. All subjects underwent Goldmann tonometry, standard automated perimetry (SAP), dilated fundus examination, and had a CLS recording. A cosine function was used to obtain peak (acrophase), trough (bathyphase), and amplitude measurements...

PURPOSE: In normal tension glaucoma (NTG), factors other than elevated intraocular pressure are likely to have a role in the pathogenesis of optic neuropathy. Recent studies of glaucoma or retinal ganglion cells (RGCs) reveal that the cytokine interleukin-6 (IL-6) is linked to the pathogenesis of glaucoma and may regulate RGC survival or death. The IL-6 (-174) G allele has also been shown to increase the IL-6 protein. We hypothesized that the IL-6 (-174) polymorphism may be a predisposing genetic factor affecting the severity of glaucoma...

PURPOSE: Retinal pigment epithelium (RPE) cell dysfunction is essential to the development of retinal degenerative disease. This study was designed to investigate how spliced X-box-binding protein 1 (XBP1s) regulates different modes of RPE cell death in vitro. METHODS: Human ARPE19 cells were incubated with 25 μM N-retinylidene-N-retinylethanolamine (A2E) and irradiated with blue light. Expressions of glucose-regulated protein 78 (GRP78) and XBP1s were detected by real-time quantitative PCR and Western blot...

OBJECTIVES: To analyse drug development for open-angle glaucoma during the last 20 years. METHODS: Research was performed by referring to clinical trials registered at the International Clinical Trials Registry Platform (ICTRP). A search for the condition "open-angle glaucoma" with the intervention "drug" was performed. We included trials registered from 01/01/1995 to 01/01/2015, only involving studies in phases 1, 2, and 3. Only studies resorting to novel treatment strategies (either novel drugs or yet-untested fixed associations of approved medication) were considered...

OBJECTIVES: To compare the circumpapillary retinal nerve fiber layer (cpRNFL) and the macular ganglion cell-inner plexiform layer (GCIPL) in glaucoma patients at different disease stages and to evaluate correlations between optical coherence tomography (OCT) parameters with central visual function and visual field (VF) indexes. PATIENTS AND METHODS: One hundred forty patients were included in this prospective cross-sectional study. Subjects diagnosed with chronic open-angle glaucoma and 20/40 or better vision were recruited and classified as having early, moderate, or severe VF defects based on Hodapp-Parrish-Anderson criteria...

OBJECTIVE: This study aimed to identify differentially expressed microRNAs (miRNAs) and to explore their potential roles in form-deprivation myopia. METHODS: The microarray data set GSE58124 of miRNAs was downloaded from the Gene Expression Omnibus, and form-deprivation myopia was induced in C57BL/6J mice over the right eye; the contralateral, left eyes were used as controls. Differential expression analysis was done using the LIMMA package. miRDB was used to predict targets for miRNAs...

PURPOSE: The aim of this study was to assess the effectiveness and safety of ILUVIEN® in patients with chronic diabetic macular edema (DME) who were insufficiently responsive to prior therapies. METHODS: This is a prospective, nonrandomized, multicenter, open-label, phase 4 pilot study assessing the effectiveness and safety of ILUVIEN® involving 12 patients insufficiently responsive to available therapies. Assessments were performed at screening, baseline, week 1, and months 1, 3, 6, 9, and 12...

To evaluate the role of microRNA-126 (miR-126) in maintaining the integrity of the blood-retina barrier (BRB), we established a mouse model of oxygen-induced retinopathy (OIR) and measured the retinal levels of miR-126 using recombinant plasmid pCMV-MIR or pCMV-MIR-126 intravitreal injections. We also detected VCAM-1 and BCL2L11 levels. Retinal vaso-obliteration, VCAM-1 localization on retinal endothelial cells, the blood-retina vascular permeability or albumin leakage in retinas, TUNEL histology, Evans blue assays, or Western blotting for detecting albumin or tight junction levels in the retina was performed...

Small RNA (microRNA or miRNA) is a kind of small noncoding single-stranded RNA that regulates complementary mRNA at the posttranscriptional level in eukaryotic organisms. As important regulatory factors, miRNAs play an important role in the occurrence and development of glaucoma and widely participate in regulating biological processes of glaucoma-related genes. This article reviews the connection between the aqueous humor, trabecular meshwork, the apoptosis of retinal ganglion cells, and miRNA.
