PURPOSE: Our purpose was to use deep learning for the automated detection of age-related macular degeneration (AMD) in spectral domain optical coherence tomography (SD-OCT). METHODS: A total of 1112 cross-section SD-OCT images of patients with exudative AMD and a healthy control group were used for this study. In the first step, an open-source multi-layer deep convolutional neural network (DCNN), which was pretrained with 1.2 million images from ImageNet, was trained and validated with 1012 cross-section SD-OCT scans (AMD: 701; healthy: 311)...

PURPOSE: Our purpose was to evaluate the clinical safety and efficacy of CO2 laser-assisted sclerectomy surgery (CLASS) with Mitomycin C (MMC) in open angle glaucoma (OAG). METHODS: This was a prospective, uncontrolled, interventional case series. All subjects underwent CLASS procedure by a single surgeon. After the dissection of a partial thickness scleral flap, topical MMC 0.2 mg/ml was applied to the sclera and the conjunctiva for 3 min. The CO2 laser with a beam-manipulating system was used to ablate the scleral tissue and expose the Schlemm's canal area...

PURPOSE: Our purpose was to determine the changes in anterior chamber depth (ACD) and central lens thickness (CLT) during pharmacologically induced accommodation. METHODS: Following pupillary dilation with phenylephrine 10%, baseline auto-refractions and swept-source optical coherence tomographic biometric images (Zeiss IOLMaster 700) were obtained from the right eyes of 25 subjects aged 19 to 24 years. Pilocarpine 4% and phenylephrine 10% were then instilled into these right eyes...

PURPOSE: Intravitreal injections with anti-vascular endothelial growth factor (anti-VEGF) medications have become the standard of care for their respective indications. Optical coherence tomography (OCT) scans of the central retina provide detailed anatomical data and are widely used by clinicians in the decision-making process of anti-VEGF indication. In recent years, significant progress has been made in artificial intelligence and computer vision research. We trained a deep convolutional artificial neural network to predict treatment indication based on central retinal OCT scans without human intervention...

PURPOSE: The evaluation of a non-invasive detection method for human papilloma virus (HPV) in ophthalmic pterygia. METHODS: Cotton swab samples and corresponding tissue specimens were collected from 21 ophthalmic pterygia of 21 patients. HPV detection and typing were performed by real-time PCR. Discrepancies in HPV detection between swab and tissue samples as well as clinical correlations of findings were examined. RESULTS: HPV DNA was detected in 9 (42...

PURPOSE: The purpose of this study was to evaluate the safety and efficacy of dexamethasone intravitreal implant 0.7 mg (DEX) for treatment of macular edema associated with retinal vein occlusion (RVO). METHODS: This study was a six-month, randomized, double-masked, sham-controlled, multicenter, phase 3 clinical trial with a 2-month open-label study extension. Patients with branch or central RVO received DEX (n = 129) or sham procedure (n = 130) in the study eye at baseline; all patients who met re-treatment criteria received DEX at month 6...

BACKGROUND: To evaluate the efficacy of bevacizumab on reduction of the enucleation rate and control of intraocular pressure (IOP) in neovascular glaucoma (NVG)-complicating proton beam therapy for UM and to identify the determinants of the efficacy of bevacizumab. METHODS: Retrospective comparative study of patients with rubeosis following proton therapy for uveal melanoma. Patients were divided into two groups: a bevacizumab group and a control group which comprised two subgroups: panretinal photocoagulation (PRP)/cryotherapy and observation subgroups...

PURPOSE: To identify preoperative factors associated with the surgical corrective effect of contralateral inferior rectus recession (IRR) for vertical deviation in patients with congenital superior oblique palsy (SOP). METHODS: This retrospective study included 20 treatment-naïve patients with unilateral congenital SOP (age range, 6-79 years) who underwent contralateral IRR according to our basic policy to select IRR for paretic eye fixation. The corrective effect (°/mm) of IRR was defined as the difference in the vertical deviation at the primary gaze position between before and 6-18 months after surgery per distance of recession...

PURPOSE: As accommodation is a dynamic process changing anterior ocular structures, we aim to compare the repeatability between the biometric measurements taken with and without accommodation. METHODS: Thirty healthy right eyes were measured in a baseline and an accommodative state using Visante-OCT. Three repeated measurements were taken to obtain central corneal thickness (CCT), anterior chamber depth (ACD), angle-to-angle distance (ATA), iridocorneal angles (IA), and crystalline lens thickness (LT)...

PURPOSE: To detect, using multimodal imaging, lacquer cracks (LCs) and myopic stretch lines (MSLs) in pathologic myopic eyes with macular hemorrhage (MHE) and those without. METHODS: We collected 18 consecutive pathologic myopic eyes (spherical equivalent ≤ -8.0 diopters) that had presented with linear, yellowish-white lesions in the macula. We categorized the eyes into either the MHE group or the non-MHE group. All underwent fluorescein angiography (FA), near infrared autofluorescence (NIA), indocyanine green angiography (ICGA), and spectral-domain optical coherence tomography (SD-OCT)...

PURPOSE: To evaluate functional and anatomical outcomes after aflibercept in patients with diabetic macular edema (DME) with poor response to bevacizumab. METHODS: We retrospectively reviewed patients with DME recalcitrant to bevacizumab who were switched to aflibercept between January and December 2015. All patients had a minimal follow-up of three months before the conversion and underwent at least three injections of bevacizumab. Functional outcome consisted in best corrected visual acuity (VA)...

PURPOSE: To study corneal innervation in eyes with history of herpetic keratitis and its correlation with corneal sensitivity and biomechanical properties. METHODS: A total of 56 eyes were included, of which 16 had a history of unilateral immune stromal herpetic keratitis, 16 were their contralateral eyes, and 20 were healthy controls. Structural analysis of corneal nerve plexus was performed by confocal microscopy. Biomechanical properties were measured with the Ocular Response Analyzer...

PURPOSE: Our purpose was to compare the impact in diabetic macula edema (DME) of two intravitreal drugs (0.5 mg ranibizumab vs. 8 mg triamcinolone) on changes in retinal morphology in spectral-domain optical coherence tomography (SD OCT) images, color fundus photography (CF) and fluorescein angiography (FA) images during a 1-year follow-up. METHODS: Post hoc analysis was conducted of morphologic characteristics in OCT, FA and CF images of eyes with a center involving DME that were included in a prospective double-masked randomized trial...

PURPOSE: To report the clinical (anatomic and functional) and genetic findings of Wagner Syndrome (WS) in a Portuguese family. METHODS: Nine members of the family agreed to be examined. All had complete clinical eye examinations. The proband and selected patients underwent color fundus photography, spectral domain optical coherence tomography (SD-OCT), automatic static white-on-white computerized perimetry, and electrophysiology assessment (flash ERG, multifocal(mf) ERG and dark adaptometry)...
