PurposeThe purpose of this study is to evaluate an early switch to aflibecept in eyes with neovascular age-related macular degeneration (nvAMD) showing partial or lack of response for initial therapy with bevacizumab.MethodsThe Aflibercept as a Second Line Therapy for Neovascular Age Related Macular Degeneration in Israel (ASLI) was a prospective, multicenter, single-arm clinical trial. Eyes with nvAMD having incomplete response to 3-9 prior bevacizumab injections were recruited. Three monthly intravitreal aflibercept (2 mg) injections were administered, followed by two bi-monthly injections and a final examination at week 28...

METHODS: This study was conducted in the long-term care facility units at the Institut universitaire de gériatrie de Montréal. All residents ≥65 years old (y.o.), having a clinical diagnosis of dementia, and able to understand French or English, were eligible for participation in the study. All residents participating in the study received a complete eye exam by an experienced optometrist...

A 69-year-old man became aware of people's speech being out of synch with their lip movements alongside persistent headaches, both of which progressively worsened. A few weeks later, he developed progressive and painless visual loss in one eye. Initial neurological evaluation, inflammatory markers and head computed tomography scan were normal. Ophthalmological examination and OCT scan revealed right macular subretinal fluid with choroidal indentation, which prompted urgent further investigations including head MRI revealing extensive leptomeningeal disease...

Tumor necrosis factor alpha (TNFα)-induced angiogenesis plays important roles in the progression of various diseases, including cancer, wet age-related macular degeneration, and rheumatoid arthritis. However, the relevance and role of vascular cell adhesion molecule-1 (VCAM-1) in angiogenesis have not yet been clearly elucidated. In this study, VCAM-1 knockdown shows VCAM-1 involvement in TNFα-induced angiogenesis. Through competitive blocking experiments with VCAM-1 Ig-like domain 6 (VCAM-1-D6) protein, we identified VCAM-1-D6 as a key domain regulating TNFα-induced vascular tube formation...

RNA-guided genome surgery using CRISPR-Cas9 nucleases has shown promise for the treatment of diverse genetic diseases. Yet, the potential of such nucleases for therapeutic applications in nongenetic diseases is largely unexplored. Here, we focus on age-related macular degeneration (AMD), a leading cause of blindness in adults, which is associated with retinal overexpression of, rather than mutations in, the VEGFA gene. Subretinal injection of preassembled, Vegfa gene-specific Cas9 ribonucleoproteins (RNPs) into the adult mouse eye gave rise to mutagenesis at the target site in the retinal pigment epithelium...

PURPOSE: To describe detailed morphological and vascular features of the choroid in eyes with high myopia. DESIGN: Cross-sectional study. METHODS: 515 eyes of young men (mean age 21.59±1.15) years) with high myopia (defined as -6.0 D or worse, mean spherical equivalent -8.66±2.00 D) and 88 controls with emmetropia in both eyes underwent choroidal imaging using spectral domain optical coherence tomography with enhanced depth imaging (EDI-OCT)...

INTRODUCTION: Posterior Capsular Opacifications (PCO) is a frequent complication of cataract surgery following posterior chamber intraocular lens implantation. Nd -Yag laser capsulotomy is the treatment of choice for PCO and is known to be associated with complications like Raised Intraocular Pressure (IOP), Intraocular lens pitting, intraocular lens cracks, cystoid macular oedema, retinal detachment, corneal burns. Raised IOP is the most common complication and prescribing anti-glaucoma drugs post capsulotomy is a common practise...

Importance: Idiopathic macular holes (MHs) are a cause of decreased vision among older Americans. A better understanding of risk factors for MH may help clarify the pathophysiologic factors of MH and identify potential new avenues for preventing and treating idiopathic MHs.

Purpose: To quantify changes in visual function parameters and in the retinal nerve fiber layer and macular thickness over a 5-year period in patients with Parkinson's disease (PD). Methods: Thirty patients with PD and 30 healthy subjects underwent a complete ophthalmic evaluation, including assessment of visual acuity, contrast sensitivity vision, color vision, and retinal evaluation with spectral-domain optical coherence tomography (SD-OCT). All subjects were reevaluated after 5 years to quantify changes in visual function parameters, the retinal nerve fiber layer, and macular thickness...

PURPOSE: Anti-vascular endothelial growth factor therapy has improved the prognosis for patients with central retinal vein occlusion (CRVO). However, most studies published to date exclude ischemic CRVO. The purpose of this study was to describe the outcome in eyes with ischemic CRVO treated with anti-vascular endothelial growth factor therapy. METHODS: Thirty-seven patients with ischemic CRVO from 3 centers were followed for at least 6 months. Data on patient demographic, vision status, and anti-vascular endothelial growth factor treatments were collected...

PURPOSE: To evaluate the effects on postoperative prognosis of internal limiting membrane (ILM) peeling in conjunction with removal of idiopathic epiretinal membranes (ERMs). METHODS: MEDLINE, Cochrane Central Register of Controlled Trials (CENTRAL), and EMBASE were systematically searched for studies that compared ILM peeling with no ILM peeling in surgery to remove idiopathic ERM. Outcome measures were best-corrected visual acuity, central macular thickness, and ERM recurrence...

BACKGROUND: Cataract and age-related macular degeneration (AMD) are common causes of decreased vision that often occur simultaneously in people over age 50. Although cataract surgery is an effective treatment for cataract-induced visual loss, some clinicians suspect that such an intervention may increase the risk of worsening of underlying AMD and thus have deleterious effects on vision. OBJECTIVES: The objective of this review was to evaluate the effectiveness and safety of cataract surgery compared with no surgery in eyes with AMD...

We investigated retinal structure and function in eyes with optic nerve hypoplasia (ONH). Twenty-nine eyes of 18 patients with ONH and 21 eyes of 21 control patients were analyzed. Spectral-domain optical coherence tomography (SD-OCT), full-field electroretinography (FF-ERG), and focal macular ERG (FM-ERG) were performed. SD-OCT analysis of the macular region showed significant ganglion cells complex (GCC) thinning nasally and temporally (P < 0.05), but the thickness from the inner nuclear layer (INL) to the retinal pigment epithelium (RPE) became thinner only nasally (P < 0...

Purpose. To report unusual presentation of type 1A idiopathic macular telangiectasia (IMT). Methods. Two middle-aged women with bilateral IMT were examined. Results. Both patients presented with a gradual vision loss in both eyes. Fundus examination was unremarkable in one case and showed small macular telangiectasia in both eyes in the other case. Fluorescein angiography (FA) revealed early bilateral macular punctuated hyperfluorescence corresponding to the dilated capillaries in both cases. FA and fundus examination confirmed also the absence of vascular abnormalities in the middle or anterior fundus periphery in one case...

PURPOSE: We present an atypical case of submacular fluid leading to serous macular detachment. METHOD/PATIENT: A 69-year-old man was evaluated for metamorphopsia in the left eye. RESULTS: Best-corrected visual acuity was 20/25 in both eyes. He had undergone cataract surgeries in both eyes 12 years ago. The axial length was 25.93 mm (OD) and 24.12 mm (OS). Optical coherence tomography showed posterior staphylomas and subretinal fluid on the superior border of the staphylomas in both eyes; in the left eye, submacular fluid was noted extending up to the macula...

A case of choroidal rupture caused by airbag-associated blunt eye trauma and complicated with massive subretinal hemorrhage and vitreous hemorrhage that was successfully treated with intravitreal injection of expansile gas and bevacizumab is presented. A 53-year-old man suffered from loss of vision in his right eye due to blunt eye trauma by a safety airbag after a traffic accident. On initial examination, the patient had no light perception in his right eye. Dilated ophthalmoscopy revealed massive subretinal hemorrhage with macular invasion and faint vitreous hemorrhage...
