Role of Visual Field Reliability Indices in Ruling Out Glaucoma

from ArchOpht - 01 Jan 15

ImportanceStandard automated perimetry is the current criterion standard for assessment of visual field (VF) loss in glaucoma. The 3 commonly used reliability indices to judge the quality of standard automated perimetry results are fixation losses (FLs) and false-positive (FP) and false-negative (FN) response rates. However, the influence of reliability indices, when within the manufacturer-recommended limits, on VF classification has been sparsely studied.ObjectiveTo evaluate the role of VF rel

Retinal Vascular Layers Imaged by Fluorescein Angiography and Optical Coherence Tomography Angiography

from ArchOpht - 01 Jan 15

ImportanceThe retinal vasculature is involved in many ocular diseases that cause visual loss. Although fluorescein angiography is the criterion standard for evaluating the retina vasculature, it has risks of adverse effects and known defects in imaging all the layers of the retinal vasculature. Optical coherence tomography (OCT) angiography can image vessels based on flow characteristics and may provide improved information.ObjectiveTo investigate the ability of OCT angiography to image the vasc

Risk of Musculoskeletal Injuries, Fractures, and Falls in Medicare Beneficiaries With Disorders of Binocular Vision

from ArchOpht - 01 Jan 15

ImportanceDisorders of binocular vision are increasingly prevalent among fee-for-service Medicare beneficiaries 65 years or older. Visual impairment is a recognized risk factor for fractures. Despite the association of visual impairment and fracture risk, to our knowledge, no study has examined the influence that disorders of binocular vision (strabismus, amblyopia, diplopia, and nystagmus) may have on musculoskeletal injury and fracture risk in the elderly population.ObjectiveTo evaluate associ

Retinal Vascular Layers in Macular Telangiectasia Type 2 Imaged by Optical Coherence Tomographic Angiography

from ArchOpht - 01 Jan 15

ImportanceMacular telangiectasia type 2 (MacTel 2) is a rare disease in which abnormalities of the retinal vasculature play a key role. The vascular abnormalities are typically evaluated using fluorescein angiography, a modality with known defects in imaging the deeper layers of the retinal vasculature. Angiography based on optical coherence tomography can image vessels based on flow characteristics without dye injection and may provide improved information concerning the pathophysiology of MacT

Intravitreal Triamcinolone–Illuminated Cataract Surgery for Patients With Dense Vitreous Hemorrhage

from ArchOpht - 01 Jan 15

Almost all cataract surgical procedures rely on phacoemulsification, which requires favorable lens visibility. Visibility can be negatively affected by various ocular pathologies including dense vitreous hemorrhage. When the microscope light source reflects off the ocular fundus, the lens is transilluminated. In the presence of dense vitreous hemorrhage, light cannot adequately reach the fundus, and no red reflex is created. In these patients, vitrectomy and cataract surgery may be performed sim
