OBJECTIVE
To describe and interpret the frequently observed spectral-domain optical coherence tomography (SD-OCT) finding of a marked hyporeflective wedge-shaped structure at the boundaries of the areas of atrophy.
METHODS
A prospective, longitudinal follow-up study.
METHODS
Consecutive patients (n
OBJECTIVE
To describe the occurrence of geographic atrophy in patients with retinal angiomatous proliferation (RAP).
METHODS
Demographics, visual acuity, color fundus photographs, fluorescein and indocyanine green angiograms, and fundus autofluorescence and near-infrared autofluorescence images were
OBJECTIVE
To report the presence of pseudocysts in retinal layers of eyes with geographic atrophy (GA) attributable to age-related macular degeneration (AMD) and to estimate their prevalence.
METHODS
Retrospective study.
METHODS
setting: Clinical practice. patients: Consecutive patients with GA,
I used the laser interferometer to test 137 eyes to determine whether preoperative interference visual acuity tests could accurately predict postoperative Snellen visual acuities. In 60 patients with immature cataracts and normal maculas the postoperative Snellen visual acuity was predictable within
OCT (opitcal coherence tomography), is a diagnostic method that enables the analysis of the retinal structures by means of high-resolution tomographic cross-sections of the retina. Whereas fluorescein and indocyanine angiography allow visualization of the retinal epithelium layer and chorioretinal
OBJECTIVE
To describe a method of en face visualization and quantification of the photoreceptor inner segment/outer segment junction area, using spectral-domain optical coherence tomography, and association with visual acuity.
METHODS
Case series of 74 eyes in 53 patients. Central 1-mm and 400-μm en
OBJECTIVE
To evaluate the safety and efficacy of an implantable visual prosthetic device (IMT; VisionCare Ophthalmic Technologies, Saratoga, CA) in patients with bilateral, end-stage age-related macular degeneration (AMD).
METHODS
Prospective, open-label, multicenter clinical trial with fellow eye
OBJECTIVE
To delineate pathologic changes in retinal cross sections obtained with spectral (Fourier) domain optical coherence tomography (SDOCT), so that the findings are maintained when collapsed into a two-dimensional fundus image for comparison with conventional retinal studies.
METHODS
SDOCT of
BACKGROUND
The combination of verteporfin photodynamic therapy (PDT) and anti-angiogenics has been shown to be safe and efficacious in the treatment of choroidal neovascularization (CNV) secondary to age-related macular degeneration (AMD). The purpose of this study is to demonstrate long-term
EPIDEMIOLOGICAL AND PATHOGENIC DATA: Age-related macular degeneration (ARMD) is the first cause of blindness in industrialized countries in patients over the age of 55. Its prevalence increases with age, affecting up to 25% of the population aged over 75. The pathogenesis of this disease is not well
OBJECTIVE
To describe and evaluate the performance of an algorithm that automatically classifies images with pathologic features commonly found in diabetic retinopathy (DR) and age-related macular degeneration (AMD).
METHODS
Retinal digital photographs (N = 2247) of three fields of view (FOV) were
Age-related macular degeneration (AMD) causes a progressive loss of photoreceptors in the macula. It is the most common cause of legal blindness in the United States, and some form of AMD is thought to affect more than 9 million individuals. Risk factors include older age, smoking, dyslipidemia,
Age-related macular degeneration (AMD) is the most common cause of blindness among people over age 55 years in industrialized countries. Known major risk factors for AMD include: age >55 years, history of smoking, white race, and mutations in various components of the complement system. Early AMD is
Diagnosis and treatment guidance are aided by detecting relevant biomarkers in medical images. Although supervised deep learning can perform accurate segmentation of pathological areas, it is limited by requiring a-priori definitions of these regions, large-scale annotations, and a representative
Bevacizumab (Avastin) is a recombinant humanized monoclonal immunoglobulin antibody that has two antigen-binding domains and blocks all active forms of vascular endothelial growth factor-A. It was originally designed and is still in use as antitumor agent (for colorectal and non-small cell lung
