A 5-year longitudinal study of macular atrophy

Macular atrophy (MA) is one of the late stages of age-related macular degeneration (AMD) and leads to irreversible loss of visual function. During the past years, efforts have been made towards a more detailed comprehension of the characteristics of MA, and a panel of retina specialists has recently established a new classification system to describe atrophy in the context of neovascular AMD, by the CONAN group...

Molecular and Multimodal Retinal Imaging Findings in a Multicentric Portuguese ...

Introduction Our purpose was to describe the molecular and multimodal retinal imaging findings in a cohort of Portuguese patients with a clinical diagnosis of Stargardt Disease (STGD1).   Methods Multicenter, cross sectional cohort study of consecutive patients with a clinical diagnosis of STGD1, referred from six Portuguese centers. All patients underwent a complete ophthalmological examination complemented by...

Central Serous Chorioretinopathy: Long-Term Results After Photodynamic Therapy

Introduction: Central serous chorioretinopathy (CSC) is an idiopathic syndrome characterized by neurosensory detachments of the retina. Development of chronic CSC is an indication to treat, and ICGA-guided verteporfin photodynamic therapy has been shown to be very effective.   Our objective was to evaluate the 13-year follow-up of chronic CSC patients treated with standard-fluence PDT and to explore the long-te...

Anterior Segment Optical Coherence Tomography in the Early Management of Microb...

Infectious keratitis is an important cause of visual loss. The purpose of this study was to investigate anterior segment optical coherence tomography patterns in infectious keratitis and evaluate the role of this tool in the early management of this disorder. Material and Methods: In this cross-sectional study, we included patients with proven infectious keratitis, either by culture or therapeutic trial. Subjec...

Peripapillary and macular morpho-vascular changes in patients with genetic or c...

Purpose: To evaluate the macular and peripapillary morpho-vascular changes in ADOA, using optical coherence tomography (OCT) and OCT angiography (OCTA). Methods: Prospectively defined, cross-sectional case-control study. Consecutive patients with a genetic or clinical diagnosis of ADOA along with age- and sex-matched controls were included. The radial peripapillary capillary (RPC) density and vessel density (VD...

Macular OCT-angiography parameters to predict the clinical stage of nonprolifer...

Background: To test whether a single or a composite set of macular vascular density parameters, evaluated with optical coherence tomography angiography (OCTA), are able to predict nonproliferative diabetic retinopathy (NPDR) staging according to the gold-standard ETDRS-grading scheme. Methods: Prospectively defined, cross-sectional study in which macular structural and vascular parameters of diabetic eyes with ...

Peripapillary neurovascular coupling in the early stages of diabetic retinopathy

Purpose: To study radial peripapillary capillary (RPC) density in the early stages of diabetic retinopathy (DR), using optical coherence tomography angiography. Methods: A cross-sectional evaluation of RPCs was performed using optical coherence tomography angiography (Avanti RTVue-XR 100, Optovue Inc, Fremont, CA). Annular RPC density was the primary outcome. Global density and retinal nerve fiber layer thickne...
