Vision rehabilitation workforce in Italy: a country-level analysis.

Background: Research and monitoring of human resources available for vision rehabilitation services has been a neglected area of work in the past. This study aims to offer an overview of the vision rehabilitation workforce available in Italy, in order to profile the distribution and number of human resources for vision rehabilitation.

Methods: Data on the available vision rehabilitation professionals were collected from the yearly report on the state of implementation of policies relating to the prevention of blindness, education and vision rehabilitation, according to a law which was passed by the Italian Ministry of Health, Department of Health Prevention.

Epidemiological Surveillance of Eye Disease and People Awareness in the Abruzzo Region, Italy.

: Vision impairments and related blindness are major public health problems. The prevalence of eye disease and barriers to optimal care markedly vary among different geographic areas. In the Abruzzo region (central Italy), an epidemiological surveillance on the state of ocular health in the population aged over 50 years was performed in 2019.

A New System for Assessing Visual Disability Using a Digital Visor.

Background: Considering the lack of universally accepted visual requirements for driving and for defining various grades of visual disability, the aim of this study is to propose a new method that provides a numerical score resulting from a combined assessment of the visual field and visual acuity loss obtained using a digital technology visor.

Methods: This study presents a new system for calculating the percentage of visual disability by combining binocular visual acuity and binocular visual field assessments. A new Global Vision Evaluation System digital technology visor uses standardized, reproducible criteria to produce well-defined, numerically expressed test results.

[Blindness and social security in Italy: critical issues and proposals.].

In Italy, blindness and low vision are ruled by Law 138/2001: two categories of blindness (corresponding to the one in the current WHO classification), receiving economical remuneration, and three categories of low vision, not directly remunerated. The problem ensues that low vision patients, who better gain from rehabilitation, have no economical contribution to undergo such care pathways; moreover, in Italy the evaluation has not yet shifted from "visual function" to "functional vision", thus lacking a holistic evaluation of visual dysfunction impact on the patient's daily life skills. To quantify the visual function of the examinee, only subjective performance (visual acuity and/or visual field) is evaluated in accordance with Law 138/2001, thus paving the way to malingerers: the "false blinds" phenomenon has recently reached the media.

Neurofibromatosis: an update of ophthalmic characteristics and applications of optical coherence tomography.

Neurofibromatosis (NF) is a multisystem disorder and tumor predisposition syndrome caused by genetic mutation on chromosome 17-17q11.2 in NF type 1 (NF1), and on chromosome 22-22q12.2 in NF type 2.

Spectral domain optical coherence tomography and B-scan ultrasonography in the evaluation of retinal tears in acute, incomplete posterior vitreous detachment.

Background: The purpose of this study was to evaluate the extension and traction effects of posterior vitreous detachment (PVD) complicated with retinal tears using spectral domain optical coherence tomography (OCT) and B-scan ultrasonography.

Methods: Complete ophthalmological examination, B-scan ultrasonography and spectral domain OCT were performed in patients with acute PVD and retinal tears. Vitreous detachment was classified as complete or incomplete, based on extent of posterior pole or peripheral vitreous detachment.

Ophthalmic Alterations in the Sturge-Weber Syndrome, Klippel-Trenaunay Syndrome, and the Phakomatosis Pigmentovascularis: An Independent Group of Conditions?

The phakomatoses have been traditionally defined as a group of hereditary diseases with variable expressivity characterized by multisystem tumors with possible malignant transformation. The Sturge-Weber syndrome, Klippel-Trenaunay syndrome, and the phakomatosis pigmentovascularis have the facial port-wine stain in common. Numerous pathophysiogenetic mechanisms have been suggested such as venous dysplasia of the emissary veins in the intracranial circulation, neural crest alterations leading to alterations of autonomic perivascular nerves, mutation of the GNAO gene in the Sturge-Weber syndrome, PIK3CA mutation in malformative/overgrowth syndromes such as the Klippel-Trenaunay syndrome, and the twin-spotting phenomenon in phakomatosis pigmentovascularis.

Choroidal Thickness Changes After Intravitreal Antivascular Endothelial Growth Factor Therapy for Age-Related Macular Degeneration: Ranibizumab Versus Aflibercept.

Purpose: To compare the changes in subfoveal choroidal thickness (CT) in eyes with neovascular age-related macular degeneration (nAMD) treated with intravitreal ranibizumab or aflibercept.

Methods: In this retrospective case series, the medical records of 28 patients with nAMD treated with at least 3 consecutive monthly injections of ranibizumab (0.5 mg/0.

Irritable eye syndrome: neuroimmune mechanisms and benefits of selected nutrients.

Previous studies showed comorbidity of some ocular, enteral, and affective symptoms comprising irritable eye syndrome. Aims of the present study were to learn more about the pathogenic mechanisms of this syndrome and to evaluate benefits of food supplements on these disorders. In in vitro assay, Lactobacillus acidophilus lysate inhibited interleukin (IL)-1β and tumor necrosis factor (TNF)-α generation of lipopolysaccharide (LPS)-stimulated macrophages in dose- and size-dependent manner.

Choroidal thinning as a new finding in Alzheimer's disease: evidence from enhanced depth imaging spectral domain optical coherence tomography.

Background: The involvement of retina and its vasculature has been recently described in Alzheimer's disease (AD). However, none of the previous works have yet investigated the choroid in vivo.

Objective: Spectral domain optical coherence tomography (SD-OCT) and enhanced depth imaging (EDI) technique is non-invasively used to assess choroidal thickness in patients with AD and to determine whether the peripapillary retinal nerve fiber layer (RNFL) and central retinal thickness are reduced compared to normal subjects.

Clinical and microperimetric predictors of reading speed in low vision patients: a structural equation modeling approach.

Purpose: To investigate the simultaneous association of several psychophysical measures with reading ability in patients with mild and moderate low vision attending rehabilitation services.

Methods: Standard measurements of reading ability (Minnesota Reading [MNREAD] charts), visual acuity (Early Treatment of Diabetic Retinopathy Study [ETDRS] charts), contrast sensitivity (Pelli-Robson charts), reading contrast threshold (Reading Explorer [REX] charts), retinal sensitivity, and fixation stability and localization (Micro Perimeter 1 [MP1] fundus perimetry) were obtained in 160 low vision patients with better eye visual acuity ranging from 0.3 to 1.

Relationship between fixation stability measured with MP-1 and reading performance.

Background: People with visual impairment have reduced reading performance, which is thought to be related to unstable or eccentric fixation. New microperimeters such as the MP-1 offer straightforward analysis of fixation stability. The aim of this study was to investigate the relationship between fixation stability and reading speed in a large cohort of people with diverse causes of visual impairment and to verify the correlation between reading speed and different methods for the quantification of fixation.
