An audio-visual motor training improves audio spatial localization skills in individuals with scotomas due to retinal degenerative diseases.

Several studies have shown that impairments in a sensory modality can induce perceptual deficits in tasks involving the remaining senses. For example, people with retinal degenerative diseases like Macular Degeneration (MD) and with central scotoma show biased auditory localization abilities towards the visual field's scotoma area. This result indicates an auditory spatial reorganization of cross-modal processing in people with scotoma when the visual information is impaired.

Audio-Visual Thumble (AVT): A low-vision rehabilitation device using multisensory feedbacks.

Since the 70s sensory substitution devices have been used for blind individuals to compensate for the lack of vision and enable them to perceive environment through intact sensory modalities. In this study, we present a rehabilitation device called Audio Visual Thumble (AVT), which is a small ring-like device with LED and buzzer, that can be worn on pharynx. We focus on a unique group of low-vision individuals with a black spot or scotoma in their visual field due to a disease called Macular Degeneration.

The Sound of Scotoma: Audio Space Representation Reorganization in Individuals With Macular Degeneration.

Blindness is an ideal condition to study the role of visual input on the development of spatial representation, as studies have shown how audio space representation reorganizes in blindness. However, how spatial reorganization works is still unclear. A limitation of the study on blindness is that it is a "stable" system and it does not allow for studying the mechanisms that subtend the progress of this reorganization.

Agreement in detecting glaucomatous visual field progression by using guided progression analysis ?and Humphrey overview printout.

Purpose: To examine the level of agreement among 3 clinicians in assessing glaucoma visual field progression by using 2 different methods.

Methods: Each visual field was assessed by Humphrey Field Analyzer (HFA), program SITA standard 30-2 or 24-2. In each printout the first 3 fields were excluded to minimize learning effect: the fourth and fifth full-threshold or SITA Standard examinations were used as baseline.

Sector-based analysis with the Heidelberg Retinal Tomograph 3 across disc sizes and glaucoma stages: a multicenter study.

Purpose: To investigate the ability of sectorial analysis using the Heidelberg Retinal Tomograph 3 (HRT3) to discriminate between healthy and glaucomatous eyes and to determine whether this is affected by disc size and glaucoma severity.

Design: Multicenter, cross-sectional evaluation of diagnostic tests.

Participants: Two hundred thirty-three eyes from 137 normal subjects and 96 glaucoma patients classified by the presence of a repeatable visual field defect.

Comparison between discriminant analysis models and "glaucoma probability score" for the detection of glaucomatous optic nerve head changes.

Purpose: The aim of this study was to evaluate and compare 4 different discriminant analysis formulas and the new Glaucoma Probability Score (GPS) for the detection of morphometric optic nerve head changes in chronic open-angle glaucoma.

Methods: This is a prospectively planned cross-sectional study. Two hundred and fourteen consecutive eyes were recruited into this study.

Exploring the Heidelberg Retinal Tomograph 3 diagnostic accuracy across disc sizes and glaucoma stages: a multicenter study.

Purpose: To investigate and compare the diagnostic accuracy of the Heidelberg Retinal Tomograph 3 (HRT3) diagnostic algorithms and establish whether they are affected by optic disc size and glaucoma severity.

Design: Multicenter cross-sectional evaluation of diagnostic tests.

Participants: Two hundred forty-two eyes from 139 normal subjects and 103 glaucomatous patients classified by the presence of a repeatable visual field (VF) defect.
