A computational account on the development of a preferred retinal locus.
Journal of Vision, 2015 A saccade brings a retinal locus to a target in the visual field. For normally sighted individuals, this retinal locus is the fovea. Central field loss (CFL) caused by macular degeneration often leads to the adoption of a preferred retinal locus (PRL) in

Reorganization of visual processing in macular degeneration is not specific to the "preferred retinal locus". [PDF]
J Neurosci, 2009 Recent work has shown that foveal cortex, deprived of its normal bottom-up input as a result of macular degeneration (MD), begins responding to stimuli presented to a peripheral retinal location. However, these studies have only presented stimuli to the “preferred retinal location,” or PRL, a spared part of the peripheral retina used by individuals ...

Transfer of an induced preferred retinal locus of fixation to everyday life visual tasks.
Journal of Vision, 2017 Subjects develop a preferred retinal locus of fixation (PRL) under simulation of central scotoma. If systematic relocations are applied to the stimulus position, PRLs manifest at a location in favor of the stimulus relocation.

Biofeedback Fixation Training in the Rehabilitation of Patients with Geographic Atrophy [PDF]
LifeGeographic atrophy (GA) is a progressive cause of central vision loss with limited rehabilitation options. This prospective case series aimed to evaluate the effects of biofeedback fixation training (BFT) on visual function and vision-related quality of ...

Analysis of blue light pixels for detection of preferred retinal locus
Ophthalmology Case Reports, 2017 Detection of ‘Preferred Retinal Locus’ (PRL) in human eyes is one of the important tests duringclinical assessment for treatment of certain retinal lesions. Significance of blue light has beenanalyzed in this paper using simple image processing algorithm

A Visual Telerehabilitation Program in Virtual Reality for Age-Related Macular Degeneration: Randomized Feasibility and Proof-of-Concept Trial [PDF]
JMIR Rehabilitation and Assistive TechnologiesBackgroundAge-related macular degeneration (AMD) causes progressive central vision loss in older adults. Low-vision rehabilitation can improve functional vision by training the use of a preferred retinal locus, commonly through clinic-based biofeedback ...

Visual function and biofeedback training of patients with central vision loss: a review [PDF]
International Journal of Ophthalmology, 2023 Older individuals with macular diseases, such as age-related macular degeneration, experience central vision loss (CVL) due to degeneration of their photoreceptors and retinal cells.
