Preferred retinal locus profile during prolonged fixation attempts
Canadian Journal of Ophthalmology, 2013The retinal area or location used during any fixation attempt defines the preferred retinal locus (PRL). It is presumed that during prolonged fixation attempts there may be various representative reference points within the PRL area. This study aims to clarify this presumption.Prospective, nonrandomized, observational case series.Sixty-five eyes of 41 ...

Preferred Retinal Locus Development in Patients with Macular Disease
Ophthalmology, 2005To observe the development of the preferred retinal locus (PRL) in a group of patients with central scotomas caused by recent onset macular disease (MD).Prospective observational case series.Twenty-five individuals with bilateral central scotomas caused by MD.

THE PREFERRED RETINAL LOCUS IN MACULAR DISEASE
Retina, 2011Eccentric viewing in macular disease has been described for half a century. However, a clear definition of eccentric viewing and preferred retinal locus (PRL) does not exist. Here, we determine how the PRL in macular disease is defined by researchers active in this field and, based on the responses received, propose a standardized definition of the ...

Benefit of Adaptive Optics Aberration Correction at Preferred Retinal Locus
Optometry and Vision Science, 2012 ABSTRACT Purpose. To investigate the effect of eccentric refractive correction and full aberration correction on both high‐ and low‐contrast grating resolution at the preferred retinal locus (PRL) of a single low‐vision subject with a long‐standing central scotoma.

simple and new technique for detection of ‘Preferred Retinal Locus’ (PRL) in human eye is proposed in this paper. Simple MATLAB algorithms for estimating RGB pixel intensity values of retinal images were used. The technique proved non-existence of ‘S’ cones in Fovea Centralis and also proposes that rods are involved in blue color perception. Retinal

ABSTRACT: Purpose: It is difficult to determine the position of a preferred retinal locus (PRL) relative to the fovea in scanning laser ophthalmoscope (SLO) images as a result of disease‐related retinal morphologic changes that obscure the fovea.
