“…In general, prior work has emphasized qualitative descriptions of the patterns of VF loss using topography and imaging. 5 , 11 , 18 The quantitative method that we developed may facilitate future research to better understand the influence of patient-, disease-, and environment-related factors on peripheral retinal function in RP. Further analysis of this dataset by detailed genotype characteristics was beyond the scope of the current work but may be useful to generate hypotheses regarding genetic determinants of the differences in pVF preservation.…”

“…The clinical diagnosis of RP was determined by an inherited retinal diseases specialist, based on a combination of all available clinical data including symptoms of nyctalopia or peripheral vision loss, mid-peripheral pigmentary retinopathy on biomicroscopy or imaging studies, visual field constriction, and scotopic full-field electroretinogram reduction that was greater than photopic reduction. GVFs, having been recorded according to the standard protocol, 7 , 11 were extracted as PDFs from the electronic case records. The cross-sectional dataset included the first (or only) GVF of that subject.…”

Purpose Retinitis pigmentosa (RP) is typified by progressive peripheral visual field (pVF) loss in patterns that can vary between individuals. Greater understanding of pVF preservation may inform research on therapeutic targets. However, characteristics of retained pVF are incompletely understood. We aimed to evaluate the spatial characteristics of retained pVF in RP. Methods We developed a computational platform to generate a probability map of the spatial distribution of retained pVF loci using the Goldmann V4e isopter. RP subjects were grouped into cross-sectional and longitudinal datasets. Probability maps of retained pVF were generated for categories of symptomatic disease duration (SDD). We applied a mathematical model to determine the anatomical correlate of the retained pVF. Results A total of 152 subjects were included. The mean age was 46.7 years. SDD was <20 years (47.4%), 20 to 40 years (39.5%), or >40 years (13.2%). Longitudinal data (3.2–5.7 years of follow up) were available for 65 subjects. In the cross-sectional dataset, retained pVF loci were most likely to be located between the 50° and 80° isoeccentric meridians and between the 30° to 50° radial axes. In the longitudinal dataset, inferotemporal pVF loci were the most likely to be preserved over time. The area of pVF retention corresponded anatomically to the pre-equatorial superonasal retina. Conclusions Semiautomated quantitation of pVF may be a useful tool to analyze spatial characteristics of VF in RP. Retinal cells in the superonasal periphery may be resilient to RP-related functional decline. Understanding the cellular and molecular basis of pVF resilience in the retina may inform efforts to develop treatment modalities for RP.

“…As such, solid angles are less sensitive to peripheral distortions than are area measures 18. The VF solid angles (in steradians, “sr”) in this study were derived by on-screen digitizing of the scanned OVFs and GVFs by using the FieldDigitize v4.0 program 18–20. All digitizing was performed by the same person.…”

Purpose To investigate the precision of visual fields (VFs) from semiautomated kinetic perimetry (SKP) on Octopus 900 perimeters, for children and adults with inherited retinal degenerations (IRDs). Goldmann manual kinetic perimetry has long been used in the diagnosis and follow-up of these patients, but SKP is becoming increasingly common. Octopus VFs (OVFs) and Goldmann VFs (GVFs) were both mapped on two occasions. Methods Nineteen females and 10 males with IRDs were tested on OVFs and GVFs, with two targets per test (V4e and one smaller target). Tests were performed in the same (randomized) order at two visits about 1 week apart. The VFs were digitized to derive isopter solid angles. Comparisons, within and between visits, were performed with paired t -tests and Bland-Altman plots. Results Median age was 20 years (range, 7–70; 10 participants aged ≤17 years old). There were no significant differences in solid angles between OVFs and GVFs ( P ≥ 0.06) or between the two visits' solid angles on either perimeter ( P ≥ 0.30). Between-visit test–retest variability for GVFs and OVFs was similar ( P ≥ 0.73), with median values of approximately 9% to 13%. Overall variability was lower for children than adults (medians of 7.5% and 12.8%, respectively). Conclusions Octopus SKP and Goldmann perimetry produced VFs of similar size and variability. Translational Relevance Our study indicates that SKP provides a viable alternative to traditional Goldmann perimetry in clinical trials or care involving both children and adults with IRDs.

“…Visual functions assessment was performed with a standard visual acuity test, Goldman kinetic perimetry, 40 and Goal Attainment Scale (GAS). 41 GAS is a sensitive individualized, criterion-referenced method measuring specific outcomes on individual goals after a period of treatment and widely used to supplement standardized measures of outcome that investigated, pre/post treatment and in follow-up, the modification of specific parameters; in our article, we have analyzed compliance with the treatment, visual acuity, visual field, and visual fixation.…”

Late recovery of consciousness in vegetative state is considered as an exceptional outcome and has been reported prevalently in patients who suffered a traumatic brain injury. In these patients, the benefits of prolonging the rehabilitation, aimed at the recovery of autonomy in basic everyday activities, has been demonstrated. Here, we describe the application of an intensive multi-professional rehabilitation program carried out on a young female patient, with exceptionally late recovery of consciousness, specifically, after 7 years of vegetative state due to severe brain hemorrhage. Neuropsychological and functional assessment was conducted before and after the end of the rehabilitation program. In addition, functional magnetic resonance imaging (fMRI) and diffusion tensor imaging (DTI)-based probabilistic tractography were performed. Two follow-up neuropsychological and functional assessments were also conducted 6 and 29 months after the conclusion of the program. Functional results showed an improvement, maintained over time, in walking with assistance, cognitive efficiency, visual acuity and visual field, dysarthria, and execution of activities of daily living. Moreover, functional and structural magnetic resonance imaging (MRI) data documented the existence of preserved neural networks involved in sensory, motor, and linguistic tasks, which in all likelihood support the recovery process. This report suggests the possibility of undertaking an intensive rehabilitation program in patients who remain for long periods in altered states of consciousness, in spite of early negative prognosis.
