Abstract
BACKGROUND The Bartimeus training program (BT) is a perceptual learning task that consists of a drawing assignment performed in 12 sessions of 30 minutes duration. Here we aim to retrospectively assess visual improvement in children who underwent BT and in whom visual acuity had not improved by glasses or patching in relation to patient age and diagnosis. MATERIAL AND METHODS Retrospective chart analysis of patients who had undergone BT at our institution after consent. Visual acuity prior to and following BT was analyzed, as were diagnosis and age at BT. RESULTS Thirteen patients (20 eyes) with a mean age of 7 years (range: 3.9 - 10.75) were included. Overall acuity (LogMar) improved in 75%. Six patients aged 6.5 - 7.5 years had a mean improvement of 1.4 lines. The greatest improvement (5 lines crowding acuity) was seen in a 9-year-old with recent onset amblyopia due to corneal scarring. Two patients aged 6 years with deprivation amblyopia following surgery of a congenital cataract and one 5-year-old with retinitis pigmentosa did not benefit from BT. CONCLUSIONS BT is a cheap noninvasive method that may help improve visual outcomes. Further studies with larger numbers are needed to assess optimal indication, timing, and length of treatment.

Fonteyn-Vinke A, Huurneman B, Boonstra FN. Viewing Strategies in Children With Visual Impairment and Children With Normal Vision: A Systematic Scoping Review. Front Psychol 2022; 13:898719. [PMID: 35783772 PMCID: PMC9248372 DOI: 10.3389/fpsyg.2022.898719] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/17/2022] [Accepted: 05/19/2022] [Indexed: 11/25/2022] Open
Abstract
Viewing strategies are strategies used to support visual information processing. These strategies may differ between children with cerebral visual impairment (CVI), children with ocular visual impairment, and children with normal vision since visual impairment might have an impact on viewing behavior. In current visual rehabilitation practice a variety of strategies is used without consideration of the differences in etiology of the visual impairment or in the spontaneous viewing strategies used. This systematic scoping review focuses on viewing strategies used during near school-based tasks like reading and on possible interventions aimed at viewing strategies. The goal is threefold: (1) creating a clear concept of viewing strategies, (2) mapping differences in viewing strategies between children with ocular visual impairment, children with CVI and children with normal vision, and (3) identifying interventions that can improve visual processing by targeting viewing strategies. Four databases were used to conduct the literature search: PubMed, Embase, PsycINFO and Cochrane. Seven hundred and ninety-nine articles were screened by two independent reviewers using PRISMA reporting guidelines of which 30 were included for qualitative analysis. Only five studies explicitly mentioned strategies used during visual processing, namely gaze strategies, reading strategies and search strategies. We define a viewing strategy as a conscious and systematic way of viewing during task performance. The results of this review are integrated with different attention network systems, which provide direction on how to design future interventions targeting the use of viewing strategies to improve different aspects of visual processing.

J Clin Med 2022; 11:jcm11071879. [PMID: 35407483 PMCID: PMC8999262 DOI: 10.3390/jcm11071879] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/21/2022] [Revised: 03/05/2022] [Accepted: 03/22/2022] [Indexed: 02/01/2023] Open
Abstract
Limbal dermoid (LD) is a congenital ocular tumor that causes amblyopia and damages visual acuity (VA) and visual function. This study evaluated the therapeutic efficacy of perceptual learning (PL) toward improving contrast sensitivity function (CSF) and VA. A total of 25 children with LD and 25 normal children were compared in terms of CSF and VA. The LD group was further randomly allocated into two arms: nine underwent PL combined with patching and eight underwent patching only; eight patients quit the amblyopia treatment. The primary outcome was the area under log CSF (AULCSF), and the secondary outcome was the best corrected VA (BCVA). The CSF was obviously reduced in the LD group compared with that in the normal group. Moreover, the difference in the changes in the AULCSF between the PL and patching groups after 6 months of training was 0.59 (95% CI: 0.32, 0.86, p < 0.001), and the between-group difference in VA at 6 months was −0.30 (95% CI: −0.46, −0.14, p < 0.001). Children suffering from LD with amblyopia exhibited CSF deficits and VA loss simultaneously. PL could improve CSF and VA in the amblyopic eye better than patching.

Abstract
This pilot study investigated the effects of a visual training program for students with low vision. A pre and post design was used. The Beery-Buktenica Developmental Test of Visual-Motor Integration and the Test of Visual-Perceptual Skills were used to assess the perceptual and visual motor skills of fifteen students with low vision. Their mean age was (8.47 ± 1.12); and the mean of their visual acuity of was (0.12 ± 0.11). The three-part intervention program (physical worksheets, a computer-based intervention program, activities of visual perceptual skills) was implemented over four weeks (three sessions/week). Kruskal Wallis tests were used to examine the effect of visual acuity on the progress achieved, and the Wilcoxon-Signed Ranks test was used to identify differences in the scores pre-post intervention. Results showed statistically significant improvement in the visual perceptual and visual-motor integration skills. There was not any statistically significant effect of visual acuity on the progress achieved.

Abstract
Current treatments for infantile nystagmus (IN), focused on dampening the oscillating eye movements, yield little to no improvement in visual functioning. It makes sense, however, to treat the visual impairments associated with IN with tailored sensory training. Recently, we developed such a training, targeting visual crowding as an important bottleneck in visual functioning with an eye-movement engaging letter discrimination task. This training improved visual performance of children with IN, but most children had not reached plateau performance after 10 supervised training sessions (3,500 trials). Here, we evaluate the effects of prolonged perceptual learning (14,000 trials) in 7-18-year-old children with IN and test the feasibility of tablet-based, at-home intervention. Results demonstrate that prolonged home-based perceptual training results in stable, long lasting visual acuity improvements at distance and near, with remarkably good transfer to reading and even stereopsis. Improvements on self-reported functional vision scores underline the clinical relevance of perceptual learning with e-health apps for individuals with IN.
