Summary: This study aimed to assess the occurrence and clustering of post-concussive symptoms in children and identify distinct patient phenotypes based on symptom type and severity. The results showed that post-concussive symptoms occur in distinct clusters and five patient groups were identified based on symptom type and severity.

Summary: This study evaluates the applicability of the International Reading Speed Texts (IReST) in a normal Canadian population. The results show that our cohort read slower compared to the IReST standards. Additionally, reading speed decreases with age. The use of British English in the test materials may also contribute to the lower reading speed. Therefore, it is important to evaluate IReST in different populations to ensure reliable comparison standards for future research.

Summary: Cognitive impairment and post-concussive symptoms are common sequelae of pediatric mild traumatic brain injury. This study compared the cognitive outcomes of asymptomatic and symptomatic pmTBI patients with healthy controls during the sub-acute and early chronic phases. The results showed that symptomatic patients performed worse than healthy controls in processing speed, attention, and verbal memory during the sub-acute phase, while both groups showed lower performance in verbal memory during the early chronic phase. The findings suggest that cognitive recovery may be a separate process from the resolution of subjective symptomology.

Summary: This study aimed to characterize the clusters of prolonged post-concussive symptoms lasting more than 12 months and investigate their association with functional impairments. Through testing 445 individuals with prolonged symptoms, five main symptom-clusters were identified, and some of these clusters were found to be associated with functional deficits.

Summary: The study validated that older Canadian adults (60+) read the IReST texts significantly slower than the standardized values, suggesting that clinicians and researchers should be aware of age-related differences when using the IReST for assessing reading speed in older adults.

Summary: The study found that patients with cyclodeviation had significantly lower health-related quality of life scores compared to controls. Postoperative functional scores significantly improved, but psychosocial scores did not show significant improvement.

Summary: Patients with mild traumatic brain injuries (mTBI) display impairments in fine motor skills, visuomotor integration, and form recognition, along with deficits in visuospatial attention. However, motion perception and critical flicker fusion are not affected. The impairment in visuo-motor coordination is associated with speed in visuo-attention and correlates with symptoms severity.

Summary: The literature shows asynchronous developmental trajectories of global motion and global form perception, with global motion perception maturing faster. The oblique effect is present at 4 years of age. General cognitive ability and basic visual functions are closely related to the development of motion and form perception.

Summary: This study reviewed and evaluated the long-term surgical outcomes of the Fells-modified Harada-Ito procedure in patients with torsional diplopia. The use of individual dose scales during surgery and post-operative evaluations corresponded with the aimed-for correction of torsional diplopia.

Summary: The authors demonstrate the existence of a visuo-vestibular network from lamprey to primates, which is essential for gaze stabilization. This network highlights the organization of visual and vestibular streams in controlling eye movements. Through the vestibulo-ocular and optokinetic reflexes, multisensory information stabilizes the scene on the retina. It is also found that all basic components of visuo-vestibular control of gaze are present in lampreys.

Summary: This study evaluated the correlation between BCVA before treatment and clinicopathological factors and patient survival in uveal melanoma. The results showed that UM patients with low BCVA before treatment had larger tumor size and worse prognosis.

Summary: The purpose of this study was to construct and validate a Swedish translation (VVAS-S) of the Visual Vertigo Analogue Scale (VVAS). The translation process involved two authors translating the original English version into Swedish, which was then back-translated by an independent professional translator. The translated version was found to be comparable to the original in terms of internal reliability and was perceived as easy to implement by participants, making it suitable for clinical use in a Swedish-speaking setting.

Summary: The study aimed to identify biomarkers for visually induced dizziness (VID) through gaze-stabilizing eye movements. The results showed that VID patients had increased vergence and torsional velocities, indicating an increased oculomotor gain to visual motion, and the responses correlated with symptom severity. Coherent stimulation produced the fastest torsional slow-phases, and when faced with conflicting directional information, eye movements tended to follow the direction of the central visual field. In conclusion, post-concussion VID was associated with faster slow-phases during optokinetic gaze-stabilization, and both vergence and torsion were correlated to symptom intensity. Vertical vergence may be particularly useful for clinical applications.

Summary: This qualitative systematic review provides an overview of research on visual motion hypersensitivity (VMH) and serves as a reference for future studies. The study aims to identify and gather articles investigating risk groups with abnormal responses to visual motion and presents evidence of associated risk factors. Data were synthesized and analyzed in the context of each risk factor's clinical characteristics.
