“…Peripheral neuropathy and plantar extensor hyperreactivity patients can use ankle–foot orthosis, strengthen foot care and undergo regular review (Bouchard & Langlois, 1999). Furthermore, ophthalmological consultations and prism glasses may be effective in patients with abnormal eye findings (Lee et al, 2015).…”

Spinocerebellar ataxias, also called autosomal dominant cerebellar ataxias, are a group of neurological genetic diseases characterised by chronic, progressive cerebellar ataxia. The clinical hallmark of spinocerebellar ataxia is the loss of balance and coordination, accompanied by slurred speech. Spinocerebellar ataxia type 11 is a rare subtype of spinocerebellar ataxia caused by mutations in the tau tubulin kinase 2 gene. Patients with spinocerebellar ataxia are clinically characterised by slowly progressive cerebellar ataxia, trunk and limb ataxia, and eye movement abnormalities with occasional pyramidal features. Peripheral neuropathy and dystonia are rare. According to the literature, only nine families affected with spinocerebellar ataxia have been reported worldwide. Herein, a series of spinocerebellar ataxia cases are discussed in detail to determine the potential research direction of this dysfunction, including its epidemiology, clinical features, genetic characteristics, diagnosis and differential diagnosis, pathogenic mechanisms, treatment, prognosis, follow-up, genetic counselling and future perspectives, and to improve the overall understanding of spinocerebellar ataxia among clinicians, researchers and patients.

Zusammenfassung Hintergrund Das therapeutische Management von Motilitätseinschränkungen und begleitender Kopfzwangshaltung (KZH) stellt oft eine Herausforderung dar. Wir berichten über unsere Erfahrungen mit der Prismenapplikation. Patienten und Methoden Retrospektive Fallserie von 3 Patienten mit Augenmotilitätsstörungen und begleitender KZH, bei denen eine Behandlung mittels Prismenkorrektur erfolgte. Ergebnisse Ein 37-jähriger Mann mit traumatischer Okulomotoriusparese links mit leichter residueller Senkungseinschränkung und deutlicher Hebungseinschränkung zeigte nach Prismenausgleich der Hypotropie links (OS: 10^ Basis oben) ein Feld binokularen Einfachsehens (BES-Feld) nur im Abblick. Erst unter zusätzlicher Vorgabe von beidseits 10^ Basis oben gelang eine Verlagerung des BES-Feldes in die Primärposition. Ein 45-jähriger Mann mit Parinaud-Syndrom infolge eines Schädel-Hirn-Traumas und beidseitiger Hebungseinschränkung beklagte erhebliche Nackenbeschwerden bei ausgeprägter Kinnhebung. Zudem bestand bei Amaurose rechts eine sekundäre Exotropie. Unter Vorgabe von OS: 8^ Basis oben war der Patient bei Aufgabe der KZH auch subjektiv beschwerdefrei. Bei einer 69-jährigen Frau mit Abduzensparese links bestand eine Kompensation der Schielabweichung nur im äußersten Rechtsblick unter Einnahme einer ausgeprägten Linksdrehung von 20°. Mit OS: 20^ Basis temporal resultierte Doppelbildfreiheit ohne KZH in Primärposition. Schlussfolgerung Neben der Schielkorrektur kann auch die Blickverlagerung durch Prismen in verschiedenen klinischen Konstellationen therapeutisch hilfreich sein. Zur Reduktion der KZH erfolgt die prismeninduzierte Blickverlagerung prinzipiell in Richtung des Motilitätsdefizits.

The Effect of Vertically Yoked Prisms on Binocular Vision and Accommodation

et al. 2019

SIGNIFICANCE Vertically yoked prisms have been used in treatment of binocular vision dysfunction despite minimal supporting evidence. In people with normal binocular vision, the impact on phorias has been assessed but not the impact on accommodation, accommodation vergence interactions, or the horopter. We found that vertically yoked prisms have minor effects during short-term wear in young adults. PURPOSE The purpose of this study was to determine effects of vertically yoked prisms on accommodative response and several binocular vision tasks. METHODS There were 45 participants aged 18 to 24 years. The 23 myopes wore distance-corrected soft contact lenses. In a random arrangement, each person wore spectacles containing planopower lenses with either 8 Δ base-up, 4 Δ base-up, zero, 4 Δ base-down, and 8 Δ base-down prisms. Before spectacle wear, baseline measurements of near heterophoria, accommodation response, negative and positive relative accommodations, fusional vergence, and Nonius-horopter spatial perception were taken. Measurements were repeated after a 40-minute wear, spectacles were removed, and tests were performed 20 minutes later. On a 22-participant subset, on a separate occasion, measurements of heterophoria, accommodation response, and relative accommodation were made immediately after spectacles were fitted. RESULTS Most changes relative to baseline were not significant. Where effects occurred, these were nearly all associated with prism presence rather than adaptation. There were significant effects on accommodation response, but these seem to be refraction effects produced by pantoscopic tilt–induced power changes rather than perceptual effects altering accommodation. There were statistically significant effects on negative relative accommodation (P < .01), with zero prism giving more negative relative accommodation than 8 Δ base-down prisms. Tendencies were noted for prisms to move horopter limits toward the observer. Effects were small and likely not of clinical relevance. CONCLUSIONS Vertically yoked prisms have minor effects on accommodation and binocular vision, at least during short-term wear in young adults with normal binocular vision.
