Introduction: Specific Learning Disorders (SLDs) have gained increasing clinical relevance due to the growing recognition of their impact in the context of changing visual and cultural demands. These disorders most commonly manifest as impairments in reading and writing, which may be associated with visual and oculomotor dysfunctions. In recent years, orthoptic assessment protocols have been refined to better identify visuoperceptual and visuomotor alterations, thereby enabling the detection of potential visuoperceptual deficits underlying learning disorders. Purpose: The present study describes the orthoptic management of an individual diagnosed with SLD, outlining the assessment of visuomotor and visuoperceptual functions. Particular focus is given to the administration of the Visual Perception Test (VPT) and its comparison with the results from a neurotypical control subject, with the goal of identifying the subtest most relevant for differential diagnosis. Materials and Methods: The subject underwent a comprehensive ophthalmologic examination and orthoptic evaluation. The assessment included ocular deviation measurement, visual acuity testing, evaluation of extrinsic ocular motility, analysis of saccadic movement quality, convergence testing, stereopsis evaluation, determination of motor and sensory dominance and visual perception was assessed with the VPT. Following completion of the visual rehabilitation program, the orthoptic assessment was repeated to monitor functional progress and rehabilitation outcomes. Results Discussion and Conclusions
Introduzione: I Disturbi Specifici dell'Apprendimento (DSA) rappresentano una problematica di crescente interesse clinico grazie all’attenzione che ad oggi le viene data, per il progressivo cambiamento avvenuto a causa delle diverse esigenze visive e culturali. Le difficoltà riscontrate maggiormente si riflettono nella lettura e nella scrittura che possono essere associate a disfunzioni visive e oculomotorie. In questi pazienti nel corso degli anni sono stati perfezionati diversi protocolli ortottici di valutazione in grado di far emergere alterazioni visuo-percettive e visuo-motorie per individuare i deficit visuo-percettivi che possono essere presenti nel disturbo d’apprendimento. Scopo: Illustrare la presa in carico di un paziente affetto da DSA, presentandone il percorso ortottico con la seguente valutazione specifica che esamina le alterazioni visuo-motorie e visuo-percettive, in particolare proponendo il Test di Percezione Visiva (TPV) per poi poter confrontare con un normo paziente quale subtest risulti fondamentale per fare diagnosi differenziale. Materiali e Metodi: Il paziente in esame è stato sottoposto a visita oculistica e valutazione ortottica con l’obiettivo di rilevare eventuali deviazioni oculari, acuità visiva, motilità oculare estrinseca, qualità dei movimenti saccadici, convergenza, stereopsi, dominanza motoria e sensoriale e la percezione visiva con l’ausilio del TPV. Al termine del percorso di riabilitazione visiva, la valutazione ortottica è stata ripetuta per monitorare i progressi ottenuti. Risultati Conclusioni
"Percezione visiva ed integrazione visuo-motoria nella valutazione della dislessia evolutiva".

Abstract
Introduction: Specific Learning Disorders (SLDs) have gained increasing clinical relevance due to the growing recognition of their impact in the context of changing visual and cultural demands. These disorders most commonly manifest as impairments in reading and writing, which may be associated with visual and oculomotor dysfunctions. In recent years, orthoptic assessment protocols have been refined to better identify visuoperceptual and visuomotor alterations, thereby enabling the detection of potential visuoperceptual deficits underlying learning disorders. Purpose: The present study describes the orthoptic management of an individual diagnosed with SLD, outlining the assessment of visuomotor and visuoperceptual functions. Particular focus is given to the administration of the Visual Perception Test (VPT) and its comparison with the results from a neurotypical control subject, with the goal of identifying the subtest most relevant for differential diagnosis. Materials and Methods: The subject underwent a comprehensive ophthalmologic examination and orthoptic evaluation. The assessment included ocular deviation measurement, visual acuity testing, evaluation of extrinsic ocular motility, analysis of saccadic movement quality, convergence testing, stereopsis evaluation, determination of motor and sensory dominance and visual perception was assessed with the VPT.
