Rationale and objectives: Parkinson’s disease (PD) significantly affects visual function, especially convergence and eye movements, impacting tasks such as reading. The objective was to investigate preliminarily the impact of the use of digital visual training in PD patients with associated convergence insufficiency (CI). Materials and methods: Pre–post pseudo-experimental pilot study to evaluate the impact of a novel digital therapy system (video game for use on a mobile phone or tablet) in 13 patients with PD and CI, with a mean age of 67 years. A comprehensive visual assessment was performed before and after a 6-week home-based visual rehabilitation, including measurement of near point of convergence (NPC), near positive fusional vergence (PFV), oculomotor tests (NSUCO and King-Devick tests), and symptom assessments with two validated questionnaires (CISS and SQVD). Results: Treatment adherence was variable, ranging from 0.8% to 124.7%. Despite this, significant improvements were found after therapy in break (p = 0.022) and recovery points of the NPC (p = 0.007), as well as break (p = 0.003) and recovery points in near PFV (p < 0.001). In the NSUCO test, the total score improved significantly from 23.9 ± 4.2 to 26.2 ± 3.7 after therapy (p = 0.003). Furthermore, a significant reduction in the total King-Devick test time was observed, decreasing from 79.4 ± 28.8 s to 69.0 ± 21.5 s with therapy (p = 0.034). Finally, symptom questionnaire scores also decreased significantly with therapy (CISS p = 0.037, SQVD p < 0.001). Conclusions: The digital vision therapy system evaluated seems to improve oculomotor control and reduce visual symptoms associated with CI in PD patients. Studies with larger sample sizes and a control group are needed to fully validate the therapeutic effectiveness of this tool.

Background/Objectives: We aim to characterize, through a survey-based approach conducted in Spain, the perspectives of healthcare professionals (HCPs) and patients regarding geographic atrophy (GA). Methods: A survey-based study assessed ophthalmologists’, optometrists’, and AMD patients’ perceptions and practices regarding geographic atrophy management in Spain, including disease journey challenges. Results: The study sample comprised 30 ophthalmologists, 35 optometrists, and 37 patients. A substantial majority of ophthalmologists followed a specific protocol for the management of GA, in which optical coherence tomography, visual acuity assessment, and fundus examination constituted the core diagnostic procedures. Although most HCPs reported recommending low vision aids, only 5.4% of patients reported having received such a recommendation or prescription (p < 0.001). Considerable variability among the optometrists surveyed was identified regarding visual rehabilitation programmes involving low vision aids. Furthermore, while most ophthalmologists and optometrists reported having provided various types of disease-related information, a significantly lower proportion of patients reported having received information on several aspects such as the disease itself (p < 0.001), disease progression (p < 0.001), impact on quality of life (p < 0.001), or low vision aids (p < 0.001). Multiple limitations in daily living activities were reported by patients, with those diagnosed with GA experiencing significantly greater difficulty reading television subtitles (p = 0.026) and performing manual tasks (p = 0.005). Conclusions: HCPs appear to follow specific protocols and guidelines in the management of GA; however, a potential deficit in effective HCP–patient communication has been identified that should be investigated further.
