“…The factors of “positive affect” (such as loneliness, good, enjoyment, and hopefulness) in the depression scale (CES-D) and VA both predict the functionality of daily living with a variance of 31.1%. In a recent study, depression along with gender and vision coping, also appeared to be strong predictors, explaining 35.2% of the variance in a QoL test [ 82 ]. In general, LV is associated with lower levels of psychosocial well-being, manifested by loss of interest and enjoyment in physical activities [ 83 ].…”

Background. Low vision (LV) has a significant negative impact on the activities of daily life as well as on the psychological health of patients. Objectives. The objective of this study is to investigate psychological, clinical, and demographic factors that may impact the daily functionality of patients with LV. Methods. A convenience sample of 53 patients, meeting the WHO criteria for LV, was recruited. Questionnaires on daily functionality, depression, and life orientation (in terms of optimism/pessimism) were administered along with a semistructured personal interview. Key Findings. The main results revealed a significant negative correlation between daily functionality and depression (r=−0.423, p<0.001). Conversely, there is a positive correlation between daily functionality and visual acuity (r=0.415, p<0.001), while years since diagnosis were negatively correlated with depression (r=−0.345, p<0.001). Depression seems to be a moderate predictor of a person’s daily functionality (β=−0.389, p<0.002), followed by visual acuity (β=−0.344, p=0.006), explaining the 31.1% of the total variance. Conclusions. The study supports a correlation between daily functionality and both depression and visual acuity. Optimism as a personality characteristic did not factor into the prediction model for daily functionality, but it showed a strong correlation with lower levels of depressive symptoms. This highlights the potential for developing coping strategies for chronic disease management. Recommendations. The study could serve as a useful guide and may urge clinicians to pay attention to the psychological evaluation of these patients, supporting their unique emotional needs. Mental health professionals can use patients’ positive resources to provide appropriate counseling and embrace the coping skills that encourage their engagement in activities of daily life.

“…Ghodasra et al (2016) suggest that the rehabilitation team that assesses candidates may have a positive effect: Farvardin et al (2018) found that a multidisciplinary approach by a cross-functional team optimizes strategies and leads to better user outcomes. Moreover, the literature (Bentley et al, 2019; Markowitz et al, 2018) suggests that psychosocial factors be considered in candidate selection. Also, there seems to be a lack of appropriate assessment methods for this client group.…”

Introduction Various retinal implants are being developed and appear to be a promising option for improving the visual capacities of individuals with retinal dystrophy. A multidisciplinary approach to both assessment of a candidate’s factors and rehabilitation could contribute to improved activity and participation. The purpose of this study was (i) to document the approach taken by a multidisciplinary team in the candidate selection process and in training in the use of the Argus II retinal prosthesis system (RPS), and (ii) to examine the effects of the RPS on sensory and mental functions and on activity and participation. Methods An A1-B1-A2-B2 experimental case report was used, with repeated measures pre- and post-rehabilitation program design. The A phases represent the periods with the system off, whereas the B phases represent the periods with the system on. A 65-year-old man with retinitis pigmentosa and total blindness was followed by a multidisciplinary team for over 18 months. After receiving the retinal implant, he benefited from a 10-week rehabilitation program (twice per week; B1 phase). Results Globally, the RPS improved vision in the B phases when the system was on and visual acuity was stable at 2.3 logMAR (functional blindness). The participant’s mental and neuromusculoskeletal function scores were generally stable throughout the data collection periods. Lower performance on some measures at the end of phase B2 coincided with a negative mood. Discussion Use of the RPS improved activity, but this did not transfer into greater participation in the living environment. Despite efforts made by the rehabilitation team to manage the user’s expectations concerning the RPS, the interventions reactivated his grieving over his vision loss. Implications for Practitioners New technologies can make users dream of unrealistic possibilities, and managing their expectations requires problem solving supported by a multidisciplinary team.
