PMID 36968165WHAT IT FOUND
Inpatient vision rehab protocols for hemineglect, field cuts, and nerve palsies were feasible for therapists and perceived beneficial for 63% of patients.
This describes a service model and survey opinions. It does not prove the treatments work.
Key findings
01Over five years, 2083 unique patient vision consults were provided, with hemispatial neglect, homonymous hemianopia, and oculomotor cranial nerve palsies being the most common diagnoses.
02Occupational therapists reported that the diagnosis-specific protocols were feasible to deliver and that 63% of their patients benefited from them.
03Therapists reported that press-on prisms helped many or all patients with nerve palsies for 42% of respondents, while Peli lenses for field cuts were perceived to help a few patients for 55% of respondents.

What it does not show
The study is retrospective and descriptive; it does not include a control group or objective outcome measures to determine efficacy. The primary data on patient benefit comes from therapist surveys, which are subjective and unvalidated for research purposes. Only about 10% of the total admitted population was seen by the vision service, meaning the sample represents a subset of patients referred for vision issues, not the general inpatient population. There were inconsistencies in how therapists applied protocols, with some using interventions for inappropriate diagnoses (e.g., prism adaptation for right neglect), which may skew the reported benefits. The survey response rate was 31 out of an estimated 33 relevant therapists, but the overall invitation list was 66, and the study relied on practice leader estimates of who actually used the protocols.
Declared interests
The authors declare that the study was conducted as part of a clinical quality improvement process. No specific commercial funding sources or conflicts of interest are explicitly detailed in the provided text beyond the institutional nature of the work.
The easy way to misread this
Do not interpret the 63% reported patient benefit as evidence that these vision rehabilitation protocols are proven effective. This figure comes from a subjective survey of occupational therapists who knew the patients and the interventions. The study had no control group and did not measure objective outcomes, so it cannot rule out spontaneous recovery or placebo effects.
