Objective:

To investigate the role of orthoptic assessments in the early and accurate diagnosis of Progressive Supranuclear Palsy (PSP).

Approach:

Key Findings:

• Orthoptic assessments aligned with final neurological diagnoses in over 80% of cases (21 out of 26 patients).
• Approximately 75% of patients flagged by orthoptists as having suspected PSP received a confirmed diagnosis.
• Eye-tracking technology was effective in detecting subtle early abnormalities specific to PSP.

Interpretation:

The findings suggest that orthoptic eye movement testing can provide valuable diagnostic clarity for PSP at an early stage.

Limitations:

• The study involved a small sample size of 26 patients.
• Results may not be generalizable to all populations with atypical neurological symptoms.

Conclusion:

Earlier diagnosis through orthoptic assessments allows patients to access supportive therapies sooner.
