Objective:

To share clinical insights and strategies for effective prism prescribing in managing binocular vision disorders, emphasizing the importance of patient feedback.

Key Findings:

• Classic prescribing rules have strengths and limitations, and trial framing and patient feedback are crucial.
• Evidence shows limited objective benefit of prism in children with convergence insufficiency, but adults often find symptomatic relief.
• Fresnel prisms can be useful for trialing despite reduced acuity and contrast sensitivity.
• Yoked prisms may improve balance in traumatic brain injury patients.

Interpretation:

The findings suggest that while traditional rules exist, personalized approaches and patient feedback are crucial in effective prism prescribing.

Limitations:

• Limited objective evidence for prism efficacy in children with convergence insufficiency.
• Potential reduction in acuity and contrast sensitivity with Fresnel prisms, particularly in certain contexts.

Conclusion:

A systematic approach to prism prescribing, incorporating patient feedback and careful testing, can enhance treatment outcomes for binocular vision disorders, reflecting the blend of science and art in the process.
