Objective assessment of accommodation orthoptics. I. Dynamic insufficiency

Area of Science:

• Neuro-optometry
• Vision Science
• Orthoptics

Background:

• Focusing difficulties at near affect young adults.
• Standard orthoptic procedures are used for treatment.

Observation:

• Three young adult females with near focusing issues were treated.
• Objective measures assessed dynamic accommodation weekly.
• Initial measures showed prolonged accommodation time constants and latencies.

Findings:

• Orthoptic treatment included jump focus, lens flippers, and pencil pushups.
• Patients underwent daily home training for 4.5-7 weeks.
• Significant reductions in accommodation time constants and latencies were observed.
• Flipper rates increased, and symptoms diminished or resolved.

Implications:

• Orthoptic treatment objectively improved accommodation function in adult patients.
• This demonstrates the efficacy of vision therapy for convergence insufficiency and related issues.
• Further research can explore long-term effects and broader applications.
