Occupational Therapy in Low Vision

OT & Low Vision - Vision Navigators

• OTs as "Vision Navigators": guide patients with low vision.
• Goal: Enhance independence in Activities of Daily Living (ADLs) & improve Quality of Life (QoL).
• Key Functions:
  • Comprehensive functional vision assessment.
  • Evaluating impact on ADLs & Instrumental ADLs (IADLs).
  • Client-centered goal setting.
• Intervention Strategies:
  • Training: use of optical & non-optical aids.
  • Techniques: eccentric viewing, visual tracking.
  • Environmental modifications: ↑contrast, optimal lighting.
  • Task adaptation & assistive technology.

⭐ OT's primary aim in low vision is to improve participation in desired occupations (activities) by addressing functional limitations.

OT Assessment - Insight Inspectors

• Comprehensive Patient Interview:
  • Understand patient's specific goals, daily challenges (ADLs/IADLs).
  • Assess psychosocial impact of vision loss.
• Functional Vision Assessment:
  • Evaluate how remaining vision is used in real-world tasks.
  • Key tests: Contrast sensitivity, glare recovery, functional visual fields (e.g., Amsler, confrontation).
• Environmental & Safety Assessment:
  • Evaluate home, work, or school environments.
  • Identify fall hazards, lighting issues, and accessibility needs.
• Task Analysis:
  • Direct observation of patient performing problematic activities.
  • Break down tasks to pinpoint specific difficulties.
• Standardized & Non-Standardized Tools:
  • Questionnaires (e.g., VFQ, COPM).
  • Performance-based measures.

⭐ OT assessment is client-centered, focusing on individualized goals and real-world functional performance rather than just clinical vision metrics.

OT Interventions - Life Hack Heroes

• Goal: Maximize independence & safety in Activities of Daily Living (ADLs) & Instrumental ADLs (IADLs).
• Core Strategies:

  • Environmental Modification:

    • ↑ Lighting (task-specific, ambient), ↓ glare.
    • ↑ Contrast (e.g., dark plate on light placemat, bright tape on step edges).
    • Organization: decluttering, consistent placement of items.
    • Marking: tactile cues, large print labels.

  • Task Modification & Adaptive Equipment:

    • Simplifying tasks, breaking into manageable steps.
    • Adaptive devices: magnifiers (handheld, stand, electronic), talking devices (clocks, glucometers), large button phones, needle threaders, liquid level indicators.

  • Sensory Substitution & Training:

    • Enhancing use of other senses (touch, hearing, smell).
    • Auditory cues, tactile markers.

  • Eccentric Viewing Training:

    • Teaching use of preferred retinal locus (PRL) for scotoma.

  • Psychosocial Support & Coping Strategies.

⭐ Exam Favourite: Eccentric viewing training is crucial for patients with central scotomas (e.g., Age-related Macular Degeneration) to utilize their remaining peripheral vision effectively.

📌 Mnemonic: “SEE IT” for OT goals:

• Safety
• Environmental mods
• Equipment (adaptive)
• Independence
• Training (skills, sensory, eccentric viewing)

Psychosocial Support - Empathy Engines

• Addresses emotional sequelae of vision loss: anxiety, depression, social isolation.
• OT Role:
  • Facilitate emotional adjustment & coping mechanisms.
  • Build therapeutic rapport (core "empathy engine").
  • Enhance self-efficacy & active participation.
• Interventions:
  • Counseling (individual, family, group).
  • Peer support groups: shared experiences, mutual understanding.
  • Stress reduction techniques; problem-solving skills.
  • Referral to mental health professionals if needed.

⭐ Significant rates of depression (approx. 33%) and anxiety are reported in adults with age-related macular degeneration (AMD).

High‑Yield Points - ⚡ Biggest Takeaways

• OT in low vision aims to enhance functional independence and safety.
• Key interventions: environmental modifications (e.g., lighting, contrast), adaptive equipment training (magnifiers, CCTVs).
• Teaches compensatory visual strategies like eccentric viewing and scanning.
• Central to OT: ADL/IADL assessment and task-specific training.
• Provides psychosocial support and training in task modification.
• Ultimate goal: Improve participation in desired activities and overall Quality of Life (QoL)_
