Clinical effect of low vision aids

Area of Science:

• Ophthalmology
• Low Vision Rehabilitation

Background:

• Increasing life expectancy leads to a rise in low vision prevalence.
• Growing socioeconomic status and media development increase demand for low vision aids.

Purpose of the Study:

• To evaluate the effectiveness of low vision aids in improving visual acuity and patient satisfaction.
• To identify common causes of low vision and frequently used assistive devices.

Main Methods:

• Retrospective review of clinical records from 118 patients attending a low vision clinic.
• Analysis of best-corrected visual acuity (BCVA) with and without low vision aids.
• Assessment of patient-reported functional difficulties and satisfaction levels.

Main Results:

• Common causes of low vision include optic nerve atrophy, retinal degeneration, diabetic retinopathy, and age-related macular degeneration.
• Low vision aids improved visual acuity to >0.4 in 87% for near vision and 56% for distant vision.
• 70% of patients reported increased satisfaction with vision after using low vision aids.

Conclusions:

• Low vision aids are highly effective in enhancing visual function for patients with various causes of vision impairment.
• Specific devices like magnifiers and telescopes are beneficial for near and distant tasks, respectively.
• Assistive low vision devices significantly improve quality of life for individuals with low vision.
