LOW VISION CLINIC

OUR APPROACH

Through our low vision clinic we aim to optimize the vision of patients suffering from low vision. In cases where the vision cannot be improved, we aim to train the patients on how to improve their quality of life with the help of low vision aids. At our Low Vision clinic, a multidisciplinary team of doctors and rehabilitative specialists works closely with the patient and family to assist an individual in regaining functionality lost by visual impairments. This typically includes addressing vision issues causing problems with reading, driving and activities of daily living.

OUR PROCESS

A typical low vision evaluation involves a functional assessment including a low vision refraction to find out the problem and its extent. Once the impairment is identified, suitable vision aids such as magnifiers, telescopes and other appropriate assistive technologies are prescribed to maximize the patient’s vision. The patient is then gradually trained on how to use the low vision aids to conduct various daily activities. In addition, visual skills training such as eccentric viewing, blindness skills and referrals to comprehensive blind rehabilitation centers are provided.

OUR SKILLS & TALENTS

The team is extremely understanding and helpful when it comes to counseling patients with low vision. They also advise on alternative career options and learning methods for the needy.

Dr. Vandana Nath is an expert in the field of cataract and low vision rehabilitation. She has a rich experience and has authored many research papers.

FAQS

What is ‘Low Vision’?

Basically, “low vision” describes significant visual impairment that can’t be corrected fully with glasses, contact lenses, medication or eye surgery. It includes

  • Loss of best-corrected visual acuity (BVCA) to worse than 20/70 in the better eye.
  • Significant visual field loss. Tunnel vision (lack of vision in the periphery) and blind spots are examples of visual field loss.
  • Legal blindness. In North America this is 20/200 or less central visual acuity in the better eye with best possible correction, or a visual field of 20 degrees or less.
  • Almost total blindness.
What are the causes of ‘Low Vision’?
  • Eye diseases are a common cause of low vision:
  • Hazy, blurry vision can result from cataracts.
  • Blurred or partially obscured central vision is typical of macular degeneration.
  • Diabetic retinopathy causes blind spots, blurriness and visual distortions.
  • Poor peripheral vision is a hallmark of glaucoma.
  • Retinitis pigmentosa reduces peripheral vision and the ability to see in the dark.
  • Light sensitivity and loss of contrast are other symptoms of these and other diseases.
  • Heredity and eye injuries also can result in low vision.
What are ‘Low Vision Aids?’

Low Vision Aids are tools that help those with vision loss maximize their remaining vision and these devices fall into one of three broad categories:

  • Optical devices
  • Electronic devices
  • Non-optical devices

  • Dome magnifiers
  • Fresnel book magnifiers
  • Pocket magnifiers
Which are Non-optical low vision aids?
  • Notex
  • Typoscope
  • Letter writer
  • Signature guide
  • Talking watch
  • Braille slate and style
