Neuro-Optometric Assessment and Understanding Infantile Nystagmus Syndrome (INS) by Dr. Kwang Cham

Online Optom Learning Series (OOLS) Sessions

Dr. Kwang Cham, a practicing optometrist, researcher, and educator, begins by providing a neurological testing checklist in an optometric clinic. He tells us that we can improve our practice by doing simple neurological tests, which he describes in detail as follows

  1. Lid Function/ Ptosis workup
  2. Mental Screening 
  3. Cerebellar Function Tests 

Next, we review the cranial nerves quickly before we learn about the different cranial nerve screening tests

  1. Cranial Nerve Function 
  2. Sensory Testing 
  3. Reflex Testing

After discussing all the different neurological Testing, we learn about Infantile Nystagmus Syndrome (INS). We cover the following points in detail.

  1. Clinical features 
    1. Waveform for INS
    2. Foveation periods 
    3. Latent components and null zone 
  2. Assessment 
    1. History 
    2. Visual Testing 
    3. Eye Movement recordings
  3. Therapeutic Interventions
    1. Optical
    2. Pharmacological 
    3. Surgical 

Dr. Cham concludes the talk by presenting a few case studies and summarizing the talk’s take-home points. The session ends with a question and answer segment with the live audience.
