What is a Visual Impairment?

According to the Centers for Disease Control and Prevention (CDC), approximately 6.8% of children younger than 18 years in the United States have a diagnosed eye and vision condition and 3% of children younger than 18 years are blind and visually impaired. Visual disability is one of the most prevalent disabilities disabilities among children.

According to IDEA’s definition, visual impairment is defined s including blindness means an impairment in vision that even with correction, adversely affects a child’s educational performance. The World Health Organization (WHO), classifies visual impairment as occurring when an eye condition affects the visual system and one or more of its vision includes both partial sight and blindness

Classifications

The World Health Organization uses the following classification based on visual acuity in the better eye:

  • 20/30 to 20/60- mild vision impairment
  • 20/70 to 20/160- moderate visual impairment
  • 20/200 to 20/400- severe visual impairment
  • 20/500 to 20/1,000- profound visual impairment
  • More than 20/1,000- considered near-total visual impairment
  • No light perception- considered total visual impairment or total blindness
Types of Visual Impairment
  • Strabismus– a condition when the eyes do not align with each other (crossed eyes)
  • Congenital cataracts– a clouding of the eyes natural lens present a birth.
  • Retinopathy of prematurity– a blinding disorder that affects prenatal infants that are born before 31 week of gestation.
  • Coloboma- a condition where normal tissue in or around the eye is missing at birth.
  • Cortical visual impairment– a visual impairment that occurs due to brain injury.
Signs of Visual Impairments
  • Appears “clumsy” in new situation
  • Shows signs of fatigue or inattentiveness
  • Does not pay attention when information is on the chalkboard or reading material
  • Is unable to see distant things clearly
  • Squints
  • Eyes may appear crossed
  • Complains of dizziness.
Causes

The causes of childhood blindness or visual impairment is often caused by Vitamin A deficiency which is the leading cause of preventable blindness in children. Other causes include genetics, diabetes, injury and infections such as congenital rubella syndrome and chickenpox before birth.

Cortical Visual Impairment (CVI)

Cortical Visual Impairment in children is attributed to brain dysfunction rather than issues with the eyes. Causes included hypoxia, traumatic brain injury, neonatal hypoglycemia, infections and cardiac arrest.

Cerebral Palsy Training PowerPoint

This blog article is an introduction to cerebral palsy. In the past, very few educational programs offered courses on specific information pertaining to disabilities. I am hopeful this is beginning to change.  Ions when I started working in the field, I felt that there was simply not enough information so I started to do my own research by reading books, journal articles and talking to both professionals and parents.

Here, I have included a short PowerPoint presentation on a brief introduction of Cerebral Palsy. The objectives include, the definition, prevalence and causes, types and the causes. This format can be used in various ways including a teaching course since most of us are currently learning online, or as a self-study course. Below,  you will find a quiz along with the quiz answers.

COVID-19 and Handwashing Powerpoint

Most news today whether it is social media, newsprint or broadcasting, focuses on the crisis of the COVID-19. It seems information changes everyday and we are still learning ways to protect ourselves. When the news of COVID-19 first appear, there was emphasis on the implications for people who have severe underlying conditions  such as heart or lung disease and diabetes. The picture painted were people that were over the age of 65 who were more likely to be at risk for developing serious complications from COVID-19.

It occurred to me that very little information indicated that people with disabilities and special risk also fall under the high risk category. for us who are parents or professionals  (in some cases both), we know the dangers of this deadly disease for children and adults with serious medical issues.

Many special needs children and adults have co-occurring issues including chronic heart disease, GI issues, diabetes, asthma, seizure disorders, GERD, and breathing issues.

For this reason, it is all the more reason to ensure that professionals, frontline staff and families know how to hand wash properly.  The Powerpoint focuses on the transmission of the virus as well as the appropriate way to wash hands. You will find the link to the Powerpoint at the bottom of the page.

Strategies In Training Dyslexic Employees

According to the Learning Disability Online website, It is estimated that 1 in 10 people have dyslexia which is between 5 to 15% of Americans.

What is Dyslexia?

Dyslexia is also known as a language-based disability. It is defined as difficulties with accurate and word recognition and by poor spelling which can affect reading fluency, reading comprehension, recall, decoding, writing, spelling, and sometime speech. Signs of dyslexia in adults include:

  • Poor spelling
  • Avoids writing task
  • Gifted and creative
  • Difficulty in following oral and written instructions
  • Difficulty staying on task
  • High level of frustration
  • Difficulty in retaining information
  • Test-taking anxiety.
  • Highly curious
  • Insightful
  • Curiosity
  • Good communication of stories read to them

American Disabilities Act

Employees diagnosed with Dyslexia are protected under the American Disabilities Act (ADA) which prohibits discrimination in all employment practices, including job application procedures, hiring, firing, advancement, compensation, training and other terms, conditions and privileges of employment. It applies to recruitment, advertising, tenure, layoff, leave, fringe benefits, and all other employment-related activities.

Disability Definition

The American Disabilities Act defines disability as a physical or mental impairment that substantially limits one or more major life activities such as seeing, hearing, eating, sleeping, walking, learning, reading, concentrating, thinking, communication and working.

Challenges in training employees with Dyslexia

recalling information

following instructions

May experience anxiety from test-taking

Reading takes longer

Training Strategies

People with dyslexia are visual learners. They learn best by seeing, watching, and observing. When training, use pictures, computers, PowerPoint and text.

Multisensory training helps the employee to use all senses when learning something new on thejob. Multisensory learning should include combining all senses including visual, auditory, tactile and kinesthetic.

Use demonstration when possible and give feedback whenever possible.

Accomodations

A diagnosis of dyslexia also qualifies under the American Disability Act (ADA).  While some may not want to disclose their diagnosis, It’s always a good idea to make sure each person is comfortable in the training. The following are some suggestions:

  • Asking a participant diagnosed with dyslexia to read out loud can be tricky and make them feel uncomfortable
  • If your organization gives, test, look for alternatives such as allowing time to complete the test longer or giving a test orally.
  • Too much information may be overwhelming. Make sure instructions are clear.
