Educational Visual Impairment Eligibility

The educational definition of visual impairment, as outlined by IDEA, determines eligibility for special education services and the need for specially designed instruction to access the educational curriculum across multiple settings. Unlike medical definitions of visual impairment, the educational definition does not stipulate any diagnostic criteria measurements (e.g., visual acuity such as 20/70, a visual field such as less than 20%) nor diagnosed eye condition. While it is best practice to ask for an eye report during the assessment for eligibility and reevaluation process, one cannot be required, nor can a visual acuity and/or visual field range be stipulated.

While medical treatments such as vision therapy are not provided in the school setting, associated supportive accommodations to facilitate learning may be implemented.
According to the May 2017 Office of Special Education Programs Memorandum “Eligibility Determinations for Children Suspected of Having a Visual Impairment Including Blindness under the Individuals with Disabilities Education Act,” students whose vision is suspected of “adversely affecting their educational performance (e.g., ability to read and write)” may not be excluded from being evaluated for a visual impairment. This includes students with visual conditions that traditionally have fallen under the practice of vision therapy, such as convergence insufficiency. However, the May 2017 memorandum does not require that all students that are evaluated for a suspected visual impairment qualify for services, nor does it state the nature and extent of the educational accommodations and/or services to be provided. In addition, it does not state that treatment and remediation of the disorder must be provided by the school. It is up to the LEAs to determine whether the students’ visual impairments may be adversely impacting their education and thereby need to be referred for a visual impairment evaluation by a TVI.

It is important to be aware that:
  • Common conditions treated through vision therapy have the potential to impact a student’s educational performance. Students undergoing vision therapy may exhibit symptoms such as poor reading comprehension, inability to read for long periods of time, loss of place and skipping lines when reading, seeing double images, and headaches associated with reading.
  • Students receiving vision therapy through a medical professional and also found to be eligible for special education based on visual impairment would not receive vision therapy services from a TVI. Rather, the TVI would provide visual impairment services that are determined by educational vision-based assessments (e.g., FVA, LMA, ECC) and IEP/IFSP/504 team decisions.
