Functional Vision Assessment

Definition- Legally blind is having a visual acuity of 20/200 or less in the better eye even with correction such as eyeglasses or has a field of vision so narrow that its widest diameter subtends an angular distance no greater than 20 degrees. Low vision or partly sighted is persons who have low vision have visual acuity falling between 20/70 and 20/200 in the better eye with correction
Diagnosis- Visual acuity is measured with a Snellen Chart which consists of rows and letters. Functional Vision Assessment is a vision teacher observing the student interacting in different environments (classroom, outdoors, stores) under various lighting conditions to see how well a student can perform tasks and identify objects.
Causes/Characteristics - Causes:

The severity of the hearing impairment depends on where the damage took place in the ear. Conductive is when hearing loss is due to problems with the ear canal, eardrum, or middle ear and its little bones causes can be viruses, diseases, ear infections, malformation of ear structures, foreign bodies in the ear, and osteoporosis. Sensorineural is when hearing loss is due to problems of the inner ear also known as nerve-related hearing loss causes can be head trauma, exposure to loud noise, autoimmune inner ear disease, and osteoporosis. Mixed refers to a combination of conductive and sensorineural hearing loss. This means that they may be the damage in the outer or middle ear and in the inner ear or auditory

This is not due to any other disabilities. Trouble with reading and writing is very common in students with SLI. Early expressive delay refers to a significant lag in expressive language in children. About half of children will grow out of this and catch up to speed with their peers, while the other half may continue to have a language impairment for the rest of their lives. Language based reading impairment is a reading problem based on a language disorder. An example of this would be dyslexia. These disorders can be identified through research in student's abilities to be phonologically aware, knowledge of the alphabet, and grammatical speech. These categories can help identify early on If a student has a language-based reading impairment. Speech Disorders: This disorder typically occurs in children (years 9 and younger). This does not refer to the disorders by which children who are developing have an inability to say words correctly. The cause of this disorder is often unknown. Their speech sound production differs from culturally normal, appropriate, speech expectations. Children with this disability struggle to differentiate and produce phonemes or sounds in order to construct words. Articulation disorders involves errors in producing sounds. The individual omits, substitutes, distorts, or adds speech sounds such as a lisp. Voice
