pediatric nurses lay screeners
_____ ____ and _____ ____ can be experienced in working with young children, and can be trained and certified for vision screening tests. therefore they can do a very good job in administering these tests in a normal preschool environment
allen pictures tumbling E
_____ ____ are another type of recognition acuity test that uses symbols (hand, bird, cake, phone, etc.). however, these are not ideal as they do not blur equally, meaning some can be easier to see than others, and some pictures are abstract and old. the ____ _____ is another recognition acuity test that is not ideal as children might not know their directions to determine which direction this letter is pointing. these should be used only if they are the only type available. recognition acuity at near can also be done with the ATS 4
learning disabilities processes
_____ _____ are the most common childhood disorder requiring special education (affects 5-15% of school children). these can be in a wide range of subjects including math, reading, listening/reasoning, and written and oral language. we can help with the relationship between vision and learning. this term is a general one used to describe learning difficulties. the children with these can be average to above average intelligence but just have differences and how their brain works and how it ______ info. there is no cure but this doesn't say how to teach the children. these children can become high achievers but also life long learning challenges
vision
_____ disorders are the 4th most common disability in the US, and is the most frequently occurring handicapping condition of childhood. we can also use this as rationale for early screening exams
HOTV lea
_____ is another form of recognition acuity that also needs to be confirmed at near before we move to a distance. the examiner will point to one of the letters and the child can either verbalize it or match it. this different from lea as this is letters while lea uses symbols. we also found that these were very similar in picking up vision defects, however the _____ was slightly better. however, the smaller this is, it can be guessed more easily whereas the lea cannot (recall they all start looking circular)
recognition resolution
______ acuity is the gold standard for visual acuity. this is based upon the Snellen optotypes and the child must recognize, identify, or match shapes, numbers, or letters. generally this is not used in children below 3 years and instead we should begin with ______ acuity tests for birth to 2 years old, which is the clinical test of choice in babies and COGNITIVELY or actually below 3. this is easy to administer, easy to quantify, allows comparison to the other eye, and the results can be compared to a table of expecteds
InfantSEE
______ is a program developed by the AOA and was sponsored by Johnson and Johnson to help children get screenings from birth to 1 year of age using OD volunteers. in year 1 it provided 50,000 exams using 7,300 providers with public service announcements. this has a similar minimum database that includes history, VA, ocular motility, alignment/binocular potential, refractive status, external/anterior segment evaluation, visual field assessment, pupil evaluation, internal assessment, and summary
dyslexia font
_______ is the most common childhood learning disorder and is considered a 'specific learning disability'. this is difficulty with accurate and/or fluent word recognition, and poor spelling and decoding abilities, which typically result from a deficit in phonological component of language that is often unexpected in relation to other cognitive abilities & provision of effective classroom instruction. Secondary consequences may include problems in reading comprehension and reduced reading experience that can impede growth of vocabulary and background knowledge. however, a _____ was developed to try to mitigate these reading disabilities
yearly decreases
after school entry around the age of 5-6, subsequent vision exams are now recommended ______. this is because the visual system will continue to change as children are using their eyes for more detailed tasks with increased time demand on vision. eye exams and correction of refractive error also becomes very important because as children progress through education, the print ______ in size with in increase in reading to learn. recall that vision disorders can affect the way a child learns, and the performance and self esteem of the child are sensitive to these changes
risk
again we should note that these early screenings by MD's are important. this is because they detect children at _____. however, we should also note that these are NOT eye exams and they do not actually diagnose vision disorders. the children are then referred to an eye care specialist for evaluation and diagnosis.
autorefractors photorefractors/photoscreeners higher (can be static or video/powerefractor)
alternatives for the non-cycloplegic retinoscopy that can be done in a screening setting includes _____ (measures refractive error monocularly) as well as ____/______ (measures refractive error binocularly and can measure alignment) in terms of general categories. the second group shows refractive error by a crescent or brightness that appears in one eye compared to the other. this will indicate type and magnitude of RE as the brighter has a ____ RE

another disorder we want to screen for is ______. if this is left uncorrected, it can cause amblyopia and reduced or absent binocularity/stereopsis. this is also associated with psychosocial issues
refractive error amblyopia strabismus
another example is significant _____ _____, including nearsighted, farsighted, astigmatism, and anisometropia. these are the most frequently occurring disorders and the most correctable (glasses and contacts). however, if left uncorrected, it can cause _____ and _____, as well as interfering with performance. this is why this is important to screen for and detect early
9 motor environments
as optometrists, babies under _____ months of age are the easiest to examine. they like to look at lights so it is easy to get their attentions for pursuits, saccades, etc. it is also easy as these children have minimal _____ activity, have minimal stranger anxiety, and have no fear of new _____
Bruckner test lighter/brighter/whiter
another supplemental test to confirm amblyopia is the ____ test, which is done in 2 steps for strabismus and amblyopia. in step 1, the child fixates at our light as we look at both eyes with our ophthalmoscope so we can compare the reflexes to see if they are equal. if they are, we stop the test. if not, it indicates strabismus, amblyopia, or significant refractive error is present, so we go to step 2. now we would zoom in to look only at the _____ eye, and look to see if there is fixation/darkening. if yes, there is no amblyopia. if not, there is amblyopia
rapid automatized naming phonological
another way we process info is through ____ ____ ___, which is the ability to name visual stimuli quickly. this is highly predictive of future reading skills as it involves many visual, cognitive, and linguistic processes. this skill is also responsive to vision therapy. this is also another aspect of _____ processing as it is the ability to retrieve easily and rapidly verbal info held in long term memory. most children and adults with reading difficulties have pronounced difficulties when asked to rapidly name familiar symbols and objects

behavior change
because these children have better communication skills, it is ok to ask the child to cooperate with us and tell the child what we want them to do. for example, we can say things like "I need you to cooperate with me". we can also use rewards for _____ throughout the exam, but not for correct responses. for example we can use praise, stickers, or snacks from the parents. _____ is also helpful, whether it be our voice, movement, or the test, especially if the child is being uncooperative
motor
beyond 6 months of age, the children begin to develop more _____ control and start sitting up more easily. they can also interact with the examiner and can do "peek a boo". we should be careful as these children like to grab lights and can begin to crawl at 7 months. because of this, we should allow the babies to remain in their car seat or stroller, or even in the parents lap during the exam

binocularity has both motor and sensory components: Motor: - how the eyes look - cosmetic appearance - eye contact - bonding - closer alignment- easier to achieve sensory binocularity sensory: - what the eyes see - fusion - stereopsis - visual development - orientation and mobility - behavioral responses
dyseidetic auditory
boder also described the _____ group of dyslexia which is defined as a deficiency in the ability to perceive letters and whole words as configurations or visual gestalts. they also read laboriously as if seeing each word for the first time (have to sound it out each time), and have difficulty learning what the letters look like. these people spell by ear, not by sight, and are therefore more ____ learners
mixed visual
boder also identified a ____ category which include people that are deficient in both areas (language and visual processing). these people have the most severe reading problems and their response to standard remediation is poor. if we take into account that boder said 22% have this problem while 9% have dyseidetic problems, then he states that 33% have ____ processing deficits

detection acuity stycar candy beads
one lower form of acuity that we do not use as often is _____ acuity, which determine whether an object of specified size and distance can be seen. this is typically only used when other methods are unreliable. one downside is that optical blur can actually increase visibility of this and has little correlation to snellen. one form of this is using ____ that involves motion, or ____ ____ but are difficult to quantify
communication behavior
other special considerations are that infants and toddlers have very little ______ skills, and so we need to use different procedures. they also cannot tell us if something is wrong but may communicate through their _____ (i.e. squinting may mean they cannot see), and so we must be aware of what is normal and what is not. it is important to remember the "critical periods" of visual development where intervention at an earlier age can result in better outcomes
language dysphonetic
others have categorized dyslexia differently. Mattis found that 47% had a _____ component, 37% with graphomotor, and 16% with visuospatial. Boder however found that 63% had a ____ component, 9% with dyseidetic, and 22% mixed

so how do we know what works? there was a study called the _____ in _____ ____ ____ ____ that aimed to identify the best tests by looking at 15 different screening tests by licensed eye care professionals (MDs and ODs) that were both experienced in pediatric care. they did so with a mobile medical unit in order to provide a controlled environment. all the children had a comprehensive, cycloplegic eye exam by these providers with standardized testing procedures, and doctors did not know the screening results
1. noncycloplegic retinoscopy 2. retinomax autorefractor 3. SureSight vision screener
so in terms of refractive error screening tests, we found that these 3 tests that assess refraction perform better than tests that use photorefraction, for example the iScreen photorefractor, MTI photorefractor, and power refractor. we also learned at lay screeners and nurses performed equal to doctors with autorefraction and sensitivities close to doctors with retinoscopy

lea symbols
the ____ ____ is one type of recognition acuity test that is calibrated for distance and near. some of these have crowding bars but they all have equal blur. as the optotypes get smaller and smaller, they all begin to appear like a circle instead of the various shapes. the child needs to get 3/3 or 3/4 in order to move to the smaller line and may be used in both a screening and threshold phase
broken wheel
the _____ ____ is another recognition acuity test that is done at 10 feet (can also be landolt C's). this also takes into account crowding and is a form of forced choice where the child looks at two cars and will move their gaze to one of them. the child needs 4/4 o4 4/5 to move to the next smallest acuity
Krimsky
the _____ test is used to estimate the deviation with prism. basically once we see the hirschberg is misaligned, we can use prism to see how much it takes to align them

more separation anxiety
the children's visual systems are developing rapidly and therefore we need to use different criteria when managing vision disorders. for example children at birth have very poor visual acuity, so we would not worry as much. however, because of this rapid development, we need to monitor them ______ frequently and discern if the changes are normal changes or vision disorders. as they begin to get older, they may also fear new environments/strangers, fatigue easily, and may have _____ _____ from their parents
teller acuity cards forced choice preferential looking
the gold standard test to do resolution acuity is the ____ ____ _____, which have good reliability and be can completed by most infants and toddlers. these are are also useful in children with a variety of visual disorders and developmental disabilities. they can also be used with non-verbal adults. another test for resolution acuity is the ____ ____ ___ ____ in which we present patterned stimuli as a behavioral test in where the task is based on the ability of the child to resolve gratings and their preference for patterns. the VA is then based on the spatial frequency of lines. the basis for decision is based on the child's first fixation and duration of fixation, and behavioral responses
fatigue interest booster seat

retinoscopy 50 cm 0.75 D 1.25 D
the near retinoscopy was developed by mohindra and is useful for children from birth. here we use a dark room with the retinoscope as our light source. the child then fixates on the _____ and we use a lens rack or loose lenses to neutralize the refractive error. this is done at _____ cm and can use sound effects to maintain the child's attention. we also must use a correction factor for this, which is _____ D for less than 2 years, and _____ D for greater than 2 years. note: we can also do distance retinoscopy in older infants where they would direct they're attention to a distance target
fix and follow test tropias strabismus
the next lower test is the ____ and _____ test, which is used to assess the presence of vision. this is thought to detect significant levels of amblyopia and is used by many eye care provides for VA. despite this, however, it is inaccurate for measuring VA, and has a high false negative rate of 60-80% and therefore can miss amblyopia with or without small ______. it also has a high false positive rate of 31-68% especially with large angle _____. it may also be insensitive to changes with patching in amblyopia

there are also some special considerations when dealing with infants. the younger the patient is, typically the ______ they are to examine due to "babe in arms". they also like to look at _____ up to 6 months of age which helps us. they are also typically very sleepy, and have a short attention span. we should also allow a bottle or pacifier to make the exam go smoother
alternate fixation 10 prism diopter vertical prism
there are also supplemental tests we can use to confirm amblyopia. for example we can do _____ _____ testing in which they change fixation from right to left. if each eye gets used, it is less likely amblyopia developed. another supplemental test is a _____ ____ ____ ____ ____ test. here prism is placed over the childs eye, causing the image to dissociate, and watch the patients eyes to see if are alternating fixation between the two images (which would be a good sign)

HOTV lea symbols 10 or 20 5
there are two primary optotypes that are used for children. these are the ______ visual acuity and the ____ ____ visual acuity. however, we also need to determine which format was best as well as which testing distance was best. traditionally, the test would be done at _____ or _____ feet. however, this presents a challenge as the mobile units and other spaces may not be this big. recently it was switched to _____ feet (could potentially miss kids with low myopia, but low myopia is not very common in children of this age). the type of patch was also examined
eye exams
there is also controversy as to what is the best way to find and treat common vision problems in children. one way to do so is to conduct a _____ ____, in which the purpose of this is to detect, diagnose, and then begin treatment for eye and vision disorders. however, this is not done on most children (which is a problem because recall many children have vision disorders). infantSEE is a problem established to help get children these exams
VIP (vision in preschoolers)
there was also a landmark study on preschool vision screening called _____, which is a group of clinicians and researchers from across the country interested in preschool vision screening, and in particular learning the best ways to screen. they also empower communities by working with nurses and lay screeners, as well as working with different community needs and budgets such as high tech vs low tech. their study was done in 5 mobile vision vans as it made it easier for children and families to participate in terms of providing access
6 treatment
therefore the first comprehensive vision exam takes place at ____ months of age, when we know that most systems are well developed. at this point the babies will be in the parents arms so they are easy to examine. in addition, they will be entertained by simple things, so _____ is easier and more effective. recall that these early screenings will also help us to prevent secondary problems such as amblyopia
discrepancy cutoffs
therefore the major premise is that a significant _____ exists between the child's potential and actual level of academic or language skills. each state, however, may determine _____ for discrepancies or definitions of processing disorders, leading to variability among states and even differences among districts within a given state (people can actually move to a different state to obtain different services).

these comprehensive eye exams in the vision in preschoolers study part 1 were used to classify children as either normal or having one or more of these 4 conditions
sensitivity specificity
these screening tests must be able to detect most children with a problem, meaning it has to have a high _____ (close to 90%). this is the probability that a test will indicate the condition among those actually with the condition. however, this alone is not enough. the test should also not over-refer too many children, meaning it has high ______ (close to 90%). this is the percentage of those without the condition who will have a negative test result
reading transient transient system deficit
these system's major function is _____, which involves fixations (sustained for extracting details) and saccades (transient) so we can integrate the information between our eye movements. the role of the ____ system diminished the persistence effect of sustained channels by erasing pattern information from the previous fixation (basically if we look at one word when reading, and then move to the next, we have to erase the previous word imagery otherwise they will appear on top of each other - this is what happens in a LD and words can look very jumbled, called a ____ _____ _____)
1. very important to detect and treat early 2. important to detect early 3. detection is clinically useful

we also use _____ ____ which is our ability to integrate info from various sensory modalities. these can be ______ factors, which are from the same source, for example visual and visual pattern matching, or they can be _____ factors, which are from a different source, for example auditory and visual. this is the best way to learn as it reinforces and internalized knowledge
targets parent and child
we have to be flexible when working with children. we can change tasks when necessary, meaning we do not always have to do VA first like in adults. we also want to make sure we are using age appropriate _____ for our tests, and ensure we are proficient in these tests for children. also know what happens when with regard to visual development and age expected levels of visual skills. it is important to develop a caring, trusting relationship with both the _____ and ____. it is also ok to bring the child back if needed for a follow up visit for example if the child is scared, and use stickers and prizes if they do well for encouragement
ocular motilities visual acuity
we must also examine _____ _____ in the children. we can do so by using pursuits, saccades, and position maintenance. for targets, we can use puppets, lights, mirrors, and the examiners face, but recall we can change the targets when necessary. the parents can also hold the child's head if needed. if these are abnormal, it may be due to decreased _____ _____, nystagmus, or neurological involvement
stereopsis 3 figure flashlight
we test sensory binocularity through _____, in which any age appropriate random dot test is ok to use. this includes the PASS test, random bot butterfly, lang, randot preschool stereoacuity test, and TNO (red green filters). in addition to this, we can also measure fusion. typically we measure this using the worth 4 dot, but in order to do this the patient must be able to count. therefore for kids we can use the ____ ____ ____, where the child only has to identify shapes. here the child wears R/G glasses (red over right eye) so the the right eye sees the red girl image, the left eye sees the green elephant image, and both eyes see the white ball. using this we can determine which eye is being suppressed

we think of learning disabilities as a ______ population, meaning they can have one or more of language, speech, auditory, cultural, motor skills, attention, emotion, visual perception, and/or academic deficiency components
ocular health refractive accommodation binocularity ocular motility
what goes good vision mean? when we talk about visual acuity, we are only talking about the clarity of a picture. if we have good VA (20/20), then we know that there is good ____ ____ in the macular area and _____ status is good. however, beyond VA, we also know there are other components of vision, such as _____, _____, and ____ _____ that affect the clarity, comfortability, and efficiency of our vision. this is known as visual efficiency
common treat detect
what kinds of vision disorders are we trying to detect? we are looking for ______ disorders that may not be obvious and may be a significant public health concern. we also are looking for disorders that are easy to _____ and ______, as the earlier we do this the better the outcome will be for the children
regression 10%
when a person is reading a sentence silently, the eye movements show that not every word is fixated. every once in a while a _____ (an eye movement that goes back in the test) us made to re-examine a word that may not have been fully understood the first time. this only happens with about ___% of the fixations, depending on how difficult the text is. the more difficult, the higher the likelihood that these occur
cost referral criteria
when choosing a screening test, we must consider the _____ of the test, as well as the number of children to be screened/budget. we must also pick a test that has been proven to work in studies with large numbers of children, larger numbers with targeted vision disorders, and includes vision disorders important for that population. we also need good ____ ____
testability specificity sensitivity
when choosing a screening test, we want to have high ____, high _____, and high ____. this is because we need these tests to pick up important vision disorders and be used by the designated screener
1-2 3
when do we see the child next after their 6 month old exam? children between the ages of ____-____ years old are notoriously difficult to examine. this is because they have increased motor activity, extreme stranger anxiety, and lights are no longer interesting to them. these children also have limited attention as well as limiting communication and language skills. therefore, we will do our second comprehensive eye exam around _____ years of age. this is because the child will be more cooperative, and their language skills are more developed. however, if a child has never been seen or has a vision problem, we should see them regardless of their age
1-2% 3% 1.5%
when looking at strabismus overall, in the 4% that have strabismus, congenital esotropia makes up about ___-___%, esotropia about ___%, and exotropia about ____%

birth screening
when should we do our first vision assessment? these typically take place at _____ when in the hospital in which they look at the ocular structures and clarity of the media to see the red reflex to ensure the eye is in tact. rarely this can be preformed by optometrists at the hospital, but typically is performed by pediatricians and/or OMD. it is important to keep in mind this is a ____ only, not an eye exam
adhesive patch (narrow part up and nasal) unequal amblyopia
when testing visual acuity in children, our preferred method of occlusion is a ____ ____ that is applied monocularly to the correct eye. the parent may need to hold the child's hand so that it is not taken off. there are also three main reasons we want to do visual acuity. these including determining if there is reduced VA, but also if there is _____ unequal and to detect _____
1. illuminated 2. high contrast 3. at least 1 inch in diameter note: want to avoid toys that make sound
when we have children look at targets, we want them to have these 3 characteristics (other than mirrors and faces)
breaks engaging varied
when working with young children, we should also allow short ______ during the exam, especially if they are getting anxious or tired. beyond 1 year of age, the child is now known as a "toddler". now our targets have to be both _____ and _____. we should also be cautious as they are grabbing things, fidgety, whining, they tire easily, and respond to treats from the parents
vision disorders
why do we care about development? this is because _____ _____ are associated with many conditions and affect development. in addition, delayed development may affect the visual development. for example, children with cerebral palsy are at high risk for strabismus, or, if a child has very high myopia, they may not develop fine motor as they cannot see up close
