|Common Birth to 3 Eye problems
||failure of the halves of the eye to join completely inutreo, may affect pupil, retina or lid
||varies depending of retinal damage
||glare problems if pupil is affected and retina is functional, reduced bincular depth percpetion
||sunglasses, motor practice
|Optic Nerve Hypoplasia
||decreased evelopment of the optic nerve, usually assocaied with midbrain/endocrine problems
||varies from minimal affect to near blindness, possbile field cut, possble nystagmus
||Delayed motor development due to reduced visual input. Refer to TVI at 3 yrs old.
||vestibular and motor facilitation tasks.
|Retinopathy of Pre-Maturity
||scarring related to excessive blood vessel growth during prolonged O2 exposure in premature infants
||varies by amount of scarring
||depends on level of scarring, may be no delays related to vision
||based on acuity
|Corticol Visual Impairment
||lack of vision due to visual pathway damage/failure to develop
||Usually not 100% blind
||near blindness, refer to TVI,
||use contrasting colors, movment and work peripheral to central to investigate amount of vision. Referal to TVI is important for school readiness.
||medial eye turn due to extreme farsightedness
||20/20 with glasses in place, eye turn also corrects with glasses
||improves, but child will remain in glasses throughout life
||none with early correction, amblypoia without correction
||glasses should be comfortable and worn at all times.
||medial eye turn not related to
||generally reduced due to amblyopia, may improve with correction
||varies, tx by surgery vs VT vs Botox
||reduced motor development
||per doctors order concerning patching, facillitate motor improvement
||reduced acuity due decreased visual pathway development due to prolonged suppression or lack of stimulation to visual pathway
||varies, 20/200 or worse to 20/50 depending on patching complaince and glasses wear compliance.
||may improve with compliance of tx and glasses wear, binocular vision therapy
||reduced motor dev., head turns, decrease binocular depth perception. Brain with compensate in time
||motor dev facilitation, exercise amblyopic eye if currently patching, binocular vision activities
||eye mis-alignment at rest, corrected with surgery vs VT vs Botox
||varies, generally reduced due to amblyopia
||varies greatly. Long term, brain adapts to suppression of the turned eye
||reduced motor dev, self-esteem, self conscious of turned eye, reduced binocular depth perception
||eye exercises per doctors order, facilitate motor development
