Flashcards in Moore-Screening/dz Deck (20):
Number one cause of bad vision in the ENTIRE population below 45?
AMBLYOPIA - 3%. More bad vision d/t this than ALL other causes COMBINED
-adults >45: glc, amd, etc.
Which countries have the lowest prevalence of amblyopia? Most likely reason?
Scandinavian countries: sweden, denmark, finland, norway, iceland
3%--> 0.2%. Lea asks if child smiles back, etc, as part of SCREENING instead of only as part of a case Hx (complete exam)
vision screening date as far back as ____. What were people looking for on Ellis island?
1861 (union army)
Trachoma! not TB...smh
VIP study results*
1) dry ret is ___% sensitive for amblyopia
2) do other screening methods (besides dry ret) raise that percentage?
3) Phase 3 results suggest what significant fact?
1) 90% --> but still misses 10%!
2) NOT MUCH, even if used in combo
3) vision and learning are related
Where is the highest per capita area in the WORLD of available ODs per patient?
Boston - and still, access to care is limited...
Name two plans that qualify as essential health benefit plans (EHBs) that are available as SUPPLEMENTARY vision benefits for children:
1) CHIP vision benefits
2) FEDVIP BlueVision High (41 states - majority)
Which 5 states do NOT require supplementation of pediatric vision care (b/c it's included in the state plan):
Maine, MA, PA, UT, CO
FEDVIP covers all of the following:
-STARDARD lenses w/ frame allowance
-LV exams (1 every 5 yrs) and f/u visits
-LV aids - but $$$ limits expenses
CHIP covers all of the following:
-screenings, exams, glasses as needed, emergency/well-child services
-up to 16 exams LIFETIME; limited frames/lenses
MAINE's non-supplemented (already existing) policy for peds:
-1 exam and refraction every year
-glasses every 2 yrs
Which condition can lead to iris strands extending to the posterior corneal surface, and commonly results in glaucoma?
-axenfeld syndrome: PE+iris strands+IOP (glaucoma likely)
-rieger anomaly: iris involvement, GLc likely
-rieger syndrome: systemic manifestations (teeth malformation)
most common location of iris coloboma?
inferior nasal (incomplete closure of fetal fissure)
T/F: assuming you have NF, lisch nodules become more likely/common as you age
true. nears 100% toward adulthood if (+)NF
A child presents w/ extreme photophobia, eye rubbing, and epiphora. Before making any observations, what are some findings you'd expect to see behind the SL?
ddx: congenital glaucoma
signs: Haab's striae, megalocornea, K clouding, Glc cupping, increased IOP
assoc w/: aniridia, sturge-weber, NF, AC-cleavage syndrome (axenfeld/rieger etc)
-REFER to pediatric Glc specialist!
Give 3 systemic manifestations of FAS:
Give 3 ocular manifestations:
systemic: growth retardation, CNS involvement, developmental delay, genito-urinary abnmlities, facial dysmorphology, cardiac/skeletal abnmlities
ocular: AC cleavage syn, ptosis, small apertures, telecanthus (wide spaced eyes), strab, high MYOPIA/astigmatism
FIRST thing you should do if you see nystagmus and possibly expect albinism?
-tyrosinase +/-, hereditary, ocular findings, cortical issues, functional issues
three key OCULAR findings seen in albinism:
2) foveal hyPOplasia
3) refraction/binocularity/HIGH Rx
more than 50% of people with WHAT kind of nystagmus have ocular albinism?
SENSORY nystagmus (d/t vision loss of ANY cause)
a TOTAL dosage of HOW MANY mLs of Pred Forte are required within 6 months to give a pt a 50% chance of developing glaucoma?
150mL w/i 6 months = 50% chance
