pressure: Do not do if there is
concern regarding globe
Things To Think About When Assessing
 Younger males are at higher risk for serious
injury
 School-age children are more susceptible to
conjunctivitis

abrasions and infection
 Exposure to arc welding S/S develop 4-8 post
exposure
Things To Think About When Assessing
 Auto mechanics and service station attendants have
potential for acid burns to face
 Injuries occurring in the garden have increased
potential for infection

Age-related Pearls
Pediatric



Delayed presentation due to children not noticing gradual
vision loss
May need picture chart
Infants and small children may need to be restrained in
blanket to facilitate exam
Age-related Pearls
Geriatric



Vision diminishes gradually until 70 y/o and then rapidly
thereafter
Decreased near vision
Decreased accuracy of results from visual acuity testing
Age-related Pearls
Geriatric
 Decreased
accommodation
to distances

 Cataracts: at age 80 1 in 3
are affected
