Abstract/Introduction

Background: While there have been extensive

studies of the amplitude of accommodation (AA)

in adults, estimates of AA from studies in children

between 5 and 10 years of age vary widely with some

of the data being contradictory. Further, since values

of AA are used for the diagnosis of several conditions

including accommodative insufficiency (AI), it is

important to able to compare clinical findings with

age-defined norms.

 

Methods: The present study was performed on

60 asymptomatic children between 5 and 10 years of

age. Each child was refracted for distance viewing, and

both push-up (PU) and push-down (PD) amplitudes

were recorded monocularly using a Royal Air Force

(RAF) nearpoint rule. Four readings (2 PU and 2 PD)

were taken on each subject. The same procedures were

also carried out on 38 adult subjects between 20 and

50 years of age.


Conclusion/Results

Results: The mean findings (average of PU and

  1. PD) declined from 16.2D (SEM=1.7D) at 5 years of

age to 12.4D (SEM=1.4D) at 10 years of age. A twophase regression was observed, with a rapid decline

between 5 and 7 years of age, but minimal change

between 7 and 10 years of age.

 

Conclusions: Both the pediatric and adult data is

broadly similar to the classic findings of Donders and

Duane. However, a relatively high percentage (36%)

of children met the most commonly adopted criterion

for AI, suggesting that this standard may need to be

reexamined in this particular age group


Testimonials


  • Such a nice optician. My grandson is only 4 and needs glasses. We were so sad, but he explained the issues, and we will follow up as he suggested.


    Anna P.

  • I had such a good experience with the clinic. Very friendly staff and doctor, did not have to wait for long to be called, and was treated respectfully. Thanks, American Family.


    June S.

  • Dr. Zurcher has gone above and beyond what any other eye doctor has ever done to figure out what is going on with my eyes. Very happy with American Family Vision.


    Christine R.

  • Family Vision Clinic changed our lives! My daughter was frequently car sick, and she was getting headaches every day, often painful enough that they brought her to tears. We saw a string of doctors and therapists, but we made no progress. Finally, we found Dr. Levi Zurcher and his eye therapist Rain. After ten weeks of eye therapy my daughter no longer gets headaches, and she no longer gets car sick. Daily tears are a thing of the past. I really can’t say enough about this clinic. It was fascinating to watch Dr. Zurcher work. For the first time, someone who knew what they were doing was intently studying my daughter, really trying to figure out all of her eye issues, and his therapist Rain is one of the most patient and lovely people that I’ve ever had the good fortune to meet. We’re finished with eye therapy—yay!—and I have switched to American Family Vision Clinic for all of my family’s other eye health needs.

  • Very professional, yet kind and helpful. They do what they can to make the appointment comfortable. I was running a bit late, I made sure ti call. They were able to switch me with a patient who was already there, they treated me with respect, and helped my son have confidence by getting him the eye care he needed that day. Thank you so much! Would recommend to anyone. It's a blessing that they care enough to work with people who have all different types of insurance from work to state coverage.
