Purpose: Amplitude of accommodation varies with race and ethnicity and Hofstetter’s
equations are commonly used in Nigeria to calculate expected amplitude of accommodation for clinical purposes. The aim of this study was to present normative values for amplitude of accommodation for Nigerian children and to compare the measured values with
those calculated using Hofstetter’s equations.
Methods: A total of 688 children aged six to 16 years from three selected cities in Nigeria
were included in the study. Push-up technique was employed to measure the amplitude of
accommodation. The measured values were compared with the calculated values
(Hofstetter’s equations) using the paired t-test and Bland and Altman plots.
Results: The measured amplitude of accommodation for the subjects ranged from 8.00 to
25.00 D with a mean of 15.88 3.46 D. The calculated minimum amplitude of accommodation ranged from 11.00 to 13.50 D with a mean of 12.09 0.55 D and the calculated
average amplitude of accommodation ranged from 13.17 to 16.50 D with a mean of
14.62 0.73 D. The calculated maximum amplitude of accommodation ranged from
18.60 to 22.60 D with a mean of 20.34 0.88 D. The t-test indicated a significant difference between the measured and calculated minimum, average and maximum amplitudes
of accommodation (p < 0.0001). Also, the Bland–Altman plot suggested that there was a
lack of agreement between the measured and calculated amplitudes of accommodation.
Conclusion: The mean values of amplitude of accommodation in this study are different
from those reported in the literature. Also, the measured values differed from the calculated values using Hofstetter’s equation. This suggests that the use of Hosftetter’s equations to predict amplitude of accommodation may not be accurate for Nigerian children.
At Amplify with Dr Wernick I was seeking help for seemingly intractable, probably age-related dryness. I've seen other doctors about it, and that has been helpful, but what he explained to me about it and the careful way he answered all my questions gave me so much more of a clear understanding of what is going on (and is not) that I am more able to implement all his and others' recommendations than I was before. And he gave me additional resources for further follow-up. I am most grateful.
Wow! This is a great Eye Care medical facility. I was thoroughly examined by Dr. Pinkhasov for over 2 hours. She made sure to check my eyes for pretty much everything and patiently explained proper care for my eyes. They definitely know how to provide great care and treat their patients right. Now I know why they have such a great reputation and been around for so long.
Dr. Kavner is a gifted diagnostician and orthoptic therapist. He treated me several decades ago for a condition similar to dyslexia. I was having migraines five times per week. I worked with him for about a year and I experienced tremendous improvement (down to 3-4 per year) that has lasted.
Dr. Kavner recommended two types of eye therapy for my daughter. One of them using bio-feedback. In just three sessions she is seeing considerably better. She shouted this morning: Ooh my God! I could not see these letters with my glasses on, and now I can see them without my glasses. If you are willing and able to invest in improving your vision, this is a good place to go to!

I have always found Dr Kavner's work, expertise and wisdom of the highest caliber. As one of the fathers of OT, occupational othomology, his depth and breadth of knowledge about the eyes' health and wellbeing of the patient is exemplary. Cannot say enough good things about him.
