A Study on Amplitude of Accommodation in Different Refractive Condition in Bengali Population
Journal Title: IOSR Journal of Dental and Medical Sciences (IOSR-JDMS) - Year 2018, Vol 17, Issue 4
Abstract
Accommodation is a dynamic change in the dioptric power of the eye. The mechanism of accommodation has been studied for at least 400 years. But how the amplitude of accommodation varies with different refractive status (emmetropia / myopia / hypermetropia) is not much studied so far. So we conducted this study comprising of 600 eyes belonging to 300 healthy Bengali people of different age group of either sex in a tertiary level hospital, for a period of one year. After a routine ophthalmic examination and full distance correction, the near point of accommodation was measured, one eye at a time, using RAF rule by Duane’s method. Observation led us to conclude that highest amplitude of accommodation was observed in myopes followed by emmetropes and hypermetropes. Although the gradual and steady decrease in amplitude of accommodation with age was similarly marked, irrespective of different refractive condition.
