assessment of accommodation and convergence system in the bank employees

ABSTRACT

Regarding the high outbreak rate of the eye disorders and problems particularly accommodation disorders and convergence insufficiency in computer users, the study tries to determine the convergence, accommodation system, condition, fusion reserves and vision dimension in bank employees [who work with computers] and the control group [who are not computer users] and then to compare the mentioned parameters in the two groups. In this cross-sectional and observational study a total of 44 bank employees and 44 people as the control group members were selected randomly. Initially, refractive problems were reformed, and then accommodation, convergence and vision dimension evaluative tests were conducted. The test included measuring the near point of convergence, jump convergence, phoria, accommodation range [one eye, both eyes], ease of accommodation [one eye, both eyes], positive and negative related accommodation, near fusion versions and TNO. Our results showed that there was a not significant difference among the near point of convergence, jump convergence, near phoria, accommodation range [one eye and both eyes], ease of accommodation [one eye, both eyes], positive and negative related accommodation in bank employees and control group. Regarding the studies, the outbreak rate of accommodation and convergence disorders is higher in bank employees than the control group which would be due to over working with computer within a fixed interval
