OBJECTIVE

• To find out the prevalence of uncorrected refractive errors

in presbyopes attending Eye OPD in medical college in

Bangalore

• Uncorrected refractive error in presbyopes is the second most common cause of treatable Visual Impairment in this age group worldwide

• In India about 35 million people in presbyope age group are visually impaired due to uncorrected refractive error (WHO 2004 bulletin)

• Average coverage of refractive services in India is just 40-55%

• This study aims to find out the prevalence in our clinic settings

INTRODUCTION

MATERIALS & METHODS

MATERIALS & METHODS

• Workup done by same post-graduate student• Preliminary data included age, sex• History was taken regarding:

– Diminision of vision for distance, near or both– Any spetacle usage (past or present)

• Complete ophthalmic examination was done including:– Distance / Near Visual Acuity– Objective Refraction & Subjective Refraction– Slit Lamp Examination– Fundoscopy

RESULTS

DISCUSSION

LIMITATIONS OF THE STUDY

• Small Sample Size• Presbyopes with amblyopia / ocular disease /

surgery / trauma were not included

CONCLUSION

• A significant population of presbyopes have uncorrected refractive errors

• Complete refraction of every presbyope patient should be performed

• Outreach programmes should infiltrate the refractive services into the general population

• Affordable refractive services should be developed
