Uncorrected Refractive Error in Presbyopes


Published on

Uncorrected refractive error in presbyopes pose a significant problem. We hereby publish our results of screening of 100 presbyopes in which 47% were found to have uncorrected refractive error.

Uncorrected Refractive Error in Presbyopes

  1. 1. FREE PAPER – KSOC 2009 Uncorrected Refractive Errors in Presbyopes attending medical college Eye OPD Presenting Author : Dr. Ankit Punjabi (D.O.M.S. 2nd yr) Co-Authors : •Dr. N.V.V. Himamshu (Prof & Head) •Dr. H.N. Sowbhagya (Professor) •Dr. Mrinmayee Ghatak (D.O.M.S. 2nd yr) Department of Ophthalmology, Kempegowda Inst. of Med. Sciences Bangalore
  2. 2. OBJECTIVE • To find out the prevalence of uncorrected refractive errors in presbyopes attending Eye OPD in medical college in Bangalore
  3. 3. • 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
  5. 5. 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
  6. 6. RESULTS 53% 47%
  7. 7. RESULTS
  8. 8. RESULTS 11% 30% 21% 17% 17% 4% Visual Acuity in Presbyopes with uncorrected refractive errors VA - 6/6 VA - 6/9 VA - 6/12 VA - 6/18 VA - 6/24 VA - 6/36
  9. 9. RESULTS
  10. 10. 70% 30% Present or past spectacle usage in presbyopes with uncorrected refractive errors Not using Spectacles Using spectacles RESULTS
  11. 11. DISCUSSION
  12. 12. LIMITATIONS OF THE STUDY • Small Sample Size • Presbyopes with amblyopia / ocular disease / surgery / trauma were not included
  13. 13. 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
