Refractive errors in adults studied at a teaching hospital.
Gomal J Med Sci Jan ;13(4):223-5.

Background: Refractive errors are one of the commonest causes of visual impairment and disability. The aim of this study was to evaluate the distribution of different types of refractive errors. Material & Methods: This descriptive prospective study including one thousand and eighty seven patients was conducted at outpatient department of Ophthalmology, DHQ Teaching Hospital, Bannu, from October 2014 to March 2015. Refraction was done with Neitz streak retinoscope and Topcon auto-refractometer. Results: Among 1087 patients studied, 739(67.98%) were males and 348(32.02%) females. Age range was 25 to 80 years with a mean of 45.1. Refractive errors ranged from -14D to +10D. Myopia was the commonest refractive error found in 479(44.06%) patients, hyperopia in 286 (26.31%) and astigmatism in 307(28.20%) patients. Conclusion: Refractive errors are among the major causes of visual impairment, disability and blindness. However refractive errors are easily correctable. Effective measures should be taken for screening and refraction to combat the avoidable visual impairment and disability due to refractive errors.
