Comparing Refractive Error with Axial Length in the Subjects Having Refractive Error

ABSTRACT

Introduction: Refractive error has now become the secondmost common cause of blindness across the world. Thereis necessity to explore the various factors having impact onrefractive errors as they will certainly assist in the variousmodes of treatment aspect of the refractive errors. This studywas carried out with the aim of comparing refractive errorwith axial length in the subjects with refractive error.Material and methods: In this study, total of 500 adult caseswere recruited. So total of 1000 eyes were examined upon.This study was carried out, over a total period of 2 years.General examination was carried out in each and every case.Afterwards, local examination was done. Then refractive errorand axial length was measured. The data obtained from thisstudy was analysed statistically.Results: The results of our present study have showed thatthe spherical refractive error has statistically highly significantnegative correlation with axial length, in right eye (r=-0.836,p<0.01) and in left eye (r=-0.859, p<0.01).Conclusion: The observation made from this study says thaton progressing from myopic to hyperopic refractive error, theaxial length of the eye is found to decrease. In the refractiveerror of shortsightedness or myopia, the final image is formedahead of retina
