A CLINICAL STUDY OF AXIAL MYOPIA USING OPHTHALMIC A-SCAN ULTRASONOGRAPHY

Journal Title: Journal of Evidence Based Medicine and Healthcare - Year 2019, Vol 6, Issue 11

Abstract

BACKGROUND Myopia is the most common refractive error that affects all the age groups. Axial length is the primary factor for the determination of myopia and the purpose of this study is to measure the axial length in myopic patients using A-scan ultrasonography and study their correlation with various entities. The aim of this study was to find axial length in myopic patients using A-scan ultrasonography in patients above 20 years of age group. MATERIALS AND METHODS Data of 100 patients (200 eyes), who were all myopic above 20 years of age attending our OPD from December 2016 to May 2018 was analysed. The measurement of axial length was performed respectively in 200 eyes by A- scan ultrasonography. Three to four readings were taken for each eye. Keratometry reading was taken and readings noted in millimeter. A detailed slit lamp biomicroscopy and fundus examination with direct, indirect ophthalmoscopy and 90D was done. RESULTS The axial length of myopic eyes varies from 22.86 mm to 31.81 mm using A-scan ultrasonography. There was significant increase in axial length with advance in age. There is increase in mean axial length with increase in degree of myopia. The degenerative changes and complications increased with increase in axial lengths. CONCLUSION Axial length increases with increase in age and increase in myopia. It was also found that myopia is higher in females than males.
