<prompt> Magnification in Indirect ophthalmoscopy a Depends on power of lens usedb Depends on refractive error of patientc Independent of refractive error of patientd independent of power of lens usedacaabbc  <response>: Magnification of image in indirect ophthalmoscopy depends upon:-Dioptric power of the convex lensThe position of the lens in relation to the eyeballRefractive state of the eyeballAbout 5 times magnification is obtained with a 13 D lens. With a stronger lens, the image will be smaller, but brighter and field of vision will be more.
