Indirect opthalmoscopy detects A,/E

D i.e. Examination of fovea Don't get astonished, this is the right answer. All the structures given in options can be examined by indirect ophthalmoscope. But indirect ophthalmoscope is almost never used for examination of fovea, as it provides only 5 times of magnification and the image is inveed (direct ophthalmoscope provides 15 times magnification, erect image and the instrument is cheap, handy and easily available). And the vitreous base (a 3-4 mm wide zone straddling the ora serrata) ora serrata, retinal peripheray can only be examined by indirect ophthalmoscopyQ. Indirect ophthalmoscopy The higher the power of condensing lens, the lower the magnification, the shoer the working distance but the greater the field of view. Scleral indentation enhances visualization of peripheral retina anterior to equatorQ and enables a dynamic fundus examination. Ora serrata, vitreous base and small u-tearsQ may be overlooked without scleral indentation.
