Suspecting multiple sclerosis she consulted a neurologist who documented counting fingers vision with a normal examination. A magnetic resonance imaging (MRI) scan performed the same day clearly demonstrated a macular off-retinal detachment (fig 1), which was subsequently successfully repaired with a scleral buckle.

This unusual case, in which a retinal detachment was diagnosed with an MRI scan, illustrates a valuable point. A hand-held ophthalmoscope, with its high magnification, small field of view and lack of stereopsis, does not permit sufficient retinal views to rule out ocular pathology. Shallow retinal detachments, macular oedema, central serous retinopathy and macular degeneration, for example, are difficult to identify with a direct
