Abstract:
Inner ear malformations are frequently found in patients with congenital hearing loss. It has been reported that normal hearing is rare in patients with severe inner ear vestibular malformations. A 9-year-old boy had had complained of recurrent dizziness and disequilibrium for 2 months. Clinical and neuro-otological examinations showed peripheral involvement of the vestibular system, while audiological investigation was normal. High-resolution magnetic resonance imaging, with three-dimensional reconstruction, showed dysplasia of the bilateral lateral semicircular canals (LSCCs). Isolated vestibular malformation might not be as rare as previously thought, and should be examined by imaging of the temporal bone.

The retina is composed of several layers and contains specialized cells called photoreceptors. The photoreceptors (rods and cones) change their membrane potential when stimulated by light energy. There are two types of photoreceptors—rods and cones—which differ in the shape of their outer...
