hearing/vestibular/ear
• membranous labyrinth is collapsed
• cross sections of the crista ampullaris, macula utricle, and macula sacule are all normal
|
• measurable response only at the highest intensity tested, 75db
• longer response latencies
• reduced central conduction time
|
• reduced potentials with prolonged latencies for later peaks
• elevated thresholds
|
vision/eye
• basal epithelial layer more columnar than for controls
• basal layer cell height higher than for controls
• cornea otherwise normal when examined under broad beam illumination
