Macular hard drusen in the right eye. 65-year-old diabetic woman. Drusen, from the German word for node or geode (singular, "Druse"), are tiny yellow or white accumulations of extracellular material that build up between Bruch's membrane and the retinal pigment epithelium of the eye.
These can include nasal step defects, enlarged blind spots, arcuate scotomas, sectoral field loss and altitudinal defects. [6] Clinical symptoms correlate to visibility of the drusen. [ 13 ] Central vision loss is a rare complication of bleeding from peripapillar choroidal neovascular membranes .

Cochlear hydrops preferentially affects the apex of the cochlea where low-frequency sounds are interpreted. Due to the fluid imbalance in this area, parts of the cochlea are stretched or under more tension than usual, which can lead to distortions of sound, changes in pitch perception, or hearing loss, all usually in the low frequencies.

Conductive hearing loss is present when the sound is not reaching the inner ear, the cochlea. This can be due to external ear canal malformation, dysfunction of the eardrum or malfunction of the bones of the middle ear. The eardrum may show defects from small to total resulting in hearing loss of different degree.
