The tic-like movements and swelling of the third ventricle associated with bobble-head doll syndrome are similar to that of other movement disorders caused by diseases of the corpus callosum and aforementioned basal ganglia. Because of the swelling, added pressure is applied to these formations causing their basic functions to be disturbed.
A pseudocyst is a cystic lesion that may appear as a cyst on scans, but lacks epithelial or endothelial cells. [4] An acute pancreatic pseudocyst is made of pancreatic fluids with a wall of fibrous tissue or granulation. [citation needed] Pseudocysts may form in a number of places, including the pancreas, abdomen, adrenal gland, and eye.
Finally, lymphangiomas may be described in stages, which vary by location and extent of disease. In particular, stage depends on whether lymphangiomas are present above or superior to the hyoid bone ( suprahyoid ), below or inferior to the hyoid bone ( infrahyoid ), and whether the lymphangiomas are on one side of the body ( unilateral ) or ...

There are many diseases known to cause ocular or visual changes. Diabetes , for example, is the leading cause of new cases of blindness in those aged 20–74, with ocular manifestations such as diabetic retinopathy and macular edema affecting up to 80% of those who have had the disease for 15 years or more.
Cluster headache is a neurological disorder characterized by recurrent severe headaches on one side of the head, typically around the eye(s). [1] There is often accompanying eye watering, nasal congestion, or swelling around the eye on the affected side. [1] These symptoms typically last 15 minutes to 3 hours. [2]
Ferrets with Waardenburg syndrome have a small white stripe along the top or back of the head and sometimes down the back of the neck (known as a "blaze" coat pattern), or a solid-white head from nose to shoulders (known as a "panda" coat pattern). Affected ferrets often have a very slightly flatter skull and wider-set eyes than healthy ferrets.
This arrangement allows the left half of the visual field to end up on the right side of the brain and the right half of the visual field to locate to the left side. The optic nerves consist of the axons from the retinal ganglion of each eye. At the chiasm, 53% of the axons from the nasal retina cross the midline to join the uncrossed temporal ...
