Eye Conditions

Microvascular Cranial Nerve Palsy (MCNP) is when the blood flow of cranial nerves in your head is blocked. As a result, you may not be able to move your eye a certain way.

Giant cell arteritis (GCA) is an inflammation (swelling) of the arteries, which are the blood vessels that carry blood away from the heart.

Histoplasmosis is a disease that can develop when you breathe infected airborne spores into your lungs. The spores that cause it come from the fungus Histoplasma capsulatum.

Uveitis occurs when the middle layer of the eyeball gets red and swollen. This layer, called the uvea, has many blood vessels that keep the eye nourished.

Eye floaters are spots that move through your field of vision. They can often appear as black or gray spots that drift as you move your eyes or when you try to look at them directly.

A substance called a glassy substance is filled in the middle of the eye. The vitreous tissue is usually attached to the retina, on the back of the eye.
