    Bell's Palsy. What Is Bell's Palsy And How Does It Affect The Eyes?

    Above picture from health.clevelandclinic.org


    This condition is named after the Scottish surgeon Charles Bell who first described the disease in the early 1800s. It is a paralysis of the facial nerve on one side of the face, resulting in a facial droop similar to that found in stroke patients. The paralysis often affects the upper eyelid and the side of the mouth on the affected side. This means the person may not close the eye, control salivation, taste the food, cry, smile, frown, or close their lips on the affected side.

    Asteroid Bodies. Not A Space Thing.

    Some patients have in the back fluid of the eye the presence of asteroid bodies.  Two-thirds of the volume of the inside of the eye is filled with a clear jelly-like mass called the vitreous body.  Think of the vitreous as you would the air in a balloon.  In the eye, the vitreous pushes up against the retina to keep it in place.  Asteroid bodies are tiny, usually numerous, floaters /spots commonly found in the vitreous fluid.  They generally occur in one eye and patients over the age of 60.  Although it has never been confirmed that this ocular condition has a general health relationship, it should be noted that approximately 33% of patients with this finding also have diabetes and 60% have hypertension.
