| Band Keratopathy |
Introduction and Overview
Figure 1
The term keratopathy refers to a disease or degeneration of the cornea, the clear, dome-shaped structure at the very front of the eye where light first enters the eye.

| Bell's Palsy |
Bell’s Palsy is a common form of temporary facial paralysis, affecting about one out of every 65 people, and about 50,000 North Americans each year.

| Black Eye |
When we are injured by a blow to a body part, for example, if we fall and hit an arm against a railing or other object, the likely result is a bruise, which is caused by broken blood vessels under the skin and bleeding into the tissue in the area. Swelling, a dark blue-black coloration and soreness in the area are common results. The medical term for a bruise is hematoma.
A black eye is also a bruise, and often results from a blunt blow to the area of the face around the eye or e...

| Blepharitis: Making Matters Worse |
Introduction and Overview
Blepharitis, also known as meibomian gland dysfunction (MGD), is the term used for a family of eyelid margin disorders that cause symptoms such as redness, swelling, itching or burning, dryness, crusty lids, grittiness, and even eventual loss of eyelashes. If the lashes grow back, sometimes they no longer have pigment or they grow in the wrong direction, back towards the eye, which can cause a secondary irritation to the ocular tissues.

| Blepharochalasis |
Blepharochalasis is a condition that affects the eyelids as they lose their natural elasticity in the aging process. Fluids can build up in the tissues of the lower lids and cause them to sag, and the upper lids to droop, sometimes to the extent that they may cover part of the visual axis, or line of sight. However, it is also seen in younger people, typically during puberty or who are in their early 20s.
In figure 1, we see a typical appearance of blepharochalasis; note especiall...

| Branch Retinal Artery Occlusion and Central Retinal Artery Occlusion |
We are conditioned to maintain a healthy diet and a healthy lifestyle from every direction; we usually think this is to prevent heart disease, diabetes or stroke. What most of us don’t realize is that what is happening elsewhere in the body is also happening within the eyes.
As we age, a natural plaque begins to form in the arteries that allow the blood to carry nutrients and oxygen to all parts of the body. No one is exempt from this, but it only becomes a problem if the amount o...
