A stye is a small, red, painful lump that grows from the base of your eyelash or under the eyelid. Most styes are caused by a bacterial infection.
There are two kinds of styes:
- External stye: A stye that begins at the base of your eyelash. This is most likely caused by an infection in the hair follicle. The appearance resembles a pimple.
- Internal stye: A stye inside your eyelid. Most likely caused by an infection in an oil-producing gland in your eyelid.
A stye can develop if you have blepharitis. Blepharitis is a condition that makes your eyelids at the base of the eyelashes red and swollen.
When a stye develops, your eyelid is probably red and tender to the touch. The eye may feel sore and scratchy.
A chalazion is a swollen bump on the eyelid. This happens when the eyelid’s oil gland clogs up. It might start as an internal stye. As a chalazion gets larger, it can press on the eye and cause blurry vision. Possibly, the whole eyelid might swell.
Symptoms of a stye:
- Painful red bump along the edge of the eyelid at the base of the eyelashes. The entire eyelid might swell.
- A small pus spot at the center of the bump.
- Feels like something is in the eye.
- A scratchy feeling in the eye.
- Sensitivity to light.
- Crustiness along the eyelid margin.
- Tearing in the eye.
Symptoms of a chalzion:
- Bump on the eyelid, sometimes becoming red and swollen. Occasionally it can be tender.
- Rarely an entirely swollen eyelid.
- Blurry vision should the chalazion become large and press on the eyeball.
Treatment for a stye or chalazion:
- Warm compresses
- Steroid Shots
- Surgery to drain the area
