Many people have experienced styes or have at least heard of it. But what really is a stye? How can we prevent or treat them?

A stye is a bacterial infection which involves one or a few of the glands at the base of your eyelashes. Often, it resembles a boil or a pimple, it may have a white head and be tender to the touch. Styes can be caused by buildup of Meibomian gland secretions or be idiopathic in nature (unknown cause). In rare worst-case scenarios, recurrent styes in the same spot can be a sign of sebaceous gland carcinomas.

It’s important to maintain good eyelid hygiene by using eyelid cleansers and warm compresses daily. This not only helps to prevent styes, but also alleviates symptoms related to dry eye and eyelash mites.

With styes, patients typically notice pain and discomfort that disappears within a few days. However, more serious cases can develop into pre-septal cellulitis with progressively worsening symptoms and require antibiotics.

Warm compresses help to speed up recovery and relieve discomfort, but if you don’t see improvements after 48 hours, you’ll want to contact your optometrist.

Did you know that diabetes is one of the most common causes of blindness?

You may be surprised to learn that optometrists can detect diabetes before primary care doctors and before the patient even knows they have it. This is because the eye is the only organ in our body where we can directly see blood vessels without invasive techniques. Since many systemic diseases affect our arteries and veins, the eye is a great way to look into what is happening inside our body.

Diabetes is becoming an epidemic in North America, and it is important to be aware of its effect on ocular health. Once diagnosed with diabetes, it becomes much more important to receive yearly eye exams, to monitor for diabetic retinopathy. This is a condition in which buildup of sugar in the blood causes blockages or damage to blood vessels, resulting in decreased oxygen supply to the eye. To compensate, new blood vessels develop. However, instead of helping, these new blood vessels are weak and leaky, leading to retinal bleeding. Although a diabetic eye exam is very similar to a regular comprehensive exam, there is more emphasis on inspecting the health of the retina and blood vessels.

How will I know if I have diabetic retinopathy?

Symptoms like floaters, blurred or fluctuating vision, dark spots in your vision, and vision loss could be signs of diabetic retinopathy.

Fortunately, there are ways to prevent diabetic retinopathy. Some of these preventions include:

  • Yearly eye exams with your optometrist (even if you think your vision is fine!)
  • Controlling blood sugar, blood pressure, and cholesterol
  • Proper dosage and compliance of medication provided by your Family Physician
  • Engaging in regular daily activity and exercise
  • Eating a balanced and nutritious diet to maintain healthy body weight
