What Are Dot Hemorrhages?

Dot hemorrhages are tiny spots of bleeding within the retina, the light-sensitive layer at the back of the eye. They appear as small, round red dots when viewed during an eye exam. These hemorrhages occur when the tiny blood vessels in the retina leak or rupture, allowing small amounts of blood to collect in the deeper retinal layers.

Although they are often harmless on their own, multiple or recurring dot hemorrhages can be signs of underlying health conditions such as diabetes or hypertension.

What Causes Dot Hemorrhages?

The main causes of dot hemorrhages are systemic diseases that affect blood circulation.

  • Diabetic retinopathy - High blood sugar weakens retinal vessels, causing them to leak.
  • Hypertension - High blood pressure increases strain on vessel walls, leading to small ruptures.
  • Blood disorders - Conditions affecting clotting or platelet function can increase bleeding risk.
  • Eye trauma - Physical injury or strain occasionally results in retinal bleeding.

Types of Retinal Hemorrhages

While dot hemorrhages are common, other types may appear depending on where bleeding occurs in the retina:

  • Blot hemorrhages - Larger and deeper than dot hemorrhages, often seen in moderate diabetic retinopathy.
  • Flame-shaped hemorrhages - Appear in the nerve fiber layer and resemble small streaks or flames.
  • Preretinal or subhyaloid hemorrhages - Larger, surface-level bleeds that can obscure central vision.

What Are the Symptoms of Dot Hemorrhages?

Most dot hemorrhages do not cause noticeable symptoms. However, if several develop or appear near the macula, vision can become blurred or distorted. People with chronic conditions such as diabetes should schedule regular eye exams, as early retinal bleeding is often detected before vision changes occur.

How Are Dot Hemorrhages Treated?

Treatment focuses on managing the underlying cause. For diabetic patients, controlling blood sugar and blood pressure helps prevent new hemorrhages. Regular monitoring and follow-ups with an ophthalmologist are needed. Severe or persistent bleeding may require laser therapy or medication injections to reduce leakage and protect the retina from further damage.

FAQs on Dot Hemorrhages

Are dot hemorrhages dangerous?

A few are usually harmless, but many can signal vascular problems that need medical care.

Do dot hemorrhages go away on their own?

Mild ones often clear naturally once the cause is treated.

Can contact lenses cause dot hemorrhages?

No, contact lenses do not cause retinal bleeding. These hemorrhages occur inside the eye, not on the surface.

When to See Your Doctor

If a routine eye exam reveals dot hemorrhages, you should consult your primary care physician to check for underlying systemic issues like diabetes or high blood pressure. These small bleeds are often the first visible sign of diabetic retinopathy, which requires careful management to protect your sight.
