• Diabetic retinopathy —most common cause
• Retinal tear or detachment
• Posterior vitreous detachment
• Trauma or injury to the eye

• Blurriness or haziness
• Shadows
• Seeing red
• Vision loss

Vision problems may worse in the morning.

Diagnosis

The doctor will ask about your symptoms and health history. A physical exam will be done. An eye exam will be done.

A slit-lamp will be used to view the back of the eye to look for signs of bleeding. Some people may have an ultrasound instead.

Treatment

Most people get better without treatment. The doctor will monitor a person for changes. Others will need to have the underlying cause treated.

Some people may need surgery. Vitrectomy may be done to remove the hemorrhage.
