Retinal haemorrhage
Retinal haemorrhage is a disorder of the eye characterized by bleeding into the retina. It can occur as a result of various medical conditions, including diabetes, hypertension, and blood clotting disorders.
Causes[edit | edit source]
Retinal haemorrhage can be caused by a variety of conditions, including:
- Diabetes: High blood sugar levels can damage the blood vessels in the retina, leading to bleeding.
- Hypertension: High blood pressure can cause the blood vessels in the retina to burst, resulting in a haemorrhage.
- Blood clotting disorders: Conditions that affect the body's ability to clot blood can lead to bleeding in various parts of the body, including the retina.
Symptoms[edit | edit source]
The symptoms of retinal haemorrhage can vary depending on the severity of the condition. They may include:
- Blurred vision
- Floaters: Small specks or clouds moving in your field of vision.
- Vision loss: This can be partial or complete.
- Pain: This is not a common symptom, but it can occur if the haemorrhage is severe.
Diagnosis[edit | edit source]
Retinal haemorrhage is typically diagnosed through a comprehensive eye examination. This may include:
- Visual acuity test: This test measures how well you can see at various distances.
- Dilated eye exam: Drops are placed in your eyes to widen, or dilate, the pupils. This allows the doctor to examine the retina and other parts of the eye more thoroughly.
- Fluorescein angiography: A dye is injected into a vein in your arm. The dye travels through the blood vessels in your eye, making them visible in photographs taken with a special camera.
Treatment[edit | edit source]
Treatment for retinal haemorrhage depends on the underlying cause. It may include:
- Laser surgery: This can be used to seal leaking blood vessels and prevent further bleeding.
- Vitrectomy: In severe cases, surgery may be needed to remove blood from the inside of the eye.
- Medication: Drugs may be used to control conditions that can cause retinal haemorrhage, such as diabetes and hypertension.
