Retinal haemorrhage

Retinal Haemorrhage

Retinal haemorrhage (pronounced: /ˈrɛtɪnəl ˈhɛmərɪdʒ/) is a disorder of the eye characterized by bleeding into the retina or the vitreous humour.

Etymology

The term "retinal haemorrhage" is derived from the Latin word "retina" meaning "net", and the Greek word "haima" meaning "blood" and "rhegnumi" meaning "to break".

Definition

Retinal haemorrhage is a condition where bleeding occurs in the retina, the innermost, light-sensitive layer of tissue of the eye. This can lead to a variety of symptoms, including sudden or gradual changes in vision, floaters, or even total loss of sight.

Causes

Retinal haemorrhages can be caused by a variety of conditions, including diabetes, hypertension, retinal vein occlusion, and trauma to the eye. They can also occur as a result of certain procedures, such as laser eye surgery, or due to certain medications, such as anticoagulants.

Diagnosis

Diagnosis of retinal haemorrhage typically involves a thorough examination of the eye by an ophthalmologist. This may include a fundus examination, where a special instrument called an ophthalmoscope is used to view the back of the eye. Other tests, such as optical coherence tomography (OCT) or a fluorescein angiography, may also be used.

Treatment

Treatment for retinal haemorrhage depends on the underlying cause. This may involve managing the underlying condition, such as controlling blood sugar levels in diabetes or blood pressure in hypertension. In some cases, surgical intervention may be required, such as a vitrectomy or laser photocoagulation.
