Eye disease associated with blood disease

For many patients, an eye exam not only allows the detection of eye lesions caused by systemic disease but also helps to confirm diagnosis, prognosis or evaluate the results of systemic treatment.

The eyes are closely related to the other organs of the body. Many systemic diseases with eye manifestations and many eye conditions may be signs of systemic illness.

For many patients, an eye exam not only allows the detection of eye lesions caused by systemic disease but also helps to confirm diagnosis, prognosis or evaluate the results of systemic treatment.

Most blood diseases can cause damage to the eyes, mainly to the retina.

Red blood cell diseases

Anaemia: pale conjunctiva, pale retina and vascular system, white-centred retinal haemorrhage (Roth's stains), subconjunctival haemorrhage, exudate, cotton stains. Severe anaemia can lead to nerve atrophy.

Polycythemia vera: darker retina, dilated and zigzag veins, haemorrhage, retinal oedema, prickly oedema. There may be central vein obstruction of the retina or neuropathy ischemic.

Sickle cell disease: In this disease, deformed red blood cells block small blood vessels of the peripheral retina, causing retinal ischemia, neovascularization, retinal haemorrhage, and vitreous proliferation. Retinal. The end result is retinal detachment.

Leukaemia

Leukaemia mainly damages many parts of the eye, especially structures with a lot of blood supply such as the retina, the retina, the optic nerve.

The anterior part of the eyeball: haemorrhage (eyelid, sub-conjunctival, anterior chamber), diffuse infiltrates (conjunctiva, sclera, cornea), iritis, scleritis.

Black and retina: dark retinal infiltration, retinal varicose veins, retinal haemorrhage with white centre (Roth's stain), microvascular aneurysm, peripheral retinal neovascularization.

Neurology: pupil disorder, ophthalmic paralysis, oedema, neuropathy.

Outside the eyeballs: infiltrates of the tear glands and lashes, inflammation of the tear glands, bulging eyes.

Diseases of the platelet line

Thrombocytopenia: may cause retinal haemorrhage.

Thrombocytosis: the risk of retinal embolism.

Increased blood consistency

Increased blood consistency due to many causes (increased red blood cells, multiple myeloma, macroglobulinemia) reduces blood flow to the eye, causing retinal damage such as retinal arteries and veins, haemorrhage, aneurysm, embolism.
