What is choroidal metastasis?
Choroidal metastasis is a seed of cancer that started in a cancer elsewhere in the body and spread to the eye by bloodflow. The majority of choroidal metastases originate from breast cancer in women and lung cancer in men.
Which cancers metastasize to eye?
The two most common cancers that spread to the eye from another organ are breast cancer and lung cancer. Other less common sites of origin include the prostate, kidney, thyroid, skin, colon lymphoma and leukemia.
What is a choroidal mass?
Choroidal osteomas are benign, rare bony tumors of the choroid. They are typically unilateral, peripapillary in location and yellow/orange in color with well-defined borders. They are usually relatively flat but may be elevated. B-scan shows high reflectivity with shadowing, consistent with bone.
Can eye cancer go undetected?
Eye cancer can grow undetected for some time, but most forms of eye cancer are relatively rare. In many cases, cancers of the eye do not spread to other parts of the body.
What is choroidal hemangioma?
Choroidal hemangioma is an uncommon benign vascular tumor of the choroid that can be circumscribed or diffuse. Circumscribed choroidal hemangiomas are usually diagnosed between the second to fourth decade of life when they cause visual disturbances owing to the development of an exudative retinal detachment.
Can a tumor grow eyes?
Malignant teratomas are known as teratocarcinomas; these cancerous growths have played a pivotal role in the discovery of stem cells. “Teratoma” is Greek for “monstrous tumor”; these tumors were so named because they sometimes contain hair, teeth, bone, neurons, and even eyes.
What does a choroidal detachment feel like?
When the choroid is detached from the back wall of the eye, patients may not feel anything at all, or may feel that the eye is achy and sore. In some cases, a choroidal detachment can cause more severe pain.
What are the complications of choroidal detachment and hemorrhage?
Complications of Choroidal Detachment and Hemorrhage may lead to vision abnormalities and may include: Choroidal neovascularization (CNV): An abnormal development of blood vessels in the choroid, which if left untreated can result in permanent loss of vision
How is choroidal detachment and hemorrhage diagnosed?
A healthcare professional may diagnose Choroidal Detachment and Hemorrhage using the following tests and procedures: Fundoscopic (ophthalmoscopic) examination by an eye specialist, who examines the back part of the eye (or the fundus) Visual acuity test using a special and standardized test chart (Snellen chart)
What does a choroidal detachment in the eye look like?
Small choroidal detachments often pass unnoticed because they affect only the region of the pars plana ciliaris and the retinal periphery, and subside spontaneously. 3 Postoperative choroidal detachment appears as a solid, immobile orange-brown elevation of the fundus ( Fig. 14.2 ).
